Direct answer: what a Juniper access point refresh actually involves

Why an access point refresh should not be treated as a like-for-like hardware replacement

A wireless refresh often begins with a simple business instruction: replace old access points. The technical reality is broader. An enterprise AP is only one element in the client-to-application path. Its useful performance depends on radio design, AP placement, antenna characteristics, switch port speed, PoE delivery, copper cabling, VLAN and DHCP design, authentication, Internet reachability to cloud services, endpoint capability, firmware policy and how the operations team monitors service after cutover. Replacing a previous-generation device at the same ceiling point with a newer model can improve capabilities, but it can also preserve old coverage mistakes or introduce new bottlenecks.

This matters particularly when the refresh introduces 6 GHz or Wi-Fi 7. Higher-frequency coverage behaves differently from 2.4 GHz, client support is uneven during transition periods, and a new AP may support uplink rates that are greater than the existing access switch port or cabling path. Power requirements can also change by model and feature set. The correct question is therefore not “Which Juniper AP replaces our existing unit?” but “What wireless experience does each space require, and which combination of AP, radio plan, Ethernet path, power source and Mist services delivers that experience with manageable risk?”

A refresh project should use the existing estate as evidence rather than as a fixed design template. Current AP positions reveal how the building was previously engineered, while monitoring data and help-desk history reveal where that design succeeds or struggles. User growth, floorplan changes, more video traffic, mobile scanning, guest access, IoT devices and modern security requirements can all justify changes in AP count or placement. A well-planned Juniper Access Point Refresh in Dubai uses these inputs to decide what should remain, what should change and what must be tested before the new wireless network becomes a production dependency.

Start with the business experience, not the AP model number

Understanding the Juniper Mist wireless architecture in a refresh project

Juniper access points are designed to operate with the Mist cloud platform. In practical terms, a refresh therefore needs a cloud-management plan as well as a physical replacement plan. The project should establish the organisation, sites, administrators, AP claiming process, WLAN configuration, device profiles, upgrade behaviour and the subscriptions or service entitlements required for the intended operational features. If the customer already uses Mist, the refresh may be an expansion or hardware-generation transition inside an existing operational framework. If Mist is new to the environment, onboarding and operational readiness become separate workstreams that must be completed before or alongside the first production migration.

Mist-managed APs send telemetry used for monitoring and troubleshooting, and the platform supports centralised configuration and lifecycle operations. This changes how a wireless team approaches validation. Instead of considering installation complete when an AP powers on and broadcasts an SSID, the team can define user-experience measures, observe connectivity behaviour and use collected data to investigate failures. However, the existence of cloud analytics does not remove the need for disciplined RF engineering. Telemetry can expose a poor physical design; it cannot make walls transparent, create missing Ethernet capacity or correct a badly chosen antenna pattern.

For multi-site organisations in Dubai and the wider UAE, the architecture can also support repeatable operational patterns, but templates should not override local site conditions. A standard corporate WLAN, authentication method and policy can be reused while AP type, count, mounting height and channel plan vary by building. The refresh design should deliberately separate what is globally standard from what must remain site-specific. That distinction is especially important for retail, hospitality, education, healthcare and mixed-use properties where physical conditions vary significantly even when the business policy is common.

Wi-Fi 6E or Wi-Fi 7: decide by requirement, not by generation label

Juniper’s current access point portfolio includes Wi-Fi 6E and Wi-Fi 7 models for different environments and performance levels. A refresh should not assume that the newest radio standard automatically belongs in every room. Wi-Fi 7 may be attractive for new high-density or performance-sensitive deployments, for estates with a long planned lifecycle, and where switching and cabling can support the chosen AP. Wi-Fi 6E can remain a valid fit where requirements are more moderate, where an organisation is standardising on an established model, or where client capability and budget do not justify a broader infrastructure change. The choice should be made per use case and then checked against the expected life of the deployment.

The most robust approach is to model the estate by space type. Standard office zones may use one AP class, high-density boardrooms or auditoriums another, rugged outdoor zones another, and hospitality-style wall-jack locations a purpose-built form factor. Juniper’s Wi-Fi 7 selection guidance itself emphasises environment, performance, antenna type and deployment location rather than choosing solely by peak data rate. That principle is especially useful in a refresh because it prevents an expensive single-model standard from being forced into spaces with very different RF and installation requirements.

Representative Juniper AP families to discuss during a refresh

Model availability and regional approval should be confirmed at quotation time, but the current Juniper portfolio illustrates why a refresh should be requirements-led. The examples below are not a substitute for an RF design and do not imply that every model is suitable for every UAE deployment.

Dubai and UAE 6 GHz planning: a regulatory and design checkpoint

The UAE has made spectrum in the 5925–6425 MHz range available for indoor Wi-Fi under defined regulatory conditions. That is relevant to Wi-Fi 6E and Wi-Fi 7 refresh discussions because 6 GHz capability is one of the principal reasons organisations consider newer access points. However, the existence of available spectrum should not be interpreted as permission to deploy any global radio configuration in any location. Equipment approval, operating mode, indoor or outdoor status, transmit-power limits and the specific regulatory domain applied to the access point must be validated for the intended deployment.

This is also a practical RF issue. A 6 GHz design is not simply a 5 GHz design with a new band enabled. Propagation and wall attenuation can influence cell size, while client support may vary considerably across corporate laptops, phones, scanners and IoT endpoints. If a business wants 6 GHz primarily to reduce congestion in dense indoor areas, the refresh should identify the actual percentage of compatible endpoints and decide how legacy clients will be served. In many deployments, 2.4 GHz and 5 GHz remain necessary even when 6 GHz is introduced.

For outdoor areas, semi-outdoor spaces, warehouses with open loading bays or unusual antenna requirements, regional compliance should be considered during design rather than after procurement. A candidate AP that is technically attractive on a global datasheet may need a different regional operating profile or may not suit the intended installation condition. FourTeck can include this validation in the pre-quotation scope so that model selection, radio design and physical placement are aligned before equipment is committed.

RF survey and design: the part of a refresh that protects the investment

A wireless refresh is an opportunity to correct assumptions inherited from an older deployment. Floorplans may have changed, walls may have been added, glass partitions may have become meeting rooms, workstations may be denser, and applications may now include continuous voice or video. Even when the existing AP count appears adequate, the original placement may have been optimised for a different Wi-Fi generation, different client radios or a different occupancy level. A predictive design can provide a starting point, while on-site measurements help validate attenuation, interference and practical mounting conditions.

The survey method should match the risk of the environment. A small branch with standard construction may need a lighter assessment than a hospital, hotel, warehouse, auditorium or multi-storey headquarters. High ceilings, metallic shelving, moving inventory, atriums, thick concrete, mirrored surfaces, external walls and neighbouring wireless networks can materially influence the design. In high-density areas, the engineering objective is often to control cell size and channel reuse rather than simply maximise transmit power. Excessive AP power can create sticky-client behaviour or unnecessary contention even when coverage looks strong on a heat map.

The refresh should also identify non-Wi-Fi interference and the role of dedicated scanning radios where supported by the selected Juniper AP. Continuous visibility can improve operations after installation, but design-time measurements remain valuable because they establish the physical baseline. A post-install validation survey is then used to confirm that the installed estate behaves as planned, not merely that every AP appears online.

A good RF deliverable therefore connects access point location to a reason: coverage target, capacity target, antenna behaviour, client requirement or construction constraint. That rationale is far more useful for future operations than a simple list of ceiling coordinates. It also helps when the organisation later renovates the space, adds high-density rooms or considers another AP generation, because the next engineer can understand why each location existed in the first place.

Switching, PoE and cabling readiness

Newer Juniper APs can expose limitations in the wired access layer. The refresh assessment should map each candidate AP model to the available Ethernet port capability and power budget at the corresponding switch. This is not a theoretical exercise: an access point may power on at a reduced condition, negotiate at a lower Ethernet rate than expected, or compete with phones, cameras and other PoE devices for a switch’s total power capacity. A wireless budget that excludes switching remediation can therefore underestimate the real cost of a successful refresh.

Mist subscriptions, licensing and operational entitlement

Hardware quantity is only one part of a Juniper Mist wireless quotation. The organisation should identify which cloud-managed capabilities are required and for what term. Existing customers may already have a subscription strategy, renewal date and standard entitlement. New customers need to align the refresh with account setup, subscription activation and operational ownership. Because product packaging and commercial terms can change, the final quotation should verify current Juniper part numbers and entitlement descriptions rather than relying on a historic bill of materials.

The important buyer decision is not simply whether a subscription is present, but which outcomes depend on it. Core wireless management, assurance, advanced location or other platform capabilities may be packaged separately depending on the current Juniper offer. If the business expects AI-assisted troubleshooting, experience metrics, location services or integrations, those expectations should be mapped to the exact entitlement during design. This avoids a common procurement problem in which AP hardware is correctly selected but the operating team later discovers that a desired function requires a service level that was not included.

Subscription term also affects lifecycle planning. A three-year hardware strategy paired with a one-year cloud term can create annual renewal administration, while a longer term can align expenditure and operational continuity but reduces flexibility if the organisation expects a major architecture change. There is no universal correct term. Procurement, finance and the network team should choose based on budget structure, deployment lifetime and renewal governance.

For an existing Mist estate, the refresh should additionally check whether old AP subscriptions can be reassigned, whether new APs require new entitlement, and how the migration timing intersects with renewal. These are commercial and platform questions that should be confirmed with the current Juniper ordering rules. FourTeck can structure the quotation around the required service period and identify where final confirmation from distribution or manufacturer channels is necessary.

Client inventory: the fastest way to separate useful upgrades from expensive overdesign

An enterprise wireless network serves clients, so a refresh should include at least a practical client inventory. The objective is not to document every serial number. It is to understand the mix of radios and behaviours that drive design: corporate laptops, mobile phones, voice handsets, barcode scanners, printers, cameras, guest devices, IoT equipment and any specialised operational terminals. The same AP estate can perform very differently when the client population shifts from mostly modern laptops to a mixture that includes older 2.4 GHz-only devices or roaming-sensitive handhelds.

For Wi-Fi 6E and Wi-Fi 7 planning, the percentage of 6 GHz-capable endpoints is especially useful. If almost no production clients can use 6 GHz today, the business case may rest on lifecycle and expected refresh cycles rather than immediate throughput improvement. If a large fleet of compatible laptops is already deployed, 6 GHz can become a near-term capacity tool. Similar reasoning applies to Wi-Fi 7 features: endpoint support and application demand determine how much of the AP’s advanced capability is realised in daily use.

Client behaviour also matters for authentication and roaming. Some legacy or embedded endpoints may support limited security methods, have older drivers or react poorly to aggressive band-steering and roaming assumptions. A pilot should include these difficult clients deliberately. A refresh that works perfectly for the IT team’s newest laptops but fails on warehouse scanners or clinical devices has not met the business requirement. The client inventory is therefore both a design input and a migration test plan.

Authentication, segmentation and security should be reviewed during the refresh

Wireless replacement is a natural point to review how users and devices join the network. Some organisations still carry legacy SSIDs, shared keys, broad VLANs or duplicated guest networks that were created years earlier for temporary requirements. Moving them unchanged to new hardware can preserve unnecessary risk and operational complexity. The refresh does not have to become a full identity transformation project, but it should identify which WLANs are still needed, which authentication methods remain acceptable, which device groups require segmentation and which policies can be simplified.

Enterprise authentication may depend on RADIUS, certificates, identity platforms, directory services or network access control. Guest access can involve portals, sponsorship or Internet-only segmentation. IoT devices may require a different onboarding model from managed laptops. Each dependency should be included in the migration test plan because a radio can appear healthy while users still fail to obtain network access after association. DHCP scope sizing, DNS, VLAN trunking and firewall policy are common examples of upstream elements that influence whether a refresh is perceived as successful.

Security policy should also account for the capabilities of the client fleet. Enabling a modern security mode everywhere may be desirable but can strand older devices. Maintaining a legacy SSID indefinitely creates its own risk. A practical approach is to identify exceptions, isolate them where appropriate, create a retirement plan and avoid letting the oldest endpoint define the security posture of the entire wireless estate.

The resulting design should clearly separate the AP refresh from optional adjacent projects. If a customer wants only hardware replacement, the quotation can preserve the existing authentication architecture while highlighting risks. If the business wants to modernise identity and segmentation at the same time, those changes should be scoped explicitly because they add testing, coordination and rollback requirements beyond the physical AP migration.

A practical refresh workflow for a Dubai business

Migration coexistence: old and new APs can affect each other

Many enterprise refreshes cannot replace every access point in one maintenance window. Buildings are migrated floor by floor, branches are scheduled over weeks, or equipment is replaced when local access is available. During this period, old and new wireless generations may share the same RF environment. That coexistence needs planning. If both estates broadcast the same SSIDs, clients may roam between them. Differences in radio capability, channel width, transmit power, security support or feature configuration can create user behaviour that will not exist in the final state.

The migration sequence should therefore consider physical adjacency. Replacing an isolated test area is useful for functional validation, but it may not reveal roaming behaviour at the boundary between generations. A floor-level or zone-level wave can provide a more realistic test while still preserving rollback. In dense offices, the team should also prevent temporary overpopulation of channels if old APs remain active beside new ones. Simply adding the new AP before switching off the old unit can increase contention during the change window.

Operational ownership is equally important. The help desk should know which areas are migrated, which AP platform is authoritative for each floor, and how to distinguish a migration-related issue from an unrelated endpoint or application problem. Change records should include old AP identity, new AP identity, switch port, physical location and the date of replacement. These records become valuable if a user complaint appears days later.

For large estates, a temporary coexistence policy can define acceptable mixed operation, the maximum duration of each wave and what must be completed before the next phase begins. This turns a long refresh into a controlled programme instead of a sequence of disconnected installation visits.

Use cases where refresh design usually needs extra care

When a smaller AP can be the better design choice

Refresh projects sometimes become technology showcases in which the highest-specification AP is proposed across the entire estate. That approach can simplify the bill of materials, but it is not automatically the best engineering or financial decision. A standard office with moderate client density, conventional applications and limited 6 GHz endpoint adoption may not benefit meaningfully from the same radio capacity used in an auditorium or high-density collaboration area. If the lower-tier AP still meets lifecycle, security, management and performance requirements, it can provide a more efficient refresh.

The trade-off is standardisation. Using several AP models requires operations teams to understand more hardware variants, maintain different spares and track model-specific power or mounting requirements. For smaller estates, one mainstream model may therefore be sensible even if some locations do not use its full capability. For larger sites, a two- or three-class design can produce better economics while preserving standardisation at the level of space type.

The key is to make the choice explicit. If a premium AP is selected everywhere, the quotation should explain the operational or lifecycle reason. If a lower-cost option is used in standard areas, the design should document the capacity assumptions that make it suitable. This prevents procurement from reducing the bill by substituting models without understanding the RF and uplink consequences, and it prevents engineering from oversizing the estate without demonstrating buyer value.

When a higher-capacity or different-form-factor AP should be evaluated

A larger AP class becomes relevant when the environment genuinely creates more radio demand or needs features unavailable on an entry model. Examples include high simultaneous client counts, demanding channel plans, locations where radio flexibility matters, or spaces expected to remain unchanged through several endpoint refresh cycles. The decision should also consider whether the access switch can provide the required multigigabit Ethernet and PoE. Buying a stronger AP without supporting its wired dependencies can shift the bottleneck rather than remove it.

Form factor can be even more important than raw capacity. A ruggedised indoor/outdoor AP may be necessary for exposed locations. External or directional antenna options can be appropriate where the RF shape must be controlled. Wall-jack or desktop models can make sense in room-based deployments that also need local Ethernet connectivity. Using a ceiling AP simply because it is the corporate standard can make installation awkward or produce an inferior RF outcome in these spaces.

A refresh design should therefore include exceptions as a normal part of architecture, not as procurement complications to eliminate at all costs. Standardise where the environmental assumptions are common and choose a different model where the building or use case demands it. Juniper’s portfolio provides multiple Wi-Fi generations and deployment types precisely because one access point cannot be optimal everywhere.

Installation planning: physical details that commonly affect schedule

The installation phase can become the longest part of a refresh if physical assumptions are not checked early. Ceiling type, mounting bracket, access permissions, working-at-height requirements, occupied hours, cable identification, switch-room access and site security can all affect how quickly a nominally simple AP replacement can be completed. A branch with ten visible ceiling APs may be straightforward; a hotel with hundreds of room units or a warehouse with high-bay mounting is a different operational project.

Pilot design and acceptance testing

A pilot is most useful when it tests the assumptions that could invalidate the refresh, not when it simply proves that a new AP can connect to the Internet. Select a representative area with realistic users, switch infrastructure and physical construction. If the estate includes unusual clients, include them. If the design depends on 6 GHz, use compatible endpoints and verify how non-6 GHz devices behave. If a multigigabit uplink is part of the plan, confirm actual negotiation and switch configuration. If roaming quality is a business requirement, walk the relevant path while using the application that matters.

Acceptance criteria should be written before the pilot so the project does not move the goalposts after installation. Useful criteria can include successful authentication, IP assignment, DNS resolution, access to corporate applications, guest isolation, expected SSID availability, stable roaming, absence of critical coverage gaps, AP cloud connectivity, correct switch speed and PoE state, and visibility in the Mist platform. The exact performance threshold should reflect the business application and client capability rather than an arbitrary speed-test number.

The pilot is also the right stage to validate operational processes. Can the network team locate a client problem in Mist? Are administrators assigned correctly? Is firmware behaviour understood? Are alerts useful? Does the service desk know what information to collect from a user? A technically successful deployment can still create operational frustration if the support model is not prepared.

Once the pilot passes, capture the approved configuration and installation method as the standard for subsequent waves. Where site conditions differ, record the exceptions. This reduces variation without pretending every branch or floor is identical.

Post-refresh operations: make the new estate easier to support than the old one

A modern AP estate should reduce operational ambiguity. That requires consistent naming, site assignment, floorplan placement, switch-port records and configuration ownership. If the old environment suffered from unknown AP locations, undocumented manual changes or inconsistent SSIDs, the refresh is an opportunity to correct those weaknesses. Device naming should be meaningful enough for a support engineer to connect a cloud event to a physical location without searching through installation spreadsheets.

Firmware policy deserves explicit treatment. Juniper Mist supports AP upgrade operations, but the business should decide how recommended versions, maintenance windows and staged upgrades are handled. Critical sites may use a pilot group before wider rollout. The objective is to keep the estate current without creating unnecessary simultaneous change. Change control should also define who is permitted to alter WLANs, AP profiles and radio settings.

Monitoring should focus on user experience rather than counting online devices. An AP can be reachable while clients fail authentication or experience poor roaming. Service-level indicators, client events and telemetry are most useful when tied to business locations and known applications. The operations team should establish a small set of recurring checks after cutover and review whether the refresh actually reduced the incidents that justified the project.

Finally, keep an accurate spare strategy. A large estate may justify one or more spare units by model class, but spares must remain compatible with the management and subscription process. The replacement procedure should be documented so an outage does not become the first time the team discovers how to claim, assign and configure a spare AP.

Common refresh mistakes and the buyer risk behind each one

How to build an accurate Juniper Access Point Refresh quotation

Wireless refresh quotes vary widely because different suppliers may include different assumptions. One proposal may contain AP hardware only, another may include subscriptions, mounting kits and installation, while another may add surveys, switch remediation and migration services. Buyers should compare scope before comparing totals. An accurate quotation begins with enough discovery to separate confirmed requirements from allowances.

At minimum, the quote should identify the AP models or model classes, quantities, required brackets or accessories, applicable Mist subscriptions and term, installation scope, survey scope if included, configuration and migration services, post-install testing, support assumptions and exclusions. If switch upgrades or cabling changes are likely but not yet surveyed, the quote should state whether they are excluded, estimated or priced as optional items. This prevents a low initial figure from becoming a larger project through change requests.

The quotation should also make regional and availability assumptions visible. Current orderability, lead time, local regulatory approval and exact part numbers must be reconfirmed when the buyer is ready to purchase. This is particularly important on projects planned over several months, because product portfolios and commercial packaging can evolve during the design period.

For multi-site estates, a phased bill of materials can help finance and operations. Separate the pilot, first production wave and later branches if the organisation wants to validate the architecture before committing every site. The trade-off is that later pricing or availability can change. A single procurement can lock the design and commercial basis earlier but requires greater confidence in quantities. The right structure depends on project risk, deployment schedule and purchasing policy.

What information should be captured from the existing Wi-Fi estate?

The more accurate the current-state record, the fewer assumptions the refresh needs. The goal is not paperwork for its own sake. Each item should help answer a design, migration or quotation question.

Refresh planning for organisations already using Juniper Mist

An existing Mist customer has an advantage: the current platform can provide operational evidence for the refresh. Site configuration, AP status, client experience and event history can help identify where problems are structural versus transient. The project should review the quality of the existing organisation and site structure before adding new hardware. If sites are inconsistently named, AP profiles have drifted or old SSIDs remain active, a hardware refresh can be paired with controlled configuration cleanup.

The team should also decide whether the new generation will inherit existing configuration exactly or use a revised baseline. Exact inheritance minimises change but can preserve outdated settings. A revised baseline improves consistency but increases the number of variables changed during migration. For large estates, a staged approach works well: create the approved target profile, validate it in a pilot site, and then migrate site groups while tracking exceptions.

Existing subscriptions and renewal dates should be reviewed early. Depending on current commercial rules, a hardware replacement can have entitlement implications. Do not assume that an AP swap is administratively identical to replacing a like-for-like device under the same service. The final bill of materials should be reconciled against the customer’s current Juniper account and active terms.

Operationally, the migration should preserve useful historical context where practical. Even when a new AP receives a new hardware identity, maintaining consistent site and location naming helps engineers compare before-and-after behaviour. The purpose of a refresh is not only to install new radios; it is to create a wireless estate that is easier to understand and improve over the next lifecycle.

Refresh planning for organisations moving to Mist for the first time

When the existing Wi-Fi uses another management architecture, the project includes a platform transition as well as an AP refresh. This adds design questions around account ownership, administrator access, site hierarchy, configuration templates, authentication integration, firewall egress to cloud services and the operating procedures used after cutover. These elements should be established before the first large migration wave so installation teams are not making governance decisions under time pressure.

Configuration should be translated by intent rather than copied field by field from the old controller. A legacy WLAN may have settings that are specific to the previous vendor or were added to work around an old client problem. The design team should identify what business outcome each setting was meant to achieve and then implement the equivalent policy using the new architecture. This can simplify the target environment and avoid carrying years of accumulated exceptions into Mist.

Training and support readiness deserve budget and schedule. Network engineers need to understand the Mist workflow for onboarding, site assignment, WLAN changes, client troubleshooting, firmware management and escalation. The service desk does not need deep platform expertise, but it should know what information to gather and where to route incidents. Clear role-based administrator access is preferable to a shared high-privilege account.

The pilot should therefore test both technology and operating process. If a user cannot connect, the team should be able to diagnose the path using the new tools. If the organisation can install APs but cannot confidently support them, the migration is not yet ready for scale.

Frequently asked buyer questions

Support, lifecycle and spares after the refresh

The best refresh design considers the next failure before the first production AP is installed. Support coverage, replacement process and spare availability should be aligned with business criticality. A small office that can tolerate limited disruption may rely primarily on vendor or supplier replacement, while a large hospitality property, hospital or logistics operation may justify local spare hardware for critical areas. Spare strategy should reflect the number of models in the design; excessive model variation can make it expensive to hold useful inventory.

Lifecycle planning also means preserving documentation. Record the approved AP model by space type, mounting method, switch requirement, subscription term and reasons for any exceptions. When the organisation adds a new floor two years later, these records help determine whether to extend the existing standard or reassess based on newer hardware. Without documentation, every expansion becomes a new design exercise and increases configuration drift.

Firmware lifecycle should be governed centrally. The team should know how recommended versions are evaluated, how test groups are used, when production upgrades occur and what rollback or escalation path exists. The same applies to configuration changes. A refresh provides value when it reduces unmanaged variation and makes the estate predictable.

Finally, review the project outcomes after several weeks of normal business use. Compare incident volume, user feedback, service metrics and problem locations with the baseline captured before migration. If the refresh was justified by recurring meeting-room complaints, roaming failures or branch support workload, the post-project review should show whether those problems improved. This closes the loop between infrastructure spend and business outcome.

What FourTeck needs from the buyer for an accurate refresh discussion

You do not need a perfect design before requesting a quotation. The following inputs allow the initial assessment to separate known requirements from items that need survey or confirmation.

Plan the Juniper refresh around your building, clients and wired network

A Juniper Access Point Refresh in Dubai can be a straightforward lifecycle replacement or a broader wireless redesign. The right scope depends on the problems you are trying to solve, the physical environment, endpoint mix, Mist operating model, switching and PoE readiness, 6 GHz strategy and the amount of migration change your business can absorb. FourTeck can help turn those inputs into a practical assessment, candidate AP design and quotation scope without assuming that every old AP position or every newest model is automatically correct.
