Direct answer for buyers
The Ubiquiti NanoBridge M5 22, model NB-5G22, is an outdoor 5 GHz MIMO radio with an integrated 22 dBi dish. It was built for directional links such as building-to-building connections, remote customer endpoints and network extensions where a clear radio path is available. It is most relevant when maintaining an existing airMAX M installation or when a matching legacy endpoint is specifically required. Before proceeding, a buyer should confirm regional frequency rules, firmware interoperability, passive 24 V PoE, Ethernet speed, mounting condition, line-of-sight quality and whether a newer airMAX platform would be a more supportable choice.
What it does
The unit concentrates radio energy in a narrow direction instead of spreading coverage around a site like a conventional indoor access point. That makes it useful for a planned outdoor path between two known locations. The radio and feed are integrated into the antenna assembly, reducing feeder-cable loss and simplifying the outdoor installation compared with a separate radio and antenna arrangement.
In a typical design, one unit communicates with another compatible airMAX radio across a clear path. The Ethernet connection carries network traffic and passive PoE power from the indoor adapter to the outdoor device.
Who should consider it
Organisations with an existing NanoBridge M5 link may consider the NB-5G22 when a matched replacement is required and compatibility has been checked. It may also be relevant to maintenance contractors, wireless internet operators, CCTV integrators and businesses connecting a detached office, guardhouse, warehouse or remote network cabinet.
A new deployment should compare this legacy platform with current Ubiquiti bridge options. Modern alternatives can offer faster Ethernet, newer radio technology, easier lifecycle planning or improved interference handling, depending on the selected model.
Business challenges this product may address
Connecting separate buildings
A directional bridge can extend an Ethernet network across a yard, road or open site where installing fibre is difficult, disruptive or uneconomical. The path still requires proper survey and line-of-sight validation.
Maintaining a legacy endpoint
A matching radio may reduce migration work when one side of an older airMAX M link has failed. Firmware, regional version and configuration compatibility must be reviewed rather than assumed.
Reaching remote equipment
The link can carry network access toward cameras, telemetry, access-control equipment or a small remote LAN, subject to bandwidth, power, switching and environmental requirements.
Avoiding antenna cable loss
The integrated feed and radio design removes the need for a long RF feeder cable. Outdoor Ethernet still needs suitable shielding, grounding and surge-protection planning.

Compatibility and dependency notice
The NB-5G22 is not a plug-and-play substitute for every current Ubiquiti 5 GHz bridge. Existing airMAX M networks may use channel widths, security settings, firmware versions and proprietary polling configurations that must be reproduced carefully. A current airMAX AC radio may require a migration plan rather than a direct mixed-generation assumption. Regional versions can also expose different frequencies and output limits. Confirm the far-end model, firmware, country code, Ethernet design, passive PoE wiring and mounting arrangement before purchasing.
The 10/100 Ethernet interface creates a practical ceiling that matters when the link is expected to transport modern high-bandwidth applications. Where future growth, higher camera counts, large file transfers or faster internet services are anticipated, a newer platform may be more appropriate even if the legacy unit can technically form the link.
A practical purchase and deployment journey
Identify the reason for choosing NB-5G22
Decide whether the requirement is a failed-unit replacement, an additional compatible endpoint, a spare for an installed estate or a completely new bridge. The answer changes the recommendation.
Review the radio path
Measure distance, mounting heights and obstructions. Verify visual line of sight and Fresnel-zone clearance, then account for interference, rainfall margin, mast movement and nearby reflective structures.
Confirm the complete bill of materials
Include the radio, dish, feed, pole hardware, passive PoE injector, power lead, outdoor shielded cable, surge protection, grounding and any enclosure, switch or UPS components needed at each end.
Configure, align and validate
Set the permitted country profile, channel, width, security and airMAX parameters. Align both ends using signal measurements, then test packet loss, latency and usable application throughput under load.
Document and plan lifecycle
Record IP addresses, credentials, firmware, channel plan, mounting photographs and spare strategy. For a legacy platform, establish the trigger and budget for migration to a current bridge family.
Directional gain and link planning
A 22 dBi dish focuses the link and can improve received signal compared with a low-gain omnidirectional device, but gain does not remove the need for a clear path. Trees, roofs, cranes, vehicles and terrain can obstruct the direct path or part of the Fresnel zone. The narrow coverage also makes physical alignment important.
A link budget should consider transmit power allowed in the country, antenna gain, distance loss, cable and connector loss, receiver sensitivity, interference and a fade margin. Maximum-distance marketing figures are not a substitute for site-specific engineering.
airMAX M operation and coexistence
The NanoBridge M generation uses Ubiquiti’s airMAX approach to coordinate wireless access more predictably than basic contention in suitable deployments. The operational benefit depends on how the access point and stations are configured, the number of endpoints, signal quality and channel conditions.
For an existing network, copy settings only after documenting the original system. For a new mixed estate, verify interoperability rather than assuming every Ubiquiti radio generation will operate with every airMAX mode and firmware combination.
Outdoor reliability depends on installation
The outdoor enclosure and broad historical operating-temperature rating support field installation, but reliability also depends on the quality of the mast, clamps, cable route, drip loops, grounding, surge protection and indoor power environment. Passive PoE must be connected correctly because it is not the same as universal standards-based PoE negotiation.
Dubai heat, dust and exposed rooftops make mechanical security and cable protection especially important. Inspection access should be planned so that alignment and connectors can be checked without unsafe work.
Ideal environments and use cases
Warehouse compounds
Link a detached warehouse, gate office or service building where trenching fibre is impractical and a clear path exists.
Legacy wireless ISP sites
Maintain a compatible customer endpoint while planning a controlled migration to a current platform.
Remote surveillance points
Carry camera traffic where bitrate, latency and availability requirements fit the link and power design.
Temporary project connectivity
Support a planned temporary link when equipment condition, spectrum rules and removal arrangements are understood.
The model is less suitable where there is no clear line of sight, where Gigabit-class application throughput is required, where a fully supported current-generation platform is mandatory, or where the buyer expects cellular connectivity from the “5G” wording.
Operational and integration considerations
Treat the bridge as part of the wider network rather than as an isolated antenna. Decide whether it should transport untagged traffic, VLAN trunks, management access, CCTV networks or multiple services. Confirm the switch port configuration at both ends and protect management access with appropriate credentials and network controls. Legacy firmware should be reviewed for operational risk and compatibility before exposure to untrusted networks.
Capacity planning should use real application traffic. A dozen cameras, voice endpoints and business internet users can create a different load profile from a single remote workstation. Measure peak and sustained bitrate, packet-size behaviour and latency sensitivity. The Fast Ethernet port means that application planning should remain realistic even when radio conditions are excellent.
Resilience is another design choice. A single wireless path, single injector and single mains circuit create several points of failure. Businesses requiring higher continuity may need UPS power, spare injectors, alternate routing, redundant links or a wired fallback. These items are not automatically included with the radio and should be added to the project scope when required.
Questions to resolve before ordering
A replacement may prioritise compatibility; a new design should prioritise lifecycle, capacity and current platform choices.
Provide the exact model, firmware version and configuration mode so interoperability can be checked.
Share expected internet speed, user count, camera bitrate, VLANs and latency-sensitive applications.
Distance, rooftop height and visible obstructions should be documented before equipment selection.
Frequency availability and output limits vary. Confirm destination and lawful operating parameters.
Clarify supply only, preconfiguration, survey, mounting, alignment, testing, documentation and ongoing support.

UAE availability and support guidance
Contact FourTeck to confirm current UAE availability. Because the NB-5G22 is a legacy model, supply may depend on regional version, quantity, vendor channel, remaining inventory or sourced product condition. A quotation should state the exact part, included components and any applicable warranty guidance rather than relying on the family name alone.
Delivery and project coordination can be discussed after the requirement is confirmed. Installation and configuration should be included explicitly when needed, especially for rooftop work, mast mounting, alignment, cable routing and acceptance testing.
Use the FourTeck Dubai contact page to share the link details and requested timeline.
Dubai, Abu Dhabi, Sharjah and Ajman coverage
FourTeck can coordinate requirement review and quotation discussions for organisations in Dubai, Abu Dhabi, Sharjah and Ajman. The appropriate process depends on whether the request is a unit-only purchase, a replacement investigation or a surveyed wireless-link project. For installation work, share the building type, roof-access conditions, mast details, cabling route, safety requirements and site-contact information. Site visits, delivery timing and configuration scope remain subject to confirmation in the quotation.
GCC Availability
FourTeck can assist businesses across the GCC with requirement review for legacy Ubiquiti NanoBridge equipment and suitable current alternatives. Support may include identifying the exact regional model, checking the intended endpoint, discussing link distance and capacity, preparing quotation options, and defining whether configuration or installation coordination is required. Requests from the United Arab Emirates, Saudi Arabia, Kuwait, Qatar, Bahrain and Oman should include the destination country because permitted frequencies, regional variants, procurement arrangements and service logistics can differ. Product availability, delivery schedules, site visits and vendor lead times vary according to country, quantity, equipment condition and project scope. Share the exact model, quantity, intended use, deployment location, preferred schedule and any migration requirement so that FourTeck can provide relevant guidance. For Kuwait-related coordination, buyers may also review FourTeck Kuwait resources.
Africa Availability
Organisations planning wireless links in African markets can contact FourTeck for product evaluation, legacy replacement guidance, alternative-model comparison, accessories, power requirements, deployment planning and quotation coordination. Availability for the NB-5G22 may depend on destination, regional radio version, product condition, quantity, shipping arrangement and vendor lead time. Outdoor deployment also needs attention to local spectrum rules, power stability, lightning exposure, mast design and access to qualified installers. Buyers should provide the destination country, exact requirement, number of links, far-end equipment, expected throughput and desired deployment schedule. Installation or support coverage should be confirmed for each project rather than assumed. Regional information is available through FourTeck Africa, with additional resources for Kenya technology projects and Uganda business technology requirements.

Why businesses contact FourTeck
A legacy wireless product request often involves more than locating a part number. The buyer may need to know whether a matching unit will interoperate, whether the available package includes all mechanical and power components, or whether migration will be less risky than extending the old platform. FourTeck can help turn those questions into a defined bill of materials and service scope.
The discussion can cover compatibility review, alternative selection, quotation coordination, installation planning, configuration, testing and documentation. Recommendations depend on the supplied project facts, and no performance, availability or installation outcome should be assumed until the path and scope are reviewed.

Frequently asked questions
Is the NB-5G22 a cellular 5G product?
No. It is a 5 GHz outdoor wireless bridge from the airMAX M generation. It does not provide SIM-based cellular 5G service.
What is the antenna gain?
The NB-5G22 uses an integrated 22 dBi directional dish. Alignment and path clearance remain essential despite the antenna gain.
Can it connect two buildings?
It can be used in a point-to-point design when a compatible radio is installed at the other end and the path, spectrum, capacity and mounting conditions are suitable.
Does it use standard PoE?
Historical documentation specifies 24 V passive PoE. Confirm injector voltage and pinout before connection; passive PoE should not be treated as universal standards-based PoE.
Will it work with a newer airMAX AC radio?
Compatibility depends on models, modes and firmware. A mixed-generation link should be checked specifically, and a planned migration may be preferable.
What throughput should be expected?
Ubiquiti historically positioned the NanoBridge M family for 100+ Mbps real outdoor throughput, but actual usable capacity depends on signal, channel width, interference, distance and configuration. The Ethernet port is 10/100 Mbps.
Is the NB-5G22 still the right choice for a new link?
It may be appropriate for a compatibility-driven legacy requirement. A new long-term deployment should compare current Ubiquiti bridge models for lifecycle, capacity and management benefits.
