Licensed 11 GHz point-to-point infrastructure
Ubiquiti airFiber 11 Low-Band Complete AF11-Complete-LB in Dubai, UAE
A complete low-band airFiber endpoint package for organisations designing licensed-frequency backhaul links where predictable spectrum planning, full-duplex operation and long-distance connectivity matter more than consumer-style wireless convenience.
Plan the link before ordering
Confirm licensed frequencies, endpoint quantities, path profile, duplexer requirements and installation scope.
Direct answer for buyers
The AF11-Complete-LB is one endpoint of a licensed 11 GHz point-to-point wireless bridge. It is mainly used to carry network traffic between towers, buildings, campuses or remote operational sites where a dedicated microwave path is preferred. It should be considered by service providers, enterprises, utilities, public-sector networks and industrial operators that can obtain the appropriate spectrum approval and provide clear line of sight. Before proceeding, the buyer should verify the assigned transmit and receive frequencies, determine whether SISO or MIMO is required, confirm that two complete endpoints are included in the project quantity, and commission a path study covering distance, Fresnel clearance, rain fade, mounting strength, grounding and local regulatory requirements.
What the complete low-band kit does
The package combines the airFiber 11 radio, the AF-11G35 directional antenna and one low-band duplexer. Together, these components form a tightly focused outdoor wireless endpoint designed for frequency-division duplex operation in the licensed 11 GHz range. A working point-to-point link normally requires a correctly matched endpoint at each side, with transmit and receive frequencies coordinated so the two radios communicate without overlap.
Unlike an indoor access point, this product is not intended to provide Wi-Fi to laptops or phones. Its role is transport: it moves Ethernet traffic across a directional microwave path. Typical traffic can include internet transit, branch connectivity, CCTV backhaul, operational technology data, voice services, cloud access and other IP applications, subject to the capacity and design of the finished link.
Who should evaluate it
The AF11-Complete-LB suits buyers who need more control over radio planning than a shared unlicensed band can offer. It may fit wireless internet providers extending tower capacity, enterprises linking separate facilities, logistics or industrial operators connecting yards and plants, hospitality groups joining buildings, and public-sector organisations creating resilient site-to-site paths.
It is less suitable where spectrum licensing is unavailable, line of sight is blocked, mounting structures cannot safely carry the antenna, or the organisation needs a simple plug-and-play connection without professional alignment. Buyers should also avoid choosing the low-band version solely because it is available; the duplexer band must match the approved frequency plan for that particular link.
Business challenges the AF11-Complete-LB can address
Fibre delay between sites
A licensed microwave link can provide an alternative transport path when civil works, landlord permissions or carrier lead times make fibre difficult. The business case should still compare capacity, lifecycle cost, licence fees and maintenance.
Congested unlicensed spectrum
Moving a backbone path into coordinated licensed spectrum can reduce exposure to uncontrolled neighbouring networks. Actual link quality remains dependent on correct frequency coordination, antenna alignment and RF engineering.
Remote operational connectivity
Directional backhaul can connect sites such as depots, compounds, utilities, towers or production areas where trenching is impractical. Power, grounding, tower access and environmental exposure must be part of the design.
Path diversity
The radio may form a secondary route alongside fibre or another wireless system. Resilience depends on network topology, independent failure domains, routing design and power backup rather than the radio alone.
Core platform capabilities
Full-duplex architecture
The platform uses separate transmit and receive frequencies, allowing simultaneous bidirectional communication when the spectrum plan and duplexers are correctly selected.
SISO or MIMO options
One low-band duplexer is included for SISO operation. A second compatible low-band duplexer is required for MIMO, and both ends must be engineered consistently.
Directional antenna system
The AF-11G35 dish concentrates energy into a narrow path, supporting long-distance designs while demanding accurate alignment and suitable mounting structures.
Outdoor deployment
The radio and antenna are built for outdoor infrastructure roles, but weatherproofing, grounding, surge protection and safe tower work remain installer responsibilities.

Frequency, licensing and configuration dependencies
The “Low-Band” designation is a purchasing and engineering detail, not a general statement that the radio can use any lower 11 GHz channel. The duplexer filters transmit and receive frequencies into defined ranges. The approved frequency pair must be checked against the duplexer arrangement at both ends before equipment is ordered. A mismatched high-band and low-band plan can prevent the link from operating correctly even when the radio and antenna model appear otherwise suitable.
Spectrum licensing is handled under the rules of the destination country. In the UAE, the buyer or appointed project consultant should establish the applicable regulatory process, permitted channel plan, EIRP limits and documentation requirements. FourTeck can assist with equipment selection and quotation coordination, but a product purchase should not be treated as automatic permission to transmit.
The supplied single low-band duplexer supports a SISO arrangement. Buyers seeking the platform’s higher MIMO capacity should confirm the correct additional AF-11-DUP-L component, installation method and matching configuration at both endpoints. Channel width, modulation, link budget and expected availability target should be agreed during design rather than assumed from the maximum product rating.
A practical purchase and deployment journey
Define the service requirement
Document the sites, traffic profile, target capacity, availability expectation, growth horizon and whether the link is primary, secondary or temporary infrastructure.
Complete the path assessment
Confirm coordinates, path length, elevation profile, Fresnel clearance, obstruction risks, tower height, structural capacity and expected rain attenuation.
Coordinate spectrum and duplexers
Use the approved channel pair to select low-band or high-band arrangements. Verify which endpoint transmits high and which transmits low, and determine whether SISO or MIMO is required.
Build the complete bill of materials
Include two endpoints, any additional duplexers, shielded outdoor cabling, surge protection, grounding materials, mounting hardware, power backup, spares and required network equipment.
Install, align and commission
Use competent tower and RF technicians. Record alignment, signal levels, modulation, capacity, error rates, grounding, configuration backups and handover information.
Capacity is a link-design outcome
The published 1.2+ Gbps figure describes the upper capability of the platform under supported conditions, not a guaranteed application throughput for every path. Channel width, MIMO configuration, modulation, signal-to-noise ratio, environmental fading and Ethernet overhead all influence the result. A buyer should specify minimum usable capacity and expected availability rather than simply requesting the maximum advertised number.
For business-critical traffic, the design should also consider packet size, latency sensitivity, quality-of-service policies and traffic bursts. CCTV aggregation, voice, cloud applications and bulk backup each create different patterns. Testing should therefore include realistic traffic or an agreed acceptance method, not only a basic radio signal reading.
Licensed spectrum improves control, not certainty
A coordinated channel can reduce uncontrolled interference compared with crowded public bands, but it does not eliminate every operational risk. Poor alignment, connector issues, water ingress, tower movement, inadequate grounding, power instability and an undersized fade margin can still affect performance. Link health should be monitored and maintenance access planned from the beginning.
The licensing process can also affect procurement timing. Frequency assignments, country rules and supporting documents may determine whether low-band equipment is appropriate. Ordering the radios before the spectrum plan is settled can create avoidable rework, particularly where duplexer frequencies do not match the final authorisation.
Operational management and support
The radio includes separate data and management interfaces, enabling administrators to keep operational access distinct from the primary traffic path where the surrounding network is designed accordingly. Management security should include controlled addressing, restricted administrative access, strong credentials, configuration backups and a documented firmware policy.
Support planning should identify who monitors the link, who can access the tower, what spares are held, how configuration changes are approved and what escalation route applies after a fault. A microwave link can be highly useful infrastructure, but it should be operated with the same discipline as switching, routing, power and fibre assets.
Ideal environments and use cases
WISP tower backhaul
Transport aggregated subscriber traffic between a distribution tower and a core location, subject to capacity planning and licensed channel availability.
Campus building links
Connect separated buildings where trenching fibre is constrained and rooftop or tower line of sight can be established safely.
Industrial and utility sites
Carry operational, security and business traffic between remote facilities while accounting for harsh access conditions and power resilience.
Fibre route diversity
Create an alternate physical medium for selected services, provided routing and power are designed to avoid shared failure points.
CCTV aggregation
Backhaul multiple high-resolution camera streams from remote compounds after validating sustained bitrate, retention architecture and QoS.
Temporary project connectivity
Support long-duration construction or remote projects where a reusable licensed link is commercially justified and regulatory timing fits the project.
Integration and operational considerations
Ethernet design
The Gigabit Ethernet data interface should connect to switching or routing equipment sized for the expected traffic. Network architects should decide whether the link carries a routed subnet, VLAN trunk, provider transport or another service model. Loop prevention, MTU, QoS, multicast handling and failover behaviour should be tested with the wider network.
Power and protection
Use the included power method only within the manufacturer’s supported voltage range and follow polarity guidance for terminal-block installations. Outdoor Ethernet, surge protection, grounding and bonding should be designed for the site. UPS or DC plant capacity should reflect radio load, upstream network devices and the required runtime during outages.
Structures and alignment
The 35 dBi dish has a narrow beam, so stable mounting and precise alignment are essential. Pole diameter, tower load, wind exposure, sway, safe climbing access and future maintenance all require review. A visually clear path is not enough; the Fresnel zone and earth curvature become increasingly important as distance grows.
Security and administration
The radio’s AES capability protects the wireless transport at the platform level, but the end-to-end security design may still require VPNs, firewall controls, segmentation and application encryption. Administrative interfaces should not be openly reachable from untrusted networks. Configuration documentation and access ownership should be included in handover.

How FourTeck can assist
FourTeck can review the equipment requirement before a quotation is prepared, helping the buyer distinguish the radio endpoint, antenna, duplexer arrangement and supporting installation materials. This is particularly important with the AF11-Complete-LB because the frequency plan determines whether the low-band configuration is appropriate. Requirement review can also identify whether the requested quantity represents one endpoint or a complete two-site link.
For project discussions, share site coordinates, path length, intended traffic, target capacity, licence status, proposed mounting locations and whether installation is required. FourTeck can then coordinate a product quotation, confirm current UAE availability and discuss related network equipment or professional services. Visit the FourTeck technology products section, review available installation and configuration services, or contact the Dubai team with the project details.
UAE availability and support guidance
Contact FourTeck to confirm current UAE availability for the AF11-Complete-LB, the quantity needed and any matching duplexers or supporting equipment. Availability can depend on regional model, vendor lead time, order size and the final licensed-frequency design. Delivery planning should begin only after the correct low-band or high-band arrangement is confirmed for both endpoints.
Installation and configuration are separate scope items unless explicitly included in the quotation. Buyers that need path review, mounting coordination, antenna alignment, Ethernet integration, commissioning or documentation should describe those requirements at the enquiry stage. Warranty terms should also be confirmed in the formal offer because coverage can vary by supply channel and region.
Dubai, Abu Dhabi, Sharjah and Ajman project coverage
Businesses planning licensed point-to-point connectivity across Dubai, Abu Dhabi, Sharjah and Ajman can approach FourTeck for requirement review, equipment selection and quotation coordination. The useful starting point is a concise project pack containing site locations, path length, capacity objective, spectrum status, mounting details and required completion window. This allows the discussion to focus on whether AF11-Complete-LB is technically appropriate and what additional components or services may be needed. Site surveys, tower work, regulatory approvals, delivery schedules and installation dates remain dependent on project scope and must be confirmed rather than assumed.
GCC Availability
FourTeck can assist organisations planning Ubiquiti airFiber 11 projects across the GCC with requirement review, model selection, quotation coordination and deployment-scope discussions. A regional request should identify the destination country, exact endpoint quantity, assigned or proposed frequency pair, desired SISO or MIMO mode, path distance, target capacity and required installation support. These details are especially important because licensed microwave rules and permitted channel arrangements differ between the United Arab Emirates, Saudi Arabia, Kuwait, Qatar, Bahrain and Oman. Product availability, spectrum licensing, vendor lead times, delivery planning and service visits can also vary by location, quantity and project conditions. FourTeck can help structure the bill of materials and clarify which items should be confirmed before purchase, but local stock, customs outcomes, fixed delivery dates and regulatory approval should not be assumed. For regional coordination, buyers may also review FourTeck Kuwait technology support and submit the complete project requirement for a tailored response.
Africa Availability
For organisations evaluating licensed backhaul in Africa, FourTeck can support product selection, accessory planning, quotation preparation and discussion of configuration or installation needs. Buyers should share the destination country, the two site locations, exact AF11-Complete-LB quantity, frequency-licence status, intended channel plan, power environment, mounting arrangement and preferred deployment schedule. Availability and fulfilment can depend on destination, regional radio rules, duplexer choice, quantity, shipping arrangements, vendor lead time and local site conditions. Power quality, lightning exposure, tower access and rain-fade design may also require particular attention in different regions. FourTeck does not assume local inventory, country-wide onsite coverage or guaranteed customs and delivery outcomes; these should be assessed for the individual project. Buyers in East Africa can explore technology assistance in Kenya or FourTeck Uganda services, while broader enquiries can be directed through the FourTeck Africa platform.

Why businesses contact FourTeck
The most valuable assistance on an AF11-Complete-LB project often happens before the purchase order. FourTeck can help clarify whether the request covers one endpoint or a complete link, whether the selected low-band unit aligns with the approved channel plan, which duplexers and accessories belong in the bill of materials, and whether installation or commissioning should be priced separately. Buyers can also discuss Ethernet integration, mounting, power, support expectations and delivery coordination. This practical review does not replace regulatory approval or detailed RF engineering, but it helps convert a product name into a more complete procurement requirement.

Frequently asked questions
Is AF11-Complete-LB a complete two-site wireless bridge?
No. It is a complete endpoint package containing the radio, dish antenna and one low-band duplexer. A point-to-point link normally needs a correctly configured endpoint at each site, plus the supporting network, power and installation materials.
Why does the low-band version matter?
The duplexer is designed for a defined frequency arrangement. Low-band or high-band selection must match the assigned transmit and receive channels at each endpoint. The licence plan should be known before the equipment is ordered.
Does the kit support MIMO out of the box?
The complete low-band kit includes one low-band duplexer for SISO. MIMO requires a second compatible low-band duplexer and a matching configuration at the other end. Confirm the full bill of materials with FourTeck.
