For a detached workspace that needs a dependable connection, favour Ethernet to the building and a local access point if a suitable cable route can be assessed. If a cable is impractical, mesh needs a stable signal between buildings; a dedicated point-to-point bridge is another option where external endpoints can be mounted and aligned. Neither wireless route can be chosen reliably from an advertised coverage figure alone.
Video calls, remote access and file transfers make the connection between buildings more important than a strong Wi-Fi signal beside the house. Where a suitable cable route is feasible, Ethernet can carry the connection to an access point inside the office.
The choice depends on whether a wireless signal can cross the actual gap and building walls reliably. If it cannot, assess a cable route or a dedicated building-to-building bridge rather than judging the setup by whole-home coverage claims.
Mesh is worth considering where nodes can maintain a stable link. A point-to-point bridge needs suitable mounting and alignment at both buildings, as well as checks on the equipment’s operating conditions.
Start with the route between the buildings, then choose equipment for Wi-Fi inside the workspace. Distance, walls and the available cable or mounting positions can change which route is practical.
Choose when: the office needs consistent connectivity and a suitable cable route can be assessed.
Trade-off: the cable route, exposure, entry points and terminations need property-specific assessment.
Choose when: a proposed node position maintains a stable wireless link to the main building.
Trade-off: walls, obstacles and radio noise can weaken that link, as Ubiquiti’s mesh guidance notes.
Choose when: cabling is impractical but both buildings have suitable positions for aligned external endpoints.
Trade-off: it needs mounting, Ethernet and power at both ends; Ubiquiti says its Building Bridge can switch from 60 GHz to 5 GHz when bad weather disrupts the 60 GHz link.
| Priority | What to check | Your needs |
|---|---|---|
| Work connection | Check whether a complete Ethernet route to the office is feasible, where the office access point would sit, and whether the installed cable system suits the route. TP-Link describes Deco Ethernet backhaul as faster and more stable than a wireless link between nodes. | I rely on video calls or remote access and want the connection into the office to avoid a weak wireless hop through the outside walls. |
| Wireless path | Test the proposed mesh-node positions with doors and buildings in normal use. Check the signal between nodes, not just the signal from the office node to a nearby device; Ubiquiti notes that thick walls, obstacles and radio noise can degrade wireless mesh. | If I cannot run a cable, I need to know whether the signal crossing the gap stays stable where the nodes would actually go. |
| Outdoor equipment | For exposed equipment, check the exact model’s environmental rating, mounting position and power-over-Ethernet compatibility. An outdoor access point still needs an upstream network connection; its enclosure rating does not establish a reliable link through a building. | Equipment mounted outside must suit its exposure, while Wi-Fi inside the office may still need its own access point. |
| Cable route | Have the full route, cable specification, exposure, entry points and terminations assessed. Prysmian specifies Cat6 data transmission of up to 1 Gbps over 100 m for the appropriate cable system and lists a separate outdoor Cat6 variant. | I want the cable chosen for the installed route, not solely because it carries a Cat6 label. |
| Bridge installation | Check whether both endpoints can be mounted and aligned with a viable radio path, and how the chosen model behaves in poor weather. Confirm the exact radio configuration against applicable Ofcom technical conditions. | Where a cable cannot reach the annexe, I can consider an external bridge if there are workable mounting positions at both ends. |
A node in the office still needs a robust connection back to the home. Ubiquiti notes that thick walls, obstacles and radio noise can degrade wireless mesh, so a whole-home coverage figure cannot settle this question.
Test a proposed node position before committing to more nodes. If the link is weak, assess Ethernet or a dedicated bridge instead.
A cable category describes transmission capability, not every condition in which the cable can be installed. Prysmian lists an outdoor Cat6 variant separately from its other data cables.
Ask a qualified installer to assess exposure, the route into each building, cable specification, terminations and complete channel length.
An enclosure rating addresses equipment exposure, not every cause of a disrupted connection. Ubiquiti says bad weather can interrupt its Building Bridge 60 GHz link, prompting a switch to 5 GHz.
Check the mounting and alignment as well as the enclosure, and understand the chosen bridge’s behaviour when its primary link drops.
These brands illustrate different parts of a detached-building network; a brand’s range does not establish that a particular product suits your route.
Its Deco guidance covers mesh with Ethernet backhaul, while its outdoor access-point range includes equipment for exposed mounting positions.
Its building-bridge products are relevant where two external endpoints can form a dedicated link between buildings.
Its cable information is relevant when specifying the fixed data-cable portion of a wired connection.
These four multi-unit systems are options for the mesh route, where a stable link between buildings is possible. Their product details do not establish performance at a particular office or annexe; check the proposed node positions before relying on a wireless connection.

A three-unit mesh option if node positions can provide a suitable link to the workspace. Its listing describes wired and wireless combined backhaul, two 1.0 Gbps Ethernet ports per unit and setup through the Deco app. Keep the units away from rain, moisture and liquids; check the actual inter-building signal before relying on wireless backhaul.
No image available
This router-and-two-satellite mesh gives you positions to assess for a wireless link to the detached building. The listing specifies a 2.5 Gbps LAN port on each satellite and setup through the Orbi app. Check the signal at the proposed satellite position, and confirm the required wired-backhaul arrangement before planning to use one.
No image available
A three-unit mesh to consider where the house-to-office signal can support wireless backhaul. The listing describes 2.5 Gbps Ethernet ports and setup through the Deco app. It warns against exposure to rain, moisture or liquids; check node placement and confirm wired-backhaul support if that is part of your plan.

This three-unit mesh is another wireless-route option if the proposed nodes can maintain a suitable inter-building link. Its description identifies a dedicated backhaul band and Deco-app setup. Check the actual signal path; if you intend to connect nodes by cable, confirm the Ethernet port configuration and wired-backhaul support for this model.
Choose Ethernet to an office access point when a suitable route can be assessed and the workspace needs a consistent connection for demanding work. TP-Link describes wired Deco backhaul as faster and more stable than a wireless link between nodes; the cable route and installation still need to suit the property.
Not by itself: an outdoor access point needs an upstream network connection, and its weather rating does not prove that a signal will cross the gap or penetrate the office wall. Check the network feed, mounting position and exact model’s environmental and power requirements.
Measure and assess the complete installed channel, not only the open space between buildings. Prysmian specifies Cat6 for up to 1 Gbps over 100 m for the appropriate cable system; the actual cable, route and terminations also matter.
Check for suitable mounting and alignment at both buildings, a viable radio path, Ethernet and power at each endpoint, and the chosen model’s behaviour in poor weather. Confirm its band and configuration against applicable Ofcom technical conditions before installation.
