A gateway sits at the network edge and connects the local network to other networks.
Practical example: choosing UniFi or UISP
Do not assume all Ubiquiti products belong to one interchangeable management architecture.
Scenario: A business needs managed office WiFi and switching, while a separate requirement connects remote buildings using outdoor wireless links.
UniFi is evaluated for the managed LAN, gateways, switching and access points. UISP products are evaluated for service-provider-style or outdoor point-to-point and point-to-multipoint infrastructure where appropriate.
Decision: Select the product family from the network role rather than assuming all Ubiquiti products are part of one interchangeable management architecture.
Common mistakes and selection checklist
Common mistakes
- Assuming UniFi, UISP, airMAX and related product families are interchangeable because they share the Ubiquiti brand.
- Buying a gateway, AP or switch before deciding how the network will be managed.
- Mixing product generations without checking uplink, PoE and controller requirements.
What happens if you get it wrong?
The hardware can be individually capable but form an awkward management design, require unexpected controllers or injectors, or fail to provide the intended end-to-end feature set.
Selection checklist
- Define whether the requirement is an enterprise LAN, managed WiFi, outdoor PtP/PtMP link or service-provider-style network.
- Choose the appropriate Ubiquiti product family for that role.
- Check management or controller requirements.
- Verify Ethernet speeds, PoE input/output and optical uplinks.
- Check environmental and mounting requirements for outdoor equipment.
Gateway role
In a typical business network the gateway provides the boundary between the internal LAN and the internet or another upstream network.
The supplied range
The list includes UniFi Express, Cloud Gateway products, Dream Router, Dream Machine and Security Gateway models.
Check WAN and LAN requirements
Consider internet speed, WAN count, LAN ports and the required network architecture. Multi-WAN or higher-speed connectivity can change the gateway requirement.
Choose by deployment
A small installation may need a compact gateway, while a larger network may require a different gateway class and separate switching.
