Ubiquiti Networks Nanostation NSM5 5 GHz 802.11 a/n access point

SKU CH-CQ0W-EXHRX

5 GHz 802.11 a/n outdoor access point with 16 dBi gain, 20 dBm output and 2×2 MIMO airMAX TDMA

  • High-gain 16 dBi antenna focuses 5 GHz signals for long-range links
  • airMAX TDMA protocol schedules client time slots to cut collisions and boost throughput
  • 2x2 MIMO with 20 dBm minimum transmit power delivers strong carrier-class performance
  • Dual Ethernet ports plus intelligent PoE simplify wiring and power delivery
  • Four LED signal indicators give instant visual alignment feedback at a glance

5 GHz 802.11 a/n wireless access point

The Ubiquiti Nanostation NSM5 operates in the 5.745 to 5.825 GHz band with 802.11 a/n support. It integrates airMAX TDMA protocol and 2x2 MIMO for carrier-class point-to-point or point-to-multipoint links. The unit delivers a minimum 20 dBm transmit power and 16 dBi antenna gain. It is suited for ISPs and installers building long-range outdoor networks.

Practical limits of the 5 GHz 802.11 a/n interface

The radio is confined to the 5.745-5.825 GHz frequency range and the 802.11 a/n standard. Throughput and link distance depend on regulatory power limits, clear line of sight and interference from other 5 GHz devices. The airMAX TDMA scheduler reduces hidden-node collisions but requires compatible Ubiquiti stations at both ends. Maximum power draw is 8 W.

What to check before ordering

Verify that your region permits operation in the 5.745-5.825 GHz band at the stated power levels. Ensure the mounting location provides unobstructed line of sight to the remote site. Confirm you have a PoE injector or switch capable of powering the device over its dual Ethernet ports. The station is not designed for indoor client access or mesh roaming.

Questions about this item

Which frequency range and gain version of the Nanostation NSM5 should I select?

The NSM5 operates in the 5.745-5.825 GHz band with a fixed 16 dBi integrated antenna, so there is no separate version or capacity to choose.

What does the 20 dBm minimum transmit power mean for real-world link distance?

A 20 dBm minimum output combined with the 16 dBi gain provides a high EIRP suitable for long-range carrier-class links, though actual distance depends on line-of-sight, interference and regulatory limits.

How does the airMAX TDMA protocol affect throughput on the 802.11 a/n interface?

The airMAX TDMA scheduler assigns dedicated time slots to each client, eliminating hidden-node collisions and delivering more consistent throughput than standard 802.11 a/n CSMA/CA operation.
