UniFi AP-Long Range
Ubiquiti · ceiling access point, older generation, 200 mm dome · UAP-LR
what it is
An earlier-generation ceiling access point, 2.4 GHz band only (802.11b/g/n, two streams): a dome 200 mm in diameter and 36.5 mm high, a single 10/100 network port, passive 12–24 V power (data from the manufacturer's manual). The manufacturer marks the model as discontinued with an end-of-support date of March 1, 2021 — this is how the controller itself reports it in the device status field.
It should not be confused with the UniFi AP AC Long Range — both are called "Long Range", both are a white disc under the ceiling, yet they differ in what decides the installation:
| AP-LR (this model) | AP AC Long Range | |
|---|---|---|
| bands | 2.4 GHz only | 2.4 and 5 GHz |
| diameter | 200.0 mm | 175.7 mm |
| port | 10/100 | 10/100/1000 |
| power | passive 12–24 V | depending on the manufacturer document: 802.3af and passive 24 V, or passive only |
According to the manufacturer's manual, this access point is powered passively only — passive 24 V has to be enabled manually on the switch, and 802.3af alone will not power it. Both units we measured were plugged into switch ports without PoE, i.e. they ran from a separate power supply. That the link runs at 100 Mb/s is visible in the measurement — a switch capable of 1 Gb/s negotiated 100 Mb/s with this access point.
what we read from it
The data comes through the manufacturer's controller and — for the 2.4 GHz band — it is the same set of radio measurements that newer UniFi access points report. Measured on a working unit (firmware 4.3.28): the controller reports exactly the same statistics fields for its radio as for the new U7 Long Range access point.
- Channel utilization, broken down into the access point's own transmit and receive.
- Client count, operating channel, channel width and transmit power.
- Share of retransmitted frames — particularly telling for an extended-range access point: it rises when the coverage reaches further than conditions allow.
- Client signal quality: average and worst level, signal-to-noise ratio, the lowest connection rate of any of them.
- Link state to the switch — port number, negotiated speed, counters of link drops and errored frames.
- Traffic over the wired link and over the radio, uptime, firmware version, availability and response latency.
port layout
The front is a dome, not a flat disc as in the AC series, with a glowing ring around the embossed manufacturer logo. No ports — all connections are on the ceiling side: a single 10/100 port and a recessed factory reset button.
what we cannot read
- Anything from the 5 GHz band — this access point has no such radio.
- Temperature — the controller itself indicates that this model has no temperature sensor.
- LLDP neighbors — the access point does not report them, neither to the controller nor over SNMP. The port it is plugged into is known from the switch side.
- Several counters that newer generations report separately for each Wi-Fi network — broadcast and multicast traffic, or channel width at the network level. Radio statistics are complete; the difference concerns only these fields.

A full parameter list for this model is not here yet — the ones described above are those we have read and verified. A missing list does not mean the device exposes nothing more.
