Unifi ap transmit power1/15/2024 ![]() We had adjusted the minimum possible power level in RRM to 14-dBm in an attempt to work on this, but it seems this may have been both too high and in the wrong direction. We previously had issues where RRM would configure the Tx power on the b/g radios to most of the time be either 1 or 8, not really balancing anywhere in between to limit coverage to the room to keep bleed-over into adjacent rooms at a minimum. We get complaints from users and on-site tech support of client difficulties connecting to the network or dropping connections, even limited numbers of clients being able to connect to the network (ex: we will get reports of, say, 17 clients connecting and then further devices will have difficulty connecting). Rx neighbors also tend to show up as high as -35dBm from neighboring rooms. What we typically are seeing is VERY high channel utilization on the b/g radios for access points in any given room, usually higher than 70%. Part 1 The topic of channel and transmit power is often confusing for Wi-Fi novices and experts alike, as there are several considerations to take into account: different frequency bands, varying channel sizes, and transmission power setting tradeoffs. With the outdoor UAP-AC-M-PRO-US UniFi AC Mesh Wide-Area Dual-Band Access Point from Ubiquiti Networks users benefit from a wide coverage area reaching up to 600 along with enhanced data transfer rates of up to 1300 Mbps on the 5 GHz frequency. Classrooms are an average of maybe 1100-1200-sqft (so around 30-ft x 40-ft). In the settings I set the value on custom and 16dBm. When I check my AirStats I see for my 5Ghz a transmit power of 16dBm and 20dBm (EIRP). We're a school district, and what was decided when we began the project of getting wireless into our schools was that we would be installing an access point into every classroom in our buildings. Hey folks, I'm trying to optimize my Unifi Wifi. Max Power level assignment = 30-dBm (I know, WAY too high. Any suggestions on how to go about setting a decent Tx power level for the 802.11b/g radios? What have some of you done to help improve the quality of that band?Ĭontrollers: WISM-2 modules running 8.0.140 One of the issues I want to look into is transmit power settings for that radio band. Having TX power turned way up high can generate the 'Near Far Problem'. Dual Gigabit Ethernet The UniFi HD AP offers a secondary port available for bridging. Radiation patterns can be used to better understand how each UniFi access point model broadcasts wireless signal. Radio 2G should be set to HT20 Ensure Transmit Power is set. If you have lots of access points covering a large building then having more APs turned down can on paper, be better than having less with the power turned up. Devices > YOUR-ACCESS-POINT-HERE > Config > Radios Ensure Channel Width is set to the following. We're trying to make our 2.4GHz network more stable and client friendly. UniFi allows you specify the transmit power on access points. ![]()
