![]() ![]() 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%. ![]() Classrooms are an average of maybe 1100-1200-sqft (so around 30-ft x 40-ft). When enabled, a Country information element is added to the beacons and probe responses. IEEE 802.11d-2001 is the 802.11 amendment that provides regulatory domain information. 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. Standard 802.11d and Cisco world-mode implementation. 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. We're trying to make our 2.4GHz network more stable and client friendly. ![]()
