WLAN high-density deployment is carried with proper planning and implementation of Wi-Fi networks in dense environments. here dense environment is something such as stadium or educational institute deployment.
Below technique can be used for high density deployment
High-Density Deployment Location Analysis:
A location survey is crucial in analyzing the blueprint of location, physical layout, possible interference, user density, and device types(need to consider all device types like legacy 802.11a/b/g/n/ac and new tech devices as 802.11ax supported).
High-Density Deployment Band allocation:
Wi-Fi channels need to be configured in such a way it minimizes interference.
High-Density Deployment Channel Configuration:
Using static channels with 20MHz on the 2G,5G and 6G bands. Nowadays most of the clients or devices are supported with 5G radio ,then possible try to use 5G and 6G band to avoid co-interference.
High-Density Deployment Rate limit per User Configuration :
Rate limiting per user can help in managing airtime fairness and prevent one or more devices to uses most of the wlan bandwidth.
High-Density Deployment Power Configuration :
Reducing the transmit power can help in reducing coverage area which in turn reduces the count of client devices on AP
Most of the time Radio resource management take care of TX Power for seamless roaming of clients between AP’s and statically configuring min and max power can help RRM reduce or increase power in provided range.
High-Density Deployment Antenna Usage :
Most of the times directional antenna is used in wireless high density design which take care of low gain ,high direction and limit user coverage for seamless roaming .
High-Density Deployment Enabling Band Steering:
If 2.4GHz devices are also going to be part of device types used in deployment then it is mandatory to enable band-steering in our deployment because Over lapping co-channels in 2.4GHz can introduce interferences and slowness of network. So enabling band-sterring can help 5G devices move 5GHz channels for better usage.
High-Density Deployment Load balancing:
Load balancing(802.11v) or BSS transition should be enabled to aviod AP’s performace degradation towords client.
High-Density Deployment Dual or Tri-Band radio configuration:
It’s a feasible and reliable technique to configure dual 5G on radio template , so that both radios can serving at 5G.
For example : UNII-1 & UNII-3 on radio1 and UNII-2 &UNII-2 Extend on radio2. These kinds of segregation of channels over the radio can help clients to connect or do intra-band roam between radios to have reliable communication. Nowadays 6G band is available in the market, so making use of the 6G band in the deployment process along with 5G band is very helpful.
