The key factors for wireless LAN optimization to improve WiFi network performance

Wireless LAN Optimization Factors

Many optimization factors affect the performance of a Wireless LAN (WLAN). When optimizing a WLAN, one has to devise a comprehensive performance metric that represents the real world WLAN. To accurately representing a real world WLAN, the performance metric that is to be optimized has to include all the important factors. Ignoring any of these factors in the performance metric will lead to an optimization that is disconnected to the real world WLAN, which is why many claimed WLAN optimization does not really yield to an optimal WLAN performance.

WiTuners Wireless LAN Optimization has the most comprehensive list of factors included in its optimization metric on the market. This is one of the key reasons that  Wireless LAN Optimizationr leads to actual optimal WLAN performance. The list includes:

1. RF environment

• In-door office, warehouse for example

2. Building structure

• Walls by heights and attenuation (or other obstructing objects mimicked by walls)

• Excluded areas

• Floor attenuations

3. RF factors

• Radio channel

• Transmission power


• Co-channel and adjacent channel neighboring interference

• Antenna pattern

• Antenna gains

• Shadowing AP interference from other floors

4. PHY

• Access Point (AP)  PHY types

• Minimal PHY rate

• System loss

• CCA thresholds

• Noise levels


• 802.11n specific parameters

• 802.11ac specific parameters

• Channel bonding.

5. MAC

• QoS and EDCF parameters

• Hidden nodes effects

• Load balancing

• Access Point (AP) locations

6. Others:

• Type of clients (data, voice, video)

• Optimization goals

• Load requirements

• Dual band radios

• Coverage holes

Wireless LAN Optimization Tuned Configurations for optimal WLAN performance.

Other than the list of factors that is to be included into the performance metric for optimization, the list of tuned configurations includes the configuration parameters to be tuned to reach a maximum performance metric. Usually, RRM (radio resource management) based WLAN optimization only considers the RF configurations such as channel and transmission power. But RRM is insufficient, as is evident that a 5-bar signal often does not guarantee a good connection. Configurations beyond RF layer, such as MAC and PHY layers, also have significant impact on WLAN performance.

WiTuners optimizer has the most comprehensive list of configurations considered in its optimization, which differentiate WiTuners Optimizer from any other WLAN optimization solutions on the market.

The list of WiTuners Wireless LAN Optimization Tuned Configurations include:

1. Channel selection

2. Power level adjustment

3. minimum PHY rate

4. MAC parameters (EDCF parameters)

5. Number of Access Points (APs)

6. Locations of Access Points (APs)
