ExpressConnect Features
ExpressConnect provides following features and their inclusion with specific
version numbers:
1. Best Access Point Selection (BAPS) engine
• AP scoring and ranking
• Auto AP switching
• Band switching on the same AP
• Network diagnostics and telemetry
2. Network Traffic Shaping (NTS)
• Uplink packet tagging
• Dynamic bandwidth control
• Voice mode feature
Access point scoring and ranking
This feature lets the user see all available access points and their scores in terms
of bandwidth. Each access point is scored using five factors: Signal strength,
Maximum data rate, MU-MIMO capability of the access point, channel contention
and loading of the channel. These factors are acquired from the access point
beacon and use a proprietary scoring mechanism to combine these factors to
provide a final score.
Auto AP switching
This feature leverages AP scoring and ranking feature to decide the best AP to be
connected. This feature lets the client switch APs when the score of any of the
surrounding APs becomes better than the score of the AP which it is presently
connected to. A hysteresis mechanism is implemented to mitigate for erratic
behavior of wireless environment and avoid hunting issues.
