Wireless Innovation – Only From Intelligraphics

Seamless, Intelligent Roaming
The IGX MOD37 Industrial Dual-Band Module provides advanced wireless features demanded by the market that not available in other solutions. IGX intelligent roaming changes the way wireless roaming is delivered by providing a vastly improved end-user experience. Pre-emptive signal loss detection and scan optimization greatly reduce the time needed for reconnection down to less than 100 milliseconds, ensuring the module select the optimal access point (AP). Intelligent roaming helps prevent the network stack and applications from detecting a network drop, thus improving overall application reliability and Quality of Service (QoS).

Include IGX custom configuration GUI to suit the deployment
• Roaming and scan parameters configurations
• Radio Type selection
• Power save mode configurations
• Data rates tuning

IGX MOD 37 Intelligent Roaming

Background scan optimizations

  • List of channels to scan
  • Scan Interval (if 0 do not do background scan)
  • Only return roaming candidates that meet certain minimum requirements (for example, a minimum RSSI

Background scan triggers

  • Triggers based on background scan on detection of weak RSSI from current connection and on detection of consecutive number of missed beacons exceeding the threshold value.
  • Implementation of triggering background scan on Data-rate dropping below configured threshold.

Roaming triggers

  • Triggers based on data rate, RSSI, missed beacons, and retries.

AP selection criteria

  • AP selection based on signal strength, channel load, and hysteresis (stickiness) to avoid AP ping pong effect.

Dynamic data rate tuning

  • Dynamic data rate tuning that uses signal strength and lost data packet threshold

Connection maintenance

  • The client will send a periodic keep alive to prevent an idle timeout on the AP (0-300 sec period, 0 means no keep alive).
  • The driver will not send a “Disconnect notification” event to the OS during the roaming process.
  • The driver will not send a “Disconnect notification” event to the OS during a configurable interval of time (0-10 sec) after disassociating from the AP.

Advanced Diagnostics and Debug Logging

  

Connection Maintenance

Connection maintenance algorithms:

  • The client will send a periodic keep alive to prevent idle timeouts from occurring on the AP (0-300 second period, 0 means no keep alive)
  • The driver will not send the “Disconnect notification” event to the OS during the roaming process
  • Moreover, the driver will not send this event during a configurable interval of time (0-10 sec) after disassociating from the AP
