Typically, a client maintains a wireless connection with one access point until the radio signal gets too weak, in which case the client must initialize the scan for a new access point that can offer a better radio signal. This handover phase can take from 100 ms to several seconds before the communication is up and running again.
The use of two or more clients on each cooperating device in motion enables a more seamless handover. Seamless roaming and redundancy is integrated as a standard feature of the Wireless LAN Ethernet Port Adapter. The adapter suits industrial applications where the Ethernet cable needs to be replaced with a robust wireless connection. The products support the requested security access, and are radio type approved for Europe, US and Canada (R&TTE, FCC, IC).
