The WiNG stands for Wireless New Generation. Symbol Technologies, forerunner of Motorola, Zebra and Extreme Networks, launched this marketing term in the times of wireless switches WS5100 in the moment when they release the third generation of their firmware. In that time (beginning of 2007) it was a breaking firmware with completely new user interface and Cisco-like command line interface.
The third wireless switches firmware called WiNG 3 appeared also in the first units of Motorola RFS6000 RF controllers. WiNG 4 followed on RFS4000, RFS6000 and RFS7000. It brought Wireless Firewall and AP650 support. The lates version is WiNG 5. It is already available for all the RFS controller series, ie. RFS4000, RFS6000, RFS7000 and whole NX platform. Wi-NG 5 is known for its advanced support of Dependent and Adaptive APs including AP650, AP621, AP-6511, AP-6521, AP-6532, AP-7131, AP-7522 and AP7532. CLI is slightly different from WiNG 4. Completely different is the web user interface which is Flash and not the Java any more. WiNG 5 is ready for robust WLAN implementations with many RF controllers and access points. The WiNG 5 does not support AP-5131 or AP100 access point any more.
