Railway environment certificate
The Teldat APR222ac complies with the railway regulations and is designed to provide a Wi-Fi connection on board trains. Simultaneous use of dual band enables connection of latest generation devices to the 5 GHz band, less collapsed, leaving the 2.4 GHz band for devices with lower capabilities. It also supports advanced Wi-Fi functions like multiple SSIDs, with different access levels, logical separation and priority systems. It also supports load balancing amongst several LAN interfaces and improves user experience with automatic radio OFF if there is no internet output.
It is a flexible device that can operate as a Wireless Controller for 5 additional access points to minimise investment in HW required for small trains and it can be integrated in cloud and HotSpot management platforms.
Two 802.11ac MIMO 2x2 Wi-Fi radio modules
Two 802.11ac 2.4/5 GHz radio modules with 2x2 MIMO make it possible for the device to provide connectivity to terminals that operate on both frequency bands.
Client limiting and Band Steering
You can set a threshold for the maximum number of connected clients. When this threshold is reached, clients are diverted to neighboring APs or to the 5 GHz band, which is usually less congested.
Security through ACLs/802.11i/WIDS and WIPS
