Wireless over IP Transmission System (WITS):

Platform:Linux

Transmission System is intended to meet necessary Transmission System Requirement for GSM System. Transmission System consists of TDM Transmission System and Wireless IP Transmission System.

TDM Transmission System receives one or more E1 from any node of GSM System and carries it to the destination node of the GSM System without compromising the characteristics of Physical E1. TDM Transmission System may carry the required signal through IP network based on Wireless or Wire line Network elements.

Wireless IP Transmission System receives IP Traffic through Ethernet cables interface and carries it to far destination for desired range using wireless technology. For providing required wireless coverage, it uses various aspects as Multi-hops, Star distribution etc.

The proprietary protocol is implemented over MADwifi to obtain a more deterministic mechanism through the Wireless system, providing in lower and predictable latency and avoid unnecessary contention on the radio channel, guarantee bandwidth for the E1 traffic. The protocol is flexible in term of bandwidth allocation of different traffic types, E1 or TCP/IP and it has an allocated TCP/IP channel for internal system OAM purpose.
