• Technology : c++ linux Unlicensed Mobile Access (UMA) Technology.
• Project : Unlicensed Mobile Access is an extension of GSM/GPRS mobile services into the customer's premises that is achieved by tunneling certain GSM/GPRS protocols between the customer's premises and the Core Network over a broadband IP network, and relaying them through an unlicensed radio link inside the customer's premises. This is a complement to traditional GSM/GPRS radio coverage, used to enhance customer premises coverage, increase network capacity and potentially lower costs.

• Technology : C++ CDMA, SIP and SS7 over IP.
• Role / Responsibility: Designer, developer and integrating tester.
• MINS is an IP based solution that is designed to cater 1000 subscribers. It supports all the features and functionalities provided by the legacy switching systems. It comprises of IP based MSC, BSC, HLR, VLR and other nodes present in a traditional CDMA network. MINS design assumes that all the subsystems reside on the same Sun Solaris server. The design uses the Reliance Data Network to carry all the signaling traffic. The transport used for signaling interface is IP.
