EETimes India - December 1, 2008 - (Page 3) Trends Innovations advance mobile VoIP continued from page to offer voice over Wi-Fi in their Wi-Fi covered areas. Promising technologies Mobile operators, on the other hand, are upgrading to 3G in order to support their growing subscriber base and address their continually falling ARPU figures. 3G will aptly provide the required bandwidth for highermargin services and fixed mobile convergence (FMC). FMC proposes to seamlessly extend voice as well as non-voice services on fixed and mobile networks. IP Multimedia Subsystem (IMS) provides a simplified and futuristic framework for fast deployment of revenue generating innovative multimedia services on any access network and on any device and is being looked at as the long-term FMC solution. IMS-based voice call continuity (VCC) seamlessly hands over voice calls between mobile and fixed networks. This ensures uninterrupted service as a user a equipped with dualmode phone roams out of mobile coverage into a Wi-Fi coverage area inside a building, and vice-versa. Femtocell and UMA are other FMC technologies that claim to be panaceas in their own ways. These technologies aim to improve last-mile access and provide channels to reach the core mobile network without providing a framework for Discuss Are security tools ready for mobile VoIP? Given that VoIP is prone to security threats, are current protection mechanisms ready for its widespread adoption on mobile phones? Discuss. fast development and deployment of future FMC services. TRAI’s move to allow mobile vir- tual network operator (MVNO) agreements also enables fixed operators and ISPs to offer FMC services across multiple bearer networks. WiMAX technology is also being contemplated by operators to provide coverage in greenfield networks. Low CAPEX and OPEX make a business case in favour of WiMAX. Simultaneously, meshWi-Fi is also witnessing fast deployments and is already present in several cities. Commoditisation of Wi-Fi access points makes it economical to deploy mesh networks. Furthermore, Wi-Fi also obviates the need for expensive licensed spectrum. The reduced VoIP ARPU offered by mesh Wi-Fi also makes it attractive for rural India. Both Wi-Fi and mesh technologies will lead to increased VoIP adoption and also provide bandwidth for high-ARPU multimedia services.

Technology innovations have solved the inhibitors of VoIP adoption, such as poor voice quality and intense power requirements. With regulatory changes and new network deployments gathering pace, we now enter an exciting phase of the Indian communications market.
