World trends indicate that people are continuously seeking more connectivity and innovative means to stay in contact – especially through voice communication. This is evident by the fact that International Telecommunication Union (ITU) research data indicates that more than a billion people subscribed to telephony services in the past century.

This number has more than doubled in the last six years. Today, nearly three billion cellular subscribers are compelling operators to provide enhanced voice, data and video services.

Rick Rogers, Director, Alvarion, says that operators are looking to provide these services over a single converged network with IP being the technology of choice. The search is now on for cost effective alternatives to traditional voice networks – to supply toll-quality voice services over a wireless, broadband, mobile network. However, operators providing managed VoIP face several obstacles on the road to toll-quality service for subscribers, he adds.

“Service providers require solutions to jitter, latency, and security issues inherent to using an IP network. The WiMAX standard made provisions for inherent quality of service and strict security mechanisms, this makes WiMAX based networks the ideal solution to managed VoIP challenges.”

According to Alvarion WiMAX wireless broadband IP based networks provide operators with high quality, high speed, easily deployed, cost effective connectivity.

“By using WiMAX, operators can now provide subscribers with reliable and secure services for their VoIP applications. WiMAX networks enable operators to provide toll-quality, seamless voice and data services to their users with enhanced quality of experience. That is done while maintaining future service expansion provisions for mobile services over the same network,” said Alvarion.

“In Africa, operators are using WiMAX networks for VoIP services to businesses customers and residential subscribers. A single WiMAX network enables operators to provide both VoIP and broadband services using Alvarion’s voice gateways, which also offer interconnectivity for VoIP to legacy voice telephones. These enhanced VoIP services are the platform for improved quality of experience for subscribers,” Rogers concludes.
