"Wi-Fi will compliment data offload applications, which is something that all operators are implementing worldwide. India also has started (on this). By the end of 2015, Wi-Fi will be a reality in India. It will be there in top 20 cities in India, full coverage," Rahul Pandey, director - sales (SAARC Countries) at UTStarcom, said.

Wi-Fi is the popular term for a high-frequency wireless local area network technology.

UTStarcom, with its operation headquarters in Hong Kong, recorded a $160 million turnover in 2013, with India being the second highest market after Japan. The company has been present in India since 2000 and has worked extensively with private and public players in deploying telecom infrastructure.

"After 2G, everyone (operators) came to 3G and paid for spectrum. There will be a stage they will be running out of spectrum to expand. So, that is the time, typically, when Wi-Fi comes in," UTStarcom chief executive officer William Wong said.

"When Wi-Fi comes in, the cost of carrying data will be around one-tenth. If they want to offload the traffic on 3G or 4G and move it to Wi-Fi, the operating expenses will be dramatically reduced. That's what exactly we see in Japan," he added.

The company is working with a host of operators and they are bullish and determined on Wi-Fi connectivity.

"They will be doing in phased manner. Some of them have started in trail phase," Pandey said, declining to name the operators. The company met Telecom Secretary Rakesh Garg in September 2014. Communications and IT Minister Ravi Shankar Prasad went to Japan after Prime Minister Narendra Modi's visit. Prasad inspected the UTStarcom deployment there."We have deployed more than 500,000 hotspots (Wi-Fi area), which means 1.5 million access points. The telecom secretary showed interest to replicate it in India," Pandey said.
