WebRTC and 4G LTE

Among the sessions at WebRTC Conference & Expo, held in San Francisco, was “Extending 4G Communications With WebRTC.” Hosted by Anne Lee, CTO at Advanced Communications Solutions Innovations for Alcatel-Lucent, it delved into the advantages of 4G LTE and how WebRTC can assist it.

Mobile broadband has come quite a long way since the days of radio speech. While it took quite a while for mobile phone technology to reach the point where it was capable of supporting a consumer market, there are now billions of mobile subscriptions today.

Once the analog system gave way to digital, data services were added; it started with SMS, followed by CDPD, then GPRS, and so on and so forth – until it reached today’s LTE.

Today, there are 253 operators committed to LTE across the world, with 312 also investing in it. Providers such as Verizon and AT&T have begun rolling out 4G LTE networks for their customers across the United States, which is particularly useful given the challenge posted by the data explosion.

In the coming years, it’s expected that 70 percent of mobile data will be used for Web access. Mobile devices are no longer being used solely for when one is mobile, but also from home like a regular computer.

As such, mobile services have to be able to keep up with the growth in mobile data traffic it presents.

So where does WebRTC come into play? WebRTC makes it possible to add communications to the Web, providing a media engine in browsers that can create a full client. From there, IMS is used to create a sub-client, which lets people use various devices to connect to endpoints of several varieties.

With WebRTC, VoLTE/4G communication subscribers can help their friends and families use IMS services, providing advanced IMS features to a wider audience. By using 4G communications, VoIP, video, messaging and other RCS services are provided over macro wireless LTE access, while providing high download and uplink speeds and minimizing latency to under 10 milliseconds.

“WebRTC,” said Anne Lee, “is an exciting new HTML5 client technology enabling IP communications innovations on multiple device platforms integrating into millions of websites and Web apps.”

The session concluded with an explanation of how WebRTC can provide benefits for and benefit from 4G LTE. Because of 4G, the bandwidth and speeds required for WebRTC are more widely available, improving real-time communication for users all across the net.
