18 MULTIPLE WAYS WEBRTC CAN EXTEND 4G COMMUNICATIONS 1. 4G communications provides voip, video, messaging, and other RCS services over macro wireless LTE access. a. WebRTC gives VoLTE/4G comm subscribers the ability to access and use their IMS services from other devices over multiple access technologies including PCs, tablets, TVs, etc. over fixed and wireless networks b. WebRTC allows VoLTE/4G comm subscribers friends and families to use IMS services extending the reach of advanced IMS features before full interoperability between IMS service providers is achieved. 2. WebRTC can be provided on PCs, tablets, and other non-mobile devices over 4G access technology Leveraging LTE capabilities to take advantage of QoS and ANDSF may be an option 3. WebRTC can be provided on mobile phones over 4G access technology Firefox OS handsets available 2013 with circuit voice

24 CLOSING WebRTC is an exciting new HTML5 client technology enabling IP communications innovations on multiple device platforms integrating into millions of websites and web apps. WebRTC can extend 4G communications in multiple ways: 1. Web extension a) Extend access to IMS comm services beyond the VoLTE smartphone to PCs, tablets, TVs, etc. b) Allow non-ims subscribers to join a conference via a webrtc URL link 2. PCs, tablets, non-traditional devices, and other non-mobile devices on 4G 3. Mobile phones a) HTML5-based OS handsets b) HTML5-enabled smartphones web Σ F(WebRTC,IMS,4G) = Rapid Innovation n=devices
