Tech Talk with SIP Print's Jonathan Fuld: Cellular Long Term Evolution - Part 1

April 12, 2010

Jonathan Fuld, Chief Technology Officer, SIP Print,

Just the other week, I attended a conference where Andrew Seybold (News - Alert)was speaking on Cellular Long Term Evolution, or 'LTE.'  Seybold is a well known advisor/consultant in the cellular world.  He hosts the annual Seybold Dinner that recognizes the accomplishments of companies that are developing leading-edge technologies, devices, services, and applications that will change the way we view and use wireless in our everyday lives and that will attract new customers to wireless.  The dinner is attended by the industry leaders, people who have made notable improvements in cellular technologies.  One of the finalists at the most recent Andrew Seybold Dinner was a company that developed a smart phone application that enabled a motorist to place a service request with AAA including the GPS co-ordinates without having to make a telephone call.

At the conference, Seybold touched on the next generation wireless network, LTE (News - Alert).  When LTE becomes common place your cell phone will have the following characteristics:

  • Download speed of 100Mbps
  • Upload speed of 50Mbps
  • Latency of about 10 ms
  • Initial Roll Out - 2010
  • All IP network


LTE is the next generation of cellular technology.  It is the first cellular technology with a focus on network applications and secondarily on telephony.  The carriers understand that the applications on the smart phones are of higher importance to the consumer than are the ability to make telephone calls.  This emphasis is a recognition that the way we communicate comes in many forms in addition to voice.  Carriers still care about offering consumers higher quality telephone calls, so what they have done with this technology is to take the voice call application and convert it from a proprietary technology to an IP application.

The new cellular network, LTE, is an all IP network.  Every application will be based upon Internet Protocol.  The coming communication convergence of the desktop, laptop, Pad, and now smart phones means an application that communicates on any of those devices will communicate on all those devices because the protocol, IP, is the standard among them all.  The costs and time to market decreases for all applications.  Application inter-connectivity increases.

Even SIP will operate over LTE.  Multiple soft phone applications using SIP will run on the smart phone.  Look for these phones and applications to be dominant within the next 18 months, replacing the current versions of Iphones, Droids, Blackberries and other cellular phones.  Even call recording for co-location cellular companies becomes more accessible - less costly to the consumer as well - call recording is another smart phone application hosted in the wireless cloud.
