Long Term Evolution - A 4G wireless technology
by David O’Farrell, Software Engineer, Ericsson R& D Centre, Dublin
The talk will cover the evolution from GSM to 3G, 3.5G and look more closely at 4G (LTE). It will also cover some of the software engineering issues involved in developing/testing products for these systems.
LTE or Long Term Evolution is a 4G wireless technology and is considered the next in line in the GSM evolution path after UMTS/HSPDA 3G technologies. LTE is espoused and standardized via the 3GPP or 3rd Generation Partnership Project members. 3GPP is a global telecommunications consortium having members in most GSM dominant countries.
3GPP specifications are based on GSM evolution path of wireless communications. GSM is the most prevalent wireless standard in the world and has maximum number of subscribers globally. LTE will enable applications previously unheard of. Wireless ubiquity is a given.
All consumer devices, communication and computing resources may be enabled on the wireless network courtesy of chipmakers like Intel who are eagerly building in WiMAX and LTE in future chipsets which will be embedded in all sorts of technology devices that one can imagine. Social Networking and human-technology interaction (HTI) will take on a new meaning.
David O’Farrell is a software engineer at Ericsson’s R&D centre in Clonskeagh where the Radio Network Controller (RNC) for Ericsson’s 3G/UTRAN product is developed/tested and maintained after release.
