LTE EPC: Drivers and Benefits of Pre-Integrated Frameworks

Overview CONTENTS Market Trends—Mobile has become the preferred source of information The OEM Challenges & Requirements pg. 2 sharing and there is a continuous launch of new and exciting Traffic Modelpg. 4 savvy multimedia applications. Applications like interactive TV, mobile video blogging, advanced games, high definition multimedia, broadcast TV Radisys LTE Ready Platform pg. 5 applications etc require very high bandwidths and minimized latency in order to give a great user experience. These and many more innovative rich media OEMs Benefits from Radisys//6WIND Offeringpg. 7 applications have created the need for LTE which is expected to offer uplink and downlink data speeds of 50mbps and 100 mbps respectively. LTE offers Glossary pg. 10 many unique advantages including increased peak data rates, increased cell References pg. 10 edge performance, reduced latency and lower cost per gigabyte. LTE is also expected to cater to the broadband market, in the short-run, primarily through fixed technologies, since it can offer competitive data rates and help operators increase their subscriber bases. LTE provides an easy migration path and is the common destination for both 3GPP and CDMA operators. It offers a big step towards the next generation of mobile technologies commonly referred to as 4G. LTE brings convergence among multiple technologies and offers unique cost advantages for operators by reducing their CAPEX and OPEX.

Early LTE deployments are expected to start from year 2010 with Verizon, NTT Docomo, Teliasonera, The OEM Challenges & Telenor, being the first ones. According to GSA Requirements report, there have been 39 operator commitments Development of LTE infrastructure is faced with a for LTE worldwide. This number is expected to grow number of challenges & requirements. The following drastically over the next 5 years as LTE is the most section lists some of the major ones faced by OEMs preferred option available for operators to cater to in meeting the needs of the operators. the ever growing subscriber demands related to higher data rates. Time to Market As subscribers become more application savvy and However, there are impediments that could impact show increasing readiness to consume new services LTE deployments all over the world. LTE is a new and that demand bandwidth and quality of experience, complex technology and requires huge investments Service Providers see both an opportunity and threat. from OEMs. It is estimated that to build LTE nodes Opportunity to increase ARPU (Average Revenue Per from scratch OEMs need at least 18-24 months to Unit) by deployment of new services and threat in take it through different stages of development, that if they don’t deploy new capacity and offer these integration, testing, lab trials, field trials etc. The nodes services in time, competition will “eat their cake”! This could require prohibitive investments of the order of is driving operators to shorten time-to-market as they hundreds of million dollars. Due to the recent economic want to be the first to launch and experiment with the downturn, most players have cut down their R&D higher bandwidth services and hence pushing OEMs investments and this is certainly affecting the LTE plans for the same. According to the GSA report, 14 LTE for many vendors. Many leading OEMs have delayed networks are targeting to be in service by end of 2010. their development plans and are looking at alternatives Most OEMs are still recovering from the economic to in-house development. Cost optimization is a key turmoil and have cut down their R&D spending. In this criteria on everyone’s mind. Many OEMs are forming situation, it seems highly unlikely that OEMs (except alliances in order to divide investments and create joint Tier-1s) will be able to deliver workable LTE solutions solutions. Product managers worldwide are facing the within the required timelines—especially if they start double edged sword—on one hand the demand for from scratch. These OEMs are looking for alternate greater data rate support is increasing ,thereby, driving solutions which would help them plug-in timelines Service Provider urgency for introducing LTE, and on mismatch and also reduce the level of investments the other hand R&D budgets are shrinking due to the required. Using pre-integrated frameworks based on current economic climate. building blocks that allow the required scalability and flexibility can help fill this gap provided the solutions have been benchmarked for required performance on leading edge silicon technologies. Such a solution would not only drastically reduce OEM delivery timelines but also help them focus their effort on their application strengths and value adds.
