Islands of Life – Planning In-Building Continuity for LTE and Beyond

24 Jun

This year will see the Frst deployments of Long-Term Evolution (LTE), the next generationof wireless access. Providers are already looking at ways to cope with 3G and LTE in high-volume, indoor and near-building locations that receive a lot of traffic. The phenomenaof dense mobile data activity can also be considered as a trend towards small cells, or themove to more and more cells to handle capacity requirements. In this context, In-BuildingSolutions are becoming more critical, increasingly complex and linked to multiple constraints.In-Building Solutions require well-considered design and planning, especially with LTE. Thispaper will demonstrate best-in-class procedures and methods for designing In-Building inlight of LTE and current trends in the mobile market.

Long Term Evolution (LTE) is the preferred development path of GSM/W-CDMA/TD-SCDMA/HSPAnetworks currently deployed, as well as a strong option for evolution of CDMA networks. This essentialevolution will enable networks to offer the higher data throughput to mobile devices that’s neededto deliver new and advanced mobile broadband services and to address capacity issues brought aboutby heavy mobile data use on 3G networks.The primary objectives of this network evolution are to provide these services with a quality atleast equivalent to what an end-user experiences with uxed DSL broadband access at home, andto reduce operational expenses with a at IP architecture. LTE has the potential to offer greaterbandwidth to a wider array of users, even those located at the edge of cells. Nonetheless, hotspotsand sites covering greater area, such as businesses, public venues and homes, will continue to see alarge share of mobile data uses.Although 3G/3.5G technologies such as HSPA/EV-DO deliver signifcantly higher bit rates than2G technologies, they do not fully satisfy the “wireless broadband” requirements of instant-on,always-on and multi-megabit throughput. Tomorrow’s wireless users, both consumers and businesses,will demand and consume improved Quality of Experience (QoE) and enriched services. With LTEdelivering even higher peak throughput and much lower latency, mobile operators (either 3GPP- or3GPP2-based) have a unique opportunity to evolve their existing infrastructure to next-generationwireless networks. As depicted in Figure 1, these networks will meet subscriber QoE expectationsin terms of real-time services such as Voice Over IP, Multi-User Gaming Over IP, High DenitionVideo On Demand and Live TV, digital signage, location based services as well as better connectivity forcollaboration, video conference, data transfer and other business needs. While initial LTE customersmay be focused on data access via USB dongles and laptops, the used of smart phone mobile, tablets,and alternative devices for machine-to-machine (M2M), will fourish. Demand ushered in by the3G revolution will carry over strongly to the new, more powerful LTE alternative.
