Course description
Radio Planning for LTE, long term evolution networks introduces new opportunities as well as challenges. Great spectrum flexibility and spectrum allocation alternatives contribute to the complexity. The OFDMA radio standard meets very high performance expentations and is designed for inter-system mobility and service interworking across 2G and 3G systems. Cell edge performance can no longer rely on soft handover, while Inter-cell interference levels still must be taken into account. Multi-antenna installation using MIMO will contribute to capacity increase in some occasions, while in others situations, beam-forming techniques will be used.The course explores the new opportunities in the radio planning area, including multi-band and advanced antenna aspects. Guideline principles are explained and performance figures are calculated, presented and discussed.Forthcoming new features like Carrier aggregation, CoMP and closed loop MIMO are explained, as well as extended cell coverage on 800-900 MHz.
