For around a hundred years, single antennas have been used, dipoles, etc. for wireless communications In the last ten years, however, this has all changed and multiple antenna systems, different types of diversity, beamforming, array antennas and MIMO have all emerged onto the wireless scene. They offer better cell capacity, more user throughput, larger cells: too many good things to be true, it seems. However, actual deployments have shown the immense value of current MIMO technology and the potential for the next few years.
The High Speed Packet Access (HSPA) addition to UMTS uses MIMO for HSPA+ to massively improve on its original 7.2 Mbps downlink so this technology, a subset of antennas for LTE, is described.
This unique two day course starts with a refresher on antenna basics before looking at diversity in all its forms and then diversity, MIMO, beamforming and array antennas. This course does not discuss the detailed physical design of antennas but is focussed on how multiple antennas, etc, are used and integrated into LTE.
