Antennas for LTE and 4G
The Road to MIMO and Beyond
Course Description
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 system.

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.

Technologies such as IEEE 802.11n, Mobile WiMAX, HSPA and LTE are all dependent on their antenna systems for their performance. The newest and therefore most advanced usage is for LTE so some time will be spent on antennas for that technology and its predecessor, HSPA.

This unique course starts with a refresher on antenna basics before looking at diversity in all its forms and then diversity, MIMO, beamforming and array antennas.
Target Audience
Anyone needing an in-depth understanding of Antennas for LTE and 4G. Such attendees would be employed by or contracted to operators, manufacturers, integrators or regulators.

Equipment Requirements
(This apply's to our hands-on courses only)
BTS always provides equipment to have a very successful Hands-On course. BTS also encourages all attendees to bring their own equipment to the course. This will provide attendees the opportunity to incorporate their own gear into the labs and gain valuable training using their specific equipment.
