Course Description:

TETRA (Terrestrial Trunked Radio), was engineered from the outset to meet the particular needs of public safety users. Standardized by ETSI, TETRA shares many basic technology elements with cellular mobile telephony but with added unique mission critical features such as instant connection, push to talk, direct mode, and group calls. TETRA is continually evolving, with a rich range of additional capabilities meeting the increasing needs of its users. In the same way as cellular systems have developed to add higher speed data services, TETRA has also evolved with the introduction of TEDS (TETRA Enhanced Data Service) giving a significant increase in wideband data capability.
During this time cellular systems have moved through two generational shifts from 2G to 3G/HSDPA and now to 4G/LTE. With each step, data speeds have increased and now are much faster than is possible in TETRA even with TEDS. Although there is nothing on the horizon that can compete with TETRA voice services, some operators and prospective customers for TETRA are seeking to migrate to LTE for broadband data services. This course discusses the potential for migration to a broadband data service which will still provide the necessary capabilities for public safety and critical users, working with TETRA’s unrivalled voice capabilities.
