3 unusual facts about Time division multiple access


Ground-to-Air Transmitter Facility

For the advanced Bomarc (IM-99B), a Time Division Data Link was planned for GAT Facilities to provide an electronic counter-countermeasures capability using a "directional hlgh-gain data link antenna…composed of' 16 stationary segments in a circular pattern 60 feet high".

Metro Balderas

Although this station is totally underground, cellular phone signals (GSM and TDMA for several providers) are able to reach the platform.

Time division multiple access

In radio systems, TDMA is usually used alongside Frequency-division multiple access (FDMA) and Frequency division duplex (FDD); the combination is referred to as FDMA/TDMA/FDD.


Low Energy Adaptive Clustering Hierarchy

Low Energy Adaptive Clustering Hierarchy ("LEACH") is a TDMA-based MAC protocol which is integrated with clustering and a simple routing protocol in wireless sensor networks (WSNs).

UTRA-TDD HCR

UTRA-TDD HCR, an acronym for UMTS Terrestrial Radio Access(UTRA)-Time Division Duplex(TDD) High Chip Rate(HCR), is a 3GPP standardized channel access method based on a combination of TDMA and CDMA (known as TD-CDMA).
