- Long range transmission distance
- Real-time transmission systems
- Delay time very short less than 500ms
- Perfect image quality, brighter colors and image smoothness.
Introduction:
When data over uplink increases, more communication capacity is allocated. This is taken away when the traffic load becomes lighter. It operates by toggling transmission directions over a time interval, which occurs rapidly and is barely visible to the user. TDD supports voice and symmetrical as well as asymmetric data services. It also handles a dynamic mix of both traffic types. The capacities of downlinks and uplinks are altered in favor of one direction over another by providing greater time allocation through time slots to downstream transmission intervals than to upstream ones.
Well known examples of TDD are:
- Half-duplex packet mode networks based on carrier sense multiple access
- IEEE 802.16 WiMAX
- PACTOR
- Digital enhanced cordless telecommunications (DECT) wireless telephony
- Universal Mobile Telecommunications System 3G supplementary air interfaces
- TD-CDMA for indoor mobile telecommunications
- TD-SCDMA 3G mobile telephony air interface
