    To implement this kind of communication, a user will require a device called a SIT, (Satellite Interactive Terminal, "astromodem" or satellite modem). A suitable satellite-dish is also required. Some systems are supplied as a pre-built combination. The user receives multimedia stream transmissions via the downlink-signals from the satellite.

    Pertaining to radiocommunication service, a downlink (DL or D/L) is the portion of a feeder link used for the transmission of signals from a space radio station, space radio system or high altitude platform station to an earth station. In the context of satellite communications, a downlink (DL) is the link from a satellite to a ground station.

    High Speed Downlink Packet Access (HSDPA) is an enhanced 3G (third-generation) mobile communications protocol in the High-Speed Packet Access (HSPA) family. HSDPA is also known as 3.5G and 3G+ . It allows networks based on the Universal Mobile Telecommunications System (UMTS) to have higher data speeds and capacity.

  7. Time-division multiple access - Wikipedia

    en.wikipedia.org/wiki/Time-division_multiple_access

    This allows multiple stations to share the same transmission medium (e.g. radio frequency channel) while using only a part of its channel capacity. Dynamic TDMA is a TDMA variant that dynamically reserves a variable number of time slots in each frame to variable bit-rate data streams, based on the traffic demand of each data stream.

    Narrowband Internet of things (NB-IoT) is a low-power wide-area network (LPWAN) radio technology standard developed by 3GPP for cellular network devices and services. [1] [2] The specification was frozen in 3GPP Release 13 (LTE Advanced Pro), in June 2016. [3]

  9. Absolute radio-frequency channel number - Wikipedia

    en.wikipedia.org/wiki/Absolute_radio-frequency...

    In GSM cellular networks, an absolute radio-frequency channel number (ARFCN) is a code that specifies a pair of physical radio carriers used for transmission and reception in a land mobile radio system, one for the uplink signal and one for the downlink signal. ARFCNs for GSM are defined in Specification 45.005 Section 2.
