2. DOCSIS - Wikipedia

   en.wikipedia.org/wiki/DOCSIS

   DOCSIS employs a mixture of deterministic access methods for upstream transmissions, specifically time-division multiple access (TDMA) for DOCSIS 1.0/1.1 and both TDMA and S-CDMA for DOCSIS 2.0 and 3.0, with a limited use of contention for bandwidth reservation requests. In TDMA, a cable modem requests a time to transmit and the CMTS grants it ...

4. List of interface bit rates - Wikipedia

   en.wikipedia.org/wiki/List_of_interface_bit_rates

   DDR and DDR2 memory is usually installed in single- or dual-channel configuration. DDR3 memory is installed in single-, dual-, tri-, and quad-channel configurations. Bit rates of multi-channel configurations are the product of the module bit-rate (given below) and the number of channels.

5. Satellite modem - Wikipedia

   en.wikipedia.org/wiki/Satellite_modem

   Data to be transmitted are transferred to a modem from data terminal equipment (e.g. a computer). The modem usually has intermediate frequency (IF) output (that is, 50-200 MHz), however, sometimes the signal is modulated directly to L band. In most cases, frequency has to be converted using an upconverter before amplification and transmission.

6. Modem - Wikipedia

   en.wikipedia.org/wiki/Modem

   Modems which use a mobile telephone system (GPRS, UMTS, HSPA, EVDO, WiMax, 5G etc.), are known as mobile broadband modems (sometimes also called wireless modems). Wireless modems can be embedded inside a laptop, mobile phone or other device, or be connected externally. External wireless modems include connect cards, USB modems, and cellular ...

7. Hybrid fiber-coaxial - Wikipedia

   en.wikipedia.org/wiki/Hybrid_fiber-coaxial

   To cope with needs for increased digital bandwidth such as for DOCSIS internet, cable operators have implemented expansions in the RF spectrum in HFC networks beyond 1 GHz to 1.2 GHz, [71] [72] have transitioned to only handling IP traffic in the network thus eliminating dedicated video RF channels, used digital transport adapters (DTAs) for ...

8. G.992.1 - Wikipedia

   en.wikipedia.org/wiki/G.992.1

   Using DMT is useful since it allows the communications equipment (user modem/router and exchange/DSLAM) to select only bins which are usable on the line thus effectively obtaining the best overall bit rate from the line at any given moment in time. With COFDM, a combined signal containing many frequencies (for each bin) is transmitted down the ...

9. Link aggregation - Wikipedia

   en.wikipedia.org/wiki/Link_aggregation

   Link aggregation offers an inexpensive way to set up a high-capacity backbone network that transfers multiple times more data than any single port or device can deliver. Link aggregation also allows the network's backbone speed to grow incrementally as demand on the network increases, without having to replace everything and deploy new hardware.
