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 ...
Contention in a wireless or noisy spectrum, where the physical medium is entirely out of the control of those who specify the protocol, requires measures that also use up throughput. Wireless devices, BPL, and modems may produce a higher line rate or gross bit rate, due to error-correcting codes and other physical layer overhead. It is ...
The Multimedia over Coax Alliance (MoCA) is an international standards consortium that publishes specifications for networking over coaxial cable.The technology was originally developed to distribute IP television in homes using existing cabling, but is now used as a general-purpose Ethernet link where it is inconvenient or undesirable to replace existing coaxial cable with optical fiber or ...

The TP-Link Archer BE900 wireless router was available to consumers in April 2023. [53] The company's Deco BE95 mesh networking system was also available that month. Asus, Eero, Linksys and Netgear had Wi-fi 7 wireless routers available by the end of 2023. The ARRIS SURFboard G54 is a DOCSIS 3.1 cable gateway featuring Wi-Fi 7. It became ...
In most residential broadband technologies, such as cable Internet, DSL, satellite internet, or wireless broadband, a population of users share the available bandwidth. Some technologies share only their core network , while some including cable internet and passive optical network (PON) also share the access network .
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 ...
A CMTS may also act as a bridge or router. A customer's cable modem cannot communicate directly with other modems on the line. In general, cable modem traffic is routed to other cable modems or to the Internet through a series of CMTSs and traditional routers. However, a route could conceivably pass through a single CMTS.
