Wi-Fi over Coax is a technology for extending and distributing Wi-Fi signals via coaxial cables.As an in-building wireless solution, Wi-Fi over Coax can make use of existing or new cabling with native impedance of 50 Ω shared by a Wi-Fi access point, cabling run, and antenna.
In network topology, a cable modem is a network bridge that conforms to IEEE 802.1D for Ethernet networking (with some modifications). The cable modem bridges Ethernet frames between a customer LAN and the coax network. Technically, it is a modem because it must modulate data to transmit it over the cable network, and it must demodulate data ...
Balanced pair cable has higher attenuation at higher frequencies. Therefore, the longer the wire between DSLAM and subscriber, the slower the maximum possible data rate due to the lower frequencies being used to limit the total attenuation (or due to the higher number of errors at higher frequencies, effectively lowering the overall frequency ...
The F connector was invented by Eric E. Winston in the early 1950s while working for Jerrold Electronics on their development of cable television. [1] In the 1970s, it became commonplace on VHF, and later UHF, television antenna connections in the United States, as coaxial cables replaced twin-lead. It is now specified in IEC 61169-24:2019. [2]
The two phrases, "customer-premises equipment" and "customer-provided equipment", reflect the history of this equipment.Under the Bell System monopoly in the United States (post Communications Act of 1934), the Bell System owned the telephones, and one could not attach privately owned or supplied devices to the network, or to the station apparatus.
Cable operators can continue to rely on the existing provisioning and billing systems, cable modem termination system (CMTS) platforms, headend equipment, set-top boxes, conditional access technology and cable modems while gaining benefits inherent with RFoG and FTTx. RFoG provides several benefits over traditional network architecture:
At the destination end of the cable or fiber, or the radio receiver, for each channel a local oscillator produces a signal at the carrier frequency of that channel, that is mixed with the incoming modulated signal. The frequencies subtract, producing the baseband signal for that channel again.
Reception: At the consumer end, BPL modems receive the signals from the power lines. These modems are typically connected to routers or networking devices, allowing the distribution of the internet connection to multiple devices within the premises. The BPL modems serve as the interface between the power lines and the local area network (LAN).
