Compare coaxial cable with wifi
Answers
Answer:
Internet isn’t something that magically appears in your home.
Unless you’re on a satellite-based Wi-Fi network, there are likely cables from an internet service provider that go directly into your residence. Not all cables are created equal, though. It might be a fiber-optic or coaxial cable, and there are some key differences between them you need to know about to choose the best broadband provider.
Fiber and cable internet both get you online, but their structures as well as limitations carry unique traits. We’re going to explain the cables behind each, how you can benefit from them and what’s the best choice for you.
Answer:
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. Coaxial cables with characteristic impedance of 75 Ω, such as RG-6 cables used for in-building television distribution, can also be used by incorporating impedance converters.[1] As part of a distributed antenna system, Wi-Fi over Coax can connect multiple floors of a home or office via power dividers and zoned antennas either passively or via amplifiers, potentially eliminating the need for multiple access points.[2]
