[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.
While the Wi-Fi signal from a radio chain with 23 dBm transmit power may be attenuated by 10...15 dB when passing through a concrete wall,[3] the corresponding attenuation for Wi-Fi over Coax may be limited to the specific cable assembly loss for the width of the wall.
As expressed by the minimum acceptable received signal strength indication (RSSI) for the client device, maximum range via Wi-Fi over coax varies based on transmit power of the access point radio chain, the wireless LAN (WLAN) frequency or frequencies being transmitted, the type and length of the cabling run, assembly loss caused by the specific connectors used, and antenna gain.
Since a Wi-Fi over Coax deployment may use a single access point as opposed to multiple access points or range extenders, wireless transmission and interference is not doubled, resulting in greater use of channel capacity per the modulation and coding scheme and greater throughput (expressed in Mbps).
[6] While dual-band WLAN channels can be transmitted over coaxial cabling where an access point uses interleaved radio chains for 2.4 and 5 GHz, Wi-Fi over coax may require diplexers for concurrent use with other frequencies, such as those supported by MoCA products.
