Communication system demand.
Background technology
Existing WOC (WIFI signal is transmitted by coaxial cable) designs, and most employing CATV signals and WIFI signal are the most double
Work mixes, then the transmission of distribution network.
This way and does not complys with requirement in laboratory test results in CHINA RFTCOM Co Ltd standard, and for former network
There is considerable influence, it is impossible to equivalence switching, relatively big to WIFI decay, affect the use effect of WIFI transmission range and WIFI antenna
Really, specific targets are with reference to following table.
≤ 7dB(at 2400 ~ 2500MHz) (WIFI is to output), this Index Influence WIFI transmission range；
>=4dB(at 7.5 ~ 1000MHz) (forward), the former network of this Index Influence CATV；
>=6dB(at 2400 ~ 2500MHz) (forward and reverse), the using effect of this Index Influence WIFI antenna.
