  • Boosting Gain on the H110

    Had a question on the gain of the internal antenna for the H110 and how we can boost this up since it's not SMA accessible like other routers?

    ZTE Bavo H110 output power and antenna gain

    The transmit power (or EIRP=Effective Isotropic Radiated Power) of WLAN card in H1XX is 17~18dBm (about 50~63 mW) and antenna gain is about 2dBi. There is no method to add a high gain antenna to this device on the WiFi side; it was designed with a pair of internal antennas only. (The latest version has a dual internal antenna for diversity).

    You can still boost the cellular signal using either a high gain directional cellular band antennas such as http://www.rfwel.com/shop/home.php?cat=63 or even better use cellular amplifiers such as http://www.rfwel.com/shop/home.php?cat=6

    If need to increase the coverage of the WLAN radio consider other range extension options such as outlined in this thread: http://www.rfwel.com/forums/showthread.php?t=144

      Boosting WiFi Router Gain

      I agree with thour as indicated above .... it seldom is a good idea to boost WiFi router gain especially for in-biulding scenearios ... maybe for LOS situations e.g trying to get to an outhouse ... plus spread spectrum systems, which 802.11g uses, hate it a lot when one transmitters power is well above all else.

        WiFi uses spreadspectrum ... thought that was CDMA for cellular

          Most modern high datarate wireless communications MUST use some sort of Spreadspectrum including Bluetooth which uses both DSSS and FHSS (DSSS=Direct Sequence Spread Spectrum), (FHSS=Frequency Hopped Spread Spectrum). 802.11g uses DSSS. The reason they MUST is to minimize narrow band inteferers (esp since most on free unlicensed bands)
