#1Had 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?

#2ZTE 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

#3Boosting 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.

#5Most 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)
