Try to modify the antenna mounting position, avoid the major lobe of both antenna
overlap, which is also an effective way for high isolation among different antennas,
especially for high directivity antenna.
It might be difficult to find a perfect position to stagger the major lobe for low directivity
antennas, two factors cause this, one is the major lobe is very broad, the other is the
radiation pattern is affected by surroundings sensitively.
For common antenna we often use, most of them belong to low directivity type, we
can put the antennas in a nonmetal shelf, and place antennas in vertical form, not in
horizontal form, which can help to avoid antennas major lobe overlap and make the
isolation bigger in some degree.
7. Frequency Asked Questions
7.1 Device have been connected to network physically, but cannot access the
gateway
1) Make sure the network cable is ok , can through view the device network port indicator
light to determine the physical connection is working or not;
2) Make sure the connected network devices (router, switch or hub) support 10M/100M
adaptive, if not, connect the Equipment directly to PC, landing WEB and in the "local
connection" Configuration interface Select the correct Ethernet Work Mode;
3) Check the Network Configuration, if the Configuration is incorrect, please
re-Configuration. If you are using DHCP mode, check DHCP Server is working properly;
4) Check whether there is a LAN device conflict with the exists IP ADDRESS.
7.2 Equipment can not register
If the Run LED does not flash mean unregistered
1) Check the network connection is working (see above section), whether the Configuration
is correct;
2) Check whether the LAN firewall setting is inappropriate (such whether limit the network
communication); If it is, there are two ways to try to resolve;
3) Check whether the Local Network to the SIP PROXY platform network environment is
relatively poor or not, and if so, please check Local Network or contact the service provider;
4) if go through those steps, the device still be in trouble, please contact the equipment
