Telecom Card in WCDMA-enabled devices.
2. Check if the server IP or port is correctly set, if 3G/4G signal is intense enough for dial up, and if dial up
via 3G/4G is successful.
3. Please check if the 3G/4G antenna is properly contacted when dial up fails. Weak signal may result in
failure to dial up; in addition, check if the SIM card has sufficient traffic; if not, dial up will also fail.
Q: What shall we do when no video is reported via 3G/4G?
A: press the "INFO" key to enter the System Information page, where you can check if the SIM card is present,
inspect signal intensity and dial-up status, and check if the antenna is properly contacted. Then, check if the SIM
card has traffic and replace it will a new one to re-check it. This is a most basic judgment criteria. If a signal is
available, while dial up fails, check if the center number and port are set correctly. Then, check if the
device number is unique.
Q
:
3G/4G signal is intermittent and video is not smooth
A: So far, WCDMA and EVDO has good coverage (4G is desired to be improved). In case where signal is
not covered in some mountainous areas or signal is weak due to local network restrictions in some suburban
areas, the video may not be smooth or even cannot be viewed. In this case, it is largely affected by the local
network; in addition, check if the frame rate for the sub stream is set too high. This may occur when
the network condition is poor while the frame rate is high.
