Potential Problems of GSM / UMTS Networks
The 2N gateway works reliably even under a 100% load. The following problems may
be caused by GSM networks:
Wireless modules cannot log in, log in slowly, or log out occasionally.
This problem may be caused by any of the following situations:
The GSM / UMTS signal is low. We recommend the minimum signal level of
approximately –80dBm. If lower, you have to change the antenna or
gateway location!
The GSM / UMTS cell (BTS) to which the wireless module is trying to log in
is overloaded. If you use directional antennas, you can direct them to more
GSM cells than one. The possibility to choose a cell by antenna directing is
considerably limited or eliminated in towns or densely populated areas
where multiple signal reflections occur. It is also difficult to select a cell
where the cells lie in a straight line before and behind the antenna. If no
selection can be made, you have to use another available GSM / UMTS
provider.
