5.Installation of the Modem
This chapter gives you advice and helpful hints on how to integrate the TT4031
and then the read the information in this section before starting your integration work.
5.1Where to Install the Modem
There are several conditions which need to be taken into consideration when designing your application as they might affect the modem and its function. They are:
5.1.1Environmental Conditions
The modem must be installed so that the environmental conditions stated in the Technical Data chapter, such as temperature, humidity and vibration are satisfied. Additionally, the electrical specifications in the Technical Data section must not be exceeded.
5.1.2Signal Strength
The modem has to be placed in a way that ensures sufficient signal strength. To improve signal strength, the antenna can be moved to another position. Signal strength may depend on how close the modem is to a radio base station. You must ensure that the location at which you intend to use the modem, is within the network coverage area.
5.4.5Degradation in signal strength can be the result of a disturbance from another source, for example an electronic device in the immediate vicinity. More information about possible communication disturbances can be found in section Possible Communication Disturbances
When an application is completed, you can verify signal strength by issuing the AT command AT+CSQ. See “AT+CSQ Signal Strength”.
Tip! Before installing the modem, use an ordinary mobile telephone to check a possible location for it. In determining the location for the modem and antenna, you should consider signal strength as well as cable length
