Improving the reliability of M2M devices with better signal strength

Systems are only as reliable as their weakest link and when it comes to M2M wireless -the weakest link is poor, intermittent signal strength. Low signal levels result in poor system performance, slow response times and reliability issues. For system installers and other M2M vendors, how do you ensure the very best 2G or 3G signal strength?

1. Checking the 2G/3G signal strength
Typically most M2M cellular systems will simply not work, or the performance is substantially degraded by low signal strength. This may result in data not being transmitted, irregular polling success or complete lack of connection. Some wireless devices (routers / modems) have a signal strength indication facility but these only report on the connection available to them.

An independent check of signal strength can be performed using a 2G / 3G signal strength analyser such as the Siretta SNYPER. These testers are hand held, network independent, and analyse the signal strength for all available networks. SNYPER can be connected to the deployed antenna to check the actual signal strength of the installed system.

2. Which network SIM to use?
Depending on location you may find one cellular network has a better signal strength than the other networks. The SNYPER product checks this for you without the need to buy a SIM from each network. Once the network has been decided the next step is to optimise the antenna and RF cables routing back to the M2M device.

3. Re-positioning the antenna
Fitting the antenna in the
