5 ways to improve 2G/3G signal strength for M2M devices

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

Self-managing modems ensure optimum network connectivity

New linkCONNECT cellular modems actively manage cellular connection for maximum up-time

linkCONNECT modems for 2G/GPRS and 3G/UMTS provide seamless actively managed cellular network connectivity. These modems have linkCONNECT software running on them which will automatically reconnect to the network if the connection fails for any reason. linkCONNECT software deals with many inherent issues relating to 2G and 3G to ensure your system maintains the very best 2G/3G network connection possible. linkCONNECT provides RS232 pass-through to make it easy to add 2G/3G connectivity to your existing RS232 devices.
