frequently asked questions

Q.         How far can it transmit and how many repeaters can be used before the signal deteriorates?

A.         There is no limit to the number of repeaters and the signal is continuously boosted.

Q.         Is the data from the website downloadable/ printable.

A.         Data from the website is both printable and downloadable as CSV (Excel) files.

Q.         As the data acquisition system uses the GPRS network, would there be any worries of interference/restrictions of use in a factory with other machinery, such as switching off mobile phones in hospitals?

A.         Most of our business is installing systems in factories and industrial areas.  We are immune to external electrical noise.  The frequency, (Radio  Frequencies – a range available to different countries) is ‘licence free’ and is open for domestic and industrial applications.  However, we would check with a hospital before using it there. 

There is very little chance that it would cause a problem due to the very low RF power.  The RF Gateway with GSM/GPRS would be located outside any ‘mobile sensitive’ areas.
