In what cases is it favourable to use GPRS in the unit?

If you want the unit to continuously report data – for example you current position – there’s an advantage in terms of cost by using GPRS. GPRS is a cost efficient alternative to many other forms of wireless data transmission. Some emergency service centers support alarm reception through GPRS as well.

What is the margin of error in a GNSS-receiver?

The margin of error in  GNSS-receiver (e.g. GPS, GLONASS) is up to 50 meter. If you’re located in an urban environment with high buildings the margin of error can be larger. To get the best results you should be located outside in an open space and under a clear sky.

Which GSM operator and subscription form should I use in my SRT product?

It’s optional which network operator you choose to use in your product. However it’s important that the plan you choose supports both voice communication and SMS. If you intend on letting your SRT device report over GPRS, the operator plan have to support this as well. Normally our customers use a Telematic plan with voice communication and M2M. Please also make sure that the SIM card you intend to use is not PIN code protected.
