This allows for easy extraction of data and comparisons to be done online. What makes this unit so unique is that it is completely wireless, no electrical power, no phone lines and no high maintenance costs are required. All that is needed is cellular phone coverage and a SIM card which is enabled for gprs data from any selected cellular provider.
