We are now seeing a number of ranges of meters with advanced GSM integrated smart meters for load profiling and AMR. These meters are standalone units that communicate directly with the data collection facility using the mobile phone network. The method of communication across this infrastructure can be SMS (short messaging service), data call, or GPRS.
