Typical Neon Measurement System
The figure above is an example of a Neon installation showing an NRT/NRM connected to
a Water Level Instrument. Every day the NRT/NRM will send, via GPRS to the Neon
server, a “packet” of information containing the data in raw format. The Neon server
extracts the raw data from the packet. The data is then stored on a secure server until the
client accesses the data using a standard Web Browser.
1.3
The Internet
The Internet provides the transport mechanism between the Neon Servers and the
telecommunication provider gateways. This means that NRT/NRM units can be used
anywhere in the world.
1.4
GSM
GSM (Global System Mobile) is a cell phone standard in most of the world. GSM provides
the “backbone” upon which GPRS, voice and data communication travel.
1.5
GPRS
GPRS is an IP-enabled cellular solution for urban communications. The power
requirements are low and the GPRS electronics are fully integrated within the NRT/NRM.
GPRS communications are generally available wherever GSM communications are
available.
By this means a logger or field instrument connected to a GPRS-enabled communications
device (such as a Neon NRT/NRM) can deliver data to any Internet connected computer.
GPRS provides an always-connected service – i.e. there is no dial up required. Typically
the user pays for data use and not for time.
1.6
Satellite Packet Data Service
There are several low earth orbit and equatorial orbit packet data service providers. The
NRT/NRM Satellite uses the Globalstar system which is provides a service very similar to
the Cellular based GSM GPRS service over the Globalstar Satellite network
