Data transmission GSM (CSD) vs. GPRS/EDGE/UMTS
GSM
Fixed assignment of voice and data channels
Physical connection to the air
Full bandwidth of a radio channel used exclusively by one user
User pays the radio channel the whole time of allocation
Pricing according to connection time
- “pay for silence”
GPRS/EDGE/UMTS
Dynamic assignment of voice and data channels
Data transfer via packages
GPRS session uses several channel in parallel
Resources are only occupied for the absolute period of time to transmit the data package
Pricing according to transferred volume
- “pay for activity”

GPRS/EDGE – a few details
Source: T-Mobile
Dynamic assignment of voice and data channel.
GPRS/EDGE Session is able to use several channel in parallel.
Resources are only occupied for the duration of transmission.
GPRS/EDGE use existing GSM infrastructure
GPRS/EDGE is a technology for packet oriented data communication (IP) GPRS/EDGE is global and area wide
packet-switching data
Combined voice and GPRS/EDGE data channel
Dedicated GPRS/EDGE data channel
GPRS/EDGESession 1
GPRS/EDGESession 2

UMTS – Core Netzwerk UMTS is using it‘s own radio access network, separated from GSM
UMTS is using W-CDMA (Wideband Code Division Multiple Access) air interface standard
The UTRAN Network logically cuts into RNSs (Radio Network Subsystem)
A RNS is a geographical region which is managed by a RNC (Radio Network Controller).
Single RNS‘s can be cuts into Location Areas (LA)
MSC, SGSN and GGSN are core components of GSM/GPRS 2G network and are used by the UMTS 3G network.

Industrial Meter communication
Can we read transparent different meter types with one modem?
Is it possible to keep the already installed meters?
How do we avoid meter reading mistakes?
Can we assure save and protected meter reading, protection against fraud?
Is it possible control and manage meter and modem remotely, without regular visits?

Smart Meter communication
How do we connect single households for smart metering?
Can we avoid vendor and product log in scenarios?
Is it possible to read all meters (e,g,w, ACs, heating, etc.), to connect also the home automation or displays?
Can we get open standard and interoperable solutions?
