High Speed Circuit Switched Data
The data rate of each timeslot is increased to 14.4 kbps
Four timeslots can be assigned to one user A maximum data rate of 57.7 kbps Advantage:
No major modification is needed in GSM network Disadvantage:
It is still circuit switched, not suit really data traffic

Mobile Data Service Providing 7
General Packet Radio System
Major modifications are needed in GSM systems
New network elements (SGSN, GGSN) A maximum data rate of 115 kbps is available,
avarage data rate is around 40 kbps Advantage:
User is charge for the bits transfered Disadvantage:
New mobile terminals are needed
Mobile Data Service Providing 8
GPRS architecture
Mobile Data Service Providing 9
Enchanced Data for Global Evolution
8-PSK – a new channel coding method – is introduced instead of GMSK
A maximum speed of 348 kbps data rate can be achieved
Advantage: Easy to deploy in the network
Disadvantage: The rate of return might be low

Investments and revenues of EDGE I.
A GPRS capable network is required The same spectrum, cells and bearers can
be applied as in case of GSM/GPRS In most cases only software upgrade is
needed BTS and BSC can be upgraded remote To cut on investment costs the EDGE
service cab be introduced in urban areas A medium penetration of EDGE capable
cell phones is favourable

Investments and revenues of EDGE II.
A higher level of utilisation throughout the network can be reached
Profitability is on the rise New services, new subscribers
Mobile Data Service Providing 12
End-user Services enabled by EDGE
All services of GPRS is available just faster: MMS, WAP Game, ring tone, image downloading Audio streaming
New services and applications Video streaming
Faster Internet access
Mobile Data Service Providing 13
Market Positioning and Pricing Issues I.
The strategies has to be significantly divers for oparators not having and having UMTS licences
Charging strategy depending on local market
Operators without 3G licence: Offer GPRS service EDGE as a premium service Reach as high coverage as possible
Mobile Data Service Providing 14
Market Positioning and Pricing Issues II.
Operators with 3G licence: EDGE to be positioned between GPRS and
UMTS Same charging strategy as in case of GPRS
(„pay for bits transfered”) Higher fees Same fees
Demand for high data rates can be mapped (easier positioning of UMTS)

EDGE in Hungary
Mobile penetration in Hungary: 78.9% No 3G licence granted yet EDGE service launched in November
2003 in parts of the capital (inner city) No extra fees for EDGE subscribers Services:
Video streaming service (News channel) WAP 2.0

The Future of EDGE
EDGE is the most cutting-edge technology for GSM/GPRS networks
Operator without 3G licence are still able to offer UMTS like services
Operators with licence have to decide whether it worth to deploy EDGE to their networks.
EDGE and UMTS are going to be on market side by side as supplementary services
Thank you for your attention!
