The choice of ETSI
It can extend the existing
GSM core network,
maximizing reuse of
existing equipment
can also overlay TDMA and
CDMA networks
Implementation is a
challenge
Supports data rates up to
2Mbps
The capacity is 50-80
channels per carrier

Developed by 3GPP2
CDMA2000 1x and
CDMA2000 3x are ITU
approved 3G standards
1x uses 1.25MHz
bandwidth support data
rates from 144kbps to
307kbps
1x EV-DO supports
383kbps to 2.4 Mbps
3x use 5MHz bandwidth,
support data rates up to
2Mbps
3G Enabling Technologies
MExE

Standardize the environment for executing moble applications
across the full range of 3G devices
Classmark is used to categorize mobile devices. Classmark 1
relates to WAP, 2 supports Javaphone API, 3 supports J2ME
Bluetooth

Conceived by Ericsson in 1994, developed by Bluetooth Special
Interest Group
A de facto standard enabling wireless connectivity between
devices
Provide low cost, low power, secure, efficient, high capacity, ad

3G Applications & Usability Analysis
3G applications include communications, information,
entertainment, and m-commerce.
3G offers better system capacity, high-speed wireless
Internet access and wireless multimedia services (audio,
video, image, data)
Vastly improved interactivily and visual impact
3G devices improved with enhanced battery capability,
larger screen, higher resolution, more memory, greater
storage capacity
Entertainment services become streamlined and viable
across various devices
Sufficient networks and compliant devices are required
