Evolution of Mobile Technologies

Evolution of Mobile Technologies

Generation Definition Throughput Technologies/Spectrum Weakness

1G (1980)Analog

Narrowband (voice)

14.4 Kbps (peak) AMPS, NMT, TACS, … 800MHz

Poor spectral efficiency, major security issues

2G (1990)Digital

Narrowband Circuit data (voice, sms)

9.6/14.4 KbpsTDMA (IS-136) (AT&T)

GSM (T Mobile) CDMA (Verizon) (IS-95)

800MHz - 1.9GHz

Limited data rates- difficult to support

demand for internet/e-mail

2.5G Packet data 171.2 Kbps (peak) 20-40 Kbps GPRS Same

3G (2000)Digital

Broadband Packet data

3.1 Mbps (peak) 500-700 Kbps

CDMA 2000 EDGE UMTS

800MHz - 2.2GHz

Real performance failed to match hype, failure of

WAP for internet access

3.5G >2Mbps 14.4 Mbps (peak) 3.6/7.2 Mbps HSPA

Tied to legacy, mobile specific architecture and

protocols

4G (2010)Digital

Broadband Packet All IP

100-300 Mbps (peak) 3-5 Mbps

+100 Mbps (WI-FI)

WIMAX, LTE, WI-FI, AXGP

1.8GHz - 2.6GHzData rate and

latency

Features

Up to 10Gbps data rateLess than 1ms latency

Much higher battery life90% reduction in energy

99.999% availability Full coverage

Gaining in bandwidth efficiency by a factor of 1000

Increase in the number of users by a factor of 100
