UMTS : Universal Mobile Telecommunication System

Third Generation mobile telecoms – 3G

to cope with increasing volumes of traffic

and new capacity-demanding apps such as video streaming & music download

developed as a global standard to assure international roaming

though now unlikely to be universal e.g. USA, China may use different standards

a development from GSM and CDMA – also known as W-CDMA

auction of licenses for spectrum

Vodafone paid £5.96billion, BT (now Mmo2), One2One and Orange paid £4bn

»

for 2 or 3 paired 5MHz channels

»

all now regretting the amounts paid!

auctions also in other countries but beauty contests in some

extremely expensive to set up the new infrastructure needed

new handsets required to deal with new CDMA technology and applications

dual purpose handsets – have to be back-operable with GSM
