Most GSM-900 operators seem to be increasing their capacity by implementing GSM-1800 network gear. Basically all new GSM phones are equipped with both frequencies. So GSM-900 guarantees coverage and GSM-1800 offers capacity in heavily populated areas. Most likely many existing analog networks will be replaced by GSM-450 for sparsely populated areas - tri-mode phones for rural areas should debut in a year or two. HSCSD is raising GSM data speed to about 40 kbps this autumn and GPRS will push it above 100 kbps next summer. Neither solution increases capacity - they just increase speed. After this it gets hazy - will there be an additional step between these two technologies and 3G? Is that the EDGE approach that would merge TDMA and GSM networks? Is there a point for 3G if this happens? We should find out during next year or so. Tero
