Migration strategies
! Future Introduction- Deploy GSM/GPRS after 1-2 years
! Parallel Existence- TDMA and GSM/GPRS networks grown and marketedin parallel for next 1-4 years (or more)
! Aggressive Deployment- Within 1-3 years of launching GSM/GPRS services,most TDMA subscribers will be migrated

! Moving from AMPS to TDMA
! Frequency reuse patterns- 7/21 to 5/15- 5/15 to 4/12- up 90% capacity gain
