TDMA features

• Shares single carrier frequency with multiple users
  
• Non-continuous transmission makes handoff simpler
  
• Slots can be assigned on demand in dynamic TDMA
  
• Less stringent power control than CDMA due to reduced intra cell interference
  
• Higher synchronization overhead than CDMA
  
• Advanced equalization is necessary for high data rates
  
• Cell breathing (borrowing resources from adjacent cells) is more complicated than in CDMA
  
• Frequency/slot allocation complexity
  
• Pulsating power envelop: Interference with other devices
