The chracteristics of WiBro are:

• Peak data rate per cel:
  • 18,4 Mbit/s, downlink
  • 6,1 Mbit/s, uplink
• Cel seize: about 1 kilometer.
• Data rate per user (DL/UL): 512/128 kbit/s up to 3/1 Mbit/s
• Maximum velocity of the user: 60 km/u
• Bandwidth: 9 MHz
• Duplex: TDD
• Multiple Access: OFDMA
