2. Supports different cell sizes in accordance with the cellular layer system.
3. 802.16 System / m able to provide a mechanism reliable network security and efficient for protect the network itself, and the user's system.
4. Operate on the bandwidth 50-20 MHz or more
5. Operates at a frequency of less than 6 GHz.
6. Duplex schemes: using TDD, FDD and HFDD
7. Legacy support: Mobile System Profile Release 1.0. In it there are settings:
- Ability to operate with legacy BS
- 802.16 / 802.16 m / e can operate at carier same RF bandwidth same / different.
- 802.16 / m can support the handover of almost identical to the legacy of the legacy MS BS and vice versa.

Functional Requirment
1. Peak data rate:
- Downlink (BS to MS)> 6.5 bps / Hz and uplink (MS to BS)> 2.8 bps / Hz.
2. Latency
- Data latency: send only one MAC Downlink and uplink PDU maximum 10 ms.

Wimax Implementation in Indonesia
In Indonesia, the first test conducted in Aceh during the post Tsunami.kesiapan pengembangangan this technology is still lagging when compared with other countries. Wimax implementation in Indonesia is still constrained in the frequencies that will be used. Frequency settings with 3G technology is still considered a constraint. In addition, there
imbalance between government regulation that has not finished with wimax technology developments that continue to run.
