QoS
QoS di 802.16e di dukung dengan cara mengalokasikan setiap sambungan antara SS dan BS (biasanya di kenal sebagai "service flow" di terminologi 802.16) pada "kelas QoS" yang spesifik. Di 802.16e, ada lima (5) kelas QoS, yaitu:
| Layanan | Singkatan | Definisi | Contoh Aplikasi |
|---|---|---|---|
| Unsolicited Grant Service | UGS | Data stream Real-time yang berisi paket dengan panjang paket dan perioda interval yang tetap | T1/E1 transport |
| Extended Real-time Polling Service | ertPS | Real-time service flows that generate variable-sized data packets on a periodic basis | VoIP |
| Real-time Polling Service | rtPS | Real-time data streams comprising variable-sized data packets that are issued at periodic intervals | MPEG Video |
| Non-real-time Polling Service | nrtPS | Delay-tolerant data streams comprising variable-sized data packets for which a minimum data rate is required | FTP with guaranteed minimum throughput |
| Best Effort | BE | Data streams for which no minimum service level is required and therefore may be handled on a space-available basis | HTTP |
The BS and the SS use a service flow with an appropriate QoS class (plus other parameters, such as bandwidth and delay) to ensure that application data receives QoS treatment appropriate to the application.
