How many hash-based message authentication code (HMAC) keys are derived from the authorization key (AK) for communication between the subscriber station (SS) and the base station (BS)?

Encryption algorithms included in the 802.16 standard security sublayer?

Connection used for short, time-urgent MAC management messages?

Which multiplexing technology is more spectrum-efficient and cost-efficient?

The MAC layer of WiMAX does not allow variable-sized frames to be constructed and transmitted.

In OFDMA, multiple users can transmit data simultaneously.

Length (size) of the key encryption (in bits) that the DES (data encryption standard) provides?

Which certificate is used to allow the base station to identify the subscriber stations?

Which duplexing technologies does 802.16 support?

In VOIP, change in payload and code sizes of MPDUs sent by SS depends on which of the following?

In PKMv2, only the BS can authenticate the SS.
