/* WiMAX Network Reference Model */
==== WiMAX Network Reference Model====
'''Access Service network(ASN)''': The ASN coordinates traffic across multiple Base Transceiver Stations (BTS) and supports security, handoffs and Quality of Service (QoS).
* The ASN interfaces the BTS and the all-IP core network—the CSN. Typically the ASN includes numerous BTSs with one or more ASN gateways.
