Fixed Wimax ( Worldwide Interoperability for microwave access) is IEEE 802.16d standard , Fixed wimax means that CPE has to be fixed at one place and latched to the base station from which it has to communicate . In fixed Wimax base station and CPE , both are installed outside that is both are outdooe device . one CPE is associated with one base station only and one base station can be associated with more than one CPE's.
Mobile Wimax is 802.16e standard . In mobile Wimax , Base station base station is fixed but cape can be movable , here CPE can be the outdoor device or it can be dongle.
As CPE moves from coverage range of one base station to another base station , The CPE can be latched with another base station without any communication break , this process is known as handoff , here CPE compares the signal strength between the two base station and associates itself with the base station having strongest signal strength when the weaker signal strength falls below the threshold level , The process of handoff is controlled by ASN ( Access service network) i.e ASN is responsible for handoff without any communication break.
