For example, if the relay station or subscriber station
is far away from the nearest base station the connection is guaranteed to it, but with low-level modulation, that is the maximum speed is slowing down.
To handle for all these traffics, WiMAX supports adaptive modulation and coding, such that the distance between the subscriber station
(SS) and the base station (BS) determines the type of modulation to be used 2].
Privacy is accomplished by encrypting connections between the subscriber station
and the base station.
Offering both base station and subscriber station
system-on-chips (SoCs) for both fixed and mobile WiMAX (802.16-2004 and 802.16e-2005), Sequans offers equipment manufacturers an all-in-one solution with full MAC and PHY functionality, enabling them to build a complete range of WiMAX network components: high-end macro and pico base stations, outdoor and indoor subscriber terminals, home gateways, and all types of mobile devices.
A recent addition to the WiMAX standard is underway which will add Ml mesh networking capability by enabling WiMAX nodes to simultaneously operate in 'subscriber station
" and "base station" mode.
The project will use the CDAM 2000-1X technology at a frequency of 825-830 Mhz covering Base Subscriber Station
(BSS) in Surabaya totaling 25,000 lines and 10 BTS, in Denpasar 10,000 line units with 4 BTS and in Balikpapan 5,000 line units with 2 BTS.
There are two different types of nodes; one is base station (BS) andother is Subscriber Station
(SSs) or Mobile Station (MS) (Fig 1).
Requests for resource allocations and data transmissions from the Subscriber Station
(SS) to the Base Station (BS) are carried in an uplink (UL) frame.
