Tech 3. Broadband WirelessAccess (BWA)

Typically deployed for fixed wireless accessapplications

An alternative to DSL

Emerging markets and rural areas Suitable for cellular backhaul

Relatively new technologies

In existence since 2000

Commonly use non-cellular spectrum over 2

GHz

No support for mobility, mostly proprietarysystems with lack of support from major vendorsand service providers.

OFDM & OFDMA


26/30

OFDM & OFDMA features

In OFDM, user devices are assigned timeslots for transmission, but only one userdevice can transmit during a single time slot.In OFDMA, sub-channelization enablesseveral user devices to transmit at the sametime over the sub-channel(s) allocated tothem.

SOFDMA brings an additional advantagesover OFDMA. Its scales the size to the FastFourier Transform(FFT) to the channelbandwidth in order to keep the carrier

spacing constant across different channel
