OFDM MAC layer is based on IEEE 802.16 MAC standard with additional
proprietary attributes, which allow for special features such as Consecutive AP
™
.
GigAccess
™
OFDM network layer enables routing and QoS queuing of traffic based on
classification of packets using information in layers 2, 3 & 4-7. In certain instances,
QoS queuing can be done using packet information (priority defined by the
management).
GigAccess
™
OFDM leverages Orthogonal Frequency Division Multiplexing (OFDM)
technology to deliver high data rates, high spectral efficiency in addition to immunity
to interference and line of site boundaries via patent pending Consecutive AP
™
technology, delivering data burst rates of up to 36 Mbps. GigAccess
™
OFDM ensures
always-on connectivity to full range of IP-based services, including fast Internet, High
Quality VoIP and Video.
GigAccess
™
provides an instant and independent infrastructure, which is immediately
deployable (self installed) with low infrastructure construction and operating costs.
In case of Non-Line-Of-Sight (NLOS) between the AU and the SU due to obstacles
such as tall buildings or mountains, a consecutive sector may be used. In this
scenario, the SU Ethernet output feeds a consecutive AU, which is used as a router
and transmits the input data over the obstacle as shown in figure below.
