TDMA for ordinary 802.11a/b/g/n hardware is here

NETSHe Lab Ltd. has implemented time division multiply access for ordinary 802.11a/b/g/n hardware.

Presentation at http://www.netshe.ru/files/doc/en/netshe_tdma_pres_en.pdf provides brief overview for the implementation.

=======================================================================================
NETSHe Lab Ltd. presents time division multiply access (TDMA) implementation for ordinary 802.11 a/b/g/n equipment

Goal TDMA advantages in comparison with the CSMA/CA

TDMA does not provide throughput degradation during the traffic and (or) amount of nodes increasing in the network

Predicable latency

TDMA is introduced for:

Carrier's backhaul

Access network

Specialized network with latency / throughput sensetivity applications

TDMA is introduced for:

Carrier's backhaul

Access network

Specialized network with latency / throughput sensetivity applications

Implemented network topologies for TDMA:

MESH-network

Point to Point (P2P)

Point to Multi Point (P2MP)

Some valuable TDMA features:

Configurable time-slot sizes in 40, 20, 10, 7 milliseconds

802.11n features are supported (except A-MPDU)

Built-in A-MSDU (frame aggregation) implementation for all modes

Adaptive bitrate and retransmission support.

Built-in frame compression

Traffic encryption support

5/10/20/40 MHz channel widths for all modes

Channel shifting with 1MHz step

Batman_adv support

Implementation details

Implemented as an standard Linux wireless stack extension. Modified stack is fully backward compatible with unmodified stack. All wireless chips which are supported by ath5k, ath9k drivers, are supported too. TDMA support for any wireless chip which has drivers for mac80211 stack is possible.
Fresh compat-wireless is used to provide compatibility with variety kernels.

Licensing:

NETSHe Lab Ltd. offers flexible licenses for TDMA:

Soure codes of modified compat-wireless
Wireless drivers and stack in a binary form for the specified Linux kernel version.
Custom firmwares (with NETSHe)
