This article dedicated to a review of modern methods of researching and estimation of
productivity of IEE 802.11 protocol, based on Markov models and allows effectively estimate
main indices of productivity of network functioning. The researches of estimation of network
functioning is taking on special significance because of adaptation of IEEE 802.11 standard
for network construction on a city and regional scale, that solved the problem of providing
data in distant regions.
A mathematical model of information transmission processes using radio link discreet
channels. This model represents the quality indicators of broadband communication channels.
The model helps to generate main quality indicators of super broadband communication
channel and to calculate the coverage of broadband access networks in field applications.
In article on the basis of the theory of reliable communication and mathematical modeling
the comparative analysis of efficiency of communication channels in conditions of the limited
by power and by a pass band without and with use of system of channel encoding is made. All
calculations and results in detail analyze on the basis of model of a plane “band-efficiency"
