Sobivanje standarda IEEE 802.11ax s starejšimi različicami

MAZOVEC, MIHA (author), Zimic, Nikolaj (mentor)

V diplomskem delu analiziramo kompatibilnost novega standarda brezžičnih omrežij, standarda 802.11 ax, z ostalimi različicami tega standarda. Prva poglavja so namenjena zgodovinskemu pregledu razvoja standarda 802.11, vse do najnovejše različice 802.11 ax. Spoznavamo predvsem teoretične osnove in posamezne novosti in izboljšave, ki jih je vpeljala posamezna različica. Nato sledi kratko poglavje o simualcijskem ogrodju Ns3, ki nam bo v pomoč pri izvedbi vseh potrebnih simulacij za kasnejšo analizo dobljenih rezultatov. Glavni poudarek izvajanja simulacij je bil na kompatibilnosti različice ax s starejšimi različicami. Iz simulacij smo izvedeli, da je različica ax kompatibilna z ostalimi, vendar pri tem pride do zmanjšanja performans, saj starejše različice ne podpirajo vseh novosti, ki jih uvaja ax.

• Title: Coexistence of IEEE 802.11 ax standard with older versions

Abstract

In this thesis, we analyze the compatibility of new standard for wireless networks, the 802.11 ax, with older versions of this standard. The first chapters are devoted to a historical review of the development of the standard 802.11, all the way up to the latest version 802.11 ax. Then follows a short chapter on the network simulation 3, which will assist us in the implementation of all the necessary simulations for later analysis of the obtained results. The main focus of the implementation of simulations is to prove, that version ax is compatible with older versions of 802.11 standard. From the simulations we learn, that the version ax is compatible with other version, but when this occurs, we get reduction of performance, since older versions are not compatible with all the innovations introduced by ax.
