The main task of this diploma paper is an experimental and analytical estimation of Drive - thru Internet system based on 802.11g and 802.11n protocols. Unlike the specially developed standard 802.11p, that allows transferring short official reports of urgent character only, protocols 802.11g and 802.11n allow large-scale data transfer at high speeds, and passing to free range of frequencies. The problem is - it is necessary to transfer large-scale data in short time intervals during movement of vehicle. The losses appear during transferring from zone to zone. The important parameter to estimate connection quality for internet users is Goodput parameter. It shows real amount of useful information passed by user, without account of official data. Goodput parameter is the basic parameter to estimate Drive - thru Internet system in this diploma paper. In this diploma paper on the base of experimental data several dependences for the analysis of Drive - thru Internet system have been defined and proven, such as Goodput exponential dependence on the amount of work stations, Goodput quadratic dependence on distance to base station, Goodput linear dependence on speed of vehicle. A few analytical models were developed, which confirm the efficiency of Drive - thru Internet system based on 802.11g and 802.11n as compared to existent mobile data transfer systems. Truthfulness of developed analytical models and efficiency of protocol 802.11 is confirmed also by simulation construction in OPNET. Taking into consideration this research, recommendations for construction, planning and development of Drive - thru Internet systems were established.
