To address globally and locally road traffic growth and its effects, it is necessary to involve the high technology in the auto industry. As a result vehicles networking feasibility studies are up to date, and are considered the new challenges and opportunities in both science and auto industry. The new initiative's main task is to create an intelligent transportation system (hereinafter - ITS), that using communication and information system solutions will be able to cut the negative impact of road transportation, to increase the transport efficiency and to provide passengers access to Internet resources. Modern cellular systems theoretical download speed is up to 150Mbps, but in practice the data exchange is ten times lower. The cost of constantly using the communication systems of data exchange service is at least four times higher than the fixed Internet connections. Therefore, it is necessary mobile technology solutions in vehicular environment, which will be widely available as cellular networks, the cost will be fixed Internet connection price range and the throughput will be higher than almost modern cellular systems provide. For vehicle networking is set up an international standard - IEEE802.11p [2], which is known as Wireless Access in Vehicular Environments. This standard has been created based on IEEE802.11a standard by reducing throughout two times and increasing distance up to four times for the primary be able to send short messages for road traffic safety and efficiency, while secondary to provide Internet access. Whereas latest wireless local area network technological solutions such as IEEE802.11n[3] can ensure compatibility with previous standards, are widely available and equipment costs are 10-100 times lower than cellular networks. IEEE802.11g/n standard communication solutions theoretically supports up to 600Mbps throughput for both stationary and slow-moving users, but despite this fact, there are no limitations to investigate these standards in a vehicular environment.
