The IEEE802.11n capability analysis model based on mobile networking architecture

Since the IEEE 802.11n is implemented with OFDM (orthogonal frequency division multiplexing) and MIMO (multiple input multiple output) techniques, the maximum transmission rate can achieve up to 600 Mbps. As compared with the mobile wireless broadband technology, the maximum transmission rate of 3.5 G (HSDPA) and Mobile WiMAX is apparently insufficient (i.e. less than 4Mbps in the upstream) whereas the IEEE802.11n is primarily adopted in the fixed networking environment (FNE). Therefore, provided that the advantage of IEEE802.11n bandwidth can be endorsed under the mobile networking architecture (MNA), the bandwidth bottleneck of 3.5G (HSDPA) and Mobile WiMAX can be addressed and the differentiated application can be fulfilled in the Mobile Wireless Broadband Industry. In this paper, we propose a new model to analyze the capability of IEEE802.11n operated in the Mobile Networking Architecture. By using this model, we can emulate the vehicular ratio within the signal coverage via the frequency emulation module (FEM) and analyze the capability of TCP/IP under the multiple access point (MAP) mode. According to the result of experiment, the TCP/IP capability of IEEE 802.11n is optimal in the low-rate vehicular Internet environment (VIE). The capability analysis result proved that the proposed capability analysis model (CAM) of IEEE 802.11n not only can be applicable under the mobile networking architecture, but also provide a valuable reference for the mobile wireless broadband industry.
