Análisis de desempeño del IEEE802.11 para la conectividad de zonas rurales de Colombia

In this paper, we present the performance characteristics of IEEE802.11 standard in point to point reaching over rural sites in Colombia. To explain this performance is first should be carried out a detailed description of the behavior of the physical and MAC layer in the deployment of long-range networks, this is done by analyzing the existing regulation for maximum equivalent isotropic radiated power in the ISM band, the propagation losses, the reception level of commercial Wi-Fi radios, the frame error rate and considering the parameters DIFS, and ACKTimeout SLOTTIME that are part of medium access control affect the implementation of radio links of several kilometers. Following from this theoretical models in the literature and one proposed by the authors calculate the saturated throughput UDP unidirectional and bidirectional function of the distance considering the different transmission speeds; After a couple of prototype autonomous Wi-Fi communication photovoltaic powered laboratory designed and built, a group performed experimental measurements of saturated UDP throughput in point to point links between Bucaramanga and rural sites surrounding metropolitan area in the range of 0-10.4 km distances, measurements are performed using the iperf traffic generator sending UDP packets of unidirectional and bidirectional, then the measurements are compared with those obtained theoretically.
