When designing an outdoor mesh network to cover several sports fields, the core of the network is typically located in a building at the entrance of the sports complex. The Remote Access Point (RAP) is the device that provides backhaul connectivity to the wired network. The RAP is connected to one or more Mesh Access Points (MAPs) that provide wireless access to the users.
The type of antenna used with the RAP for backhaul connectivity depends on various factors such as the distance between the RAP and the MAPs, the environment, the frequency band used, and the desired coverage area. Based on the given options, the best choice for backhaul connectivity with the RAP is option C, a 5 GHz, 14-dBi patch antenna.
The 5 GHz frequency band is typically used for backhaul connectivity because it offers more bandwidth and less interference than the 2.4 GHz frequency band. The 14-dBi gain of the antenna provides directional coverage, which is ideal for point-to-point or point-to-multipoint backhaul connectivity over long distances. The patch antenna has a narrow beamwidth, which helps to reduce interference from other sources and improve the signal-to-noise ratio.
Option A, a 5 GHz, 8-dBi omnidirectional antenna, is not the best choice because it provides less gain and less directional coverage than option C. The omnidirectional pattern would also result in more interference from other sources, reducing the signal quality.
Option B, a 2.4 GHz, 8-dBi patch antenna, is not the best choice because it operates in the 2.4 GHz frequency band, which is more crowded and offers less bandwidth than the 5 GHz frequency band. It also provides less gain than option C, making it less suitable for long-distance backhaul connectivity.
Option D, a 2.4 GHz, 14-dBi omnidirectional antenna, is not the best choice because it operates in the 2.4 GHz frequency band and provides omnidirectional coverage, which is not ideal for backhaul connectivity over long distances. The 2.4 GHz frequency band is also more crowded and offers less bandwidth than the 5 GHz frequency band.
