Is the Wi-Fi working?

In stadiums, as well as other large public venues, when concentrations of mobile device users simultaneously try to access the network, cellular networks are insuffi cient for the demand. Operators ease the congestion by offl oading the bandwidths to complementary technologies, most often Wi-Fi. In response to the ever-increasing popularity of mobile devices, stadiums are now constructing high density networks to ensure adequate capacity (higher data rates). High density networks are created by mapping users into smaller radio frequency (RF) cells of operation. To generate these narrower cells, access points are connected to high density narrow-band antennas that minimize channel-to-channel interference, which is the most significant cause of limited performance in a Wi-Fi network. With fewer users per access point (AP), the amount of bandwidth per user is increased and spectral capacity is maximized. Several essential design variables must be considered when designing a high density network. Total coverage area, channel utilization, frequency of reuse, interference, signal strength, spectral capacity, and regulatory requirements are all factors affecting the network. After the AP is selected, a site survey is performed. A wireless site survey, sometimes called an RF site survey, is the process of planning and designing a wireless network that will deliver the required wireless coverage, data rates, network capacity, roaming capability, and quality of service.
