lization, frequency of reuse, interference, signal strength, spectral
capacity, and regulatory requirements are all factors affecting the
network. Designing the high density network begins with a comprehensive analysis of existing client infrastructure capabilities,
the number of users/clients, the number of Wi-Fi enabled devices
per user, the user application requirements, the physical facility
characteristics, and a careful determination of the appropriate
number and placement of access points.
To design a high density network for a stadium, first determine
the overall capacity necessary by estimating the number of clients
(seats in the stadium) and client devices that will be supported.
Next, determine the client device capabilities and the application
throughput requirements. Typical application throughput requirements for users in stadiums include accessing the network to send
email, visit social media sites, and share photos and videos.
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 (QoS). The survey usually involves a site visit by the surveyor to understand the RF behavior,
discover RF coverage areas, test for RF interference, and identify optimum installation locations for APs and antennas. This
requires analysis of building floor plans, inspection of the facility,
and use of site survey tools. After initial AP and antenna installation, testing is performed and adjustments are made to refine the
design for the highest capacity per user with the least amount of
