VIP Program eStadium Wireless Subteam Recommendation of North End Zone Concession Area Wireless Network For Bobby Dodd Stadium Last Revised October 20 2011 Adam Bommer Christopher Holmes Brian Kwak Gautam Meka Introduction The following proposal discusses two solutions for designing a wireless mesh network for Bobby Dodd Stadium A mesh network is necessary in the Bobby Dodd stadium to provide Wi Fi access to clients and to relay data from the cluster head of the sensor network The first option recycles more hardware already in the possession of the eStadium team and is more cost efficient to implement However it is a temporary solution and serves better as a test bed The second option requires more new hardware in the form of new router boards or custom PC s wireless cards and wireless embedded devices supplied by Texas Instruments The second option offers a longer life cycle and is more flexible for future modifications Mesh networks consist of a gateway and mesh nodes that operate on an IEEE 802 11a network The first mesh node receives the signal from the gateway and then relays the signal to the next node The throughput of a mesh network degrades by approximately half with each hop through the network Therefore no more than three hops are implemented for the mesh network designs Network Topology The North end zone concession stand area wireless network will include the backbone for the sensor network the backbo
