Objective
P2 Wireless Technologies Limited -- Confidential
• Fung Kai school group wants to install a video surveillance network in their 5 school campuses and surrounding areas to provide safe campus to students
• They will deploy a wireless mesh network solution as backbone to connect all the surveillance cameras
• The wireless mesh network needs to be resilient with self-recovery functionality
• The throughput should be large enough to support all the cameras now and expansion in future
Objective
P2 Wireless Technologies Limited -- Confidential
• The 5 school campuses cover a very large area of 100,000 sq. m
• There is no cabling between the school campuses
• The exact site location may change often at the last minute due to changing user requirement in camera location
• There are NLOS blockage between the school building rooftops
• Need to deploy the network in short time to minimize the influence to teaching and activities

• A 5-hop wireless mesh ring is built on rooftops of 4 school campuses as backbone using X20
• Site 5 is a relay-site to overcome the non-line-of-sight blockage between sites 4 and 6
• 6 cameras are connected to the X20 initially • Total mesh ring throughput is designed to be 300 Mbps
UDP, enough for future expansion up to 20 cameras
• Cameras can be added anywhere at AP along the mesh ring
• Mesh link redundancy and auto-recovery features are incorporated for highly resilient network structure
• Gigabit PoE+ 4-port switch will be used to power both AP and camera. Extra port for easy camera expansion
