 considered. Construction may be subject to local planning conditions such as improving site access, providing an equipment shed and lighting, etc. Planning authorities may also require a waiver to allow future use of a new tower by other operators at a reasonable rent. Soil sampling may be required depending on the design of tower footings - the structural engineer involved in tower design will need to advise on this requirement. Physical BS antenna deployment - Positioning antennas, waterproof cables and securing all connections with the aim of minimising future maintenance costs. Subscriber Deployment Subscriber agreement - A subscriber agreement will be required to define the terms and conditions of the service being provided. Besides the Implementing Wireless MANs obvious aspects such as cost and the duration of the contract, the agreement should cover any quality of service guarantees, liabilities, termination conditions, etc. An Internet search will turn up a wide variety of sample subscriber agreements, including many for wireless ISPs, although once again it is recommended to take legal advice to ensure that agreements comply with local laws. Subscriber site survey - Once the BS is installed, a simple site survey can be conducted at each new subscriber site by using the intended CPE antenna and receiver mounted on a light pole to lift the antenna to the intended installation point, with a cable length comparable to that required to run back to the subscribers computer location. A preliminary link budget calculation, followed by this type of quick site survey, can assure the quality of the wireless link and help prevent repeat visits in the event of performance problems. Customer premises equipment installation - If ease and speed of installation have been considered when selecting equipment, CPE installation can be prevented from consuming too much time and money as the network grows. Customer premises equipment grounding - Effective CPE grounding is important for three reasons, to make sure the antenna
