Towers and Alternative Structures wireless Colocation

As wireless networks mature, the desire for wireless service providers to establish additional cell site base stations has been driven by several factors.

Already serving a geographic area where the service provider is not required to provide coverage. Also, "dead spots" or areas where the signals are weak in the filling. In addition, the channel bandwidth or spectrum reuse to allow for a large number of clients and support for emerging technologies meet the requirements of high speed.

Early in the development of wireless cellular towers owned by the carrier and allow them to other users, especially competitors, the towers were not considered. However, increased in the towers, the term colocation wireless has become a common term in the dictionary. Was caused by many reasons the acceptance of wireless colocation. One other uses for wireless carriers and their infrastructure investment saw an opportunity to reduce free cash. The second tower owners to secure tenants on each tower is needed to complete the return on investment goals.

Seeking out the first structures to the new base station sites are looking for effective strategies. While this helps to solve the above problems, it creates new challenges. Often the network RF design have changed several times during the site selection process. Sometimes, the structure search circle center and / or height away from the system that was used to plan, will not support the Base Station Antennas. The optimal coverage is desired that can result in the shortest possible time. Capacity of existing structures to wind loading and weight of lines and antennas to support requirements should be determined. This requires a structural analysis, adding to the cost of the site. When sharing a site with other emitters, intervention is an idea.

While it may seem complex regulatory compliance at a wireless colocation site, the opposite is often the case. For example, non-ionizing FCC and OSHA regulations regarding human exposure to RF energy requires that all emitters, even a site for others to be considered.More local jurisdictions are required to submit documents the fact that the site is in compliance with all rules and regulations attest. Many require third party review of compliance activities.

Looking for existing structures to drive the first time "outside the box" solution that makes up for discussion in the network has never been produced. Water tanks, smoke stacks, church steeples and bell towers are acceptable to most carriers. Power line towers and AM, FM and TV broadcast towers are many colocating. Each of these presents unique set of challenging ideas, they all viable candidate for wireless colocation. With proper planning and design, have all been used successfully to support wireless base stations.

Colocating on an existing structure is a good solution for many sites, however, there are some situations where a new tower is needed. Jurisdiction in cases that challenge an existing structure needs to convince officials that a new tower and will work. Zoning and planning are pushing an increasing number of groups that need a new tower to be a third party appraisal.
