construction delays, the FCC violations, penalties, and costly, all possible outcomes for the construction of wireless tower without adequate protection of the nearby AM station.
If you build a tower or modified within 3 miles of a site management (multi-tower) or a non-oriented one kilometers (Single-tower) FCC rules require broadcasters to protect the site model AM.
The AM station must be notified prior to any construction orChange happens. Supporters of the building they need to do this in the stations and measures to protect the model of AM station antenna. A vacuum system may be needed to ensure proper implementation of the matrix AM station. If a detuning system is necessary for the ongoing maintenance and operation of the system is necessary.
The interaction between the AM antenna systems and towers and other wireless phones is most often the density of cell sites increased. This interaction isusually independent of the frequencies used on the wireless tower, and applies only to the function of the proposed tower on AM frequencies (540 - 1710 kHz).
If the cell tower will receive a significant portion of a wavelength in the AM band, the mutual coupling occurs between a new tower and the tower AM. This mutual coupling induced AM RF power in the mobile tower, then some of this energy is re-radiate AM. Thus, the wireless tower actually another tower inAM station, the system does not change, radiation FCC license.
Other structures such as power lines, water tanks, cranes, oil rigs and other structures, permanent or temporary can cause problems for AM stations. The disorder can cause loss of coverage, off-air time, and interference with other stations. Furthermore, lesions cause FCC regulators, these disorders in substantial economic losses due to affected AM stations.
In addition to the AM modelThe disorder can create structures of non-ionizing radiation (RF) security issues. These issues must be examined thoroughly for the safety of personnel.
Some of the structures, the problems for the operations of AM station because steel transmission towers, tanks, oil wells, chimneys, tall buildings and bridges. Structures that are more than three kilometers from the AM station is not usually a cause for concern. The effects are in the area must be evaluated on the basisCharacteristics of the AM station, and physical and electrical properties of the structure to interfere. A technical investigation should be done before work on site. That includes measures to pre-construction at the basic level of performance information to the constructor of the document after AM that could have influenced the models AM protect.
The FCC has a longstanding principle that licensees AM impact of the new environment must be protected from radiationStructures. In a recent public announcement on this issue, the FCC reminded others of their responsibility to protect existing dealers AM:
"The (FCC) has a number of complaints received from AM transmitters on the building ... is clearly close to their bodies ... PM Commission policy. Whether the imposition of special conditions or by operation of law (the manufacturer) of a new plant is required to take all necessary measures to correct, including the financial burdeninterference problems by new ... Construction. "
"The (manufacturer) is responsible for installation and ongoing maintenance of detuning apparatus ..."
The FCC also established a series of stages of engineering structures that are necessary for the performance of protection of AM station has been reached, and the requirements for temporary operations, which are coordinated with the AM station must. The FCC ruled that the obligation of protection is universally applicableBehalf of its licensees, even if this note was addressed specifically to the common carrier licensees.
Can be selected for important financial and legal burden on a manufacturer AM Models can ignore safety requirements as they cause economic damage to the AM station.
