The equipment of processing Cell Phone Jammers needs to be cleaned

 The equipment of processing Cell Phone Jammers needs to be cleaned.
Net and marked with a vector network can be tested, we use the tracking generator with a spectrum analyzer. In the spectrum analyzer, connected to track the source, adjust the center frequency of the measured center frequency of the repeater, the repeater tone sweep width of the measured operating bandwidth, adjust the output level to track the source of the bridge test port has been reflected measuring the maximum input level repeater. To open / short reflection as a reference, measure the repeater antenna test port return loss values. Source output VSWR of the test has not resolved, only the output signal or power failure in the absence of state testing. Input VSWR test to consider the affordability of the repeater under test, if the duplexer isolator before, you can have in case of power failure test. The worker is carefully operating the machine of processing Cell Phone Jammers .
With noise figure meter to measure noise figure is very simple, but the GSM Channel Selective Repeater, because the bandwidth is much larger than the measured bandwidth of the instrument, so the test is very difficult, then simply use the manual test. Measured at maximum repeater gain, the noise source is switched on, power from the power meter reading on the Ph (mW or μW); the noise source is cut off from the power meter reading on the power Pc (mW or μW). If the measured frequency noise source excess noise ratio of ENR (dB), the measured noise figure of the repeater: NF = ENR - 10lg (Y-1) (5). The leaders are holding an important meeting concerning about Cell Phone Jammers .
Mobile Repeater seem simple, but otherwise, the key components of which requires or higher. Therefore, the proposed purchase by operators and manufacturers of quality certified testing agency qualified by the quality of the product, otherwise the results may not be ideal. The same coverage, the use of repeater lower investment. In the plain areas outside an omnidirectional base station covering a radius of 10km can be; a 4km-wide coverage to the repeater can have a radius; the coverage in terms of area, equivalent to about six a repeater station. Price of about six a repeater base station equipment of 80%. However, considering the room rental and decoration, AC-DC power supplies, air conditioning, transmission systems and circuits rent and other expenses, the cost is only about six repeater station on a 50% or less. The leaders are discussing the revise of working instruction of Cell Phone Jammers .
Coverage is more flexible. A base station is basically a circular cover, a number of repeater coverage can be organized into a variety of forms. As "a" type line, and can cover more than a dozen to a few kilometers of road. Can also be organized into the "L", "N" type and "M" type coverage, especially for mountain network. In the network initially, as the user less, poor investment returns can be replaced with a part of the repeater station. Developed after the user base is replaced, replace further down the repeater placed in the more marginal areas, such a step by step and rolling development. As the circuit does not require the construction of civil engineering and transport, building a network quickly. Some new rules are made for Cell Phone Jammers .
