The technology is identical to satellite TV, and this phenomenon is familiar to anyone who has a misaligned or incorrectly sized dish on their home! Microwave energy does not penetrate solid objects, and thus there must be a clear line of sight between the transmitter and the receiver. This factor tends to limit the use of microwave to short range, unless it is possible to locate the equipment at both ends of the system on top of high structures. Alternatively the signal would propagate well across flat expanses, however there are not many of these in the UK!
One method of testing the signal quality capability is to pass a specific test signal along the cable and measure it at the other end. The test signal could be a sync pulse and black and white test bar pattern derived from a video signal generator. Alternatively a ‘pulse and bar’ generator may be used. 2). The measuring equipment at the output end of the cable on which the waveform is monitored would be an oscilloscope (for instruction on how to set up an oscilloscope to observe a video signal, see Chapter 12).
Well, that is the theory. There are some practical considerations that should be made. First of all we must remember that digital video signals require a lot of bandwidth, even when compression is used (see Chapter 5), so there must be sufficient bandwidth in the system to handle the data. Then there is the issue of available bandwidth because, if the IT system is already working almost to capacity, then the addition of just one camera may well take it over the top, resulting in some devices on the network becoming excluded; and it may not be 24 Closed Circuit Television the camera that goes off-line, but perhaps other devices on the network such as printers, scanners, or even things like air conditioning if the building management system is also reliant on the Ethernet network.
