Wired/wireless data transmission systems


wired wireless transmission data


Proper wireless and wired building network design cannot be restricted to simply assessing the number of pieces of equipment and their installation positions, but must also include an initial analysis of the bandwidth required.

The required bandwidth is the result of specific scaling criteria that encompass, amongst other factors, the number of users, the estimated number of people accessing the network at the same time and the type of network usage (email, surfing the web, IP voiceovers, video streaming, etc.), since different applications require the availability of different bandwidths.

In the case of a Wi-Fi network, a number of other factors contribute to the effective operation of the network itself: the transmission power, the aerial gain, the minimum signal level received and cable loss, all of which are elements that cannot be overlooked during the design phase.

Lastly, it is necessary to remember that the radio waves of a Wi-Fi network do not stop at the edge of the property, meaning that protection against fraudulent access to a Wi-Fi network is an absolute priority during the design phase, given that a malicious user could download sensitive data from the company’s information system without transmitting even a single packet, then going on to use the content to launch more sophisticated attacks on the system.
