In recent years, the introduction of the "digital" two-way radios for two-way wireless communications market increased radio equipment and capabilities, but it also increases the purchasing / buying process selective choice, many customers find it difficult to understand and interpret. General managers, facilities managers, security officers and other key buyers has a particularly important responsibility is to ensure that they meet the selection of equipment available, the most suitable fit and function, in order to meet current and future needs. Of course there is a very important matter, with a cheap price to buy cheap stuff! This article aims to give a High Quality Two-Way Radio buyers about tips, help you buy a product to their preference.
The use of the term Analogue to describe two way radio communications usually means that the information being conveyed (what the user has spoken into the microphone) modulates the carrier signal (simply put it superimposes your voice upon the transmission on the stated 'carrier' frequency). The carrier signal travels through open space as an 'Electro-magnetic wave' and that wave reaches a certain distance or range depending on the frequency, the power and the intervening ground and environmental conditions. Sometimes in challenging conditions or over extended distances the signal becomes weak and difficult to hear. This is the limit of the range for that unit and the signal becomes very noisy and difficult to understand.
By contrast in Digital communications, the information being conveyed (again probably the users voice through a microphone) is converted into a stream of binary code. The modulation of the carrier signal on this occasion is limited to transmitting a series of 1's or 0's which are converted back into your voice at the receiving unit. In this instance, challenging distances and environmental conditions must stop the receiving unit being able to distinguish between a 1 or a 0 to affect the quality of the output. Hence, with digital two way radio you get a perfect reconstruction of the voice and crystal clear communication OR you start to lose complete words or even the whole transmission when the signal is lost.
"Digital era", compared to the two-way radio they substituted a similar device, its advantage lies in effective antennas, advanced electronic design and high quality production conditions. In addition, the real benefit is already used in the development of these digital units allow other digital products, including building management systems connect a simple, one output can automatically send text messages to inform a great team of facility applications, demand an air conditioning unit Note, or the output from the fire panel allows the staff aware of the existence of a fire and its location. It seems to be written on the wall of the analog two-way radio at the end, but it changes the speed will be determined by the market, no one can accurately predict there!
