At the moment, breakthroughs in wireless technologies have led to the extreme popularity of radiotelephones. Now these technologies have brought wireless communication to an undeniable level. In this article I would like to tell you about some classification of modern household radio teleshops and some advice on their operation. Now radio telesphones are classified according to such features as the range of action, the operating frequency range and additional phones.
According to the range of actions, radio telegons are divided into three types:
radio -telegraphs with communication range within the apartment (from 10 to 30 meters);
radio -telegraphs with communication range within the radius of the apartment, as well as in the courtyard of the house (from 100 to 300 meters);
Radio telegraphs with a long -distance communication radius of more than 1 kilometer.
All new radiotelephones have the opportunity to work in four wave ranges: this is from 30 to 39 Meghartz, 300 megagez, 900 and 1800 megagez.
Service functions
Service functions that are in the radiotelephone can be divided by the following criteria:
There is an indicator on the tube (very convenient during the number set);
there is a cassette or digital answering machine (needed for each user);
The buttons are highlighted in the dark (quite convenient function);
the possibility of intercom and the presence of buttons with numbers at the base station (this is when you can talk between the base and the tube);
there is an option to connect other tubes.
Radio telegraph companies
I will try to provide the general characteristics of radiotelephones for the most common companies that produce them.
The most famous and leading manufacturer of radiotelephones is undoubtedly Panasonic. The phones of this brand became popular due to their excellent communication quality, a large range of models, and quite cheap prices. They produce radiotelephones in almost all working ranges, as well as in the DECT standard. If you compare Panasonic phones with similar models, they have a much smaller radius of reception than competitors. Sanyo also produces radiotelephones, but they are inferior in quality, assortment and reliability to the models of the previous company. This company also produces radiotelephones of almost all reception ranges. But in the range of 900 Meghartz, this company has undeniably the most powerful Sanyo T-928 model.
Siemens is considered the creator of fashion among the phones of the DECT standard. The company provides a wide selection of radiotelephones, as well as additional equipment for them from the simplest and most budget models and ending with office mini—ATS, as well as devices for creating a micro-combat network.
