DECT vs GSM: why you can not write off the radiotelephone
Technologies / / December 19, 2019
What it is, in fact, DECT and GSM and why compare them? These abbreviations denote communication standards. Without going into the history of the emergence and development of both standards, and use everyday terminology, DECT - it is a phone or a home office, with the base and the cordless handset. A GSM - it is a mobile phone. They are united by the absence of wires and the ability to communicate, without being tied to one place. But the differences in the work suggest that to completely replace one standard the other will not work.
Where better to hear
DECT - a guarantee that the interlocutor is perfectly audible. On quality voice DECT standard is difficult to find a competitor. It is connected to a data transmission technology by allocating time slot for communication subscriber unit and the base in the frequency range 1 880-1 900 MHz.
From a user perspective, this technology will emerge as the smooth transfer of speech without interruption, delay or interference. There are no "hard to hear", "repeat again" and similar pads. Of course, when you communicate with the subscriber, who uses a different communication standard, anything can happen. But inside the office, such as when talking on the corporate network, the problem will be eliminated.
What works steadily
Certainly, GSM «long range" standard lot more. DECT is guaranteed to support the excellent quality of the connection is only at a distance of a radius of 50 m. In general, this figure reaches up to 300 meters, but in favorable conditions, eg in the open field where you are unlikely to use phone.
But thanks to the installation of several stations can cover a large area. Housing will be enough of one base, and here in the office may require additional equipment in order to provide all employees with quality connection.
Limitation of coverage area - a natural board for stability. Lack of GSM-network to which you can not connect to the device, unfortunately, still remains an urgent problem. Operators are trying to fight for the density of the coating. A DECT connection makes it possible to be independent of similar troubles.
What is harder to crack
Security - one of the distinguishing features of the DECT standard. Listen to the conversation in this network is extremely difficult and costly.
The security is achieved through residency: the cordless handset is linked to one or more stations. Of the subscription and receive station authentication key. When establishing a connection with that key base will identify the phone, and any connection that could not "call the password" will be terminated. Built-in data encryption enhances protection and leaves almost no chance of unauthorized wiretaps.
What lasts longer on a single charge
The power consumption of the phone, too, is written in the pros. You can even say the whole day without taking the phone away from his ear: on-call some models of DECT-phones can work for almost a day. For any GSM-smartphone such indicators - Fiction.
With less impact on the body
Statements by scientists that mobile phones affect the body, it does not affect, succeed each other at high speed. No one really did not understand how bad every day to talk on the phone for hours.
While we expect any intelligible evidence of safety of mobile phones, it is better to play it safe and use home and office with devices whose signal level is much smaller and, therefore, affects the body with a minimum effect. Of course, there is in the DECT mean, standard phone signal is more powerful 10 mW due to the design features of the transmitters.
In some phones the optimal set of features
Do not think that DECT telephones can only receive calls or make calls. also appeared among them, smart phones, which are able to more. The ruler of one of the market leaders, the company PanasonicShows from which to choose.
For example, a decent DECT-communication can work as baby monitors, and even it can be connected to the ordinary smartphones iOS or Android. There is also a model with charging for the iPhone, but for now the mobile phone is charging, you can receive calls on the DECT-handset.
Well, the obvious things such as address book, caller ID, different melodies and color displays, also have the radiotelephone. They can not, as a heaped flagships, display videos and take photos. But of them that it is not required. The goal of a good DECT-system - it is a wholly-owned performance. And just it they provide.
