How to choose a cell phone? From a technical point of view.

One thing unites them all: they describe the approach to business from the point of view of the consumer, the beauty of the menu and the availability of cameras and camcorders, without affecting the technical essence.

Tell me, do you need a fancy phone that can not reach you during rush hour? I think this situation is not enough for anyone, but in fact this happens all the time.

Therefore, later we will discuss how to choose a phone for its technical characteristics.

The first thing you should pay attention to is codec support: HR, FR, eFR, AMR. Of the entire list, we are most interested in the first.

During peak hours, when the load on the network increases, it is on the first codec (HR) that most base stations work. FR utilization percentage is extremely low. As for the last codec, it still does not work everywhere, and its presence will be a weighty, but not critical, advantage. Attempting to call from a mobile phone that does not support the HR codec during rush hour will lead to a deplorable result: "The network is busy."

Unfortunately, finding information about the supporting codec in the store is quite problematic. Not least because of the rather low-skilled staff. They are more specialized in external phone features and are not always aware of technical indicators. Therefore, it is better to look for such information on the Internet.

Many pay attention to battery life. In fact, this is quite a mythical indicator. To understand the criteria by which manufacturers evaluate this time is almost impossible. Quite common cases when a cell phone battery sits four hours after fully charging instead of the two hundred and forty put. It's about standby. Of course, you can pay attention to this indicator, only you should not trust him.

Oddly enough, you need to look at frequency range work of this phone. There are several main ones: 900,1800,1900 and UMTS (better known as 3G). In fact, there are more. It happens that the phone supports only 1800 or 900/1900. There are two ranges in our country: 900 and 1800, which is exactly what your mobile device should support. Watching for the beautiful 3G abbreviation does not make sense yet, in any case, if you don’t often travel to Europe.

Mobile Class also quite substantial. Although now there are mainly 4 classes, but there are exceptions. The higher the class of the mobile device, the worse it will receive the signal. Below is also not worth taking, since the maximum output power in the cellular communication system for mobile devices does not exceed 2 watts. The optimal classes are 4 in GSM 900 and 1 in GSM 1800.

I hope these small technical tips will help you find the right mobile device and avoid unnecessary cheating prices for unnecessary functions, such as 3G.

And it’s also worth deciding for yourself what a mobile device is for you: a communication device or a show. If the means of communication, which should always work, then you need to use the tips above, but if you are not particularly interested in the connection, then you can listen to the specialists of mobile phone retail sales.
