MOBILE FOR THE DRIVER: WHAT IS INCLUDED?
Everyone’s needs are different: some use a mobile phone once or twice a day, and even less often, others spend a day or two on wheels and their phone does not stop talking. We’ll talk about how to choose “your” set of auto accessories.
FREEDOM OF MOVEMENT
In Russia, as in most developed countries of the world, it is forbidden to drive a car while holding a phone in your hand (the corresponding law was adopted on April 1, 2001). The simplest solution is the hands free kit. The device consists of a microphone, earphone (headphone) and a call answer button. It is not required to specifically mount it in the car; it connects directly to the phone. But we do not recommend buying hands free without trying on: after all, the device is fixed, as a rule, on the ear or in the auricle, and they are all different. There are stereo headphones, but they are not suitable for a car - the driver should hear not only a telephone conversation, but also “road” sounds. More "advanced" devices automatically reduce the volume of the radio during a call, but to implement this function, the radio must support this mode. Hands free is not tied directly to the car, so it can be used on the street, in the office, and at home. Prices - from $ 10.
Those who think that carrying a bundle of wires around themselves is uncomfortable or unaesthetic can do without them by buying hands free with a bluetooth interface (ZR, 2001, No. 11). The kit includes the actual headset (earphone + microphone) with a small battery, a mains charger and often a set of adapters for sockets of different standards and a case. Modern headsets (for example, Bluetake VT400) are almost weightless (only 10 g) and very economical: the battery lasts for a three-hour conversation or for several days in the call standby mode. Communication between the “earpiece” and the telephone is supported on high-frequency (2.4–2.48 GHz) radio channels. Range - up to 10 m (of course, obstacles reduce it). Prices for bluetooth headsets start at $ 160. In the lines of all major manufacturers there are phones that support this standard. Prices for such devices start at $ 250 (for example, Nokia 6310).
Another undoubted (and for many, most important) advantage of bluetooth is its compatibility with any devices (including computer boards, printers, etc.) that support this standard. When changing the phone, you don’t have to buy a new headset for it, and this is a direct savings.
Handsfree kits consist of a speaker, a remote microphone, a phone holder with a recharging function. Installing such a kit in a car has many nuances, it is better to entrust it to professionals. Sometimes the conversation is broadcast through the car’s standard speakers (the sound of the radio is muted for this time). The main advantage of the “speakerphone” is that you don’t need to wear a headset (many cannot get used to the load on the ear). But the kit, as a rule, is tied to a specific phone model (and, of course, to one car). With the new handset he will remain out of work. However, there are already similar devices with bluetooth, they are devoid of this drawback. Prices - from $ 220, installation - another $ 50-100.
ON A PROMINENT PLACE
With the advent of headsets, the phone holder in the car became formally not needed. But leaving the cellphone in your pocket is still not worth it. Firstly, some simple models of headsets do not report a call, and you may not feel a vibrating alert through a sheepskin coat. Secondly, when driving a car accidental keystrokes on the keyboard is difficult to avoid. And finally, the radiation power of the antenna in the car as a whole is higher than in the open area, which is not at all good for the body.
Holders can be divided into “grips” and “magnets”. The former are convenient in that they can hold the phone in a case, the latter are good for versatility - they will magnetize almost any model for the battery (for the others, a magnetic plate is included). Cheap ($ 5–10) are usually attached to the dashboard on the included self-adhesive “Velcro” included in the kit: it’s sometimes impossible to quickly tear it off (when selling a car). Holders from expensive sets are usually mounted on special perforated plates, they are inserted into the slots between the panels and fixed from the inside, removing the ashtray or radio. After dismantling, no traces remain.
I DO NOT HEAR YOU
The metal body of the car prevents the propagation of radio waves, so the antennas of a regular mobile phone for reliable communication, especially outside the city, are not enough. When choosing an external car antenna, don’t make it cheaper - a fake can not only be inefficient, but also burn the phone: with a poorly tuned circuit (high standing wave coefficient), the energy will not be emitted, but will return to the output stage of the transmitter. In this case, you should not count on warranty repairs, especially if you honestly tell the receiver the “medical history”.
In addition, pay attention to the working range of the antenna - it must coincide with the one in which the phone works. Let's say the 1900 MHz antenna is not suitable for the GSM1800. The problem is that for the GSM 900 standard, popular in Western Europe, there are practically no branded antennas - there the “cells” cover the territory so densely that there are practically no reception areas. Therefore, you have to choose from Chinese, Czech, Polish and Baltic. The most common antennas are whip antennas. After connecting such an antenna to the phone, 1-2 “cubes” should be added on the scale, which corresponds to a gain of 1-3 dB.
According to the mounting method, the antennas are divided into mortise, magnetic and self-adhesive. The former are often included in hands-free kits and built-in phones (more about them later). The main drawback is that you have to drill the roof. Such an antenna is uninteresting to thieves - you won’t be able to remove it quickly and accurately. But it gives an occasion to ask about the "filling" of the car - it is better not to leave it unattended.
The magnetic antenna is devoid of this drawback: quickly set, quickly removed. Yes, and use it in the city is optional. Its minus is a cable dangling in the cabin. And in heavy rain, water can seep under it under the seals.
Interesting antennas glued to the rear window. In this case, the counterpart with the cable is glued from the inside (you do not need to drill the glass). Disadvantages - the same as the mortise antenna, advantage - the roof is not damaged.
Recall that the “pins” are better placed vertically - this is exactly the polarization of the signal from the translator. The price of external antennas is from $ 10-15.
When equipping a personal car, you should take a closer look at the built-in phones (for example, Nokia 6090). They provide a full range of service functions (speakerphone, “private conversation”, recharging the battery), and in addition, the output power of the signal from them can reach 8 watts (with ordinary phones a maximum of 2–4 watts). The price of Nokia 6090 is about $ 500.
IN ONE BOTTLE
A mobile phone is no longer just a means of communication: it can catch the radio, play music, take photos and even shoot videos. But such functions are only in modern (and relatively expensive) models. However, prefixes for phones are also available.
Passengers sleepy, but you don’t want to turn off your favorite wave? Just for such cases, an FM tuner is useful. Its headset allows you to listen to the radio and answer calls. And for music lovers of our choice, we recommend an MP3 prefix. One flash card will replace a whole set of cassettes or audio CDs. You look, and the cabin will become more spacious.
