radio is not our intention to more deeply into the radio in both directions, only a bird’s eye view view.We would accept that it is one of the stages of development of mobile phone, as we know it today, especially in the form hand-talkie Talkies.While a radio receiver (radio receiver) can receive broadcast content, only the two-way radio can also receive and transmit content.In other words, it is a transceiver.
are three forms of radio advertising in both directions.
(1) The “genetic” mobile in both directions, which has in modern phone.It Mobile Cell metamorphosiSed ability to receive and transmit simultaneously.
(2) The two-way radio, which is the basis of modern cell base stations and the pivot is fixed on which the opera. It may be relevant to modern telephone to inform you that the distance call mobile phones only possible through a network of cells. A cell is a base station (to towers) call with a cell phone cover area.For A to a remote phone B, phone A must first connect the base station B for the next turn you connect your phone through the nearest base is station.This, why these phones are called CELL PHONES.Note that mobile phones are also two-way radios. portable
(3) The hand-held radios commonly known as the Walkie Talkie Walkie Talkies /.
TYPES radios.
different systems, technologies and types are available.However, they are in two main forms, the FRS Family Radio Service and General Mobile Radio Service, GMRS models.
1.The FRS Family Radio Service: This model is supported characterizBed a power less than half a watt only a maximum range of about six miles under ideal conditions, it is to transfer a total of 14 channels including 7 channels of FRS and 7 shared FRS / GMRS channels.
2.General Mobile Radio Service, GMRS: Characterized by a higher power (usually between 1-2 watts BNA) This radio is designed for outdoor use. The radio has 22 channels and the signal can travel on both FRS and GMRS bands.However because consumers want more channels and prefer the radio network 22 to 14 channels that most radio stations now have the 22 FRS and GMRS channels available in the manufacturers respond to demand.
CHOOSE A two-way radio, you need to know.
THE BEACH: “The scope of a walkie talkie refers to the maximum distance between two radios communication.A effect from 5000 Talkie Walkie rangecan that communication is effective when the distance between two radio communication 5miles.Therefore lower, larger reach, the better the radio.Unfortunately but the only way to know around the area before you because vendors are not capable of a fitness test which could mean is to buy bulk pack to allow the information on the package called label.One may wonder whether the producers are not correct.That for their clients taking into account the fact that what is given is, these values play may be ideal for the conditions in part can responsible.Achieving good line of sight of obstructionist materials such as trees, walls, etc. Rock desirable for efficient recording. These are some of the factors necessary to achieve an ideal state. All these elements can hardly be achieved in the only option left to us nature.The give an idea of the bandwidth of the antenna is .
The antenna: a good antenna will not only increase the scope, but also to improve the reception. In general, the higher the antenna, the better is.However, most are not too wrong because of discomfort in our pockets.
POWER is: more power, the higher the radio range.While half of the electricity could be a series of six miles, which could be said of power between a series of 25 1-2 miles.
functions: There are so many different features that we have different manufacturers and consumers. The fact is that if you want more features, then be prepared to pay more.The following some common features with the modern radios are.
(1) Call and paging functions.

key lock (3) Headphone jack for mobile phones, etc.
