We don’t intend to delve deeply to the two-way Radio, just a bird eye view. We’d want to accept the simple fact that it’s one of the developmental phases of the cell cell phone as we know it now especially in the form of the hand held Walkie Talkies. In other words it is a transceiver.
There are three kinds of this two-way Radio Player .
(1) The” genetic” mobile 2 -way Radio which gave birth to the contemporary Mobile Cell phone. It has the ability to receive and transmit simultaneously.
(2)The static two-way Radio that’s the basis of this modern Mobile BASE channels and the pivot where the modern day telephone system function. It might be pertinent to allow you to understand that Distance phoning by cell cell phones is only made possible by a community of cells. A cell is a BASE station (High rise Towers) with its policy area. For a mobile phone A to phone a distant telephone B, phone A must first join its nearest base station which in turn connect telephone B via its nearest base station. That is the reason these phones are known as CELL PHONES. Note that cell phones are two way Radios.
(3)The hand held portable two-way Radio more commonly referred to as the Walkie Talkies or Handie Talkies.
TYPES OF TWO WAY RADIOS.
Different systems, technologies and types are available.
1. The Family Radio Service version FRS: This model which is distinguished by a decrease power of half an hour can only support a maximum range of approximately 6miles in perfect conditions It is produced to transmit on a total of 14 stations which include 7 FRS channels and 7 shared FRS/GMRS channels.
2. The Radio has 22 channels and the signal can travel on either FRS or GMRS bands. However since customers want more stations and prefer the 22 channel Radio into the 14 channels, many radios now have all 22 FRS and GMRS channels available in producers’ response to market demand.
THE RANGE: The assortment of two way Radio denotes the maximum distance between two Radios for effective communication. A two way Radio of 5miles scope can only make effective communication if the space between the two communicating Radios is significantly less than 5miles. Therefore, the more complex the range, the better the radio. Regrettably however, the only means to know the range before buying as sellers are not likely to allow a physical test which might involve opening the package, would be to rely on the specification on the packing label. One wonders if the manufacturers are out to perform with their customers in view of the fact that what’s given is hardly correct. That such values are for ideal conditions may however be partly responsible. Achieving good line of sight free from blocking materials such as walls, trees, rock etc is desirable for successful reception. These are some of the necessary factors to achieve an perfect condition. All these can hardly be done in nature. The only option left to give us an notion of the Range is the ANTENNA.
THE ANTENNA: A good antenna won’t simply increase the range but also improve reception. Generally, the larger the antenna the better it’s But it not be too bogus to cause distress in our pockets. POWER: The higher the energy, the more complex the range. Even though a radio of half power could have a range of 6miles, that of between 1-2 electricity might have a selection of state 25miles.
AVAILABLE FEATURES: There are diverse features as far as we’ve got different producers and consumers. The fact is that if you want to have more features, then be ready to pay more. The following are some of the features common with contemporary two way Radios.
