How To Choose Your Walkie Talkie Radio

---

We all created home-made walkie talkie radios when we were young, out of plastic cups and string. Pretending to communicate to each other via the power of fibre led to endless hours of fun and laughter. Luckily, as we got older and discovered a little of the science behind telecommunications, we realise it takes a little more than string to converse with others in other locations. We realise that the grown up version of the walkie talkie radio is in fact a highly beneficial tool used throughout all society, from businesses, to military and also day to day consumers.




As opposed to the broken cups we used to shout in to, communication via the walkie talkie radio involves speaking into the mouthpiece of a small hand-held radio that can fit in the palm of your hand. By holding down a small button while speaking, the words are instantly transmitted to the receiver via their walkie talkie radio. Release the button when you've finished speaking and hear the received response transmitted back to you.




You can buy two different types of walkie talkie radio licensed and unlicensed. Licensed walkie talkies have a specific radio frequency in which the communications are transmitted across. The frequency is isolated and will only be used by one set users at one time. In contrast, unlicensed varieties are what you would normally purchase in most electronic stores. While these are a more cost effective option, unlicensed walkie talkie radios do not have a designated frequency and as a result, can suffer with cross communication from other users.




Depending on how you plan on using your walkie talkie radio will determine the type you will need to purchase. If your communication is just for leisure purposes, such as hiking or skiing, you could consider investing in an unlicensed version. The main purposes of walkie talkie radios on a ski holiday for example, are to help you keep in touch with others and to protect your safety, should you have an accident on the mountain. For these purposes, an unlicensed model would be more than sufficient, especially considering you will only be using it for a few weeks while on holiday.




If however, you need your walkie talkie radio for a more prolonged period for business purposes, you would probably want to consider a licensed model. Security guards and taxi drivers for example would need to function on their own frequency it wouldn't be appropriate (or safe for security guards) to be sharing a frequency with others. There are options to use a voice scrambler if you are looking to keep conversations private or sub channels that allow for private communications, within an existing network.




Aside from being licensed or unlicensed, the coverage available with walkie talkie radios is likely to be another contributing factor when choosing your model. Most radios will cover an area of around about two miles radius however if you require distance in excess of five miles, you should definitely be looking to invest in a licensed radio.




Also, if you plan on having a number of different operators using the walkie talkie radios, you will also need to ensure that a compatibility system is available. This allows communication to take place between different users without any interference.




While the boom of the mobile phone has certainly taken the consumer market by storm in terms of communication, there are many situations where the phone simply doesn't even compare to the walkie talkie radio in terms of its capabilities. Not only do walkie talkie radios not go out of signal range like mobile phones, you also don't have to worry about running out of credit at a crucial moment or paying for calls. Communication is instant and in situations concerning safety and security, these features could be lifesaving.

Video Reviews Embrace Our Thirst For Information

---

It's not quite 1984 yet, in an Orwellian sense, not chronologically speaking, but technology is certainly advancing to a degree where the term science faction is permeating the development of some of the gadgets and gizmos that are out on the market. In this category you could expect to find a spherical hardwood wireless computer mouse, a photo frame that is a printer and stereo in one and a mobile phone that costs a grand and a half that functions as a computer, sat nav, camera, and lo and behold - as a telephone.




To keep up with the latest offerings from the science faction factory, we are turning to high tech technology for world news and product reviews. For any of you that are familiar with Warren Ellis's Transmetropolitan, we are living in a similar eerie era of semi science fiction. Information is no longer reaching the general public in the pages of a broadsheet, or even over the airwaves of a British Broadcasting Corporation channel. Today's news, views and reviews are being received by satellite and cable technology that outputs RSS newsfeeds and podcasts through mobile phone technology and the internet.




Video reviews are currently the favoured format for advertising and marketing as well as being used to full effect in online social networking. This choice of presentation has the advantage of being up loadable to mobile phones, media players and computers for a quick hit at home or on the move. The medium of video reviews is suited to a throwaway infomercial style of presentation, and the beauty of it is that being able to produce one is within the reach of anyone that can press a button.




Mobile phones for example are capable of recording video footage, and although the quality is generally pretty low, it is good enough to upload to a blog or you tube account. Often the content is the filmmaker's commentary or opinion on a subject or an event. A quick scan of the search pages on the internet will invariably provide video footage as a way of presenting whatever information it is you are after. The reason for this is the accessibility of the medium of video recording and the flexibility of platforms for presentation through digital netwrorks.




Video reviews on topics as diverse as how to cook the perfect pancake to what a person really thinks of the latest x-box release are available to the information hungry public. Often, the video format is used to spread news of a natural disaster or a compromising political situation. In this light, the ability to create a video review means that everyone that owns a mobile phone is a potential journalist or filmmaker.




This has invariably had a knock on effect in the publishing industry and journalism in particular. In an era that is now rapidly coming to a close, the average reporter or journalist was privy to information that others could not seek out, and the definite advantage was in the way the information would be presented. A journalist would have to be either employed by a newspaper to be able to publish material, or have access to a broadcast team to appear on the television. The new era we find ourselves in has taken the upper hand away from the professionals, and it seems that the public enjoy a more accessible and varied view of the world on every topic through the medium of video news and reviews.
