Walkie Talkies: Advantages over mobile phones
Many users will ask, before the advancement of mobile phone technology, what is the point of buying a Walkie Talkie. The reality is that the use of portable radios has a great number of advantages over phones, especially for professional use. In addition, both telecommunications systems can be perfectly integrated, allowing their use in the most diverse circumstances.
Price.With walkies there are no fees and you do not have to pay for calls.
As they are radio waves, the walkies can work in any type of environment, even in areas where the mobile signal does not arrive.
Simultaneous communication. With a Walkie Talkie it is possible to communicate in a single call with several users at once, something impossible on a mobile phone.
Simpler handling than a mobile phone. It is only necessary to search for a channel and start talking.
Autonomy. The batteries are long lasting and last much longer without recharging.
They are tougher, stronger and more durable devices since they are designed to work in the most adverse conditions.
You only need to press a key and start talking (Push to Talk) without dialing any number.
Features of a Walkie Talkie
Among the different extra features offered by a walkie talkie we find: Hands free function. Scanner (scan function). Automatically explore the least congested channels to communicate. Emergency call. It is activated automatically in case of emergency through a programmable button. Man down. Man to Earth. When the equipment reaches a certain degree of inclination, the walkie enters emergency mode and emits a signal in case the user has suffered an accident. Very used in construction. Individual calls / messages on devices with display and keypad.
What Walkie Talkie to buy?
The technology of the Walkie Talkies advances faster and faster and there are all kinds and conditions. Therefore, when choosing a device, you must first ask yourself some questions to find the type of equipment that best suits your needs.
PMR Walkie without a license or Professional Walkies with a license When buying a walkie, you must choose between PMR 446 Walkie Talkies without a license (Personal Mobile Radio, 446 MHz) or licensed professional walkies.
Walkie Talkies Without PMR License They are perfect for leisure activities (excursions, hunting ...) but also for some professional sectors such as shops, restaurants, events or discos. These devices use the PMR446 frequency, which allows free use without paying anything for it. In addition, they are very simple to use. They just have to be loaded and look for some free channel to talk. Other features:
- They have 8 channels. - Very low transmission power - Little reach (between 4 and 10 kilometers without obstacles). - Within the range of PMR Walkies, Tecnitrán offers the Motorola CLP446, Motorola XT460, Kenwood PKT-23, Kenwood TK-3401D / TK3501 and Vertex VX241.
Licensed Walkie Talkies Professionals - They require the payment of a fee, which usually costs around 175 euros, to get a license with a duration of 5 years. - This license allows the use of a frequency exclusively for us. - They are the ones chosen for professional use due to their large number of functionalities. - Greater privacy in communications, since it uses its own frequency, which makes communications more secure against the interference of third parties. - The communication is also clearer, without interference and with less noise. - They have longer batteries than the PMR walkies. - They also have more call channels (usually 16, but some reach up to 1000 channels), which allows you to communicate with more people. - Greater range and greater wave power, which helps overcome obstacles such as forests, thick walls or buildings.
Walkie Talkies UHF or VHF Where will I use my walkie? You should also look at the type of walkie talkie frequency. There are two: UHF and VHF. It is vital that you be careful with this, especially if you are going to use your equipment with other devices, since both types of frequency are not compatible with each other.Most models, however, allow operation in both of them at your choice.
VHF or Very Hight Frecuency.
This frequency range has a very long wavelength, allowing greater range. They are ideal for use in large areas, in the open and without obstacles.
UHF or Ultra High Frecuency.
They are shorter and shorter-range waves, but much more powerful when it comes to overcoming obstacles (walls, efficiency ...), so they are recommended when the walkie is to be used in urban or interior areas.
Lithium or nickel battery walkie: autonomy Nickel batteries. Last up to 12 hours without charging. Lithium batteries They are much more durable (20 hours) but also more expensive. Printed batteries Automatic reconditioning. It is a new type of Motorola battery that, when connected to a charger, communicates with it to report its status and thus be able to take it to the optimum operating point, reconditioning parameters if necessary.
Digital Walkie Talkies or Analog Walkies The world of Walkie Talkies is immersed in full digital transformation.It is an inevitable process that offers multiple advantages over the previous analog system.
More sound quality.
The signal of the digital walkies is more constant and stable. Do not get lost in the distance, which suffers less interference and the sound quality is higher.They have multiple functionalities , such as data transfer, text messages, GPS or background noise inhibition.
Security and privacy
They use less congested bandwidth and also have multiple coding possibilities, so they are ideal when you need maximum confidentiality in communications. To achieve this, analog systems had to encrypt communications, but new digital equipment (such as the MtoTRBO series, the Motorola Walkies digital range) has two forms of serial encryption: with security key or through software ( which also protects against computer attacks).
If you already have a fleet of analog walkies, most digital equipment can also work in this mode, allowing the analog-digital transition to be less traumatic, more progressive and cheaper.
More calls per channel.
Digital Walkie Talkies allow up to two simultaneous communications per frequency (analogue only one) exponentially increasing the number of users with whom to communicate and lowering frequency costs.
A higher battery time.
Most have lithium batteries and we can choose between Impres batteries and chargers.When choosing your professional Walkie Talkies, you must also take into account characteristics that indicate your degree of resistance and robustness, measurable by the degrees of IP protection and the ATEX protocol.
Degrees of IP Protection.
Walkies Ingress Protection- Measure the resistance of the device against water (submersible walkies) and dust. The information is given with a figure consisting of two numbers. First number: Measures the level of resistance against the entry of solids (mainly dust). The higher the number, the greater the degree of resistance it will have. This figure goes from 3 to 6. The 3 indicates degree of resistance to solid objects of more than 2.5 mm. 4 to solid objects of more than 1mm. 5 indicates dust resistance. The 6 is the tallest of all, and points to a dustproof Walkie Talkie. Second number: Measures the level of resistance against the entry of liquids. Like the first number, the higher the resistance it will show when immersed in water. 2 indicates splash resistance, 3 indicates water mist and sprays. The 4 to heavy rains and bad weather in general and the 5 to jets of water under pressure. From 6 we started talking about Submersible Walkie Talkies, but for different periods of time. Grade 6 resist for a few seconds in the water. Grade 7 up to 30 minutes. And those of grade 8 can be for a long time immersed in liquids without being damaged. No resistance: When the walkie does not show any degree of resistance to dust or water, it will show this figure with an X. what walkie talkie to buy
ATEX Walkie Talkies for Explosive Atmospheres ATEX is a type of certification that ensures that the device that shows it is prepared to work in Explosive Atmospheres without catching fire.That is, those in which there is a mixture of flammable or dangerous vapors or mists. These types of walkies are essential for construction work, mines, for firefighters and do not have more than one watt of power. There are different types.
Zone 0. When the walkie must operate in an explosive atmosphere for a long time, such as in areas with flammable fuel (gasoline). Zone 1. When the walkie must operate in areas where there is no constant exposure to flammable substances, such as gas stations. Short periods Solvent storage areas. Group I equipment (for mines and quarries). M1. High degree of protection for mining equipment. M2 Total reliability to work in mines.
Group II equipment (no mining, more valid for quarries). CAT 1. Valid for work in areas where the walkie talkie can ever be exposed to explosive substances (such as gas stations). CAT 2. Security for extraordinary conditions (fire).
CAT 3. Safety for normal conditions. Tetra Digital Walkies Within the range of Motorola Digital Walkies offered by Tecnitrán, the TETRA (Trunked Radio system) models stand out.
It is currently the most advanced telecommunications system in the two-way radio market. It is a protocol for digital radios that ensures maximum quality in transmissions, as well as greater privacy and security in them, with the most advanced encryption and protection systems. The system was designed to cover the special needs of security and emergency bodies, such as police, fire, military or ambulance. Although it is also used in infrastructure such as airports or train stations. Among its features highlights its ability to access Internet or telephone networks (both fixed and mobile). That is, these walkies can be transformed into smartphones at the user's request.
Other advantages of this system are: It can be used in all EU countries. Greater efficiency and speed in data transmission. They can communicate with each other, without the need for a network, but the devices must be at a small distance. A single walkie can function as a repeater to amplify the signal.
Disadvantages: Its price (they are much more expensive), without the cost of setting up the network infrastructure, which makes it even more expensive.
Accessories of a Walkie Talkie: Chargers, microphones and protectors
In case you need to buy an accessory for a Walkie Talkie, try to always be the same brand.
Chargers and batteries. It is recommended to have a spare battery for your walkie, especially in those cases in which the equipment will not be charged for a long period of time. There are also single and multiple chargers (when you need to charge several computers at once).
Auditive protectors. Protectors for works and environments with high noise levels, such as airports. In many cases they are mandatory by law.
PPT micro speakers. It is usually placed next to the shoulder or the flap to communicate quickly without pulling out the walkie and bringing it to the mouth. They are placed in the ear and are usually sold with PTT. Perfect for communicating discreetly, such as in discos and for security employees.
