The best walkie talkies to communicate without the need for coverage

The massive use of mobile phones has narrowed their market, but they continue to be sold because, in specific situations and places, they continue to be very useful. For example, they do not depend on their coverage on being in the radius of any antenna. And it is not their only comparative advantage although, of course, they also have drawbacks.
The acquisition of these terminals is linked to particular objectives and extreme conditions. They are indispensable in emergencies or cases of natural disasters. But they are also so in normal situations and much more common places such as seaports, construction sites or large conventions.
Also, they are efficient in activities such as hiking, cycling, mountain excursions or outdoor activities with detailed telephone coverage.
In this selection, we opted for a free-use Cacagoo model for sports and home environments, which for an economical price is very practical for many occasions.

Operating mode

Walkie talkies are transceivers made up of a transmitter and a receiver. As long as a receiver is within its range of action, it can send signals without depending on any external component.

One of the differences and drawbacks about telephones is that walkies can only transmit on one channel. That is, one speaks, and another or others listen. Another or others because the signal can be received by several.

This feature largely explains how they work. Thus, they have the Push To Talk button (known by its initials PTT) that is pressed to transmit and that when it is released, it reproduces the sound it is receiving.

Hence its well-known code composed of “change” when what you want to communicate is finished and “change and short” to end the dialogue.

This is, let’s say, the classic operation that has changed with technological advances. Some models already have an indicator that indicates that the PTT has been released without the need for the verbal code.

How many types are there?

The typology of these devices is not fixed since it can attend to different factors. Among other variants, they can be classified by their technology or their use. Thus, depending on their technical characteristics, precisely according to the type of signals they use to transmit information, they can be divided into:

Analogues.- In apparent decline compared to the higher quality of digital. It is usually a signal more faithful to reality and, however, what apparently would be an advantage is not so much in this case, since it captures any sound in the environment. At the same time, the digital one focuses more on the voice and arrives more clearly.

The voice in analogues is distorted more quickly as one moves away from the coverage radius.

Digital.- They are the vast majority today for their many significant advantages over analogue. In this way, this type of technology allows a higher sound quality, more comprehensive coverage and longer battery life. There are also some ‘analogue-digital’ hybrid models on the market.

With Tetra technology.- This type of technology (Terrestrial Trunked Radio) is the most advanced and safe on the market for these devices. Maximum security in transmissions thanks to its encryption systems and protection mechanisms. It is the type of walkie talkie used for emergency or public safety purposes.

As noted, the use to be made also implies differences:

Free to use.- They do not require a license or fee payment. They are the simplest ones intended for uses related to outdoor leisure activities. Other more sophisticated models that are used in shops, discos or conference rooms also fall into this section. When used free of charge, they are limited in frequency (446 megahertz) and power (0.5 W).

Professional use.- You must pay a fee for its use. In exchange, there is an exclusive frequency, and, therefore, communications will be private. These are much more complex and resistant terminals. They also have higher frequency and power ranges than those for free use. Within them, subdivisions are depending on the scope of use: marine band, airband or citizens band for civilian personnel.

Advantages and disadvantages to the mobile

Although by several users there is no possible comparison, walkies have more than one advantage over mobile phones.

Advantages of the walkie:

• Economic factor: In the case of free-use ones, the vast majority have no more expensive than the purchase of terminals, which are also much cheaper than mobile phones.

• Agility of use: Press the PTT button for immediate communication. Neither numbers nor contact book are necessary.

• Full coverage: You do not need antennas or coverage areas. It is reliable even if there is no electricity or telephone network.

• Robustness: Its resistance is enormous. No fear of it falling.

• Design: Very ergonomic to be able to take them with total comfort since they are designed for adverse situations (for example, take it with gloves for protection against an incident).

mobile advantages:

• Fluency: Communication is more fluid since it allows a simultaneity that the walkie talkie does not have.

• Sound quality: Although with the digital versions, it has improved a lot in the walkie, it does not reach in general that of the mobile.

• Versatility: It reaches the extreme that nowadays, through applications, the communication mode of walkie talkies can be transferred to a mobile phone. For example, with the ‘Zello’ app.

What to look for

Frequency mode .- There are two: UHF and VHF. Both types are not compatible with each other. Therefore, it is essential to take it into account, mainly if the purchased equipment is going to be used with other devices.

The fundamental difference between the two is the wave distance. It is higher in VHF and therefore ideal for large areas without obstacles.

The UHF frequency, on the other hand, is made up of shorter waves, which in practice means that it has a shorter range but more easily overcomes obstacles that may exist in communication. Therefore, it is more restricted to the urban environment.

Battery.- In general, in this aspect, they surpass mobile phones. And they have batteries of two materials fundamentally. On the one hand, the nickel ones that can reach up to 12 hours without charging. On the other, those of lithium that go up until 8:00 p.m. and are more expensive.

Protection level.- This is a parameter reserved for professional walkies. The degree of protection IP (Ingress Protection) indicates the level of tolerance to water and dust and consists of two numbers: The first sets the tolerance to dust from 3 to 6. The higher, the more resistant. The second establishes the resistance to liquids. Likewise, the higher the number, the more reliable.

Scan function.- It is in charge of automatically searching for the least saturated channels to find the best communication.

Emergency call.- It is a device that is programmed so that in case of emergency it can autonomously issue a call.

Model of one of the most recognized brands. The medium-high range at a high price. Even too much according to some users.
However, it works well in situations that are difficult for wave expansion, such as large-format concerts. And another of the significant advantages of this model is that it can be synchronized with other brands and share a channel.
It also copes without problems with communications in adverse weather conditions. For example, they are efficient in the discipline of skiing.
They are quite solid walkies due to the material, although by size they may seem a bit long compared to other more ergonomic models.
