Normal walkie-talkies just transmit directly from one radio to another. The likely range that can be expected from walkie-talkies can vary from a few hundred metres to a couple of miles or more. A radio that might have a range of 2 or 3 miles in open, fairly flat countryside may only work over m in city streets. All brands of walkie-talkie have basically the same power output, and therefore approximately the same range. You won't find that one brand of radio has a range twice as good than another, because they are all subject to the same basic laws of physics.
We now sell and hire a totally new type of "radio" that contains a SIM card like a mobile phoneand that transmits its signal via the mobile phone data networks. These radios get around the point-to-point range limitation of conventional walkie-talkies, and can transmit over any distance at all, provided that both ends are positioned somewhere that has a mobile phone signal.
They are best suited for events in towns and cities where there is good mobile network coverage, and where "normal" walkie-talkies range is badly affected by lots of big buildings between one radio and another. But if you plan to use your radios only in open countryside or at sea - maritime radio is VHF then VHF is better for absolute range.
Not sure where to start? No matter what kind of event you are organising, we have walkie-talkie radios to suit your needs for short and long term hire.
For many events attended by the general public, a megaphone is a useful tool to address and control the crowds. Get your message across! Walkie-talkie radios have many uses around schools, colleges and universities. We have sold and hired radio equipment to thousands of schools and colleges from small primary schools up to large secondary schools, colleges and universities. However, VHF signals really do not work well when there are obstructions like buildings around.
For most users who want their radios to be "good all-rounders", UHF is the best choice.Dr wu dds

In real-world conditions with trees, hills and obstacles expect no more than 3 miles. The range that manufacturers post tends to be the highest possible range in the most optimistic of conditions -- and this is being charitable. Depending on where you are in the type of environment radio signals between the walkie talkies behaves in different ways.
If it has a straight line of uninterrupted travel then it can carry much further. The more objects and obstacles you lay between one radio and another the more choppy the signal becomes until there is a point where not enough of the information within the signal can reach the receiver and communication become impossible to decipher. Here are some different scenarios and the expected range you would get with the average recreational two-way radio setup.
Yes, generally bad weather like storms, fog or cloud will impact the power of the signal and reduce your range. There are few ways to improve your walkie talkies range without going out and buying a brand new walkie talkie.
Surprisingly the curvature of the Earth even on short distances does have a measurable effect on your range. The curvature is approximately 8 inches per mile or 1 foot every 1. The higher your can get yourself the more your range will be with all things being equal. A higher range allows to overcome obstacles like trees and buildings and project your signal further across the landscape.
Although it might seem like a minor issue, the way you hold your walkie talkie has a surprising affect. The waves are transmitted omni-directional around you.
If you have your radio held on its side or at angle then the distance the signal can project will be noticeable smaller. The Retevis two way radio antenna view on Amazon comes in a pack of 5 and does a good job of extending your radio -- check the compatibility first. If the extender is compatible, you can unscrew your current antenna and screw in the extender for better range and sharper signal.
Using the rechargeable battery that comes with the radio will improve your range and should be used primarily. There are 22 channels in the U.What frequencies do you need to program into your emergency radio
S that can be used by recreationally under the Family Radio Service frequency which is usually more than enough for most situations. Sometimes when the airwaves are crowded these channels are not enough and you can often pickup interference or other peoples radio chatter throughout the day. Not only can this drain your battery but it can interfere with communication from others in your party. The best way to overcome this is to use privacy codes.
Most newer walkie talkies have this feature and it is a subset of channels within the channels that allows you to communicate without interference. More on privacy codes here:. I reviewed this and my other top picks in detail over on my piece: Best Walkie Talkies reviewed. Walkie talkies and two-way radios are essentially the same thing. If you want a more thorough breakdown check out the comparisons here.

There are only eight pre-programmed channels, with the following frequencies: 1 Specific channels are used for particular purposes, including for emergencies, ship-to-shore communications etc.Sanwa multimeter cd800a
FRS has 14 channels, numbered below. These radios are often bought by British holidaymakers in the US or Canada or the Caribbean, or on cruise ships, and then brought back and used in the UK, with the buyers not knowing that they are breaking the law.

We have sold and hired radio equipment to thousands of schools and colleges from small primary schools up to large secondary schools, colleges and universities. Radio Frequency Information Radios transmit and receive messages on any of millions of possible frequencies. Radio frequencies are expressed in units of Hertz cycles per second.
The units used are usually KHz kilohertz and MHz megahertz. All rights reserved. Website by: Frontmedia.Most walkie talkie users understand the basic concept of how handheld 2-way radios work: signals are transmitted and received through dedicated channels or radios frequencies.
But, it gets a bit confusing when you try to unravel what frequency walkie talkies use while people are exchanging messages. For novices, and many veterans who have no time for the technical side of things, that confusion is understandable.
After all, in getting to know the specifications of the best walkie talkie to buy for a road trip, camping, skiing or some special outing with friends and families, you'd come across some recurring themes like UHF, VHF, FRS, GMRS, and so on. These codes make it possible to have thousands of channel or frequency combinations thereby giving you almost unlimited options of frequencies to choose from. Typical handheld 2-way radios are designed to transmit and receive radio signals over a wide bandwidth of radio frequencies.
For private citizens, these channels or frequencies have a limited number available for use.Lucia paciaroni
Most of the frequencies are used by the police, military, government, licensed private entities, and other security agencies. The frequencies opened to individuals vary from country to country. This information is important if you want to use the walkie talkie in a different country. You would need to find out from the authorities which frequencies are open to private citizens to avoid running foul of the law. In terms of bandwidth, VHF is longer than UHF and is ideal for long-range communication out in the open where there are no obstructions.
For instance, a VHF walkie talkie would be best high up on the mountains and for ship cruises where there is no little or no obstruction. Because UHF has the capacity to perpetrate or go around obstacles such as walls, buildings, and steel, they are more suitable for use in urban areas and inside buildings. Generally, you need a UHF device if you want to use the radio both indoors and outdoors.

They are a bit more expensive than VHF devices. By international conventions, the allocation of walkie talkie frequencies varies from one country to the next. There are five main channels that are available in the US. These are:. However, private citizens can be allowed to use restricted channels, such as the GMRS frequencies, if they get permission from the FCC. It could be because they are not aware of the law or they simply don't care.
Weak enforcement of the law means lots of people get away with using GMRS permits without a license. The license gives you the right to communicate at up to 5 watts of power. The hybrid walkie talkies typically do not need a license to operate it. They are privacy codes that sometimes come with different manes depending on the manufacturer.Twinmotion import material
These codes make it possible for handheld 2-way radios to keep communication 'quiet' if the particular chosen code is not received when a message is broadcast.
Basically, privacy codes allow the device to ignore transmission from other parties even if they are on the same channel. To put it another way, the codes create sub-frequencies or channels giving you a private channel to communicate. Because of the number of privacy codes in walkie talkies, hundreds of extra channel combinations are possible making it more likely to get a frequency that is unoccupied.
But privacy codes don't really encrypt communication or give you exclusive access to some frequencies. That must be made clear. If coincidentally, somebody tunes into the same channel or frequency with the same privacy code, they would be able to listen to the conversation.Since the UHF band has different radio propagation characteristics, short-range use of FRS may be more predictable than the more powerful license-free radios operating in the HF CB band.
Initially proposed by RadioShack in for use by families, FRS has also seen significant adoption by business interests, as an unlicensed, low-cost alternative to the business band. Worldwide, a number of similar personal radio services exist; these share the characteristics of low power operation in the UHF or upper VHF band using FM, and simplified or no end-user licenses.
Exact frequency allocations differ, so equipment legal to operate in one country may cause unacceptable interference in another. None of these radios working with frequencies in the FRS frequency band are legal to operate anywhere in Europe.
The channels are spaced at Although these codes are sometimes called "privacy codes" or "private line codes" PL codesthey offer no protection from eavesdropping and are only intended to help reduce unwanted audio when sharing busy channels.

Tone codes also do nothing to prevent desired transmissions from being swamped by stronger signals having a different code. Radios are not certified for use in this service if they exceed limits on power output, have a detachable antenna, allow for unauthorized selection of transmitting frequencies outside of the 22 frequencies designated for FRS, or for other reasons.
FRS radios must use only permanently attached antennas,  ; there are also table-top FRS "base station" radios that have whip antennas. This limitation intentionally restricts the range of communications, allowing greatest use of the available channels by the community. The use of duplex radio repeaters and interconnects to the telephone network are prohibited under FRS rules. FRS manufacturers generally claim deceptively exaggerated range [ citation needed ].
The presence of large buildings, trees, etc. Under normal conditions, with line of sight blocked by a few buildings or trees, FRS has an actual range of about 0. Combination radios will be permitted to radiate up to 2 watts on 15 of the 22 channels as opposed to 0. Interference to licensed services may be investigated by the FCC. This will not include amateur and other radio equipment that are not certified under Part 95, such as many handheld radios that are marketed for amateur use but are also able to transmit on FRS and GMRS frequencies.
Since tourists often bring their FRS radios with them, and since trade between the U. Portable radios are heavily used in private communications, mainly by security staff in nightclubs and malls, but also in private parking, maintenance, and delivery services. Many personal radio services similar to the FRS exist around the world. Because radio spectrum allocation varies around the world, a personal radio service device may not be usable outside its original area of purchase.
FRS equipment may not be legally permitted in other countries because it uses frequencies allocated to services such as police or fire; however, many countries have equivalents to the FRS.

The Family Radio Service FRS is a private, two-way, short-distance voice and data communications service for facilitating family and group activities. The most common use for FRS channels is short-distance, two-way voice communications using small hand-held radios that are similar to walkie-talkies.
Walkie Talkie Radios & Range
FRS is licensed by rule. This means an individual license is not required to operate an FRS radio provided you comply with the rules. You may operate an FRS radio regardless of your age, and for personal or for business use if you are not a representative of a foreign government. There are 22 FRS channels. Each channel has a bandwidth of You can operate a FRS transmitter at any place where the FCC regulates radio communications, subject to certain limitations.
None of the FRS channels are assigned for the exclusive use of any user.
You must cooperate in the selection and use of the channels in order to make the most effective use of them and to reduce the possibility of interference. The usual range of an FRS device on channels is less than one-half mile, but longer range communications can be achieve on channels and depending on conditions. You may not interconnect FRS transmitters and radios with the telephone system.
