work in security using walkie talkie need to extend distance range.

How to Extend Walkie Talkie’s Distance Range ?

Many customers mentioned the distance range of walkie talkie can not accept such long distance as advertisement. Then, how to extend walkie talkie’s distance range ?
Radio communication is ultrashort wave communication, distance range influenced by buildings, hills, trees, electromagnetic fields, such as blocking and interference, affect the actual distance and quality.Pls check more info. about How to Extend Walkie Talkie’s Distance Range .

Walkie talkie Equipment Factor:

1.Power:

The bigger of the output power,the greater the emission signal coverage,the farther the distance range .
A 0.5-watt system might require users to be within 100 yards (91.4 m) of each other, while a 5-watt system might extend that distance up to 10 miles (16 km). The maximum communication range is generally determined under perfect conditions, meaning that there are no forms of obstruction between the two walkie talkies. When buildings are in the way, the range of indoor communications is typically reduced dramatically because of the various elements of building construction.

2.Receiving Sensitivity:

The higher walkie talkie receiving sensitivity, the further the distance range .

3.Antenna:

the higher high gain ,the greater of the power, the further of the distance range.

4.Frequency:

UHF (ultra high frequency) and VHF (Very High Frequency),See details. UHF or VHF : Which Is Right For You?

Environmental factor :

Environmental factors mainly include path, the density of trees, electromagnetic interference environment, buildings, weather and terrain difference, etc.

Other factors:

1.Low battery :

When low battery, call quality will become worse ,even worse,there will be noise, influence the normal calls.

2.The antenna matching:

Frequency and inconsistent machine frequency antenna, antenna impedance mismatch, will seriously affect the distance.

3.Horn (Speaker) configuration:

The higher price walkie talkie,the better speaker configuration , so the walkie talkie will keep good sounds quality.

4.Base station:

When u have a base station and repeater nearly, wlakie talkie’s distance range will be amazing !

5.Season :

The summer better than winter.

Any idea about how to extend walkie talkie’s distance range ? Welcome to share with retevis !
