How to Choose and Use the Right Walkie Talkie?Max Telecom
There are places where none of the cell-phone networks work at all. Further, there are numerous zones, where cell-phone signals betray. That is not the case with Walkie Talkies.
Simply because airwaves do not betray!
A Walkie talkie or two-way radio depends upon radio signals transmitted through radio-waves. It finds wide usage in both commercial and non-commercial scenarios.
Usage decides the Right Model and Manufacturer for You
Walkie Talkies find application on construction sites, large industrial plants and event management etc. They have become indispensable for military and police teams. Specialized devices are also making their way into marine and aircraft communications. They have emerged as important equipment for dynamic group co-ordination.
Walkie-talkies also work as amateur radio. This pertains to the non-commercial use of the devices. Kenwood Walkie Talkie sets are considered reliable for radio-training, educational purposes, experimentation and radio sports. They are also handy when it comes to everyday scenarios that might require emergency communication.
2-way radio devices are also useful for recreational purposes. For a camping trip, a Motorola Walkie Talkie with specialized emergency readiness feature could be a great choice.
It is the utility of the instrument that decides the right manufacturer and model for you. The scenario in which the instrument would be used depends upon the utility of the device.
The following variables help you zero-in on the right Walkie-talkie device.
- Radio Frequencies
Walkie Talkie devices are available in basically two frequency bands. There are Very-high Frequency (VHF) devices and Ultra-high Frequency (UHF) devices available in the market.
VHF devices usually operate at frequencies in the range of 130-174 MHz. They are better suited to long-range communications. UHF walky talky has a frequency range of 400-512 MHz. They are suited to short-range transmissions but work well in densely populated areas. They offer greater number of channels. The chances of being interfered by distant radio channels are also minimal.
VHF devices are ideal for environments that have little obstructions. UHF devices are better for environments where radio-waves have to penetrate through obstacles such as concrete or steel walls.
- Range of Operation
2-way radio devices seldom operate at the ranges that their packaging or manufacturer commits. The 15, 25 or 50 km range cited is for an absolutely obstacle-free environment. That is hardly the case in reality! Obstacle free environments are exception than the norm.
Better quality 2-way radio devices emit stronger radio-waves. Stronger waves mean more obstacles can be penetrated. Usual obstacles are buildings, cars, large metallic structures and natural environments like forests. They may also include other 2-way radio users in the surroundings.
The effective operating range is much less than what the manufacturer claims. Thus, a 25 km range device might only be able to work for 5 km or even lesser ranges.
Digital walkie-talkie sets are better equipped to deal with obstructions. Some digital devices shift the frequency more than a dozen times a second. This makes interference in your channel by others in the surrounding difficult. You can consider buying or renting 2-way radios that work with both analog and digital frequencies.
- Battery Life
Usually, 1 watt of battery power means 1.6 km of coverage. Therefore, more the wattage of the battery, more the range your device would cover. VHF devices consume lesser battery as compared to UHF devices in general. However, the coverage range per watt might come down due to obstructions. Including weather fluctuations!
2-way Radio sets are available with mainly two types of batteries. Lithium-ion batteries are in vogue for non-commercial consumer users. They are equally attractive for business users because of the high-capacity that they offer.
Nickel-Metal Hydride or NiMH batteries are more durable and better suited to rough usage. They offer excellent resistance to impact. They charge quicker than their Lithium counterparts. However, due to their thermo-sensitive nature, this advantage might get cancelled over time.
More than Utility and Technical Aspects that you need to Consider
Walkie Talkie sets can be expensive. Hence, it is wise to choose walkie talkie on rent especially when the usage is of occasional nature. Finally, make sure that 2-way Radio’s that you have chosen do not require licenses and permission from authorities. If they do, you would need to do some paperwork.
