Police walkie talkies are P25 (Project 25). These radios have standards that are developed to provide digital voice and data communication systems designed for public safety officials. Police radios are also equipped with GPS, Bluetooth, LTE and WIFI capabilities.

How far can 900 MHz travel?

The lower frequency radio waves of 900 MHz radios provide greater penetration through walls, trees and other obstacles, making it optimal for most non-line-of-sight applications. A typical AW900xTR Radio using high powered AW-15 15dbi antenna can go distances of up to 1500 feet with buildings and/or trees in the way.

How far will a 100 watt FM transmitter reach?

If an ERP of 100 Watt is used, it is very likely that 20 kilometers of range will be reached because a 100 Watt ERP is able to propagate a strong signal as far as 20 kilometers. If an ERP of 1000 Watt is used, it is very probable that the signal will reach 20 kilometers, and it will also penetrate eventual obstacles.

How far will a 4 watt CB transmit?

Transmitter power is limited to 4 watts in the US and the EU. CB radios have a range of about 3 miles (4.8 km) to 20 miles (32 km) depending on terrain, for line of sight communication; however, various radio propagation conditions may intermittently allow communication over much greater distances.

How far can you transmit FM legally?

Unlicensed operation on the AM and FM radio broadcast bands is permitted for some extremely low powered devices covered under Part 15 of the FCC’s rules. On FM frequencies, these devices are limited to an effective service range of approximately 200 feet (61 meters).

How far will 25 watts transmit?

For example, a 25 watt marine radio will roughly have a maximum range of 60 nautical miles (111 km) between antennas mounted on tall ships, but that same radio will only have a range of 5 nautical miles (9 km) between antennas mounted on small boats at sea level.

Urban Environment – Around 1/2 – 1 mile from handheld to handheld, up to 2 miles mobile to handheld, and up to 5 miles or more, base to mobile, with base antenna at 50′.

What radios do the military use?

The AN/PRC-117F Multiband/Multimission Radio, currently in use by all the U.S. military services, is a 30-to-512 MHz-band radio that incorporates several different software-defined waveforms, such as SINCGARS, HaveQuick, and old Type 1 encryption modes.

Can Walkie Talkies be traced?

2 way radios are difficult to trace. Two-way radios, also known as walkie-talkies, remain popular even after the advent of cell phones. Police and security forces, the armed forces, event managers, hunters and many others use them. Two-way radios are extremely difficult to trace.

What is the longest range ham radio?

The absolute maximum distance that you can talk over with a ham radio is around 4000 miles (6400 km). This would only be possible during something like an emergency if both antennas were high enough, such as up on top of mountain peaks or skyscrapers.

Which is better UHF or VHF walkie talkie? UHF is the better all around signal and is by far the most popular, so if you are in doubt, choose UHF. UHF signals don’t travel quite as far outdoors as VHF signals, but they do a better job of penetrating wood, steel, and concrete, giving you better range and performance in urban environments and around buildings.

What radios do Navy SEALs use? The AN/PRC-126 radio is used primarily 2-way radio telephone communication among special force team members in the field. AN/PRC-126 Radio is currently used by US Army, USMC, US Navy SEALs, USAF CCT and other special forces.

The 5 watt radio can reach up to 12 miles or more. Some handheld radios have 6 watts which can reach up to 20 miles in the right conditions.

What affects walkie talkie range?

The usable range of a walkie talkie is limited by a large host of factors, and most of these factors are very hard to quantify. Factors like the weather, the geometry of the landscape around you, the type of obstructions in the landscape, noise from other radio signals, and your elevation all play a factor.

Do walkie talkies need line of sight?

They can be blocked by obstructions such as walls. There is an invisible straight line of sight between the antennas and radios which can be bounced back and reflected. This is a common myth that two signals from different sources on the same channel collide somewhere in mid-air. Well, it is not like that.
