What is the farthest distance of wireless walkie talkie?
Commonly used wireless walkie-talkies generally use 130-170MHz; 403-470MHz two bands, these two bands are also national laws allow individuals or units to use the band range. Under normal circumstances, the two wave frequencies are transmitted linearly, maritime communications is the earth's radio intercom relatively ideal communication environment, there will be no obstruction and rarely interfere with, but in fact, the walkie-talkie at sea can only It's about 10-20 knots, because the earth is round, too far from the middle of the sea (so the antenna is taller and the call distance is farther away).
When used in cities in general, obstructions are the most influential factors on the signal propagation distance. Professional walkie talkie with power up to 5 watts in the city of the actual call distance is generally only in the range of 2 to 5 km. In the high ground, more buildings or more sealed room, the call will be short distances. However, when the system base station support, walkie-talkie calls up to tens of kilometers or even tens of kilometers, (if the two walkie-talkies are high, you can reach more than ten kilometers).
