Nowadays,  many people pay attention to the healthy lifestyle, many travelers will choose to travel or climb the mountain to relax, there are unpredictable dangers and situations in the middle of the mountain, this time tourists will choose a communication equipment, through the two way radio and external communication or teammates, then how to choose the two way radio has become a lot of tourists trouble.

At present, the two way radios sold on the market generally have several types of business, family, sports and leisure, people can choose different power, different performance and different shapes of the two way radios according to demand.

In the case of occlusion, the two way radio should choose a product with a relatively low working band. Radio waves are actually a kind of light, only at a much lower frequency. When an electromagnetic wave encounters an obstacle, if its wave is smaller than the size of the obstacle in the long run, it will be reflected, absorbed and blocked. If the wavelength is close to the scale of the obstacle, it will be scattered, but some of it will propagate through diffraction. When the wavelength is larger than the obstacle scale, diffraction propagation is the main component, so it will not be blocked.

Specifically, managers of hotels and entertainment venues can choose business radios, which can enable managers to talk with related employees such as the foreman when answering customer calls; Equipment installation and construction enterprises can choose two way radios with noise-cancellinhg function (such as SenHaiX N301) to remote control field command; Tour guides of travel agencies can choose two way radios with large power and many channels to contact scenic spots, restaurants, drivers and so on in time. Two way radios used for hiking or field trips generally hope that the diffraction characteristics are better, so the working frequency band is lower.
