Although mobile phone communication is already very convenient, walkie-talkies are still needed in some special scenarios, such as fleet travel, construction site work, etc. Traditional walkie-talkies transmit signals through radio waves, but because the handheld walkie-talkies transmit power is small, if the distance is too far, the sound will not be received. As the 4G network gradually becomes popular all over the country, 4G public walkie-talkies came into being, such as this Jifeng public walkie-talkie M303.
looks roughly the same as an ordinary walkie-talkie. The pure black color scheme is both professional and dirt-resistant. The edges of the fuselage are supplemented with excessive rounded corners to enhance the feeling of holding, and there will be no obvious feeling of hand grip. The whole machine uses safe flame retardant material , which is strong and resistant to falling, supports IP54-level waterproof and dustproof, which can effectively resist the erosion of rainwater and dust in daily use, expand the use scenarios of the walkie-talkie, and extend the service life.
is equipped with a 1.77-inch color display screen on the front of the body, with four independent buttons underneath, which is convenient and intuitive to interact. The intercom button on the side is made of PC+ABS material, with a concave and convex surface, which makes it comfortable to touch and can withstand 80,000 pressing operations. The back is designed with an integrated back clip, which is convenient for daily carrying.
This public walkie-talkie relies on 4G network communication , and only needs to insert a SIM card. Compared with the traditional radio intercom, it can break through the distance limitation and communicate with each other in all places where 4G networks are covered. At present, domestic 4G base stations have penetrated into rural areas, and there are basically few blind spots to cover, which can achieve 5,000 kilometers of intercom nationwide. Purchasing walkie-talkies also comes with free one year of call traffic, and there is no platform fee.
Compared with the single chain of mobile phone communication, the walkie-talkie can realize one-to-many communication. On the Jifeng Public Intercom M303, group building and teaming operations can be independently completed, and various methods such as invitation code teaming and face-to-face teaming are supported. All of them are completed on the walkie-talkie, without tedious backend operations, reducing the cost of use and improving communication efficiency.
pulls the person who needs intercom into the group, and can compare intercom within the target range, and can call a certain member in the group, some members or all members. For example, when used on a construction site, commanders can not only talk to the captains of multiple squads, but also talk to all members of one of the squads alone.
Although WeChat group voice messages can also achieve one-to-many communication, their efficiency is far less than that of walkie-talkies. It takes 20 seconds to enter a 20-second voice message on WeChat, and it takes another 20 seconds to listen to the message after the other party receives the message. The 4G public intercom can realize real-time sound transmission. Just like making a phone call, the other party can hear the sound in real time, shortening the time for receiving information.
It is worth mentioning that the Jifeng Public Intercom M303 is equipped with a 2W high-power speaker with a unit diameter of 360 mm. It has a loud sound and clear voice. Even in a noisy outdoor environment, you can clearly hear the voice of your teammates, improving the voice quality experience of the call. After the call of
, you can also listen to the previous conversation recording on the intercom, similar to WeChat voice messages, which is also a function that traditional radio intercom does not have. For example, the team leader can listen to the key points of the leader's speech in order to arrange follow-up work.
Considering that it is not convenient to hold the intercom at any time in some special scenarios, the M303 is also equipped with a dual-mode Bluetooth chip, which can be used with Bluetooth headset , so that you will not miss important intercom information while freeing your hands. Of course, it also reserves a 3.5mm headphone jack, which can be used with wired headphones when Bluetooth signals are easily disturbed, providing dual insurance . In terms of battery life, it has a built-in lithium battery with a capacity of 3000mAh, and has low power consumption optimization at the software and hardware levels. It can meet 100 hours of normal standby, and it can be used for about 60 hours in continuous use. The charging adopts the mainstream Type C interface, which can be used with a mobile phone data cable to charge, and supports various charging methods such as car charging and mobile power supply, and can recover blood anytime and anywhere.
Overall, 4G public network intercom has many advantages that traditional radio intercoms do not have. They break through the distance restrictions and can communicate normally across the country. They are more efficient than telephone and WeChat communication, and are of great significance to use scenarios such as collaborative office and fleet travel. As for the Jifeng Public Intercom M303, the body uses solid materials, strong anti-fall, dust and waterproofness; it is equipped with high-power speakers, loud sound and clear calls; the intercom directly completes group building, grouping and other functions, which facilitates targeted intercom; it supports the use of wired and Bluetooth headphones, freeing hands; the 3000mAh battery meets 60 hours of ultra-long battery life.
