Walkie-talkie as a key communication equipment, its stability and reliability is highly dependent on the core components – crystal oscillator, for the walkie-talkie to provide accurate clock signals, determines the RF signal generation, synchronization of digital protocols, low-power management, anti-jamming and other core functions.
First, the irreplaceable core advantages of walkie-talkie
1. Instant communication: no dialing, no delay group call function, in emergency command, site collaboration and other scenarios far more efficient than cell phones.
2. No network dependence: analog/digital walkie-talkie communicates through its own frequency band, which is still available in disasters (earthquakes, floods), remote areas (mines, sea) or when the network is paralyzed.
o Case: During the Zhengzhou rainstorm in 2021, the public network was down and rescue teams relied on walkie-talkies for dispatch.
3. Durability and Cost: Professional walkie-talkies are drop-proof, waterproof, and have a one-week battery life (e.g., Motorola GP3688), making them suitable for harsh environments, and the long-term cost of using them is lower than cell phone traffic charges.
In the future quite a long time to see, walkie-talkies will not completely disappear, will still dominate in the professional field (engineering, security, emergency), but the form will be smarter, multi-mode.
Walkie-talkie in the future form, may be more specialized segmentation, like explosion-proof, military-grade equipment still can not be replaced, the construction industry may turn to AR smart helmets (such as RealWear) integration of intercom, drawing view and AI guidance
