1. Overview of Lora Wireless Synchronisation

Lora, as a long-range communication technology within the Low-Power Wide-Area Network (LPWAN) spectrum, has garnered increasing attention in recent years. As one of the LPWAN communication technologies, Lora represents an ultra-long-range wireless transmission solution based on spread-spectrum technology, adopted and promoted by the American company Semtech. Operating on linear frequency-modulated spread spectrum modulation, LoRa retains the low-power characteristics of FSK modulation while significantly extending communication range.

The standard time information generated by LoRa wireless synchronisation clocks has become a fundamental support platform across sectors including telecommunications, power distribution, broadcasting, scientific research, security surveillance, and industrial control.

The LoRa wireless synchronisation clock is a foundational timing application product developed using the latest high-precision LoRa timing module. It can output time information formats compliant with user-specified protocols to deliver synchronisation services. Primarily utilising its built-in LoRa wireless timing module, the clock receives standard time from base stations, NTP networks, Wi-Fi, GPS satellites, and BeiDou satellites. This enables the acquisition of highly stable frequency information alongside locally recovered, smoother time reference signals.

2. Application Scope of LoRa Wireless Synchronisation Clocks

(1) Various time synchronisation systems acquiring standard time via satellite synchronisation;

(2) Computer networks, computer application systems, and process control management systems;

(3) Time unification systems and various time display screens for power plants (stations) and grid dispatch centres;

(4) E-commerce systems, B2B online systems, and database preservation and maintenance systems;

(5) Fields including factory power, finance, mobile communications, petroleum, electricity, transportation, industry, and national defence;

(6) Urban areas with dense construction and suburban regions.

3. Advantages of Lora Wireless Time Synchronisation

Lora technology inherently possesses exceptionally high reception sensitivity (RSSI) and superior signal-to-noise ratio (SNR). Furthermore, employing frequency hopping technology with frequency shift keying via pseudo-random code sequences enables continuous carrier frequency hopping to spread the spectrum, thereby preventing fixed-frequency interference. Its most significant characteristics are extended transmission range and low operational power consumption.

Wireless time synchronisation systems employing LoRa require our TQ7710 device, which acquires time via GPS. Advantages of the LoRa wireless synchronisation system include:

1. Autonomous control; time is directly obtained from GPS, rendering it impervious to external interference;

Within a designated area, no cabling is required, substantially simplifying installation.
