On May 16, China Telecom and Lao Telecommunications Company (ETL) jointly held a product launch event in Vientiane for the Tiantong Satellite-to-Phone Direct Connection Service, marking the official international debut of China's independently developed Tiantong satellite system and the commencement of its strategic expansion into the Southeast Asian market.

Lezhong New-Generation Self-Organizing Network System is designed for complex scenarios such as underground tunnels and mining passages. It reconstructs underground communication lifelines with self-organizing network technology, enhancing safety and emergency response efficiency.

Lezhong offers a complete portfolio of self-organizing network product solutions tailored to diverse application scenarios.

The new generation of LeSat self-organizing network devices LeSat X8 and LeSat X9 are completely different. They have the characteristics of "no center, self-organization, high bandwidth, and no peripherals", and can be networked anytime and anywhere, and achieve voice and video communication.

As a self-developed communication tool in China, the Tiantong satellite phone plays an important role in remote areas without signal coverage. But sometimes, we may encounter situations where we are unable to make satellite calls to Tiantong. This article will provide you with a detailed analysis of possible reasons and offer corresponding solutions.

LeSat satellite phone fixed mobile dual-use landline terminal has played an important role in emergency communication, and its "fixed+mobile" characteristics can also play a communication role in many other scenarios.

The China International Fair for Investment and Trade, hosted by the Ministry of Commerce of China, was held as scheduled in Xiamen, Fujian. At the Industrial Innovation and Development Hall, LeSat series Tiantong satellite phones were unveiled at the China Telecom booth.

When disasters strike and communication is damaged, Tiantong satellite phones are widely used in emergency rescue operations to ensure communication at all times. As the communication terminal of the Tiantong-1 satellite system, the Tiantong satellite phone shoulders the responsibility of emergency communication. It demonstrates significant advantages in ensuring communication stability and reliability during disasters.

The LeSat F4 landline terminal model is the LeSat G3 (F4) multi-mode satellite communication fixed mobile dual-use terminal. It is an indoor Tiantong satellite phone that can be used by combining the LeSat F4 with the LeSat G3 base and using it in conjunction with an outdoor flat panel antenna.
