- CX660X Module Usage
The CX660X is a point-to-multipoint broadband data transmission module. Based on the LTE wireless communication standard, it utilizes key technologies such as OFDM (تعدد الإرسال بتقسيم التردد المتعامد) and MIMO (Multi-Input & Multi-Output). The module supports multiple bandwidth allocations (1.4ميغاهيرتز, 3ميغاهيرتز, 5ميغاهيرتز, 10ميغاهيرتز, and 20MHz) and features a flat system architecture design, effectively reducing system latency and improving transmission capability. It offers long-range transmission, high data throughput, and strong anti-interference performance. Equipped with an SOC chip, the CX660X achieves higher integration, significantly reduces system power consumption, and minimizes module size, making it ideal for customer applications such as UAVs and video surveillance systems.
