KS Series | 天则通信

PRODUCT PROFILE

The KS dual-frequency series is a self-developed TDD bidirectional image and data integrated backpack device. There are a total of two models. KS614 supports 600MHz&1.4G, and KS914 supports 900MHz&1.4G. The product features real-time interference detection, adaptive frequency selection, adaptive code stream, automatic retransmission and automatic power control functions, which significantly enhance its anti-multipath and anti-interference capabilities. It is characterized by high reliability, good stability and low latency. This product is suitable for scenarios such as fire protection, inspection, and monitoring. Under good environmental conditions with air-to-ground visibility, it can transmit over a distance of more than 30 kilometers.

PRODUCT FEATURE

Support dual-track technology with different frequencies: Support independent frequency hopping transmission at each uplink and downlink frequency point
Support long-distance transmission: With a 4M code flow, the transmission distance can reach over 30km depending on the situation
Support for high bandwidth transmission: Maximum support 23.9Mbps@20MHz
Support for automatic relay transmission: Support relay mode
Support automatic frequency selection: Automatically detect interference signals and select the optimal frequency in real time
Support for automatic retransmission: Automatically retransmit sudden error data to enhance data reliability.
Support adaptive bitstream: Automatically adjust the channel modulation mode in real time according to the signal quality
Support for automatic power control: Automatically adjust the transmission power at short range to reduce power consumption
Support for automatic antenna selection: Select the optimal antenna for transmission in real time based on the occlusion situation
Support dynamic allocation of uplink and downlink: The bandwidth proportion of the master and slave uplink and downlink can be automatically allocated according to the actual data volume
Support frequency synchronization function: Frequency synchronization can be configured through software and through hardware keys
Support for external remote controls: Supports the use of external remote controls in conjunction
