DATA901 Frequency Hopping Wireless Data modem is an all-digital data transmission modem, produced by Beijing sagetwon technology Co.,Ltd . Its core technology is based on frequency hopping technology (FHSS), which is widely used in military communications. It has excellent anti-interference and confidentiality ability. It can provide reliable data communication in harsh electromagnetic environment, and has the recognized superiority in the industry.

DATA901 Frequency Hopping Wireless Data modem is small in size and light in weight. It is especially suitable for areas with strict requirements for both volume and weight, such as unmanned aerial vehicle, single network radio , handhold equipment, embedded design, wearable equipment, etc. The operating frequency range is 902-928 MHz. 1W transmission power, excellent anti-harsh environment and electromagnetic compatibility index, but weighs only 160 g. It can be applied in almost all environments.

DATA901 Frequency Hopping Wireless Data modem provides robust data communication with high speed and low delay. It has excellent anti-blocking performance, robust digital links, powerful networking capability, full-signal data ports and supports remote online diagnosis.
