DATA901 Frequency Hopping Wireless Data modem

  • undefined

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.

Industrial Communication


Transparent Data Channel, Low Delay Link

Encryption support

Air wireless link rate up to 19.2 kbps

Four-stage filter provides superior noise suppression and anti-interference capability.

There are many networking modes: point-to-point, point-to-multipoint, relay storage and forwarding, and TDMA.

Maximum transmission power 1W (adjustable), larger transmission power 5W, 10W customizable;

Low Power Sleep Mode

32 bit CRC, forward error correction mode and retransmit can be selected

Superior anti-interference ability, Multi-stations can communicate in the same frequency band at the same time, without interference with each other.

Roaming support: When one path is interrupted, another path can be automatically connected.

Supporting relay, a single device can form a relay, saving a radio station.

Relay stations can also be spare stations to save equipment; there is no limit on the number of relay stations in the network
