Product details
Model Number: SG-TDD20(02) Brand Name: Safe Guard Key Specifications/Special Features: Features: 1. Advancement: TDD-COFDM channel modulation technology, supportfast-moving, ultra-wide band, and fully transparent transmission.2. Security: private network, private communication transport protocol, sole synchronization codeand AES encryption and alsocustomer manually customize the secretkey3. Flexibility: transparent transmission of IP data channel supports multi-user access.4. Scalability: all-digital network is compatible with all IP data transmission equipment.5. Bit rate can up to 921600bps6. Support protocolPTP &PMD network technology7. Support non-line of sight (NLOS) high speed mobile transmission8. Standard RJ45 Ethernet and RS485/RS485/RS422 data interfaces9. Built-in with small LCD screen that shows the signal working status.
10. Available frequencies: 330--530MHz (choose 40MHz interval), or 2.4GHz (option).

Technical performance:

1. Multi-frequency network base stations, single base station same frequency network, the same frequency network with bidirectional communication, high spectrum efficiency
2. Flexible allocation of channel resources to achieve PTP, PTMT and multipoint-to-multipointtwo-way communication
3. Multiple channel bandwidth and a variety of modulation mode function
4. Flexible TDD slot allocation model to meet a single-frequency but multi-user access, not only save the spectrumbut also to reduce power consumption
5. Spectrum sensing, perception slot, upstream bandwidth sensing function
6. Strongdiffraction abilityand anti-multipath capability
7. High-sensitivity receiver. When receive level is -110dBm, can still ensure BER <10E-5and frame error rate <1%.Powerful error correction capability
8. Low PAPR, high power amplifier efficiency, low power consumption
9. Can transmitvideo audio and more signals synchronous, high speed. Velocity >600km/h.
10. Digital signal processing, a strong system of confidentiality, stability and reliability.

As its miniature volume, precision design, lightweight and easy to carry, it’s suitably used in short distance and long range air high speed wireless video data transmission purposes. Such as UAV, rotorcraft, micro UAV, drone, UGV, unmanned powered parachute, unmanned underwater vehicles boats, fire-fighting robot, unmanned ship, airship, USV, high iron, EMU, unmanned vehicles, unmanned vehicle and etc. Data transmission.
