Hopping Frequency Communication #2

AntiJamming Communication

RF Radios

XK-F311E is a Broadband wireless video and data transmission system. Two-way communication: Video+data camera control/drone control/telemetry 3 in 1. Point to Point; Point to Multi-Points relay mode, AdHoc networks

Supports transparent transmission protocol, which can transmit flight control data and other data information at the same time. The ground unit can interact data with ground station through serial port or network port (UDP / TCP). Support serial port and SBUs transparent transmission function.

  • Working frequency can be adjusted manually and automatically
  • The mapping mode is adjustable, including BPSK, QPSK, and 16QAM.
  • LDPC encoding rate is adjustable, supporting 1/2, 2/3, 3/4, 5/6.
  • TDD working mode.
  • Support Ethernet, serial port, SBUS/PPM.
  • Support AES128, AES256 encryption

XK-F311E FEATURES
