COFDM
- Strong anti-interference
- Anti-multipath fading
- LOS & NLOS operation (non-line-of-sight)
TDD & FDD
Both TDD (Time Division Duplex) and FDD (Frequency Division Duplex) are topologies used in advanced wireless communication. Compared to FDD, TDD wireless system needs only one frequency carrier in the transmitting and receiving path at different time-instant, that is, TDD wireless system’s channel is between the uplink and downlink paths reciprocal. And FDD wireless system need more than one frequency carriers for two way transmission, so it needs more RF module, such as Synthesizer, Local Oscillators, filters, to avoid interference. Thus, TDD wireless system more cost-effective than FDD because of requirement of less RF modules.
Network Structure
point to point, point to multi-point, multi-point to multi-point (Mesh networking)
Application
Small, light and portable as the transceiver is, TDD COFDM Ethernet transceiver is used in
- wireless Mesh networking and communication;
- short range high-speed wireless ground to ground NLOS transmission;
- long range high-speed UAV / air to ground mobile transmission;
- wireless audio video data transmission/ emergency communication;
- border security & defense;
- monitoring& surveillance.
