Mbps Rate Transmission In the use of RF carrier signal transmission, using the Dbpsk method, DBPSK (differential binary phase shift keying) with two carriers of the digita

The micro-cell network built in the double-layer Wireless Access Network is a network with the topic of the wireless LAN system. The combination of macro-cell networks saves IP Address Allocation and solves network resources and costs. What is the principle? The AN04W-X024 Wireless LAN system of WRI is used in micro-cells. The wireless LAN system consists of an AP (Access Point), a wireless network adapter, and a wireless bridge. The AP of a wireless Access Point uses an omnidirectional coverag

the method is much faster than that of the 1-Mbps wireless network binary Differential Frequency Shift Keying DBPSK) modulation method. Because the signal quality keeps decreasing with the propagation distance, we have to adopt a compromise strategy in terms of speed and distance. Radio waves that spread in the air quickly decay, much greater than RF signals transmitted through cables. The FCC rules control the use of the 2. 4 GHz ISM band and the 5

Communication Algorithm 4: Nine debugging methods: theoretical error rate and actual error rate, and nine Error Rate 1. there are nine modulation methods, including BPSK, DBPSK, 2ASK, 2PSK, PSK, opsk, DQPSK, 16QAM, 64QAM, and theoretical error rate formula. You can view the book and use matlab to draw a picture to understand the theoretical error rate. 2. SNR :. Channel environment: AWGN Simulation process: modulation + AWGN + demodulation + BER Bas

This article describes in detail how to apply a wireless LAN system in a dual-network environment and how to establish a network in a community, I believe that reading this article will help you. The micro-cell network built in the double-layer Wireless Access Network is a network with the topic of the wireless LAN system. The combination of macro-cell networks saves IP Address Allocation and solves network resources and costs. What is the principle? The AN04W-X024 Wireless LAN system of WRI i
