In the wireless data transmission system, the wireless transceiver chip is the core carrier of the technology. As the signal sending and receiving, modulation, and debugging, it plays an absolute core role. We will compare and analyze several Wireless Transceiver Chip Solutions.
1) CC1000 Wireless Transceiver Chip Solution
CC1000 is a single-chip programmable RF transceiver chip launched by Chipcon. Based on Chipcon's Smart RF technology, CC1000 can work in the ISM band (MHz ~ 1000 MHz ). CCl000

CM performs 64/256 QAM demodulation on the sent RF signal, and uses the RS technology (Reed_Solomon) for Error Correction. After the MPEG operation, the signal is converted to a format that complies with the Ethernet transmission protocol, it is sent to the terminal PC through the Cable Modem Ethernet port.After all downstream signals are sent to the terminal, the data signal sent by the user's co

WPA or WPA2 encryption, it can also be cracked, but the brute-force method is used to crack, that is, the software performs one-by-one guess, while WPA2 is more likely to be outputted.Defense measures against network attacks by others1. encrypted by WPA/WPA2-PSKHackers generally use dummies to crack software. They can only crack WEP-encrypted wireless signals. A Slightly advanced hacker will use packet capture tools to analyze the content in the data packets, to crack the WEP Key. But if you us

There are many benefits to using digitalization. The most obvious difference is that anti-interference performance is enhanced and encryption is easy.

Step 7: during this time period, make sure that a WPA-PSK client with a normal logon WLAN exists and that the client must be logged on to the WLAN, in other words, airodump must capture the entire "Request/challenge/response" Process of the client logging on to the WLAN. Of course, the time required for success and success is not measured by the listening time, but determined by the amount of communication.
