Massive Multi-Channel Demodulation (M2CD)
Excerpt From Introduction to Wireless Threat Intelligence Webinar
CTO Dr. Brett Walkenhorst Explains Massive Multi-Channel Demodulation (M2CD)
In this excerpt from the webinar, CTO Dr. Brett Walkenhorst talks about "massive multi-channel demodulation,". A lesser-known element of Bluetooth Low Energy (BLE) technology is addressed by this function. BLE uses forty channels in the spectrum, three of which are used for advertising. It is difficult to keep an eye on all traffic because devices connect and converse on the remaining thirty-seven channels, even though the majority of sniffers concentrate on these advertising channels. Bastille's method uses RF sensors to record the whole spectrum. On the backend, the data is then demodulated, decoded, and disambiguated to locate and identify each device on a network separately.
