3.1 Main Features:
ToneLock security feature - LISNR now offers hands-on and hands-off Tonelock on payloads. Including a time based payload that expires after a 30 second time step.
Encryption security feature - LISNR now offers hands-off AES256 encryption process for all transmitted payloads. LISNR handles the key management process.
New Zone266 Tone Profile - New high throughput zone tone profile offers transmission distance up to 10 feet with 266 bits per second throughput.
3.0 Main Features:
Tone failed and Tone presence (beginning of a Tone) event notification - see additional article
Use of multiple channel(s) for broadcasting unique payloads or using separate tone profiles simultaneously - see additional article
Expanded set of tone profiles available for bidirectional/Transceiver implementations
Tone Profiles re-named:
Standard2 -> (deprecated)
Standard2_wideband -> Zone66
PKAB2 -> Point1000
PKAB2_wideband -> Point2000
2.0 Main Features:

PKAB2
PKAB2_wideband
Bi-directional ultrasonic data transmission, sending and receiving on non-overlapping frequency channels (1:1) - Transceiver
Transceiver Types:

Transmitters
Single Transmit functionality
Beaconing Transmit functionality
repeat payload transmission until stop called explicitly
Receivers
Detected tones report values for SNR (signal to noise ratio - indicates amount of interfering noise relative to the received strength of the tone) as well as Header/Payload EVM (error vector magnitude - indicates how challenging it was for the tone to be received)
