The LISNR Radius SDK utilizes different Tone Profiles for Transmitters and Receivers while Transceiver Types are used for bi-directional Transceivers. Please see below for an overview:
Standard2: Long range, lower throughput. Optimized for reverberation and increased reliability. Typically used for Proximity Engagements, Broadcast and Second Screen implementations. Throughput of 33.3 bits/second, 66.6 bits/second (wideband). Maximum of 255 bytes.
PKAB2: Short range, high throughput. Optimized for closed distances. Typically used for Authentication, Payments, Access, and Security implementations. Throughput of 1000 bits/second, 2000 bits/second (wideband). Maximum of 3000 bytes.
Each transceiver type is composed of two tone profiles: one used for transmitting LISNR tones and one used for receiving LISNR tones. The throughputs, max payload size, etc for the utilized tone profiles in a transceiver type are the same as indicated above.
Transmit with standard2 wideband and receive with pkab2
Ex. Transmitting small identifier and receiving a confirmation payload from a nearby device
Transmit with pkab2 and receive with standard2 wideband
Ex. Transmitting a payment payload and receiving a confirmation response
Transmit with pkab2 and receive with pkab2 (higher and lower frequencies)
Ex. Transmitting an ATM transaction payload and receiving account balance
