MICRILOR, Inc.

Modulation technique: 16-ary Differential Bi-Orthogonal Keying (16-ary DBOK)

Key feature is dividing the 2.4-Ghz band into two frequency channels (instead of three used for the existing DSSS standard; this increases the signal bandwidth by a factor of three (32 Mchip/s), for:

Other features include:

Alantro | Harris Semiconductor | Lucent technologies | MicriLor | Rhaytheon | Top


Raytheon

Modulation Technique: Offset Quadrature Bi-Orthogonal Keying (OQBO)

This is a modification to the M-Mary Bi-Orthogonal Keying Modulation Technique proposed by Harris semiconductor. The modification allows operation with a saturated RF Transmitter Power Amplifier. This minimizes power consumption.
There are two data rates:

HDR (11 Mb/s)

MDR (6.975 Mb/s)
