ABD• Points of Agreement– Modulation scheme should admit multiple classes of receivers

• Transmitter based on deterministic pulse structures• Should allow reception by coherent, differentially-coherent (can be TR) and non-

coherent receivers• Provision for homogeneous operation when membership supports it

– Ternary modulation • Specific modulation format TBD

– Sub-banding:• Center of three bands is mandatory• Other two optional• Wider bandwidth (1.5 GHz+) concentric with center band is optional• CDMA within frequency bands

– Harmonic chip rate – integer relationship between center frequency and chip rate • Consider ways to avoid Japanese UNII band (shift band lower)

– Integer-plus-half is also proposed, some concerns with DC balance– Maintain 3.1 corner

• Constant PRF is desired as possible

– Specific band plan - TBD– Cost effective reference frequency with appropriate PPM

• Specific frequency and tolerance is TBD

– Potential for optional chirp mode (at best, if and where allowed)

Slide 7

Specific Mandatory/Option Breakdown• As noted on previous slide• Mandatory

– ~500 center band • AM of 3.1-4.9 is 3.975• GM of 3.1-4.9 is 3.877• Center band frequency is TBD, but must be in [3.85 to 4.05]

• Optional– 2 additional 500 MHz bands for FDM – center frequencies TBD– Wideband concentric with center specified above– Sub-GHz band– Chirp of some form (could be 2.4 GHz band – Merger E)– Non-coherent for homogeneous network (Merger C)– Add TH as additional SOP mechanism– Add chirp specifically for UWB as SOP mechanism– Add specific optional band > 6 GHz with guaranteed >1.5GHz BW– Support mode for higher data rates (few to 10 Mbps)

• Other issues– Desire to have common packet for communications and ranging if possible– Multiple (2-few) PRF in band
