All, The various versions of the proposed drafts of the PAWS protocol tended to distinguish between "device location" and "antenna height".
I think we should combine them into a single 3-D location of the radiation center of (the antenna of) the device. Does that sound right? The proposed draft-vchen-paws-protocol-00 defines the following parameters for location and height: latitude longitude locationUncertainty locationConfidence height heightType heightUncertainty This is very close to the fields defined by RFC 6225, which has the parameters: latitude latitudeUncertainty longitude longitudeUncertainty altitude altitudeUncertainty altitudeType Should PAWS reference RFC 6225 and list the following differences? - The "altitudeType" should be "above means sea level" (WGS84) or "above ground", instead of the ones defined in the RFC. - Add confidence values along each axis. If this acceptable, then we can think about defining JSON encoding of RFC 6225 for use by PAWS. Thanks. -- -vince
