(pest) asciilifeform: http://logs.bitdash.io/pest/2023-09-27#1030522 << fundamental misunderstanding of the concept, asciilifeform suspects. the notion of uwb is that 'when to watch for the pulse' is part of the key, and anyone w/out the latter simply sees noise indistinct from thermal background

(pest) crtdaydreams[asciilifeform]: maybe with a certain tolerance, your error correcting code might be able to handle maybe 3 different peers broadcasting to you at different thresholds on the uwb shortwave spectrum on a single reciever
(pest) crtdaydreams[asciilifeform]: there is a very small pool of viable noise/gate thresholds that account for noise and variation within uwb

(asciilifeform) vex: Yeah, I'm not too sure how your undectectable uwb theory works
(asciilifeform) asciilifeform not presently working on uwb, as has no one to uwb with
(asciilifeform) asciilifeform: considering that whole point is 'aint receivable by folx w/out the key', not much point in reich license. instead, learn the req'd physics, you won't be building a uwb w/out pretty good grasp
(asciilifeform) asciilifeform: vex: he was prolly interested in the uwb thing.
(asciilifeform) asciilifeform: ( in the hypothetical 'uwb pest' -- erry msg you send potentially demasks yer position and brings gestapo closer )
(asciilifeform) asciilifeform: ( this incidentally illustrates (entire class of) unsolved problems in re hypothetical 'uwb radio pest' )
(asciilifeform) asciilifeform: vex: uwb antenna gotta be compass oriented, and not erected at asciilifeform's new pad yet, 1st 'what direction' lol
(asciilifeform) dulapbot: Logged on 2020-04-27 23:24:36 asciilifeform: roughly speaking, 'uwb' over 0-30Mhz .
(asciilifeform) signpost: the uwb item is also on my mind, but I didn't want to stack too many skypies at once
(asciilifeform) dulapbot: Logged on 2021-09-01 16:35:56 asciilifeform: signpost: imho even to ~demonstrate~ uninterdictable uwb across planet, would cool the ardour of the 'internet of the future' types, at minimal expense.

(asciilifeform) dulapbot: Logged on 2021-09-30 21:04:56 asciilifeform: gotta get the uwb-hf derivations to signpost before folds.
(asciilifeform) vex 'd like to see uwb-hf derivations also. Fully cognisent of the powers radya plice hold.

(asciilifeform) asciilifeform still has massive dipole antenna in crate, and buncha uwb stuff which never tested
(asciilifeform) asciilifeform: roughly speaking, 'uwb' over 0-30Mhz .
(asciilifeform) asciilifeform: superkuh: what, btw, is wrong w/ e.g. terminated folded dipole, for uwb ? worx fine for hf, and easily disguised as, say, clothesline .
(asciilifeform) asciilifeform: superkuh: very interesting, imho, your www, e.g. the uwb antennae experiments. (i take it you aren't very interested in the hf band tho?)
(trilema) asciilifeform: https://sc01.alicdn.com/kf/HTB1owCvKpXXXXXmXVXXq6xXFXXX1/Antrad-10-directional-UWB-antenna-6-8.jpg << 6GHz item, pocket-sized. not so simple to scale up, 2x2metre pcb is not off the shelf item )
(trilema) asciilifeform: rounding off the uwb thread, for the l0gz : the antennae are the only nontrivial part. given as you do not actually need the sub-nanosecond pulses that are the subj of the 9000 dissertations littering the net, if you dun intend to kowtow to the 'fcc uwb regulatory' crapola.
(trilema) asciilifeform: usg phased array radar ? they're uwb, yes, but for >10GHz
(trilema) asciilifeform: lulzily enuff, found $subj during dig for whether anybody ever built a uwb antenna for hf ( 0-30MHz ). ( spoiler : nobody, publicly, as It Would Be Wrong (tm)(r) per hitler decree )
(trilema) asciilifeform: meanwhile, in re earlier lulzthread , 'Freescale and Motorola decided to pull out of the UWB forum in 2006 ... If one searches for XS110 chipset today then the answer at Freescale website (https://www.nxp.com) is that “Page Not Found”'

(trilema) asciilifeform: mprisoned' uwb to a uselessly short wavelength ( 2-4GHz, with a dip at 3 to 'avoid interfere with gps' ). the academitards naturally bent over backwards , killing whole forest printing paperola re 'optimal fcc-compliant gaussian pulse generation', some konsoomer crud was sold with 'uwb' to transmit vga over 3-4 metres in a room, and that was that.
