@HonkHase Hoffentlich wird die #Bundeswehr für ein #BwSATCOM-3 dann sowas wie #Iridium bzw. #IridiumNext fahren wollen, weil das geht mit überschaubarer Satellitenzahl sehr gut!
Ich rechne allerdings eher damit dass diese ne #TDRS-mäßige Konstellation für #UHFSATCOM & #Xband-#MILSATCOM aufsetzen werden...
Damn, the new TETRA radio I bought is not compatible with the Motorola TETRA CPS version that I have, so I cannot program it.
The radio is on MR2022.4
I'd need to import the release package or install the newer CPS.
If anyone got those files, let me know!
ROTFL: #Vodafone Germany claiming publicly that TETRA is baesd on 2G, and that 2G can only transport voice: https://newsroom.vodafone.de/politik-und-gesellschaft/virtuelles-sicherheitsnetz-fuer-polizei-und-rettungskraefte - don't they have anyone with a bit of technical clue proof-reading such public corporate communication? #telecom #gsm #3gpp #tetra
If anyone knows of job openings for some very experienced RF planners, TETRA, LTE, IBS, Outdoor please let me know. A bunch of guys I used to work with are looking for work as their current company is shutting down.
Philippinos who have worked for many years in Qatar, UAE and their home country. I've worked with them for several years and absolutely recommend them
They are willing to move country individually or as a group for the right job. Message me for details.

Interesting.
The TetraPack radio amateur TETRA network's core supports WAP and some folks have experimented with it.
But not for pushing images to an TETRA MS.
Now that would be amusing to see.
Or to just plop boykisser on some grumpy old mans TETRA radio over the network :D
How did I not know Hytera makes Tetra portable radios. Hmmm
@mischk
Hier noch einer zum Thema Funk, auf den ich persönlich mit großem Interesse warte: https://fahrplan.events.ccc.de/congress/2024/fahrplan/talk/9G97SZ/
Playing with the IFR 2968 a bit more this evening. Something I've realised is that it can't transmit the MCCH downlink during a call, even if the traffic channel and control channel are on the same carrier (in different slots) like a "real" base station would.
This leads to some odd behaviour when you do something like pressing "hang up" while listening to an incoming group call. The MS goes into No Service after a few seconds, and this confused me before. It actually makes sense though, because the IFR 2968 has stopped transmitting the MCCH in slot 1, continuing to transmit the TCH for the call instead (even though you've stopped listening). The MS thinks the control channel has gone away as a result.

Bei uns sind gerade Schulungen für die Einführung des #Digitalfunk bei der #Feuerwehr
Was den "Multiplikatoren" nicht gesagt wurde, daß der unberührbare Notfallknopf am Funkgerät auch aktiv ist, wenn das Funkgerät ausgeschaltet ist.
Es kam wie es kommen mußte, der Knopf 2s wurde gedrückt.
Die Leitstelle hatte so einen Notruf auch noch nicht gesehen und war leicht überfordert,
Wer von Leuten die #Tetra benutzen war das auch bekannt?
Suomenkin viranomaisten (mm. Puolustusvoimat ja poliisi) käyttämästä Virve / TETRA -viranomaisverkosta paljastui kesällä vakavia haavoittuvuuksia
Nyt TETRA-verkon salausalgoritmit on päätetty vihdoin avata public domainiksi, eli tutkijat pääsevät kunnolla kaivelemaan teknologiaa ja selvittämään, löytyykö järjestelmästä muita kriittisiä aukkoja.

LB: #Police in the #Netherlands have lost 2 200 #TETRA handheld #radio sets, which could easily fall into the hands of criminals (although presumably the lost ones could be stunned to prevent their registration to the network?)
This does potentially provide a ready source of kit which could be used to attempt cracking the TEA2 encryption (which Russia would definitely like to do as Ukraine are being donated TETRA radios for their soldiers by NATO countries)
Standards Body Considers #Uncloaking Secret #Encryption Algorithms
"The European standards body that created secret encryption algorithms for use in #TETRA radio communications is weighing whether to make new algorithms public, following backlash over its secrecy."

RE:TETRA project's aim is to get the cryptographic primitives underpinning the security of TETRA, to perform preliminary cryptanalysis on these primitives.

These guys shared their findings in DEFCON! There are vulnerabilities in TETRA infrastructure.

#cccamp23 https://events.ccc.de/camp/2023/hub/camp23/en/channels seems to be down. but I am able to keep watching stf going on about #OPRF . I hope the upcoming #AllCopsAreBroadcasting event, about obtaining the secret #TETRA primitives through legal means.
