On 18 April 2024, it was proposed that this article be moved from Terrestrial Trunked Radio to TETRA. The result of the discussion was moved.

capitalization to emphasise the acronym

Ok, I can see that the use of this strange capitalization is there to emphasise the acronym, but I don't think it's appropriate for the title of the article (it makes it awkward to link for one thing). It should be reserved for the article body. Mintguy 12:49, 4 Aug 2003 (UTC)

Note on the radio aspects section

pi/4 is 45 degrees, not 22.5. i don't know which is correct for these radios, someone who knows more should correct this appropriately. Jk350 09:30, 6 June 2006 (UTC)[reply]

Correct. pi/4 is 45 degrees phase shift, since pi radians = 180 degrees. [User: tonygibbs16]

TMO vs DMO

The abbreviation DMO is expand as Direct Mode but what does TMO mean?

Trunked Mode Operation

about RATP TETRA MMI

This section appears to describe a particualr implementation (imagine if the GSM page only described Nokia handsets). Interesting though it is I suggest it is moved elsewhere (eg. the RATP page)

--Salocin-yel (talk) 14:58, 28 September 2009 (UTC)[reply]

Fully agree, both "A Virtual MMI for TETRA radio Terminal" and "RATP TETRA MMI" chapers are about specific applications, rather than about TETRA architecture. They were inserted about 2008-09-15 - 2008-09-19 and only been slightly cleanup since. So either removed, intergrated to RAPT page, or moved as separate page linked from RAPT main lav (talk) 18:51, 29 November 2009 (UTC)[reply]

Should clean up See Also / External links chapter

Instead of being internal links to related pages, "See Also" seems to have filled filled up with links to commercial operators in the field. Would suggest, after model GSM page, to:

Clean up everything from See Also chapter
1. Add internal links to companies doing TETRA networks itself (like EADS, Motorola, and more?)
Clean up most producers from External Links
1. Leave stuff like health report, and Motorola/Eads TETRA specific links

Now that TETRA has matured it has plenty of commercial entities; trying to include those would clutter up arcticle.

TETRA usage Table Broken

The table listing the usage by country is seriously messed up. I don't know how to fix that, please help! — Preceding unsigned comment added by 85.178.135.104 (talk) 11:40, 11 January 2013 (UTC)[reply]

Entry "ENTROPIA DIGITAL" for Croatia is most probably wrong here, not sure about the other one. --Marosi Gyula (talk) 20:27, 4 January 2014 (UTC)[reply]

Blacklisted Links Found on the Main Page

Cyberbot II has detected that page contains external links that have either been globally or locally blacklisted. Links tend to be blacklisted because they have a history of being spammed, or are highly innappropriate for Wikipedia. This, however, doesn't necessarily mean it's spam, or not a good link. If the link is a good link, you may wish to request whitelisting by going to the request page for whitelisting. If you feel the link being caught by the blacklist is a false positive, or no longer needed on the blacklist, you may request the regex be removed or altered at the blacklist request page. If the link is blacklisted globally and you feel the above applies you may request to whitelist it using the before mentioned request page, or request its removal, or alteration, at the request page on meta. When requesting whitelisting, be sure to supply the link to be whitelisted and wrap the link in nowiki tags. The whitelisting process can take its time so once a request has been filled out, you may set the invisible parameter on the tag to true. Please be aware that the bot will replace removed tags, and will remove misplaced tags regularly.

Below is a list of links that were found on the main page:

http://www.railway-technology.com/projects/shenyang-metro
Triggered by \brailway-technology\.com\b on the local blacklist

If you would like me to provide more information on the talk page, contact User:Cyberpower678 and ask him to program me with more info.

From your friendly hard working bot.—cyberbot II ^Notify_Online 11:17, 3 April 2014 (UTC)[reply]

Resolved This issue has been resolved, and I have therefore removed the tag, if not already done. No further action is necessary.—cyberbot II ^Notify_Online 19:29, 9 April 2014 (UTC)[reply]

External links modified

Hello fellow Wikipedians,

I have just added archive links to one external link on Terrestrial Trunked Radio. Please take a moment to review my edit. If necessary, add {{cbignore}} after the link to keep me from modifying it. Alternatively, you can add {{nobots|deny=InternetArchiveBot}} to keep me off the page altogether. I made the following changes:

Added archive https://web.archive.org/20101130172334/http://tetramou.com/tetramou.aspx?ID=6716 to http://www.tetramou.com/tetramou.aspx?ID=6716

When you have finished reviewing my changes, please set the checked parameter below to true to let others know.

The section "security vulnerabilities" needs review and adjustments

e.g.

- "AIE contains no authentication for the ciphertext, making malleability attacks possible." No 2G, 3G or 4G mobile network provides authentication of the ciphertext. TETRA is a 2G network. So this should be put in the right context.

- "TEA1 contains a secret reduction step tha..." There is no information that this has been done in the past to conform to export control regulations, as in all other mobile networks.

- TETRA is standardized by the ETSI TCCE. The TCCE published an statement on the vulnerabilites, that is not reference here, see: https://www.etsi.org/committee?id=2260

- The company Midnight Blue sells consulting services. This should be explained. Currently this Wikipedia article seems to acts as marketing instrument of the company.

"The cryptographic anonymization scheme is weak and can be partially reversed to track users."

There is no anonymization in mobile networks. There seems to be lacking knowledge, how mobile networks work. 77.188.28.242 (talk) 11:23, 4 November 2023 (UTC)[reply]

This whole section needs to be revised anyway.

As of Blackhat 2023, tetra is officially fully broken, no longer just vulnerable. Breaking TETRA After Decades in the Shadows TagKnife (talk) 21:16, 6 January 2024 (UTC)[reply]

Terrestrial Trunked Radio → TETRA – TETRA is the WP:COMMONNAME. Per MOS:ACROTITLE it should be the title, because it is primarily referred to by its acronym and the acronym is primarily used for this subject. It already redirects here. PhotographyEdits (talk) 12:50, 18 April 2024 (UTC)[reply]

Tx Power levels?

I may have missed it, but was there an explanation of power levels and other Tx characteristics of handsets, bases and repeaters? Seems pretty fundamental. Same with receiver specifications. Murat (talk) 16:41, 1 September 2024 (UTC)[reply]
