UMTS in Europe

From traveling to Europe in the summer of 2007, I got the impression that UMTS coverage is almost complete, and GSM 2G networks are only maintained for old devices. --65.241.15.227 18:16, 10 September 2007 (UTC)

Network Bands

Would it make sense to list which band each network uses on this page? --Funkmaster 801 (talk) 10:15, 10 February 2008 (UTC)

Yes, absolutely, using the roman numerals for the band. Listing the frequency is confusing because it can be ambiguous whether this refers to the a) band's frequency "nickname" (which confusingly is sometimes taken from the uplink and sometimes from the downlink) or b) one of the uplink or downlink frequencies (rounded to an even number). This confusion is magnified by the fact that bands share frequencies, and even though they do, that does not create any sort of compatibility between them. 72.70.106.4 (talk) 10:45, 3 July 2009 (UTC)

Deducing carrier's network bands and interfaces based on the phones sold

For some operators it's impossible to find public and reliable information on what frequency bands they use. In that case I believe it's OK to deduce this information by analyzing the phones they sell. Ecbf (talk) 09:27, 2 January 2014 (UTC)

Plateau Wireless

As of 2014-01-02 they sell Caterpillar CAT B15 http://www.plateautel.com/wireless_details.asp?PhoneID=165 and Alcatel One Touch Scribe HD http://www.plateautel.com/wireless_details.asp?PhoneID=164 These are not LTE-capable smartphones so it's clear that they follow the US telecom marketing language: 4G = HSPA+, 4G LTE = LTE. It's pretty clear they have HSPA+ network. They also list FCC ids for the phones, for example the id for Caterpillar CAT B15 is ZL5B15AWS. According to the FCC files this phone supports WCDMA on 850/1700/1900 bands. Meanwhile Plateau Wireless list "4G: 850/1700/2100" on the phone page. For Alcatel One Touch Scribe HD they provide FCC id RAD330. This phone support WCDMA on 1700/1900 bands according to the FCC files. Meanwhile Plateau Wireless list "4G: 1700/2100" on the phone page. I think we can reasonably conclude that Plateau Wireless uses bands 850 and 1700/2100 (AWS) for HSPA+. Ecbf (talk) 09:27, 2 January 2014 (UTC)

Article name

I have moved the list back here from List of UMTS (W-CDMA) networks. The way I understand it, W-CDMA (UMTS) is currently proposed to be merged into the main UMTS article; thus I don't think it's helpful to split the list of networks into multiple parts. If those networks use different technologies, I'd suggest to add a corresponding column to the table so that readers interested only in a particular type of network can easily find those. Huon (talk) 20:22, 18 July 2014 (UTC)

Hi Huon. There are two things that were proposed:

Unfortunately both proposals were submitted at almost the same time. What might have caused confusion. The aim in general is to avoid several articles with the same content. Concerning the article List of UMTS (W-CDMA) networks the suffix (W-CDMA) was added to distinguish the list from the List of TD-SCDMA networks which is also a UMTS based technology. Please see my personal talk page for further explainations. Nightwalker-87 (talk) 10:10, 19 July 2014 (UTC)

The term W-CDMA (UMTS) is misleading. It suggest that UMTS is the same as WCDMA. I suggest to use the term UMTS-FDD or simply W-CDMA. If both should be mentioned, it should be UMTS-FDD (W-CDMA).
The current Wikipedia articles are misleading in that whenever mentioning a WCDMA network, it's mentioned as a UMTS network, while whenever mentioning a TD-SCDMA network, it is called a TD-SCDMA network. Thus it sounds as if UMTS is simply WCDMA, but the article itself indicates it includes TDD standards. --118.186.196.242 (talk) 20:24, 22 July 2014 (UTC)

Hi. First I would like to ask everybody to avoid Wikipedia:Edit warring at this article. I would appreciate to have a constructive discussion about the topic here.
For the first, please let me give some ackground information about the different 3G standards based on the 3GPP specification:
The UMTS specification includes a FDD and a TDD technology. The FDD technology is W-CDMA and the TDD technology is TD-CDMA also called UMTS-TDD (High Chip Rate (HCR)). The TDD part to be referred to as TD-CDMA never gained strong market adoption. (To say it more clearly: Apart from a very few deployments over more than 10 years, it was a complete market failure!) Because there are only a very few sources (left) for deployments and most deployments have been shut down by now, it does not make any sense to maintain a seperate list. Later TD-CDMA was redeveloped and improved by the Chinese Mobile Industry which resulted in the mobile standard TD-SCDMA. It was later added to the existing UMTS specification by 3GPP as a second TDD technology for UMTS (Low Chip Rate (LCR)). Although this TDD standard was belatedly added as part of the 3GPP specification for UMTS it is never referred to as "UMTS" oder "UMTS-TDD" in common technical language. Therefore I suggest to strongly addict to this common use.
In front of this background I also can't see any inconsistency with mainaining a seperate list for TD-SCDMA networks. On the other hand we might need a clearer indication in the name of this list here, that only UMTS networks with FDD technology are listed. Nightwalker-87 (talk) 11:21, 23 July 2014 (UTC)

I agree everything with you before the "Although this TDD standard was belatedly added..." statement. The inconsistency comes when you exclude TD-SCDMA from UMTS in one article while include it in another article. Whether or not a separate list for TD-SCDMA exist, this inconsistency persist. To resolve it, either remove TDD standards in the UMTS article and rewrite the article TD-SCDMA in a manner that it's not a substandard of WCDMA, or list all TDSCDMA networks in the UMTS list.

For common names, I rarely heard the term "TD-CDMA", instead, many refer it as "WCDMA-TDD". Should we also favor the term WCDMA-TDD? --114.132.245.174 (talk) 19:37, 1 August 2014 (UTC)

The current writing style is very misleading: the article reads, TD-SCDMA is a UMTS, which is a common name for WCDMA, standard. Yet common readers would understand it this way - TDSCDMA is a UMTS, i.e. WCDMA, network. When the reader refer this article to a second reader, he would say "TDSCDMA is a WCDMA standard". --114.132.245.174 (talk) 19:45, 1 August 2014 (UTC)

There is nothing misleading. TD-SCDMA is only mentioned in the 'see also' section so people even don't think about it plus you're the only who is complaining since a few days... Please do us a favour and stop with your obsession about TD-SCDMA! Nightwalker-87 actually set up the list of TD-SCDMA and instead of beeing grateful about it you're still whining around... MrCellular (talk) 20:26, 1 August 2014 (UTC)

Acutally the issue with 3GPP 3G-Standards is not that difficult: There is the "head" standard UMTS that includes the wireless access technologies / air interfaces W-CDMA (FDD) and TD-CDMA (TDD) (yes, this is the correct name). TD-CDMA was ralely deployed and never gained any widespread, also not in the technology oriented media. There used to be a "TD-CDMA Forum", a special interest group, composed of a few operators and technology manufactures that evangelised this TDD technology starting about the year 2005. This was not very sucessful and in the end the group dissolved after the Japanese company "IPMobile" went bankrupt in October 2007. As mentioned above, TD-SCDMA derived from TD-CDMA and was later "re-integrated" into the UMTS specification, but it is never referred to as beeing "UMTS". It is ever since being called "TD-SCDMA" (also in media; lay people call it "Chinese UMTS"). Further there has never been anything like "WCDMA-TDD". People that use this term seem to have no idea what they are talking about. W-CDMA is >solely< a FDD technology, which is completely INCOMPATIBLE to the TDD technique.
At last let me admit, that I really don't mind listening to other opinions and ideas and consider this helpful, but this is only useful and makes sense if people first READ and COLLECT INFORMATION about a topic before throwing around with words, terms and create obstacles that are not existing. Please keep this in mind. It is not the first time we experience this here on technology related wiki articles and lists. I don't want to count how many disimprovements active contibuters had to revert already - besides addional improvements (what is really important and necessary). Thanks for your cooperation ;-) @MrCellular: Thanks for the valuing words at the end of your comment. Nightwalker-87 (talk) 22:03, 1 August 2014 (UTC)

Merger proposal

Formal request has been received to merge: List of HSPA+ networks, List of HSDPA networks, and List of HSUPA networks to here; discussion here as well. Dated January 2016

  • Rationale: @Nightwalker-87: After the merger I propose a cleanup and proper integration of the existing content.
Merged articles according to WP:BOLD. Nightwalker-87 (talk) 21:24, 18 December 2016 (UTC)
  • Agreed, the articles should be merged. For the table format, I would follow List of LTE networks more closely:
Country Operator ƒ
(MHz) 		B Launch
date
UMTS
≤ 384 kbps 		Launch
date
HSDPA
≤ 14.4 Mbps 		Launch
date
HSUPA
≤ 5.76 Mbps 		Launch
date
HSPA+
≤ 21.1 Mbps 		Launch
date
MIMO, DC-HSPA, TC-HSPA
≤ 63.3 Mbps 		Notes

Then again, perhaps it is overkill to list the launch date for each technology level. It might be suffficient to have just a launch date and the highest level deployed together with the maximum speed:

Country Operator ƒ
(MHz) 		B Launch
date
 Max. downlink
speed (Mbps) 		Max. uplink
speed (Mbps) 		Notes

The corresponding UE categories would be more precise but they are almost impossible to find out (we would end up with a sea of question marks).

Drahtlos (talk) 17:22, 19 December 2016 (UTC)

  • Let's do it like this (compromise):
Operator Country 2100 MHz
Band 1 		900 MHz
Band 8 		Launch
date
UMTS
≤ 384 kbps 		Launch
date
HSPA+
≤ 21.1 Mbps 		Launch
date
DC-HSPA
≤ 42,2 Mbps 		Notes
Djezzy  Algeria Jun 2014 No Jun 2014 Jul 2014 (cites)

I would not introduce a single band column because more than 99% of all deployments are on either 900/2100 MHz or 850/1900 MHz. Exceptions can go into the Note-column. I believe that we will also end up with loads of question marks if we listed HSDPA and HSUPA. I think it's not worth it expanding the amount of information here. If we could concentrate all available information including the check of all sources - that would surely do. More efforts have already been made for 4G/LTE, with is ok, as it is the newer technology. TC-HSDPA is only inplemented in Turkey, so it's not reasonable to have a seperate column for it. A note would do here as well. Nightwalker-87 (talk) 20:37, 19 December 2016 (UTC)

Airtel Rwanda

Hi @Nightwalker-87:

Here is the extract from the current table. Have a look at the first and the last entry:

Airtel  Rwanda HSPA+
Airtel  Republic of Congo HSPA+
Orange  Reunion DC-HSDPA
SRR  Reunion DC-HSDPA
Airtel  Rwanda HSPA+

Only the retrieval date of the reference differs by a few days. Drahtlos (talk) 17:36, 29 January 2018 (UTC)

Ah, your're right. Didn't take note of that one in the same table, sorry. I thought there was a conincidence with my previous edit (MTN Rwanda). Thanks for the note. ;-) Nightwalker-87 (talk) 19:26, 29 January 2018 (UTC)

HSPA+

Why did you remove Botswana's networks from the list cause they'd have HSPA+ Gontle Galefite (talk) 11:34, 22 May 2018 (UTC) Gontle Galefite (talk) 11:34, 22 May 2018 (UTC)

Hi there. As stated in the edit description this was a maintennance edit as it appeared to stand against WP:VER. To maintain or raise the quality for wiki content it needs to be verifiable from official sources (please also see WP:SPS in this context). In general it is not the task of other editors to do research for verifiable sources for edits by secondary users which can turn out to be very time consuming. So ideally it would be like: Somebody wants to update content with new info, as he is sure that it is correct info, he does some research to find verifiable sources and then adds the new info together with the found citations. Hope this advice helps you along. With this in mind and by looking at your user talkpage history (which I believe is: https://wikivividly.com/wiki/User_talk:Gontle_Galefite), you will hardly experience that any your edits will be rolled back - no matter which article or list you are editing. Please don't hesitate to ask if you have any further questions. I'm also here to assist. ;-) Nightwalker-87 (talk) 12:06, 22 May 2018 (UTC)
