The real kicker is the last line. T-mobile can software upgrade its LTE equipment to 5G:
> The partnership with Ericsson means that T-Mobile’s already installed base of Ericsson Radio System radios will be able to run 5G NR with a remote software installation.
- StudentStuff 8y agoEricsson was/is Intel's large foundry client, but with the 10nm delays and 14nm being thoroughly booked with x86-64 and LTE modems for Apple, there isn't room for Ericsson to produce new chips on modern nodes. Worse yet, I hear Ericsson designed specifically for Intel 10nm, which leaves them up a creek for the next few years. A firmware update to make existing hardware have a longer lifespan and help Ericsson to retain their clients was likely the only out here. If Ericsson had the new chips they were planning on, this firmware update would be much more expensive and less probable to actually see carriers taking them up on it.
- ksec 8y ago>Ericsson was/is Intel's large foundry client That is actually Nokia. Not Ericsson
- kingosticks 8y agoDo either of you have an actual source?
- StudentStuff 8y agoDefinitely! https://semiaccurate.com/2018/07/02/intel-custom-foundrys-10nm-meltdown-is-crushing-a-20b-market-cap-tech-giant/ https://semiaccurate.com/2018/07/02/intel-custom-foundrys-10...
- kingosticks 8y agoNowhere there does it actually confirm that it's Nokia or Ericsson (or anyone else for that matter).
- StudentStuff 8y agoIts definitely Ericsson, they admitted to it in their recent filings: https://semiaccurate.com/2018/08/30/update-to-intel-custom-foundry-10nm-customer-meltdown/ https://semiaccurate.com/2018/08/30/update-to-intel-custom-f...
- kingosticks 8y agoIs there a link for the filing? I hadn't seen that update but it's still just rumours!
- StudentStuff 8y agoThere are a few links in the subscribers only part of the article that compare the last two filings. IIRC these articles age out after a certain period, check back in 46 days?
- StudentStuff 8y agoNope, its Ericsson, and Intel fucked them over pretty badly. All of Ericsson's newer chips were designed for 10nm, which doesn't work & Intel is full up on 14nm. Firmware updates to existing hardware and rebrands of existing chips are all Ericsson has to retain customers until they can either get another fab to build their chip (2 to 3 years from now), or Intel sorts out the yield issues on 10nm. https://semiaccurate.com/2018/07/02/intel-custom-foundrys-10nm-meltdown-is-crushing-a-20b-market-cap-tech-giant/ https://semiaccurate.com/2018/07/02/intel-custom-foundrys-10...
- ksec 8y agoI mean like... For Christ Sake. You take SemiAccruate as reliable sources, and even if the rumour were right. Ericsson was / is never disclosed as an Intel Custom Foundry Partner. The only self disclosed Telcom Equipment manufacturer using Intel 10nm is Nokia, and BTW where is the NOKIA bankrupt and "no way out" Seriously, this is HN, not Reddit.
- StudentStuff 8y agoSemiAccurate tends to be fairly on point, they do have a heavy slant against anyone that isn't on the GNU/Linux software support train. FYI, Ericsson admitted to this silicon problem negatively impacting them recently: https://semiaccurate.com/2018/08/30/update-to-intel-custom-foundry-10nm-customer-meltdown/ https://semiaccurate.com/2018/08/30/update-to-intel-custom-f...
- NKosmatos 8y agoThat's the good thing with almost all telecom equipment by Ericsson and their big advantage. Remote software update/upgrade while in operation with almost zero down time and also the ability to live/actively patch the running code.
- StudentStuff 8y agoIt is one of the core features of Erlang (a language developed by Ericsson), being able to rewrite code in production, with errors/crashes that break one thread not affecting another. Obligatory link to Erlang: The Movie (10min)- https://www.youtube.com/watch?v=xrIjfIjssLE https://www.youtube.com/watch?v=xrIjfIjssLE Note that they start crashing things in Erlang around minute 7, and fix them shortly thereafter. Meanwhile, their setup keeps calls that weren't directly involved in the crash alive and running unaffected.
- Matrixik 8y agoWell, great for Erlang. But this hardware is not running on Erlang but on C++. Erlang is used for testing.
- StudentStuff 8y agoSource? Ericsson themselves state that Erlang is a backbone of LTE, with "Many smartphones are connected for data transfer using Erlang software.". Seeing as Ericsson doesn't make cell phones, this would directly imply that critical portions of their base station software are written in Erlang. https://www.ericsson.com/en/news/2014/12/inside-erlang--creator-joe-armstrong-tells-his-story https://www.ericsson.com/en/news/2014/12/inside-erlang--crea...
- Matrixik 8y agoI was working on the code for mobile nodes, 3G and 4G. C++ with RSARTE (IBM plugin for Eclipse for Real-Time Applications) [1]. I left but my friends started working on 5G where looks like they want to get rid of RSARTE and use clean C++. At some point of time some people in Sweden started looking into rewriting it in Erlang but after around 1 year it was dropped, don't remember why.
