  11. 11. 11 Non-confidential – Public © eXplanoTech Ltd. Huawei’s vision of 4.5G Huawei to finalise '4.5G' branding by Q1, commercialise in 2016 21st November 2014: Huawei said it will finalise the name of the emerging technology between 4G and 5G, which it is currently calling 4.5G, in the first quarter of 2015 and targets launching commercial products in 2016… “But we think it’s not that important what you call it. It could be 4GX, 4G+ or 4G B.” EE exec takes swipe at 4.5G “hype” 22nd October 2014: Mansoor Hanif, director of RAN development and programmes for UK number one operator EE, said there is “a lot of confusion out there” about the industry’s latest buzz-phrase, 4.5G. … “To some people, 4.5G is the combination of 4G plus Wi-Fi aggregated, to some people it’s something like that but closer to 5G. Each partner, each vendor, each operator has their own view. Vodafone in one presentation said that 4.5G refers to carrier aggregation,” he said.
  12. 12. Pre-5G ZTE to launch 'pre-5G' base station next year 23rd December, 2014: Chinese vendor ZTE has said it plans to launch a ‘pre- 5G’ testing base station in 2015, commercial use of which will be possible in 2016, following tests and adjustment. Pre-5G technology is a concept the company first proposed at a summit in Amsterdam at a time when industry insiders said 5G technology would not be deployed in the market before 2020. 12

When those are combined, that will be 5G as far as I’m concerned” - Michael Peeters, CTO of Alcatel- Lucent’s wireless business unit Source: 5G Reality Check – Mobile Europe, Dec. 2014 16 Non-confidential – Public © eXplanoTech Ltd. Conflicting views on 5G #1
  17. 17. “We believe OFDM, which we’ve inherited from LTE, is the best combination with MIMO. We don’t see a strong motivation at this point in time to walk away from OFDM because it has in- built flavour that can easily support a high number of antennas, as well as being cost and energy efficient, which will outweigh the little performance you gain from the other waveforms.” - Peter Merz, Head of Radio Systems, Technology and Innovation at Nokia Networks.

  18. 18. “In new frequency bands, perhaps around 6GHz, we think we’ll see allocations of much wider bandwidth, perhaps hundreds of MHz, so we’re looking at some variant of access technologies, but not too unlike what we have in LTE today, yes, there might be some things we do to OFDM in higher frequencies – to optimise it for higher bandwidth and reduce latency – but we think the basic modulation scheme will be the same.” - Dr. Håkan Andersson, Head of 5G Product Strategy, Radio Business Unit, Ericsson Source: 5G Reality Check – Mobile Europe, Dec. 2014 18 Non-confidential – Public © eXplanoTech Ltd.

That's two years ahead of when commercial 5G is expected to be available… NTT Docomo names suppliers for 5G trials; targets 2020 commercial launch 08/05/14: NTT Docomo, Japan’s biggest mobile operator, announced it is working with six suppliers to conduct various “experimental trials” for 5G involving higher frequency bands than those used for existing mobile technologies. SK Telecom teams with Nokia on 5G demo slated for 2018 Jan 21, 2015: The race to be the first to demonstrate and launch 5G is heating up. The latest entrant is SK Telecom which announced today that it has signed a memorandum of understanding (MOU) with Nokia to conduct joint research and development on 5G with the ultimate goal of demonstrating the technology in 2018 and commercially launching it in 2020. Samsung aims to debut 5G at 2018 Olympics October 22, 2014: Samsung aims to launch 5G-based products in time for the 2018 Winter Olympic Games in PyeongChang. Speaking at the ITU's 5G Global Summit, Samsung head of communications research Cheun Kyung-whoon said the PyeongChang Winter Olympics and the Tokyo Summer Olympics in 2020 will be an ideal time to showcase 5G technology, the Korea Herald said.
