One in 10 communications companies claim to have deployed 5G technology already, according to a recent survey (see: With 5G technology, the time is now).

Some parts of the 5G standard are close to being finalized, but nothing has been ratified yet. 

Furthermore, many of the constituent technologies (e.g., mmWave RF, beamforming, MIMO, etc.) are either new or not commonly used. SDN and NFV are considered critical enablers of the heightened utility and expanded flexibility that will be hallmarks of 5G networks.

The industry has a learning curve to climb. The recent set of announcements can be considered an indicator that the industry is beginning to surge up that slope.

    Do you need 5g connections to anything?

    Talk about the upcoming 5g connections is hot. But do consumers go so hot about new technology?

    For example, network companies and telecom operators have been pushing a lot of expectations for 5g technology. There is a current phase between 4g and 5g, which makes the market situation difficult.

    Mobile phones are already full of applications, and a large part of the day’s hours is spent watching the mobile screen. The connections are fast and all the facilities work smoothly.

    What if consumers do not feel that they need 5g or are they not willing to pay any more? Can it become a bottleneck for companies to grow in the future?

    “Whenever new technologies are introduced, the world will increase its efficiency, bringing more speed and more computing power.” The need for the world and the demand for faster telecommunications connections are not disappearing, “says Indyres CEO and analyst Mikael Rautanen .

    The first 5G phone will come next year

    Elisa announced today that it already has over gigabit data rates in a couple of well-defined locations in Finland. such 5G speeds require their own terminals and Qualcomm will promise the first 5G phone for developers next year.

    Qualcomm actually introduced its reference equipment earlier this month. It is based on the X50 modem circuit.

    The 5G demo was performed at Qualcomm’s San Diego Research Laboratory. There were several hundreds of megahertz carriers in operation that allowed total over gigabit data rates. The link was built on the Keysight Technologies UXM 5G platform.

    “The first 5G phone” is therefore really a test platform, but in any case built into the phone’s dimensions and shape.

    Commercial X50-based smartphones could be expected to launch in 2019.

    Why 5G is in trouble – and how to fix it: Commentary
    http://www.cablinginstall.com/articles/pt/2017/10/why-5g-is-in-trouble-and-how-to-fix-it-commentary.html?cmpid=enl_cim_cim_data_center_newsletter_2017-11-06

    I have a somewhat unconventional view of 5G. I just happen to believe it is the right one. It is trapped inside a category error about the nature of packet networking, and this means it is in trouble [...] 5G is making the network far more dynamic, without having the mathematics, models, methods or mechanisms to do the “high-frequency trading” [...] The whole industry is missing a core performance engineering skill: they can do (component) radio engineering, but not complete systems engineering. When you join all the bits, you don’t know what you get until you turn it on! The result will not be pretty.

    Why 5G Is in Trouble (and How to Fix It)
    http://www.circleid.com/posts/20171031_why_5g_is_in_trouble_and_how_to_fix_it/

    As such, 5G is attempting to both extend and transcend the present “undifferentiated data sludge” model of mobile broadband.

    Firstly, it pumps the “undrinkable” mucky bandwidth harder and faster, to give a modified version of what we have today with 4G. We will gloss over the minor miracle that needs to happen with backhaul, or that the mobility protocols today with 4G struggle when you get on the train (and 5G makes it worse).

    Secondly, its other goal is to deliver differentiated “drinkable” access for different enterprise cloud and industrial applications. This essentially is a generic version of the very specific VoLTE solution developed for voice telephony in 4G, extended to any cloud application. It can be expressed as being for low-latency applications, or packed in a variety of other guises.

    The conventional wisdom is that packet networks enable networked computing (“join devices”), and networks do “work”. As such, the job of the network is to forward as many packets as fast as possible, and what matters most is “speed”. 5G fits this.

    The unconventional wisdom is that packet networks enable interprocess communications (“join computations”), and networks don’t do “work”. As such, the job of the network is to trade resources around to deliver the “just right” quantity of quality to optimise the trade-offs of QoE risk.

    The former model is “pipe”, the latter is “futures and options trading”. The former works with TCP/IP, the latter needs new packet architectures (RINA). The former can extend radio network protocols from 2G, 3G and 4G; the latter needs new ones.

    The result will not be pretty.

    In particular, 5G is primarily delivering into the tail of the last S curve of generic unassured broadband Internet access; it is not on its present path fit-for-purpose for assured cloud application access (inc VR/AR and IoT), which is the new S curve of growth.

    Telephony is virtual reality. VoLTE wasn’t solving the problem of how to extend the life of the past; it was solving a corner case of how do we communicate in future. Understand this, and the future and fate of 5G makes more sense.

    The key question is whether 5G is aimed at extending the VoLTE part of 4G (fit-for-purpose voice) or improving the rest (purpose-for-fitness Internet access). It is trying to serve two strategic masters, the past and the future, at once.

    So, what to do about it? I see three key industry actions.

    Firstly, we need to narrow the intentional semantics. 5G is trying to do too many things.

    The focus of the generic broadband access should not be peak speed, or even “antipeak” latency under ideal conditions. It should be to establish a consistent quality floor under real-world conditions with graceful degradation in overload. That floor should be adjustable so that you can segment the market by quality.

    This is a precursor to a 6G, where the two sides of unassured and assured can be unified through a shared framework for managing the quality floor.

    Is 5G for real?
    https://www.edn.com/electronics-blogs/5g-waves/4459035/Is-5G-for-real-?utm_content=bufferee151&utm_medium=social&utm_source=twitter.com&utm_campaign=buffer

    Recently, a colleague asked me, “is 5G for real?” Not exactly the question that I was expecting, but there was something behind the question that gave me pause. Of course, 5G is not real—at least not yet—but that wasn’t the question. My colleague was really asking, “is 5G going to be as impactful as everyone anticipates?” Having been involved in the wireless industry for many years, I must admit to a certain fascination regarding 5G mainly due to the innovative technologies being proposed. But that’s a story for another day.

    The question probes deeper into the business impact. When I searched for “5G business impact” I was rewarded with a paper by IHS Markit that attempts to answer my colleague’s question. IHS Markit speculates that 5G will become a General-Purpose Technology (GPT), a development so impactful that it becomes a catalyst for socio-economic transformation.

    The Enhanced Mobile Broadband (EMBB) case is probably the most relatable as everyone wants higher data rates. Faster data can, however, give rise to new applications in augmented and virtual reality

    Massive Machine Type Communication (mMTC), on the other hand, attempts to connect billions of devices and incorporate wireless into many devices not previously connected and expand their utility. We’ve seen a glimpse of this opportunity today with new IoT deployments

    Intel has introduced its first commercial 5G modem circuitry. According to the company, they will enter the market in 5G terminals in mid-2019. Intel clearly wants Apple to reject Qualcomm modems in its upcoming 5G devices.

    Intel XMM 8000 supports both frequencies of less than 6 gigahertz and millimeter frequencies. The company says it could already play a 5G call with the XMM 8000 Series modem in the 28GHz range, which is the first 5G frequency in the US market, for example.

    At the same time Intel introduced a new LTT modem. The XMM 7760 chipset supports Class 19 LTE ​​speeds, and at best, data transfer can be up to 1.6 gigabits per second. The XMM 7760 is the fastest LTE modem circuit on the market. It will not be available until next year.

    Intel has already provided Apple’s modem circuits to the previous iPhone generation. Qualcomm has been supplying Apple’s circuits since 2011 and its 5G-X50 X50 modem is still the Intel chipset in the upcoming development.

    BT boss: Yeah, making a business case for 5G is hard
    Also, we’ve not delayed the spectrum auction. Anyway, Three started it!
    https://www.theregister.co.uk/2017/11/16/bt_boss_yeah_making_a_biz_case_for_5g_is_hard/

    Chief exec of BT, Gavin Patterson, has admitted the British telco is struggling to make a business case for 5G investment, given the huge costs of getting the network off the ground.

    Speaking at the Huawei Global Mobile Broadband Forum in London, Patterson said: “I talk to other CEOs around the world… and we’ve all been struggling a little bit to make the business case work.”

    He said the shift to 5G will involve “significant investment” and capital expenditure. “We’ve got to finish the job on 4G, and we’ve got to make sure we get the return on investment [on that].”

    The case for 4G was easier, as it was clear the technology would improve the poor internet experience of 3G, he said. “We’ve not found that yet on 5G.” While the transition to 5G will also create a better internet experience, it may not be until the Internet of Things takes off that new revenue streams are identified. “Finding the use cases is the biggest challenge we have at the moment.”
