Good evening Nokia team, great pleasure to ask one more question

Hello,
That is a great question indeed especially given the media coverage of the subject. There are a couple of subjects here that need to be answer, but to briefly sum it up:
mmWave is new for telecom, but not new to the world - the same frequencies have been used for decades in other branches of industry like radars or satellite TV. After all those years there is literally zero evidence suggesting mmWaves are any more dangerous than a sub6G frequencies.

Also keep in mind that due to a massive-mimo beamforming the actual amount of radiated power hitting uninvolved bystanders is much, much lower than in 4G/4,5G solutions

13 October, 2020 14:51

So from the media perspective, the mmWave frequencies have little or no effect to bystanders

13 October, 2020 14:52

Like they portray it to be

We've been living with that kind of radiation for the better pat of our lives (or all our lives depending on the age) and there's no real evidence that it could be harmful to humans. That being said please keep in mind that the actual power transmitted by a BTS is typically under 100W right at the base station and dropping significantly with range. There's a standard called SAR that actually measures and points out a safe distance from anything that radiates. A separate value is given for an incidental exposure and a constant exposure. I've never seen any NOKIA's base station that would not be safe even to the person standing right next to it.

Nokia Poland - we cooperate with Universities, listen to professors voices, sceptic voices, read articles (real scientific articles), measure our signals all the times, respect regulations. Me, as a engineer spending long hours in laboratory (and as a PhD student), I feel safe and I didn't find any "real" reason to be scared.

Great to hear. I'm looking at taking certifications on 5G prior to joining Nokia

13 October, 2020 14:58

I also learnt Nokia deployed 5G in South Korea for SKT, how has been the performance and feedback from MNO (customer)

Hello Gareth, Thanks for your question, Nokia continuously investing in R&D to build the best E2E 5G networks for consumers and enterprises. We do have different types of 5G solutions that can address different 5G use cases considering their related ROI. Thanks to check more details here https://www.nokia.com/networks/5g/ and I will be interested to understand more the specific 5G use case you are referring to and its ROI to better answer your question.

Yes Dara, You are right! a lot of work need to be done to secure the data generated on the different 5G network layers and also securing the large number of devices (including IoT devices) that will access the 5G networks. You will find some interesting insights about 5G security in "Nokia Threat intelligence report"

Hi Ipsit S.,
It depends on the team you work for ;)
There are many departments and teams within 5G. If you are interested in "5G wireless" I can say something about my department - RRM (Radio Resource Management).
And my work is:
- more less 50% remotely
- feature I am in charge of, online meetings with developers, specifications etc...
- sometimes in laboratory with test base stations and various 5G phones (prototype and production devices)
- tests projecting, test plan writing, test execution, test environment building
- handling many small and big issues (software bugs, phones problems, environmental issues...)
So: working with software, hardware, test ware, and other teams.
I simply like it ;)

Hi Sachin P.,
Of course there are SW improvements - that's why it take years and it's called 5G instead of 4.9G ;)
1. 5G uses OFDMA like 4G
2. Control information sent between phone and base station are different. For example - for tracking the phone and handle beam forming another control data have to be transmitted.
3. 5G has lots of new features that let, for example 2 phone sharing one slot or to increase number of phones connected or to handle many phones better way.
I can recommend you this document to know more about it:

Nokia's industry-leading small cells portfolio includes a wide range of micro and pico products designed to seamlessly interact with macro LTE solutions. with 5G in the high-frequency spectrum bands, the need for the small cells will go up since high-frequency bands can be interrupted very easily. The operators will need to install more small cells to provide the same range of coverage for 5G that they did for 3G/4G with a lesser number of small cells

Hi, Anzar, thanks for the question. Cybersecurity is important and central topic for 5G system. 5G enables networks to be used in exciting new ways, but the growing variety of new devices and applications operating over the same network put security and privacy considerations front and center. 5G networks will connect devices that are critical to wider infrastructure, so data protection and access management features must be embedded in 5G solutions. 5G will also be a key enabler for the development of a digital economy and society, making security concerns everyone’s business, including organizations such as ISO, IEC, NIS, governements and others. Nokia has already played an important role in securing critical networks for more than 15 years and our technologies and expertise can help protect 5G networks and services in the future. More than 500 security projects worldwide already rely on Nokia and we regularly leverage our work in security standards forums to design solutions that fully address the security requirements of complex networks. Hope it's helpful.

Hi Rukshan! There are several areas in which C/C++ is used in Nokia R&D. It can be related to firmware, software development, modeling, verification, emulation. So, it really depends on which part of the project you would be working on. The important highlight is that there is definitely demand for these skills.

Hi;
5G is not only high frequency. 5G operates on frequencies from 400 MHz, means lower then usual 2G. This electromagnetic wave can travel many kilometers.
Of course if we operate on millimeter waves (for example frequencies of 37 GHz) network cell range is small.

Hi, thank you for the question. If I understood you right, you would like to know how 5G is being supported by Nokia and the role of various teams in Nokia. So, as we know 5G is the latest big technology that is expected to transform the world across industries and verticals. As Nokia is a network equipment supplier to both CSP (Communication service providers) and Enterprises (like Mining, ports), we engage with the customer proactively as well as responding to RFPs (Request for Proposals / 5G tenders). Our Nokia R&D has built world-class 5G products and solutions portfolio and it is supported by product management teams. There are 3 Business groups and various portfolio across these 3 BGs are offered as a part of 5G. Towards the customers, we have Sales teams (called Customer experience) as well as RBCs (Regional Business Centers) who try to meet all customer requirements. All this is assisted by pre-Sales, Bid management and other central functions. Usually, there is a customer demo and pilot first before commercial launch. We have been very successful already with multiple customers across the globe.
Hope this answers your question. I would be happy to explain further if necessary. I wish you the very best.

Thank you for the question.

The mobile network growth may see a slight decline during this year. Nokia's share may continue to grow, getting more market share.

The growth of traditional tower infrastructure for 5G may be relatively reduced as most of the MNOs have already established their 5G coverage. Now, as we move further, the requirement will come from the capacity perspective and mostly will be addressed through indoor infra solutions/small cells. EDGE-cloud infra will also play a pivotal role in addressing the capacity and quality requirements of different 5G services. This will create further fiber capacity enhancement.

As per GMI (Global Market Insights) Dec 2022 report, a 6% CAGR is projected between 2023 to 2032. The main growth drivers are 5G commercialization, the adaptation of software-defined networks (SDN), increasing demand for data center consolidation, and server virtualization. Minimizing the carbon footprint will be another important aspect that will drive the future landscape of the telecom infra segment. I hope this helps.

Thanks a lot Mr. Dharmendra S. for a detailed perspective. If I paraphrase it, traditional 5G infra growth may be slow in future but there are some factors which could keep driving the growth like 5G commercialization, SDN, data center consolidation etc. These could be addressed using small cells and EDGE-cloud infra.
I assume that the 6% CAGR projection figure you quoted is for the entire 5G business or is it for 5G infra alone?
Thanks again.

05 February, 2024 11:08

This includes entire Network infrastructure and services for both segments (communication service providers and Enterprise).
