5G will require cooperative approaches to spectrum sharing – EC

5G will require new approaches to spectrum sharing, in particular in bands below 6GHz, and could see vertical industries become MVNOs.

The November 2015 World Radiocommunication Conference (WRC15) came to the conclusion that IMT2020, that is 5G, will require spectrum allocations below 6 GHz and above 6 GHz. A new report supported by the European Commission (EC) has found that 5G will require cooperative approaches to spectrum sharing in all bands, in order to address future spectrum requirements. “Analysis showed there is a requirement to share spectrum in all the spectrum ranges, particularly in bands below 6 GHz where it is beneficial to share as much spectrum as possible,” the report stated.

In addition to today’s exclusive spectrum licensing, future spectrum sharing could use cooperative approaches, including concurrent shared access, licensed shared access, authorized shared access and license-exempt access, as follows:

• Concurrent shared access: multiple operators share access to the same portion of spectrum but in a coordinated and managed way.
• Licensed shared access:  incumbent-licensed users permit access to spectrum by way of a sub-license.
• Authorized shared access: spectrum that is unused by the incumbent can be used dynamically at any time and any location.
• License-exempt access:  generally authorized access to spectrum by devices compliant with industry standards for low emissions and types of spectrum access.

Vertical industries become MVNOs

In addition to network operators, spectrum sharing for 5G could involve vertical industries. In effect, vertical industries could become self-supplying mobile virtual network operators (MVNOs), the EC report says. And in fact, this is already happening. France’s Agurre, an association regrouping radio network users in the transportation industry, was granted shared access to prime 700 MHz spectrum blocks with the Public Protection and the Disaster Relief (PPDR) community. According to the EC report, this is the first time in Europe, and possibly the world, that a vertical industry negotiated shared access to sub 1 GHz spectrum.

5G deployment to cost $63 billion in 2020

The EC-supported report, conducted by InterDigital Europe, Real Wireless, Tech4i2 and Connect (Trinity College Dublin), estimated the cost of deploying 5G in the European Union’s 28 member states (EU28) will reach €56 billion ($63 billion) in 2020. From 2025 onwards, EU28 member states could benefit from 5G to the tune of €113.1 billion ($127 billion) annually, with trickle-down benefits from 5G investment totaling as much as €141 billion ($158 billion). A total of 2.4 million jobs could be created as a result of 5G deployment.

People: Håkan Eriksson tipped as top Ericsson board’s CEO candidate

Håkan Eriksson is today heading Ericsson’s operations in Australia and he has worked at Ericsson for the past 30 years. He has been reported by Swedish business paper Dagens Industri to be the candidate favored by the board of Ericsson to take over as CEO after Hans Vestberg. According to the paper, Eriksson is the only internal candidate on the list. Eriksson is said to have been instrumental in Ericsson’s past successes with 3G. He is 56, and studied in Sweden and at Stanford to become an engineer. He lacks a formal business education, the paper reports.

AI: Fujitsu starts selling AI-based city monitoring and parking management solutions

Japan-based Fujitsu announced the availability of new solutions for city monitoring and parking management using the company’s Human Centric AI Zinrai artificial intelligence (AI) and supercomputer technology. The city monitoring system, Citywide Surveillance, extracts a variety of data from surveillance camera images to give a real-time understanding of movements in a given urban environment. Parking identifies in real-time which parking spots are open.

Security: Expect more IoT DDoS attacks as infamous IoT botnet is publicly released

The source code powering the Internet of Things (IoT) botnet behind the recent, massive distributed denial of service (DDoS) attack against Krebsonsecurity.com  has been publicly released. Security expert Brian Krebs warns the internet could soon be flooded with new IoT DDoS attacks. Dubbed Mirai, the malware spreads to vulnerable devices by continuously scanning the Internet for IoT systems protected by factory default or hard-coded usernames and passwords, Krebs explained. Mirai is one of two dominant IoT malwares. Mirai’s competitor, dubbed Bashlight, is responsible for “enslaving” nearly one million devices, according to Level3 Communications. Rebooting infected systems allows to clean these up. To prevent the device from being immediately re-infected, its default password must be changed.

Connected car: Connected car production to reach 61 million in 2020

The production of cars equipped with built-in or tethered data connectivity will reach 61 million in 2020, growing from 12.4 million in 2016, according to new research by Gartner. The analyst firm also predicts that connected cars will drive demand for contextual information, including image detection and geolocation.
