A short report of the sixteenth meeting of the CRplatform.NL held on January 29, 2016. The topic was:
The Internet of things: Applications, trends and potential impact on radio spectrum
Opening and welcome
13 persons attended the workshop. See the attendancelist for details.
During the review of the objectives and the workshops held on use-cases, Raymond Valk took the opportunity to mention the progress on the first workshop held in 2010 on the ECT terminal and the pre-standard use of Frequency-Hopping for the remote control of the mobile devices automatically transporting the containers. The conclusion of the workshop then was to replace the radio devices by an Enterprise GSM system. Raymond reported that two container terminals ECT Delta terminal and APM terminals Rotterdam deployed private LTE networks on different frequencies, all using Druid software. (APM-LTE is in operation / ECT-DT tested LTE on 3.7 GHz in a 3 months PoC with K&H / RA / Druid-Clarity, aswell in a 2 month PoC with KPN / VDC / Huawei eLTE). Raymond also made a brochure available on subject matter for a test site for driverless automotive transport.
Reflection on the 15th CR Workshop “LAA: Coexistence of LTE and Wi-Fi in 5GHz band and fair spectrum utilization”
The WiFi and LTE industries seem to have started meetings to resolve the issues.
Sietse van der Gaast, with support of Alexander ter Haar, gave a presentation of the study on subject matter, conducted on request of the Ministry of Economic Affairs. The presentation is available on the website. The full report is available on the website of the Ministry of Economic Affairs.
In the discussions one concluded that there would be a potential need for coordination so that mission critical messages receive priority over routine messages. The discussion pointed at the need for a variety of service levels and KPI’s.
Also the transmissions needed to be supported by a multiple of networks, including PAN, LAN, MAN and WAN networks. Licence exempt spectrum plays an important role to facilitate IoT on the various scales.
WRC 2015 by Peter Anker
The World Radio Conference 2015 came to the following conclusing that are relevant for this platform:
The allocation of the 700 MHZ in Region 1 (Europe, Africa and the Middle East) is confirmed. The band is now globally available for mobile broadband. However, the channeling arrangements are not completely the same across the globe.
The 1.4 GHz band (1427 – 1518 MHz) is now identified near globally for mobile broadband.
The band 3.4 – 3.6 GHz is now identified near globally for mobile broadband. The European effort to promote the 3.6-3.8 GHz for mobile broadband did not get much support. However, the 3.6-3.7 GHz band is now allocated for mobile broadband in the United States, Canada and Costa Rica.
There was recognising for the mobile broadband needs of the emergency sector. The WRC 2015 highlighted the 700 MHz and 800 MHz as global tuning ranges for public protection and disaster relief.
There was a strong push from the Arab countries to put IoT on the agenda for the next WRC. Most felt that there is no action from the WRC required. IoT was put already on the agenda of the ITU-R study groups through a Resolution of the Radio Assembly. The findings of these studies will be reported to the next WRC.
The decision was made to put spectrum for the next generation mobile broadband above 24 GHz on the agenda of the next WRC in 2019. The use of the 5 GHz range for RLAN (5150 – 5925 MHz) will also be on the agenda of the WRC 2019. The summary of the agenda for WRC-19 is available.
PMR XPO Keulen by Koen Mioulet
At the Professional Mobile Radio and Exposition conference held in Keulen, an idea about local agreements with regulators on sharing between mission critical and business critical usage surfaced. An example was LTETRA, a combination of LTE and Trunked Radio, TETRA.Mission critical functions. Hans Borgonjen is active in TETRA and Communications Critial Association (TCCA) to facilitate the forces interested in combining the two systems.
In France, with a culture of national monopolies for large institutions like airports, railways and power generation and distribution, aggregation between those verticals are already implementd. For instance some areas of the 700 MHZ band are allocated to those verticals like aiports and electricity company etc, in conjunction with Public Protection and Disaster Relief (PPDR).
Schiphol started research on such a vertical.
ETSI workshop on Future Radio Technologies – Air Interfaces, by Ben Smith
ETSI has organised this workshop in the activities of SoftwareDefinedRadio/CognitiveRadio. Software Defined Radio is supposed to be dead, at least as a marketing term, after its heavy hyping. LGE claimed that it is a failure for the commercial consumer application. Instead, one is speaking about “Reconfigurable Radio”. LSA is mentioned as an example as well as the development of a Radio Computer architecture. This defines a RadioVirtualMachine on which you can download apps for different radio characteristics. A development that causes concern at AT in relation to market surveillance. The program and the presentations are available at http://www.etsi.org/news-events/past-events/1005-workshop-on-future-radio-technologies-air-interfaces.
A concept of 5G, emphasizing that it is more than radio access, has been provided by Intel and Ericson in White Papers. http://www.ericsson.com/spotlight/cloud/blog/2015/02/17/5g-network-slices/ and https://communities.intel.com/community/itpeernetwork/datastack/blog/2015/04/27/5g-is-a-huge-opportunity-for-tems.
Some further “quotes”:
Even the director of ITU-R Francois Rancy was making a plea for more sharing, including LSA.
The topic of TV White Space is nearly dead too. Microsoft has indicated they have not much interest in it anymore.
The European Commission representative said they consider the 1200 MHz below 6GHz target for mobile as really sufficient.
Lots of support for more license free spectrum but no firm action to make it really free available.
Progress “Strategische Nota Frequentiebeleid” by Peter Anker
The ministry of Economic Affairs organises discussions with the stakeholders to get their views on various topics as input for the next Radio Spectrum Policy Memorandum. One of the most debated topics is the communication needs for specialized services, for both trade and industry and for public bodies (e.g. emergency services and municipalities).
Alle de Jong stated that Thales recently gave a presentation to the MoD together with TNO and UvA/CWI on a European proposal for a cognitive radio study for military use. The MoD will decide in May on their support as a sponsor. The MoD has made an inquiry with the Min EZ to co-sponsor this initiative as funding is a big problem for the MoD. Alle de Jong asked Thales whether they would be willing to share their presentation in this forum.
Summary and next steps
Alle de Jong will investigate whether Tales is still willing to provide a workshop on their proposal on cognitive radio.
