Welcome to the OGC Electromagnetic Spectrum Domain Working Group (EM Spectrum DWG) (EMSpectrumDWG)* web

*NOTE: When this OGC Domain Working Group (DWG) was originally proposed, the initiating organizations were calling it the "SpectrumML DWG". The OGC Planning Committee requested a more generic DWG name – "EM Spectrum DWG" – to make this standard development effort more closely follow the OGC's usual naming procedures. In the future, after review of technical requirements, market needs and enlistment of appropriate experts, the participants in the now officially chartered OGC EM Spectrum DWG may choose to initiate a Standards Working Group to develop the standard. At that point, they may choose to call the standard "SpectrumML", in which case the Standards Working Group will be called the OGC SpectrumML Standards Working Group.

This OGC wiki is a web resource for an OGC Domain Working Group (DWG) that is discussing a proposed open standard conceptual data model* and derived digital encoding(s) for environmental electromagnetic field (EMF) data. " SpectrumML" is the tentative name for the proposed standard.

* A data model details how to encode real world ideas or objects to make them useful in computer systems. To be more specific: a conceptual electromagnetic field data model would enable the development of one or more implementable encoding standards specifying a common way of representing electromagnetic field data. Widespread use of such a standard would enable data to be created by many players and then published, discovered, assessed, shared, compared, aggregated, integrated, accessed, analyzed and used by many players in distributed computing environments.

This group convened for the first time at a SpectrumML Ad Hoc session on Thursday 23 June 2016 at the OGC Technical Committee meeting in Dublin, Ireland. See the minutes of that meeting below. At that session, the following OGC member representatives agreed to be Charter Members of the proposed working group. They included:

• Martin Desruisseaux, GEOMATYS

• Chuck Heazel, WiSC Enterprises

• Chris Little, UK Met Office

• Joan Maso, Universitat Autònoma de Barcelona (CREAF)

• Lance McKee, McKee Associates

Persuant to that meeting, Lance McKee drafted a charter for the proposed OGC Spectrum Model Language Domain Working Group. That charter was reviewed by the Charter Members. Revisions were made. The final draft of the charter is available at https://portal.opengeospatial.org/files/?artifact_id=71300.

A press release public request for comments on the charter was released in August 2016. Comments received were to be incorporated in the charter prior to the OGC Technical Committee meeting in Orlando, Florida, USA in September. (No comments were received.)

The second Ad Hoc session of the group convened again from 08:15-09:05 on Monday 19 September at the OGC Technical Committee meeting in Orlando, Florida, USA. Remote participation was available but no one called in. See minutes of this meeting below (below the minutes of the first Ad Hoc session.)

Two days after the Second Ad Hoc session, the Technical Committee voted at the Thursday 22 September 2016 Plenary Session to approve the OGC Spectrum Model Language Domain Working Group (SpectrumML DWG) Charter. (As mentioned in the note above, at the request of the Planning Committee, the group agreed to change the name of the DWG to "Electromagnetic Spectrum Domain Working Group" or "EM Spectrum DWG".)

EM Spectrum DWG initiators now include:

• Akinori Asahara – Hitachi, Ltd., Central Research Laboratory

• Martin Desruisseaux – GEOMATYS

• Chuck Heazel – WiSC Enterprises

• Siegbert Kunz – Fraunhofer-Gesellschaft

• Chris Little – UK Met Office

• Joan Masó – Universitat Autònoma de Barcelona (CREAF)

• Lance McKee – Consultant

• Jason Smith – Harris Corporation

• Prof. George Zalidis, Aristotle University of Thessaloniki, i-BEC

Two active participants then joined the group:

• Carey Beall
• Lucia Lovison

After the last meeting, Jesse Caulfield, CEO of Key Bridge, joined our collaboration via email. Key Bridge is a collaborator with the US Defense Spectrum Office and developer of the OpenSSRF reference software.

Work has now begun. The new DWG's members have begun to communicate by email, this wiki, and teleconference to discuss questions and issues. The group will start looking at use cases and start finding electrical engineers who can provide technical guidance and help develop a UML diagram.

An article on this topic by Lance McKee was posted on the EE Times blog on 16 September 2016: " RF Emissions Need Data Model".

--------------------------------

MINUTES - SpectrumML First Ad Hoc session on Thursday 23 June:

Lance McKee chaired the meeting. Those in attendance included: Greg Buehler, Martin Desruisseaux, Chuck Heazel, Chris Little, Joan Maso, Mark Reichardt and Kym Watson.

OGC members and non-members had been invited to attend, but no non-members joined the meeting. A SpectrumML Discussion Paper and set of slides had been drafted to provide a basis for discussion at the meeting. At the meeting, the ideas in the paper and slides were discussed. Discussion centered around:

1. The difficulty/simplicity of of developing such a standard. There are many electromagnetic field properties, but their SI units, relationships, and principles of interaction with the physical environment are already well understood.

2. Whether and how such a standard might be useful in resolving the following problems:

— Wireless communication signals sometimes interfere with Earth observations ( National Academy of Sciences, 2015) and with communication between satellites and ground stations. Similar problems exist in aviation. It is also likely that as near-field sensing (e.g. in smart cars) becomes common, such sensing may suffer from interference among many sensing systems in close proximity and perhaps also between such sensing systems and wireless communications systems.

— The multiplying and increasingly closely located IoT sources of radiofrequency emissions are on an electromagnetic compatibility collision course with the delicate, and soon to be ubiquitous, electronic devices of the IoT. ( IEEE Spectrum article, 2015). Also, the transition to distributed renewable energy sources brings with it inverters, mechanical generators and other equipment that may cause electromagnetic noise and pulses that can affect sensitive electronics. The proposed standard would be useful in monitoring, modeling and mitigating problems involving problematic environmental electromagnetic fields.

–– There may be use cases in the wireless communications industry. Adaptive modulation schemes and spectrum sharing may be areas in which the proposed standard would be useful. The proposed standard might also be useful in cell tower siting and small cell network deployment.

–– The proposed standard might be useful in ELINT and SIGINT, spectrometry, telescopy, astrophysics and other domains focused on electromagnetic fields.

3. There was general agreement that "SpectrumML" would be a good name for the proposed standard.

After discussion, a motion to draft a working group charter was made by Chuck Heazel and seconded by Chris Little. A vote was taken. There was unanimous consent that there is sufficient probable need for the standard to warrant drafting a charter for an OGC Spectrum Model Language Domain Working Group ( SpectrumML DWG).

The group committed to completing the draft charter and submitting it for Technical Committee (TC) review and comment in time for possible approval at the next TC meeting (September 2016 in Orlando). The charter will list the names of the working group's initiators. After approval, OGC members will be invited to join the EM Spectrum DWG and chairs of the DWG will be elected. Existence of the new group will be publicly announced. OGC is an open membership organization, and opportunities are provided for public comment and review.

The meeting adjourned.

MINUTES - Second SpectrumML Ad Hoc session 19 September 2016:

Lance McKee (consultant), Akinori Asahara (Hitachi, Ltd., Central Research Laboratory), Jason Smith (Harris Corporation), and Trevor Taylor (OGC) were present.

1. The chair noted that no comments were received in response to the RFC.

2. The chair presented history of outreach to date. Further outreach awaits discussion among WG members.

3. There was discussion about the charter approval vote to be held at the Technical Committee Plenary session on Thursday. All present agreed to seek approval. Members not present had indicated by their agreement to be charter members that they, too, wanted to seek approval. Chair noted that he would discuss and confirm procedure with Scott Simmons.

4. Planning first phase of work awaits TC approval and then email and/or teleconference discussion by group.

5. There was also discussion of main use cases, a nano-spatial use case of interest to Hitachi, and a potential new member. Akinori Asahara at Hitachi is interested in helping to develop a “nanoscale spatial data infrastructure” that conforms to OGC’s geospatial data infrastructure standards. This involves, for example, orientating tiny microcircuit-embedded antennas to the larger indoor/outdoor EMF environment.

Second Ad Hoc session ended.

• Lucia Lovison

Lance McKee chaired the meeting and kept the minutes. Trevor Taylor of OGC staff facilitated.

Session began with introductions.

Carey Beall spoke about his work in DISA. DISA provides a tool in use in the Pacific Command — “Mercury” — an open source tool from DISA used to coordinate frequencies on the spot during disasters. 45 countries in Pacific region use this to to share information.

Carey works with NATO countries, maintaining a spectrum standard for data exchange. The standard is used for frequency assignment and equipment certification. The temporal element becomes increasingly important with increased use of cognitive, or software defined, radio. (Their standard has been partially adopted by the White Space Consortium in the US, who who use cognitive radio technology to detect and expoit vacant spectrum.) The NATO std is SMADREF. The DOD std is OpenSSRF. Carey suggested that perhaps DISA did twenty years ago what this DWG aims to do. DISA also did NIEM. They’re involved in many different related activities.

Lucia Lovison deals with EO data for integration of time and space, especially for disasters in Latin America and Europe, and is focussed on standards from the OGC, IEEE and others.

There was a suggestion that a first step would be to do a literature review, to discover other standards. DISA did NIEM, for example, and OGC did a lot of work on Geo4NIEM. These are both related to the purpose of the EM Spectrum DWG.

Carey noted that the DISA people have concluded there is no overarching standard. You can’t model the whole universe. It’s better to have small subset of standards that can be easily changed. E.g., they find frequency assigments is one good domain. Equipment certification is another good domain. Monitored spectrum is a another different domain. All have different business processes.

Aki introduced discussion about tables of frequency allocations. ITU helps manage these agreements. In violent regions, however these allocation rules are not followed. Carey noted that a standard will help if we can nail down the temporal aspect. We’ll need a standard for sensing the radio environment and sensing holes to transmit through. It needs to be highly dynamic. There is no standard to handle that, particularly with software defined radio.

Chris Little provided information about current work in OGC involving temporal. The main calendar used is Gregorian, which uses leap seconds. We’ll need much better resolution, getting around the use of leap seconds. Work is being done in ISO and OGC for well known types (WKT) that will allow use of ISO timestamp (which is being revised), using international time, working out a way to sidestep leapseconds. So work in progress will be relevant to EM Spectrum work. Roger Lott and Mark Hedley are working on it. The calendars and CRS are well understood. A key issue is having a way of implementing the ISO standard so it will fail rather than pass errors.

It was noted, with reference to Chris’s comment, that it in addition to the literature review it would be good to keep a list of the other OGC WGs that are relevant: For temporal issues, it’s the OGC Temporal DWG and also the OGC TimeSeriesML Standards Working Group (SWG) (who are working together).

Lucia Lovison suggested it would benefit us to have people from IEEE involved. They’re been involved in spectrum for many years. Utility company’s are involved. Chris agreed, but IEEE contacts on Temporal DWG didn’t really engage. Also approache International Bureau of Weights and Measures (BIPM) but they didn’t want to engage. Chris suggested having the IEEE people who are interested to sign up to the OGC mailing list and wiki and join in the discussions. Lucia will ask them.

Carey re IEEE: The temporal aspect is nailed down in IEEE. The dynamic spectrum allocation has a working group with 3 or 4 standards out. Question is these two opposing points of view: Will dynamic spectrum allocation be done through a centralized system of “when can I emit?” or will it be dynamic -“I am sensing and I can tell when I must get out.”

Chris noted that a Central system won’t be scalable. But with a distributed system the problem is that nobody’s clocks are synchronized.

Carey - exactly right. Companies who buy time will use the centralized system, others will use a dynamic systems. Militaries around the world all use cognitive radio, that is, a dynamic system.

Carey answered Lance’s question about the importance of OGC contribution being spatial contribution: OGC’s contribution is both spatial and temporal. One needs microseconds to sense when the other emitter (the assigned emitter) is ramping up so you can get out. Chris said it will require nanosecond respons. Met authorities have apps where they’re mapping waveforms of lightning strikes and they need to map the waveforms against other wave forms from other receivers. So they use synchronized atomic clocks.

Carey asked Chris for info on how they map the waveforms. Chris replied that they’re monitoring hundreds of strikes per second. That’s why Met got into the temporal. Also when a GPS satellite pops up into view over the horizon, time of that event is dependent on path of radio signal through atmosphere, and angle of refraction depends on atmospheric temperature, so they can use that timing to measure temperature.

Lance asked Carey is there a particular WG within IEEE that might have interest. Carey will email the docs. Is it 5200.21? They’ve been working on dynamic spectrum allocation for years.

Trevor asked re the Mt Aetna example: Is there a need for the emitter installations on either side of the mountain to communicate? Carey: Yes, if there’s a convoy passing, for example. Trevor is looking for connections to other OGC standards. One would need to elaborate the use case to identify which other standards would apply. Agreement, then, that it would be good to identify some use cases. Discussion today serves to help us scope the use cases and literature review. Narrowing the Mt Aetna use case is an action for the future.

Carey: Maybe in the future one use case would be: at a specific many-decimals-precise lat/lon, what frequencies are being used at different times of the day, month and year — That’s something we’ll need with the IoT.

Chris: What about vertical position?

Carey: We need at least one meter

Chris: GPS is not fit for one meter. What about vertical position?

Carey: We need to include it. We have airplanes, and UAVs ….

Chris: The UAV people haven’t yet discovered what aviation learned 50 years. Airplanes use anaeroid barometers. FCC classifies UAVs as being in line of sight. Drones will need to be like airplanes when they fly out of sight, determining their own altitude. CRSs come with quaility aspects and this needs to be part of what’s considered.

So, add the CRS and UAV/UAS WGs to the list of related WGs.

Lucia: In IoT it’s important to be clear that a device is taking control of a frequency: Who is in control of a devices? There should be an ID associated to a signal.

(So add the OGC Security DWG to the list of related WGs.)

Carey: good idea! (quoted radio commentator ) “In the IoT, the worst thing is when you car drives you into a garage and holds you for ransom.”

Actions: minutes, review, list of wgs, list of SDO wgs, later put together a work plan.

Lucia: I will talk to people at ieee re spectrum alloc.

Carey: we need to draw a circle around where were going to work, could go from deep space monitoring to up to the minute warfare.

Lucia suggests to focus on disasters. We have more data in this domain. People will understand and will be able to collaborate. It would sync with OGC initiatives, so the yet-to-be-suggested EM Spectrum SWG could be plugged into OGC testbeds.

Carey agreed re disasters.

Meeting adjourned 11:50 AM CST.

ACTION: Lucia will ask the IEEE people she knows who are interested in our DWG to sign up to the OGC mailing list and wiki and join in the discussions.

ACTION: Carey will send a note on some IEEE groups that might be interested.

ACTION: Lance: Maintain a list of related standards and a list of related OGC WGs.

Introductions

Agenda for the March session of the EM Spectrum DWG

1. Discuss IEEE 1900.6’s new standards project, IEEE P1900.6b.
2. OpenSSRF open source EMF data model.
3. Discussion of possible applications in:
— Cognitive radio
— Mitigating interference with Earth Observation satellite communications
— IoT device identification (and perhaps device security and privacy)
— Orientation of semiconductor devices to indoor and outdoor spatial coordinate reference systems
— Electromagnetic fields' physical effects on molecules, nanoparticles and biological structures
4. Where do we go from here? What are the clearest and most urgent requirements?

---

1. Discussion of IEEE 1900.6

Chuck Heazel downloaded it. 1900.6B is mostly for spectrum database for spectrum assignment negotiation between radios and transmitters. 1900.6A is the original standard and worth looking at. Chuck will take a closer look at it.

2. OpenSSRF open source EMF data model.

Most of the discussion at this working group session focussed on this topic.

At a previous EM Spectrum DWG session, Carey Beall from DISA’s Defense Spectrum Office had informed the group about OpenSSRF.

OpenSSRF data model slides (https://acc.dau.mil/adl/en-US/283273/file/67407/Standard%20Spectrum%20Resource%20Format%20(SSRF)%20v3%20(MCEB%20Pub%208)%20Drawings.pdf) were presented by Lance McKee. He showed the spatial elements and how they are used in multiple places in the data model. There was discussion of the value of representing these spatial elements in GML, both in the abstract model and the XML encoding.

It was noted that there are different EM spectrum data models in use in different application domains, but it’s reasonable to assume that most users of those models would benefit if their standards’ location elements conformed to the OGC geospatial standards platform.

Jaci Knudsen noted that there is an action now in US public law to convert mil standards to public standards wherever possible. In this context, it makes sense to do this in the EM spectrum area. DISA has a mil standard they have coordinated w NATO, and Jaqi has asked the DISA group to start working on this within the EM Spectrum DWG.

Jaci and Chuck confirmed that OpenSSRF’s location elements are basic geospatial primitives. They agreed it would not be hard to insert basic GML primitives as in CML. (.cml is a filename extension for OGC Context documents (http://www.opengeospatial.org/standards/owc).) If the OpenSSRF abstract model is consistent with the location model we’re encoding, DISA can reuse what has been done in OGC, in both the physical and logical level of models, for defense and disaster management and other areas. We may need to add something between the logical and physical models specifying how you go from logical to physical.

Jaci said we would start with XML because it has rigor, then go into something more compact like GeoJSON. We will also need to deal with security. We should do this as soon as possible.

Chuck said this would fit in nicely with GML geometry. We need an ellipse element, too.

Jaci noted, and there was discussion about, the near-certainty that this location model will be implemented in EM spectrum data models used by DoD and NATO. Then, almost surely, it will be picked up in civil/commercial applications.

Joan Masó suggested that we should also use these OGC location elements in EM spectrum models for transponders, many of which use RFID. This would apply in both military and civil emergency and disaster response. It was noted that we haven’t yet dealt with how to blend military support to civil authorities in the US and Europe.

Chuck noted that that’s why we have 1900.6B -- because the US and EU spectrum allocations are different, and other countries like Afghanistan are also different.

ACTION: Chuck: Fit existing OGC (GML) location elements into the OpenSSRF data model.

Lance expressed his pleasure in seeing that there’s now agreement on an area where this DWG can do something significant.

There was little discussion at this session about interference between ground stations and satellites. Some countries are not respecting the assignment of spectrum for such communications. Joan noted that that is one of the activities of GEO, and also ITU.
This is something to discuss in the future in more depth.

Lance noted that interference between sensors, sensors’ wireless communications and other wireless communications will also be a critical issue in IoT. The potential for interference is very great. Lance met with Professor Alex Wyglinski at Worcester Polytechnic Institute. Alex is co-chair of the Community Development Working Group for IEEE 5G and president-elect of the IEEE Vehicular Technology Society. They discussed how this kind of standardization will be important for smart vehicles. That community should be interested in what we’re doing.

Lance recalled a discussion of orientation of small devices. This is another thing that would be worth discussing in the future.

Joan noted that we should remember that some things in domains relevant to our DWG do not depend on spectrum, but global agreements. These issues are probably out of scope for our DWG.

Joan also noted that or mobile location applications, we will need to differentiate between inoor and outdoor requirements and their separate coordinate systems and environments. Much of the mobile industry focus now is on self-driving cars. Intel last week bought an automobile driving company. We can perhaps have a role in standards for vehicular technology.

Lance didn’t find much information about nanotech applications of microwaves. It appears that not much is happening in this domain, but there are indications that there will be more activity in the future.

Lance explained that his personal reasons for starting and participating in this DWG are: 1) coordinating development of an EM spectrum standard for use in bioelectromagnetic science and 2) promoting standards that support environmental monitoring and management of electromagnetic fields.

The standard for use in bioelectromagnetic research would support consistency among studies with respect to comprehensive and complete reporting of EMF exposures. It would also support “multiomics” (or biological and biochemical “big data”) analysis of research data and research documents to accelerate scientific progress in this area.

Joan raised questions about the standard for bioelectromagnetics science, questioning whether OGC was prepared to do this. Lance agreed that this will probably be developed by a team of scientists working outside of the OGC. The open source OpenSSRF data model provides a template that can be pared down. That can be done outside of OGC for the purposes of bioelectromagnetics research.

The standard location elements to be developed in the OGC DWG, once implemented by government and the private sector, would support research as well as environmental monitoring and management of radiation.

Jaci noted that it will be important to develop an MOA between that team of scientists and this OGC DWG so we have an above board collaboration. Lance agreed. We can structure that collaboration to manage expectations on both sides, so that both sides are aware that we’re working together. That will tend to improve the bioelectromagnetics-tailored standard, because it will get wider review and input from domains with potentially different location data requirements. It’s a matter of making a standard be the right tool for the right problem. Below the logical model you get an ecosystem of a lot of standards and there are few people that understand that well. There will be different standards for different applications, but we need consistency to get the data integration and data analytics right.

It was noted that there is a growing global controversy over the existence or non-existence of health effects of weak (sub-thermal) exposures. In some countries there’s much more discussion than in others and in many countries more stringent guidelines and regulations are already being implemented. The OGC position is that bioelectromagnetics research and radiation monitoring are legitimate use cases, but the OGC takes no position on the existence of health risks.

There was brief discussion about the exposures imposed by existing big radars, for both defense and civil applications, as well as from the imminent exponential increase in small radars and related sensors going into vehicles.

Lance and Jaci agreed that if there is indeed trouble coming with respect to ignored EMF health risks, these standards efforts will enable institutions to more immediately and effectively deal with the problem. Stakeholders globally will ultimately benefit from having a good structured relationship between the OGC EM Spectrum standards effort and Lance McKee’s proposed effort to bring OGC location elements into the bioelectromagnetics research community’s data regime.

ACTION: Lance will proceed with his plans to gain support in the bioelectromagnetics research community for assembling a group of scientists who will develop an EM spectrum data model tailored for research. Such a data model would complement data models used for monitoring and managing environmental electromagnetic fields. He will work to establish a liaison between that group and the OGC EM Spectrum DWG.

Lance noted that there is an important outreach component to DWGs. In addition to working with the bioelectromagnetics science community, he would like to focus on outreach for this DWG to bring in stakeholders from other domains such as vehicular technology, IoT, UAVs and wireless device vendors.

So far, however, he has volunteered all the work he has done to get the DWG started and to serve as chair. He now needs to find some paying work, ideally to advance the goals of this DWG. He may resign as chair. He asked for volunteers to be co-chairs who will share responsibility for scheduling and running sessions, arranging presentations, documenting the sessions and maintaining the wiki.

Joan, who is already a co-chair, volunteered to help with this, but he hopes others will assume some of the responsibility. (George Zalidis, Aristotle University of Thessaloniki, i-BEC is also a member of the DWG and a co-chair, but schedule conflicts have prevented participation in most of our DWG sessions.)

ACTION: Lance and Joan: For next WG sessions, attempt to find a new co-chair.

Joan suggested that he and Lance could do some outreach with the IEEE Geoscience and Remote Sensing Society. They publish both scientific journals and a magazine. He thinks the editors would be interested in having an article for the magazine.

ACTION: Lance will work with Joan on a magazine article for IEEE GRSS.

Lance and Joan will also be looking for connections with IEEE. Late last year Lance had email exchanges with people in ITU in Geneva. He let them know about the planned EM Spectrum DWG. There was an opportunity to present at an ITU conference, but expenses were too great. We agreed to keep in touch regarding our respective activities.

ACTION: Joan and Lance will connect with IEEE and ITU to communicate our progress, ask how our work might relate to their work, and suggest harmonization of location elements.

Joan expressed interest in learning more about interference involving communications with drones and interference with drone-mounted RF transponders.

The meeting adjourned at 10:15 AM UTC/GMT +1

Comments:

Carey Beall (USA) -- looking forward to minutes of meeting. We have a disaster system to reduce EMF conflicts ("Mercury") during multi-national disasters -- could provide a frame of reference. We also have developed a NATO-coordinated data exchange standard for frequency assignments and for equipment parametric certification.

Carey Beall (USA) -- the IEEE Std 1900 working group is working on several Dynamic Spectrum Access standards <http://grouper.ieee.org/groups/dyspan/2/>. Examples include, 1900.2, "IEEE Recommended Practice for the Analysis of In-Band and Adjacent Band Interference and Coexistence Between Radio Systems"; 1900.5, "IEEE Standard for Policy Language Requirements and System Architectures for Dynamic Spectrum Access Systems; 1900.6, "IEEE Standard for Spectrum Sensing Interfaces and Data Structures for Dynamic Spectrum Access and other Advanced Radio Communication Systems" -- a full list is at the link provided.
