<month year>

<November 2011>
PTC-IG Goals and Intentions
This standard may be a new IEEE standard or an amendment to IEEE It’s intention is to standardize the over-the-air radio link for the mandated US Positive Train Control law established in 2008:
Enables operation in a variety of radio frequency bands including the US-licensed MHz spectrum
Supports typical data rates from 9.6 to 200 kbits per second
Support for multiple simultaneous networks
Provides for mobility up to 1000km/h (closing speeds, train to train)
Supports radio ranges up to 70km
Shall operate in not-necessarily contiguous channel sizes as small as 5kHz but generally up to 50kHz
Requires flexible and robust QoS with attention to connection time, transfer delay, registration delay, and handover time
Allows for rapidly changing (several per second) network membership
Realizes optimal and power efficient device command and control applications for energy-scavenged end devices

4. Goals and Intentions 2 Propagation path loss of at least 140 dB
<November 2011>
Goals and Intentions 2
Propagation path loss of at least 140 dB
Potential for dozens of simultaneous wayside and network connections per locomotive
Asymmetric application data flow
Extreme difference in capabilities and performance between wayside, network access points, and locomotives
Locomotive and Network Access Points may support all standardized modulations (MCS) and data rates
May be requirements to support antenna diversity or antenna beam steering
Wayside equipment may be required to conserve energy
Reliable operation in dramatically changing environments (no control over environment)
This amendment also provides mechanisms that enable coexistence with other systems in the same band(s) including IEEE , , and systems, assuming those networks exist in set of bands
Because of its nature, the standard developed here may be broadly applicable to other monitoring and control Intelligent Transportation System (ITS) functions.

6. Instructions for the WG Chair
<month year>
doc.: IEEE < e>
<November 2011>
The IEEE-SA strongly recommends that at each WG meeting the chair or a designee:
Show slides #1 through #4 of this presentation
Advise the WG attendees that:
The IEEE’s patent policy is consistent with the ANSI patent policy and is described in Clause 6 of the IEEE-SA Standards Board Bylaws;
Early identification of patent claims which may be essential for the use of standards under development is strongly encouraged;
There may be Essential Patent Claims of which the IEEE is not aware. Additionally, neither the IEEE, the WG, nor the WG chair can ensure the accuracy or completeness of any assurance or whether any such assurance is, in fact, of a Patent Claim that is essential for the use of the standard under development.
Instruct the WG Secretary to record in the minutes of the relevant WG meeting:
That the foregoing information was provided and that slides 1 through 4 (and this slide 0, if applicable) were shown;
That the chair or designee provided an opportunity for participants to identify patent claim(s)/patent application claim(s) and/or the holder of patent claim(s)/patent application claim(s) of which the participant is personally aware and that may be essential for the use of that standard
Any responses that were given, specifically the patent claim(s)/patent application claim(s) and/or the holder of the patent claim(s)/patent application claim(s) that were identified (if any) and by whom.
The WG Chair shall ensure that a request is made to any identified holders of potential essential patent claim(s) to complete and submit a Letter of Assurance.
It is recommended that the WG chair review the guidance in IEEE-SA Standards Board Operations Manual and in FAQs 12 and 12a on inclusion of potential Essential Patent Claims by incorporation or by reference.
Note: WG includes Working Groups, Task Groups, and other standards-developing committees with a PAR approved by the IEEE-SA Standards Board.

7. Participants, Patents, and Duty to Inform
<month year>

<November 2011>
Participants, Patents, and Duty to Inform
All participants in this meeting have certain obligations under the IEEE-SA Patent Policy. Participants:
“Shall inform the IEEE (or cause the IEEE to be informed)” of the identity of each “holder of any potential Essential Patent Claims of which they are personally aware” if the claims are owned or controlled by the participant or the entity the participant is from, employed by, or otherwise represents
“Personal awareness” means that the participant “is personally aware that the holder may have a potential Essential Patent Claim,” even if the participant is not personally aware of the specific patents or patent claims
“Should inform the IEEE (or cause the IEEE to be informed)” of the identity of “any other holders of such potential Essential Patent Claims” (that is, third parties that are not affiliated with the participant, with the participant’s employer, or with anyone else that the participant is from or otherwise represents)
The above does not apply if the patent claim is already the subject of an Accepted Letter of Assurance that applies to the proposed standard(s) under consideration by this group
Quoted text excerpted from IEEE-SA Standards Board Bylaws subclause 6.2
Early identification of holders of potential Essential Patent Claims is strongly encouraged
No duty to perform a patent search

8. Patent Related Links
<November 2011>
All participants should be familiar with their obligations under the IEEE-SA Policies & Procedures for standards development.
Patent Policy is stated in these sources:
IEEE-SA Standards Boards Bylaws
IEEE-SA Standards Board Operations Manual
Material about the patent policy is available at
If you have questions, contact the IEEE-SA Standards Board Patent Committee Administrator at or visit

9. Call for Potentially Essential Patents
<November 2011>
If anyone in this meeting is personally aware of the holder of any patent claims that are potentially essential to implementation of the proposed standard(s) under consideration by this group and that are not already the subject of an Accepted Letter of Assurance:
Either speak up now or
Provide the chair of this group with the identity of the holder(s) of any and all such claims as soon as possible or
Cause an LOA to be submitted

10. Other Guidelines for IEEE WG Meetings
<month year>
doc.: IEEE < e>
<November 2011>
Other Guidelines for IEEE WG Meetings
All IEEE-SA standards meetings shall be conducted in compliance with all applicable laws, including antitrust and competition laws.
Don’t discuss the interpretation, validity, or essentiality of patents/patent claims.
Don’t discuss specific license rates, terms, or conditions.
Relative costs, including licensing costs of essential patent claims, of different technical approaches may be discussed in standards development meetings.
Technical considerations remain primary focus
Don’t discuss or engage in the fixing of product prices, allocation of customers, or division of sales markets.
Don’t discuss the status or substance of ongoing or threatened litigation.
Don’t be silent if inappropriate topics are discussed … do formally object.
See IEEE-SA Standards Board Operations Manual, clause and “Promoting Competition and Innovation: What You Need to Know about the IEEE Standards Association's Antitrust and Competition Policy” for more details.

Chair’s Role
“…the chairperson of the working group is key to what and how fast a standard is produced.”
The chair of the committee acts as a facilitator with little power to legislate. The chair must be knowledgeable about the subject but also know how a standard may be used by various segments of the industry. A chairperson should be a leader-diplomat-observer, in equal proportions. Also, the chairperson should not be a doer, perfectionist or obstructionist. This is consistent with the view of the chairperson as a skilled leader with strong negotiation skills who delegates.

14. Schedules vs Reality Standards take time, some more, some less
<November 2011>
Schedules vs Reality
Standards take time, some more, some less
US PTC implementation mandate end of 2015 is very soon
Modern radio transceivers are generally firmware- or software-based, so in-field upgrades can be practical
For manufacturers working on next-generation PTC radios today, flexibility in design now can allow straightforward upgradability in the future
Cases in point
GSM Cellular Base Stations: EDGE (“2.75G”) was a firmware upgrade to GPRS (“2.5G”) for many base stations
Wi-Fi n: Draft release was in place for several years and millions of devices sold into the marketplace; when standard was ultimately released, many of those devices could be upgraded via firmware update
IEEE : New frequency bands added could be accommodated by wireless transceivers already deployed, sometimes through software modification
