10. doc.: 15-11-0857-01-PTCsg Submission PTC-SG Goals and Intentions This standard may be a new IEEE 802.15 standard or an amendment to IEEE 802.15.4. The 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 216-222MHz spectrum Supports typical data rates from 9.6 to 200 kbits per second Support for multiple simultaneous networks Provides for mobility up to 500km/h (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 November 2011 Jon Adams, Lilee SystemsSlide 10

11. doc.: 15-11-0857-01-PTCsg Submission Goals and Intentions 2 Propagation path loss of approximately 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 802.11, 802.15, and 802.16 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.

12. doc.: 15-11-0857-01-PTCsg Submission PAR (Project Authorization Request) 1 The important bits: 5.2 Scope: This amendment specifies a physical layer for 802.15.nn US Positive Train Control regulatory requirements and also any necessary MAC changes needed to support this physical layer. The standard: enables operation in a variety of radio frequency bands including the US-licensed 216-222MHz spectrum, supporting typical data rates from 9.6 to 200 kbits per second; provides for mobility up to 1000km/h (closing speeds, train to train); supports radio ranges up to 50km; shall operate in not-necessarily continguous channel sizes as small as 5kHz; requires flexible and robust QoS with attention to connection time, transfer delay, registration delay, and handover time; allows for rapidly changing network membership which may or may not require association; realizes optimal and power efficient device command and control applications for energy-scavenged end devices. Because of its nature, the standard developed here may be broadly applicable to other monitoring and control Intelligent Transportation System (ITS) functions.
