Potential Opportunity for Energy Harvesting
Sensor and RFID
Applications?
  • On May 14, 2008 at the IEEE 802.15 Interim
    meetings in Jacksonville, FL Jeff Solum with
    Starkey Laboratories made two presentations
    regarding a request for waiver of FCC Part 15.247
    rules for a reduction of minimum channel
    bandwidth from 500 Khz to potentially 100 Khz.

The Question
IEEE 802.15.4 PHY Specifications
Increase channels available from 10 to ?
Can we maintain Data Bit Rate and reduce PHY
energy use by creating a PHY that takes advantage
of a potential FCC Part 15.247 waiver request for
lt500 Khz bandwidth channels?
Increase channels available from 16 to ?

Potential Starkey Laboratories FCC Waiver Request
  • Starkey Laboratories is interested in operating
    said low power devices within the confines of
    Section 15.247(a)(2), but with a lower minimum
    bandwidth than currently allowed by rule. Section
    15.247(a)(2) currently states in part that the
    minimum 6 dB bandwidth shall be at least 500
    kHz. Starkey Laboratories is requesting that the
    aforesaid language be waived and that it be
    allowed to operate said low power devices with a
    lower minimum 6 dB bandwidth of at least 100
    kHz.
  • The proposed waiver would allow Starkey to
    operate said low power devices with a lower
    minimum 6 dB bandwidth of 100 kHz, while
    maintaining the 8 dBm/3 kHz power spectral
    density specified in Section 15.247(e). Table 1
    shows an example of the total radiated power that
    would be allowed if the waiver were granted.

802.11b/g and 802.15.4 Spectrum Sharing
With a smaller channel bandwidth PHY, 802.15.4
could provide more non-interferring 802.15.4
channels between and above 802.11b/g channels 1,
6, and 11. Only 802.15.4 channels 15, 20, 25, and
26 fall outside 802.11b/g channels 1, 6, and 11
at this time.

Overview and Background on EPCglobal RFID /
Sensor Specifications and the IEEE P1451 Sensor
Standards

RFID Standards Organizations
  • Two organizations are most involved in drafting
    standards for RFID technology
  • ISO
  • No Active RFID or Sensor Tag Standard in the 915
    MHz and 2.4 GHz bands
  • EPCglobal
  • No Active RFID or Sensor Tag Specification in the
    915 MHz and 2.4 GHz bands

ISO/IEC 18000-42004
  • Information technology -- Radio frequency
    identification for item management -- Part 4
    Parameters for air interface communications at
    2,45 GHz
  • http//www.iso.org/iso/iso_catalogue/catalogue_tc/
    catalogue_detail.htm?csnumber34115
  • Abstract
  • ISO/IEC 18000-42004 defines the air
    interface for radio-frequency identification
    (RFID) devices operating in the 2,45 GHz
    Industrial, Scientific, and Medical (ISM) band
    used in item management applications. Its purpose
    is to provide a common technical specification
    for RFID devices that may be used by ISO
    committees developing RFID application standards.
  • ISO/IEC 18000-42004 is intended to allow
    for compatibility and to encourage
    inter-operability of products for the growing
    RFID market in the international marketplace.
    ISO/IEC 18000-42004 defines the forward and
    return link parameters for technical attributes
    including, but not limited to, operating
    frequency, operating channel accuracy, occupied
    channel bandwidth, maximum EIRP, spurious
    emissions, modulation, duty cycle, data coding,
    bit rate, bit rate accuracy, bit transmission
    order, and where appropriate operating channels,
    frequency hop rate, hop sequence, spreading
    sequence, and chip rate. It further defines the
    communications protocol used in the air
    interface.
  • ISO/IEC 18000-42004 contains two modes.
    The first is a passive tag operating as an
    interrogator talks first while the second is a
    battery assisted tag operating as a tag talks
    first. The detailed technical differences between
    the modes are shown in the parameter tables.
  • MODE1 PASSIVE BACKSCATTER RFID SYSTEM
  • The FHSS backscatter option or the narrow
    band operation RFID system shall include an
    interrogator that runs the FHSS backscatter
    option 1 RFID protocol or in narrow band
    operation, as well as one or more tags within the
    interrogation zone
  • MODE 2 LONG RANGE HIGH DATA-RATE RFID SYSTEM
  • This clause describes a RFID system,
    offering a gross data rate up to 384 kbps at the
    air interface in case of Read/Write (R/W) tag. In
    case of Read Only (R/O) tag the data rate is 76.8
    kbps. The tag is battery assisted but back
    scattering. By using of battery powered tags such
    a system is well designed for long-range RFID
    applications.

ISO/IEC 18000-62004
  • Information technology -- Radio frequency
    identification for item management -- Part 6
    Parameters for air interface communications at
    860 MHz to 960 MHz
  • http//www.iso.org/iso/iso_catalogue/catalogue_tc/
    catalogue_detail.htm?csnumber34117
  • Abstract
  • ISO/IEC 18000-62004 defines the air
    interface for radio-frequency identification
    (RFID) devices operating in the 860 MHz to 960
    MHz Industrial, Scientific, and Medical (ISM)
    band used in item management applications. Its
    purpose is to provide a common technical
    specification for RFID devices that may be used
    by ISO committees developing RFID application
    standards. ISO/IEC 18000-62004 is intended to
    allow for compatibility and to encourage
    inter-operability of products for the growing

    bit rate, bit rate accuracy, bit transmission
    order, and where appropriate operating channels,
    frequency hop rate, hop sequence, spreading
    sequence, and chip rate. It further defines the
    communications protocol used in the air
    interface.
  • ISO/IEC 18000-62004 contains one mode
    with two types. Both types use a common return
    link and are reader talks first. Type A uses
    Pulse Interval Encoding (PIE) in the forward
    link, and an adaptive ALOHA collision arbitration
    algorithm. Type B uses Manchester in the forward
    link and an adaptive binary tree collision
    arbitration algorithm. The detailed technical
    differences between the two types are shown in
    the parameter tables.

EPC Class Descriptions
  • Class 0/1 tags both represent basic capability.
    They are read only passive identity tags. The
    passive tags derive the power needed for
    operation from the readers RF signal. They
    communicate back with the reader using
    backscatter modulation. The Class 0 protocol uses
    out-of-band signaling while Class 1 protocol uses
    in-band signaling. Class 0 tags are read-only,
    programmed by the manufacturer, whereas Class 1
    tags are generally viewed as write once and read
    many where the writing can be done either by the
    manufacturer or by the user.
  • Class 2 tags are passive tags with additional
    functionality like encryption or memory.
  • Class 3 tags are semi-passive tags. These tags
    have a battery source for operating the internal
    circuitry, whereas they do not have a transmitter
    for sending back the information.
  • All the tags from Class 0 to Class 3 use
    backscatter techniques to communicate to the
    reader at UHF frequencies.
  • Class 4 tags are active tags, which have a Class
    4 tags are active tags, which have a battery
    source and a transmitter. They may be capable of
    broadband peer-to-peer communication with other
    active tags in the same frequency band or other
    readers.
  • Class 5 tags are devices that can power other
    tags as well as communicate with other Class 4
    tags. An example is a RFID reader that is capable
    of powering up the other Class 0/1 tags.

IEEE P1451 Overview
  • IEEE 1451 is a family of Smart Transducer
    Interface Standards that describe a set of open,
    common, network-independent communication
    interfaces for connecting transducers (sensors or
    actuators) to microprocessors, instrumentation
    systems, and control/field networks.
  • The key feature of these standards is the
    definition of a TEDS (Transducer Electronic Data
    Sheet). The TEDS is a memory device attached to
    the transducer, which stores transducer
    identification, calibration, correction data, and
    manufacture-related information.
  • The goal of 1451 is to allow the access of
    transducer data through a common set of
    interfaces whether the transducers are connected
    to systems or networks via a wired or wireless
    means.
  • The family of IEEE 1451 standards are sponsored
    by the IEEE Instrumentation and Measurement
    Societys Sensor Technology Technical Committee.
