2Reconfigurable Radios The Problem - ITS
- Reconfigurable Radios are a key technology
solution in several application areas. - From an ITS Reconfigurable Radios perspective
-Wireless standards change on average every 18
months, while average automobile design takes 3
years, and cars last an average of 10 years. - Without Radio Reconfiguration capability,
different RF hardware has to be designed and
provisioned per region, per function - Particularly severe constraint in vehicles
analog and digital audio, GPS tracking,
WWAN/Internet, WWAN/Emergency Information
Delivery, tolls/EZPass, key access, radar, BT,
WLAN, etc. - Updates (critical or not) in any of the wireless
technologies means cost. - Multimode Mobiles need to support different
3G/4G/WLAN/BT standards and 5 frequency bands
today, and more coming - Cost, power implications
- Will get worse with future multipurpose broadband
devices for converged WWAN/WLAN/PAN/BAN..
3Reconfigurable Radios The Problem - Public
Safety
- Reconfigurable Radios are a key technology
solution in several application areas. - In Public Safety applications, Public Safety
Users often have to communicate over a wide range
of spectrum bands, and large geographic areas,
but also need secure, resilient, inter-operable
devices, and coverage in areas whether other
radio devices typically do not work, or have
marginal connectivity. - They also need to be easy to use, durable, long
battery life, and work in high noise
environments, where the User may have other
life-supporting Personal Protective equipment and
Clothing such as Masks, Air Tanks, Helmets,
Gloves, etc., in place. - These are Mission-Critical applications where
safety of life and property is at risk. - Cost and longevity of equipment, along with
reliability and inter-operability are key factors
for this segment which does not have economies of
scale to drive down manufacturing costs.
4Reconfigurable Radios One View of the ITS Goal
- Source Presentation on SDR by Dr John Chapin of
VANU Inc. at the Fully Networked Car Conference,
Geneva, 5-7 March, 2008
5Reconfigurable Radios - Rationale
- Reconfigurable Radios (RRs) are expected to be
upgradable in the field to support future
communications standards and applicable spectral
bands. - RR capable hardware is software loaded, i.e.
customized, for destination at appropriate point
in supply chain. - Some vendors have integrated RRs in deployed
infrastructure and subscriber units already. - Key question Whether labels such as RR, or
Software Defined Radio (SDR) or Cognitive Radio
(CR) are just a technology approach that can be
used to deploy existing Radio Air Interface
standards, or do RR/SDR/CR techniques themselves
need standardization? or BOTH?
6Key Interfaces ITS/SDR Forum
- The ITS industry and the SDR Forum are asking for
a new Digital IF standard - Implies common baseband processor for multiple
radios - Existing specifications - OBSAI, CPRI, DigRF -
found not appropriate for automotive requirements - RF configuration /control is the challenge
- The SDR Forum has significant activity in this
area
Frequency band flexibility is still a major
limitation without Digital RF implementation
7For ITS Applications GSC-13 asked the GSC ITS TF
for a report
- GSC-13 RES 14 Resolved
- 1) to endorse the continuation of the GSC ITS
Task Force hosted by ITU-T APSC TELEMOV and
requests the Task Force to - . . .
- d) recommend the scope for specific standards
needed to enable Software Reconfigurable Radio
(SRR) for automotive applications at the next GSC
meeting and - e) report on progress in each of these areas at
the next GSC meeting - . . .
8What IS a SDR, CR, or RR device?
- This question has been discussed in many fora
over the last few years. - Do we use definitions from ITU, CEPT, EC, FCC,
SDR Forum, or others? - Some argue that SDR technology is application
/implementation specific and that standardization
would stifle technology advancement. - Others advocate that Harmonized Standards already
produced, or to be produced, would need to be
reviewed where regulatory needs have to be
satisfied. - If there is support for SOME standardization what
needs to be standardized? What subject areas are
suitable for standardization? - Some support standardization in Military Systems
but are against standardization of Civil Systems.
9Regulatory Aspects Since GSC-13
- In its 2nd Report and Order and Memorandum
Opinion and Order released November 14, 2008, in
the FCCs White Spaces proceedings, ET Docket
Nos. 04-186 and 02-380, adopting rules for
unlicensed devices to operate in the TV Broadcast
band White Spaces, the FCC advised (para. 8) it
was adopting a plan for fixed devices similar to
the provisions of the draft standard for TV Band
Devices (TVBDs) under consideration by IEEE
802.22. - See IEEE 802.22/D0.2 Draft Standard for Wireless
Regional Area Networks Part 22 Cognitive
Wireless RAN Medium Access Control (MAC) and
Physical Layer (PHY) specifications. - The FCC did note the IEEE 802.22 plan does not
provide for fixed devices to communicate with
personal/portable devices on a master/client
basis. - However, under the FCC Rules adopted in the
Order, fixed TVBDs will be allowed to communicate
with personal/portable devices operating
independently or using a master/client model.
10Regulatory Aspects Since GSC-13
- In that Order the FCC is also concerned with
measurement techniques and ensuring that licensed
services do not receive harmful interference.
Footnote 143 notes - With respect to its indoor measurements, the MSTV
Study showed significant variations in the field
strength of local TV stations in different rooms
and outdoors at ground level at residential
locations within the stations service areas,
while at the same time reception was generally
available on the homes DTV receiving system.

Radio Technology Operating in the TV White Spaces
Completely Protect Licensed TV Broadcasting?
Working Paper 16, (NAF Study) Mark Sturza and
Farzad Ghazvinian, January 2007.
11Regulatory Aspects Since GSC-13
- In its White Space Order, the FCC also provided
for Equipment Certification Under A Proof Of
Performance Standard. - At Para. 257 the FCC notes
- As indicated above, we are providing a special
equipment certification procedure for approval of
sensing only devices that demonstrate the ability
to detect protected services with a high level of
accuracy. In providing this procedure, we
recognize that cognitive radio technology,
including sensing, is in its nascent stage of
development for commercial applications.
Cognitive radio technology holds great promise
for increasing . . . spectrum access to the
benefit of consumers and businesses and we find
it in the public interest to continue to
encourage the development of this technology.

13Recent Activity - ETSI
- As reported at GSC-13 ETSI created a Technical
Committee for Reconfigurable Radio Systems (RRS)
in January 2008 to study the feasibility of
standardization related to Software Defined Radio
(SDR) and Cognitive Radio (CR). - In its current report to GSC-14 ETSI notes
Current Activities include - Feasibility studies of standardization of SDR and
CR - SDR focus on nodes as mobile devices and base
stations, - CR focus on functional architecture
- Liaisons with relevant regulatory bodies.
- Definition issues (SDR, CR) settled aligning
with ITU-R work. - Substantial interest to start to standardize SDR
and CR.
14Recent Activity - ITU
- Definition of SDR
- There is general agreement to use the definition
from Recommendation ITU-R M.1797 as the basis. - Working documents have evolved.
- According to the updated working document towards
draft CPM text of WRC-11 Agenda Item 1.19, the
concepts of SDR and CRS are as follows - Software defined radio (SDR) A radio
transmitter and/or receiver employing a
technology that allows the RF operating
parameters including, but not limited to,
frequency range, modulation type, or output power
to be set or altered by software, excluding
changes to operating parameters which occur
during the normal pre-installed and predetermined
operation of a radio according to a system
specification or standard.
15Recent Activity - ITU
- Cognitive Radio System A radio system employing
technology that allows the system to obtain
knowledge of its operational and geographical
environment, established policies and its
internal state to dynamically and autonomously
adjust its operational parameters and protocols
according to its obtained knowledge in order to
achieve predefined objectives and to learn from
the results obtained. - SOURCE The 6th Meeting of the APT Wireless
Forum, 31 March 03 April 2009, Danang, Vietnam,
Document AWF-6/INP-40
16Recent Activity - ISAAC
- ISACC has proposed to GSC-14 text for a Revision
of the RESOLUTION on this HIS. - ISACC has also included the following in its
input on Rural and Remote Broadband Services
(RRBS), RESOLUTION GSC-14/21 - Considering . . . . c) that many countries
consider broadband delivery or Internet delivery
as part of their infrastructure (A number of
countries are investing in rural broadband as
part of their economic stimulus programs). - Resolves . . . 7) to encourage the inclusion of
smart radio technology in broadband services
intended to operate in remote and rural areas to
allow access to underutilized radio spectrum.
17Recent Activity - TIA
- Relative to Reconfigurable Radios, TIA TR-8
focuses on Public Safety - Users in TR-8 have expressed a desire to look at
SDR aspects, and a subcommittee was created years
ago, TR-8.7, but has been relatively inactive. - The P25 Steering Committee continues to get
reports on the SDR Forum, and continues to have
interest. - Multiple bands are in use by systems for first
responders - TR-8 Chair reported renewed interest in Software
Defined Radio (SDR) work. - TIA TR-8 P25 Air Interface Standards have been
deployed using SDR/CR/RRS-like technologies by at
least three vendors since GSC-13.
18Challenges
- Digital IF interface specification (ITS)
- Support for multiple radios, on plug and play
basis, nearer term - Support for growing number of wireless standards
- C2K, GSM/GPRS/EDGE, EV-DOrA, HSPA, LTE, WiMAX,
802.11x, 802.15.x, 802.16d, 802.20, etc as
applicable) - Also BT2.x/3.x, Zigbee, UWB, NFC, new CAI for BAN
profiles, etc. - Tunable filters and amplifiers, broadband
antennas. - Digital RF for global frequency flexibility, (no
need for agility?) - 450MHz/700MHz/850MHz/900MHz/GPS1.575GHz/Galileo1.2
78GHz/GLONASS/1.7GHz/1.8GHz/1.9GHz/AWS/2.3GHz/2.5G
Hz/3.3GHz/3.5GHz/4.9GHz/5.8GHz - low power, low footprint, in CMOS, hence low
cost, RFICs - an implementation challenge, to achieve economies
of scale. - FCC security requirement to prevent hacking to
alter operating band.

27IEEE Definitions of Dynamic Spectrum Access and
Cognitive Radio
- According to the P1900.1 Standard -
- Dynamic Spectrum Access is the real-time
adjustment of Spectrum Utilization in response to
changing circumstances and objectives. - Cognitive Radio is a type of Radio in which
communication systems are aware of their
environment and internal state and can make
decisions about their radio operating behavior
based on that information and predefined
objectives.
