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..

Reconfigurable Radios – The Problem - ITS


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.

Reconfigurable Radios – One View of the ITS Goal


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?

Reconfigurable Radios - Rationale


Key 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 radiosExisting specifications - OBSAI, CPRI, DigRF - found not appropriate for automotive requirements

RF configuration /control is the challengeThe SDR Forum has significant activity in this area

Frequency band flexibility is still a major limitation

without Digital RF implementation


For 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; ande) report on progress in each of these areas at the next GSC meeting; . . .


What “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.


Regulatory Aspects Since GSC-13

In its “2nd Report and Order and Memorandum Opinion and Order” released November 14, 2008, in the FCC’s 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.



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. See also Attachment to NAF Technical comments, “White Spaces Engineering Study: Can Cognitive 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.



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.

Recent 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.


Recent Activity - ITU

Definition of SDRThere 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.


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.

Recent 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.”


Recent 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.
