CRTC issued Telecom Policy Decision 2009-40 regarding the implementation of Wireless Phase II E9-1-1 Service in Canada. Within this Decision, the Emergency Services (9-1-1) Working Group (ESWG) received the following direction of Wireless Phase II E9-1-1 Stage 2 feature development: 22. The Commission considers that wireless Phase II Stage 2 E9-1-1 features would provide further significant benefits to PSAPs and consumers, and should be implemented as soon as technological solutions are available. To this end, the Commission requests that the ESWG file a report within six months of the date of this decision on its findings regarding the deployment of wireless Phase II Stage 2 E9-1-1 features. Upon review of this report, the Commission will specify the Stage 2 implementation requirements and time frames. As described in ESRE0046 Technical and Operational Requirements of Wireless Phase II E9-1-1 Implementation, the ESWG recommended and the Commission approved that the current Phase I E9-1-1 capability must be preserved and should form a basis for all wireless Phase II E9-1-1 calls. Phase I E9-1-1 service provides the subscribers telephone number, Wireless Service Provider (WSP), cell sector and the address of the cellular tower which routed the call to the PSAP. Phase II Stage 1 is described as the “provision of X, Y [latitude, longitude] coordinate information and location system parameters that PSAPs [Public Safety Answering Points] use to determine a callers location.” Phase II Stage 1 has been described in ESRE0046. Phase II Stage 2 is described as the “provision of mid-call location updates, plus provision of wireless Phase II E9-1-1 service for roamers and unsubscribed handsets, to be deployed as technology solutions become available.” This report (ESRE0049) does not include mid-call location updates, which has been addressed in ESRE0050. 2 Introduction The purpose of this document is to identify the technological challenges and proposed solutions for the provisioning of wireless E9-1-1 Phase II Stage 2 features, with the exception of In-Call Location Update (ICLU), which is analyzed in TIF 59 and documented in report ESCO0050. The report herein was developed through the combined

  • Migration to 3G Technology Standards: Europe, Japan, South Korea, and the U.S. by Richard Nunno, International Bureau, FCC
    Migration to 3G Technology Standards: Europe, Japan, South Korea, and the U.S. By Richard Nunno, International Bureau, FCC Revised July 21, 2003 For over a decade, the International Telecommunication Union (ITU) has been supporting the international effort to develop an advanced third-generation (3G) mobile telecommunications service that has a higher bandwidth than previous and existing mobile services and that subscribers can seamlessly use across international borders (known as global roaming). To that end, the ITU has identified spectrum and developed technical standards for International Mobile Telecommunications 2000 (IMT-2000), the official name for 3G services. The ITU’s World Administrative Radiocommunication Conference (WARC) in 1992 and World Radiocommunication Conference (WRC) in 2000 identified several bands of spectrum that could be used for 3G services. The mobile telecommunications industry has started delivering 3G services that provide broadband applications including voice, data, and video. As defined by the ITU, 3G signal transmission rates must be able to reach 2 megabits per second (Mbps) or higher for indoor (low mobility) wireless applications (more than 35 times faster than today’s 56 kilobits per second (kbps) dial-up PC modems). 3G rates may be slower (384 kbps) for pedestrian traffic, and 144 kbps for high mobility (vehicular) traffic.1 How each country is implementing 3G systems depends on a number of factors, such as the country’s 3G spectrum allocations, the standards it adopts for 3G (if it adopts any standards vs. letting the marketplace make the decision), and the country’s current mobile telephony system configuration. Because a great deal of information and analysis is already available on the spectrum-related issues surrounding 3G implementation, this report focuses only on the technology standards issues pertaining to 3G.

  • The Spectrum Policy Dictionary
    The GSMA spectrum primer series The spectrum policy dictionary 1 2 The spectrum policy dictionary These handbooks provide a general introduction to mobile spectrum, how it is managed and the challenge posed by rapidly growing data usage. They have been designed for readers who don’t have a technical background in the subject. While this is only a very brief introduction to the subject, these handbooks should hopefully provide a useful overview. 4 The titles in this series are: Introducing radio spectrum Introducing spectrum management Managing spectrum for growing data The spectrum policy dictionary 5 1G The first generation of ‘cellular’ mobile phone systems used in the late 1970s until the early 1990s. These analogue-based systems were replaced by 2G digital mobile systems - most notably GSM. Examples include AMPS (Advanced Mobile Phone System), NMTS (Nordic Telecommunication System) and TACS (Total Access Communications). 2G The second generation of ‘cellular’ mobile phone systems which appeared in the 1990s were the first to employ digital coding. The vast majority of 2G mobile networks around the world use GSM technology. However, there are other 2G systems including D-AMPs, PDC, iDEN and most notably cdmaOne which continues to be used by some operators around the world. 2.5G see GPRS 2.75G see EDGE 3G The third generation of ‘cellular’ mobile phone systems were the first to be designed from the outset to support high speed data services as well as voice. The most dominant system used is WCDMA which was deployed by the operators which previously used GSM. However, other systems are used including CDMA2000 (largely by operators that previously used cdmaOne) and the Chinese system TD-SCDMA.

  • Performance Characteristics of an Operational Wimax Network James Martin, Member, IEEE, and James Westall, Affiliate, IEEE CS
    1 Performance Characteristics of an Operational WiMAX Network James Martin, Member, IEEE, and James Westall, Affiliate, IEEE CS Abstract—The term WiMAX is used to refer to a collection of standards, products, and service offerings derived from the IEEE 802.16 family of standards for metropolitan area wireless networks. A significant body of published research in the WiMAX domain exists, but the focus of much of it is on the use of analytic or simulation models to evaluate aspects of physical layer protocols, medium access control protocols, or proposed scheduling algorithms. It this paper we describe performance characteristics of an operational WiMAX testbed upon which we were able to conduct controlled experiments in the absence of competing traffic. We characterize latency, throughput, protocol overhead, packet loss, and the impact of WiMAX on TCP dynamics. Index Terms—WiMAX, IEEE 802.16, wireless, performance. ! 1 INTRODUCTION Where commercial offerings do exist, the service The term WiMAX, an acronym for Worldwide Interop- providers are generally unwilling to release usage and erability for Microwave Access, is commonly used to performance data.
