The first part of the tutorial provides an overview of the recently completed standard IEEE std. 802.22-2011. The second part of the tutorial is to educate the IEEE 802 community as to why a new P802.22b amendment to the IEEE std. 802.22-2011 is needed and what it will do.

3 doc.: IEEE 802.22-11/0132r03 Submission November 2011 Problem: Digital Divide Exists Today According to the recent TIME Magazine article (October 31 st issue), 73% of the world population (5.1 Billion people) does not have access to internet 49.5% of the people (3.465 Billion) in the world live in rural areas. It is expensive to lay fiber / cable in rural and remote areas with low population density. Wireless is the only solution. Backhaul / backbone internet access for rural areas is very expensive (50% of the cost) Traditional wireless carriers have focused on urban areas with high populations density (faster Return on Investment) using licensed spectrum Example - America: About 28 percent of rural America, lack access to Internet with speeds of three megabits per second or faster, compared with only 3 percent, in non-rural areas, according to an FCC report titled "Bringing Broadband to Rural America” Example - India: In India, a country with more than 1.2 Billion people, more than 500 Million people have cell phones but less than 0.75% of the population has access to high speed internet access This has created a DIGITAL DIVIDE Slide 3

Excess spectrum is called the digital dividend and it can be used to provide broadband access while ensuring that no interference is caused to primary users. In some administrations like the United States, opportunistic license-exempt usage of the spectrum used by the incumbents is allowed on a non-interfering basis using cognitive radio techniques.

The standard supports aggregate data rates greater than the maximum data rate supported by the IEEE std. 802.22-2011. This standard defines new classes of 802.22 devices to address these applications and supports more than 512 devices. This standard also specifies techniques to enhance communications among the devices and makes necessary amendments to the cognitive, security & parameters and connection management clauses. Slide 65

66 doc.: IEEE 802.22-11/0132r03 Submission November 2011 PAR for P802.22b continued 5.3 Is the completion of this standard dependent upon the completion of another standard: No 5.4 Purpose: This document will not have a purpose clause. 5.5 Need for the Project: There are various broadband services and monitoring applications in the context of wireless regional area networks where communications can be better served by introducing new classes of 802.22 devices with capabilities appropriate for such applications. In addition, extending regional area broadband services to applications such as real-time and/or near real-time monitoring, emergency broadband services, remote medical services etc, requires higher data rates and greater number of devices. Enhanced technologies become necessary to enable communications among devices to support those applications. None of the features mentioned above can be supported by the IEEE std. 802.22-2011 and hence, a new project is required for amendment. 5.6 Stakeholders for the Standard: The stakeholders include: Manufacturers and users of IEEE Std. 802.22-2011 devices and other operating entities to which the standard may need to interface.

Slide 67

68 doc.: IEEE 802.22-11/0132r03 Submission November 2011 5 Criteria for P802.22b 1.Broad Market Potential a) Broad sets of applicability The proposed amendment will enable a number of new broadband applications in television white spaces (TVWS) in the context of wireless regional area networks by combining broadband services and monitoring applications. b) Multiple vendors and numerous users It is expected that this amendment will be applicable in all markets where the 802.22 technology will be used. The new features of the amendment are expected to bring new equipment vendors. c) Balanced costs (LAN versus attached stations) It is expected that the new features of the amendment can be implemented with reasonable cost resulting in overall better value for money. Slide 68

69 doc.: IEEE 802.22-11/0132r03 Submission November 2011 5 Criteria for P802.22b (Continued) 2. Compatibility The amendment will be compatible with IEEE 802 family of standards, specifically 802 overview and architecture, 802.1 including 802.1D and 802.1Q. Slide 69

70 doc.: IEEE 802.22-11/0132r03 Submission November 2011 5 Criteria for P802.22b (Continued) 3. Distinct Identity a) Substantially different from other IEEE 802 standards There is no other IEEE 802 standard or project, for combined broadband services and monitoring applications aimed at wireless regional area networks using television white space bands. b) One unique solution per problem (not two solutions to a problem) Combined broadband services and monitoring applications for wireless regional area networks by using television white space bands are not currently considered by any other wireless standard or project. Hence, this is the only solution to this problem. c) Easy for the document reader to select the relevant specification Yes, since the proposed standard will produce an amendment to the IEEE std. 802.22-2011. Slide 70

71 doc.: IEEE 802.22-11/0132r03 Submission November 2011 5 Criteria for P802.22b (Continued) 4. Technical Feasibility a) Demonstrated system feasibility There are a number of examples of successful prototype operation in TVWS by complying with requirements of various regulatory organizations (e.g., Federal Communications Commission (FCC), USA, Infocomm Development Authority (IDA), Singapore, etc.). b) Proven technology, reasonable testing Experimental licenses have been issued for operation in TVWS in many countries (e.g. Federal Communications Commission (FCC), USA, Infocomm Development Authority (IDA), Singapore etc). Communications over TVWS are being tested by regulatory organizations in those countries. c) Confidence in reliability Results of TVWS test trial campaigns being carried out by various regulatory organizations provide confidence in the reliability of the proposed project. d) Coexistence of 802 wireless standards specifying devices for unlicensed operation This amendment supports mechanisms to enable coexistence with other 802 systems in the same band. A coexistence assurance document will be produced by the WG as a part of the WG balloting process. Slide 71

72 doc.: IEEE 802.22-11/0132r03 Submission November 2011 5 Criteria for P802.22b (Continued) 5. Economic Feasibility a) Known cost factors, reliable data The amendment uses technologies that are well-proven in the market in a cost effective manner. b) Reasonable cost for performance The IEEE 802.22 systems are designed for operation in rural areas where the population density is likely to be low. However, an IEEE 802.22 base station (BS) covers a large area typically with 30 km radius implying a reasonable cost per geographical unit of coverage. The CPEs are expected to be inexpensive and hence cost for overall network performance would be reasonable. c) Consideration of installation costs This amendment will be later combined to the base 802.22 standard resulting in an updated version of IEEE std. 802.22-2011. Installation costs will be those of the updated base standard and are expected to be reasonable. Slide 72

73 doc.: IEEE 802.22-11/0132r03 Submission November 2011 Slide 73 Conclusions IEEE 802.22 standard is optimized for VHF/UHF TV channels to provide broadband services There is no other IEEE 802 standard or project, for combined broadband services and monitoring applications aimed at wireless regional area networks using television white space bands. There is no other IEEE 802 Standard that is specifically designed for rural remote area broadband access. There are various broadband services and monitoring applications in the context of wireless regional area networks where communications can be better served by introducing new classes of 802.22 devices with capabilities appropriate for such applications. In addition, extending regional area broadband services to applications such as real- time and/or near real-time monitoring, emergency broadband services, remote medical services etc, requires higher data rates and greater number of devices. Enhanced technologies become necessary to enable communications among devices to support those applications. None of the features mentioned above can be supported by the IEEE std. 802.22-2011 Hence, a new P802.22b Amendment project is required.
