Current Legislation ActivitiesCurrent Legislation Activities
• Senator Ted Stevens (R-Alaska) introduced S. 2332, the American Broadband for Communities Act. The legislation would make unused spectrum in the 72-698 MHz band currently allocated to television broadcasters available for use by unlicensed wireless devices. The bill would require equipment using the spectrum to identify whether or not particular spectrum is in use, and only use spectrum not being used by broadcasters. The proposal would direct the FCC to set technical guidelines for equipment and create an interference complaint resolution program for broadcasters.
• In addition, Senators George Allen (R-Virginia) and John Kerry (D-Massachusetts) recently introduced S. 2327, the Wireless Innovation Act. The legislation is similar to S.2322 and makes unused spectrum in the 72-698 MHz band currently allocated to television broadcasters available for use by unlicensed wireless devices.
• Bills are currently stalled in committee but may see action in the 2007 session
Tech CEOs urge U.S. find more wireless airwaves
Tech CEOs urge U.S. find more wireless airwaves
• WASHINGTON (Reuters) - Chief executive officers of some leading technology companies plan to call on Thursday for the U.S. government to find more wireless airwaves for use as new applications emerge. The Technology CEO Council said on Wednesday it will issue a report urging Congress to order the Bush Administration to analyze which airwaves are not being used best, and how they might be re-allocated. Additionally, the organization plans to urge the Federal Communications Commission and the National Telecommunications and Information Administration to consider allowing government airwaves that are underutilized to be used for other purposes. "Our nation's wireless needs are too often governed by 1970s regulations that hinder economic progress and innovation," Motorola Inc. CEO Edward Zander said in a statement obtained by Reuters. He serves as chairman of the technology organization. The group pushing for the changes also includes executives from Hewlett-Packard Co. IBM, Intel Corp., Dell Inc., EMC Corp. and Unisys Corp., among others.
• Wireless companies have been hungry for more airwaves as they deploy new services like high-speed Internet and video content. The executives also plan to suggest the FCC ease restrictions on wireless licenses so companies have more flexibility to use the airwaves for new services. They also will recommend making more unlicensed spectrum available that could be used for a variety of purposes. The organization also plans to recommend Congress and regulators ensure that public safety organizations have the airwaves they need. Safety officials have complained about poor communications during disasters like the September 11 attacks and Hurricane Katrina. The FCC is slated to start auctioning some airwaves June 29, including some airwaves that government agencies are vacating. Other airwaves are expected to be sold in 2008 ahead of the 2009 move by U.S. television broadcasters from analog wireless airwaves to other airwaves for their digital television signals.

WiMAX ApplicationsWiMAX Applications
• There are two main applications of WiMAX today: fixed WiMAX applications are point-to-multipoint enabling broadband access to homes and businesses, whereas mobile WiMAX offers the full mobility of cellular networks at true broadband speeds. Both fixed and mobile applications of WiMAX are engineered to help deliver ubiquitous, high-throughput broadband wireless services at a low cost.
• Mobile WiMAX is based on OFDMA (Orthogonal Frequency Division
Multiple Access) technology which has inherent advantages in throughput, latency, spectral efficiency, and advanced antennae support; ultimately enabling it to provide higher performance than today's wide area wireless technologies. Furthermore, many next generation 4G wireless technologies may evolve towards OFDMA and all IP-based networks as an ideal for delivering cost-effective wireless data services.
Intel’s Plans for WiMAXIntel’s Plans for WiMAX
• Mobile WiMAX: Intel® WiMAX Connection 2250 Intel® WiMAX Connection 2250 is a low-cost system-on-chip that supports IEEE 802.16-2004 and IEEE 802.16e-2005, enabling WiMAX modems for use with fixed or mobile networks. Intel® WiMAX Connection 2250 is optimized for cost effective WiMAX modems and benefits from the economics of combined IEEE 802.16d and 802.16e volumes in equipment. The cost effectiveness of Intel® WiMAX Connection 2250 is further enhanced by its modem designs featuring Ofer-R, Intel's single RF System on Chip, Wi-Fi/WiMAX multi-band solution.
• Because it is pin compatible with the Intel PRO/Wireless 5116 wireless modem, Intel® WiMAX Connection 2250 offers an easy upgrade path for equipment manufacturers. It enables them to design modems with the capability to evolve from 802.16-2004 to 802.16e-2005 with a software update and supports 802.16-2004 and 802.16e-2005 software stacks for flexibility in equipment design, deployment and applications.

ClearwireClearwire
• Owned by Craig McCaw
• $ 2 Billion is financing from Motorola, Intel and Others
• To date, Clearwire has been launched in mostly rural areas or small or midsize markets, including Bellingham, Honolulu; Eugene, Oregon; and Jacksonville, Florida.
• Coverage in the Seattle area stretches over a potential of 2 million people, from Marysville to Gig Harbor and as far east as Enumclaw, with some uncovered zones in between. The company has a total coverage area of 8 million people, and about 162,000 have subscribed to the service as of September.
• Clearwire has also started to provide phone service through its service in some markets. Called Voice Over Internet Protocol.
And the Winner Is ?And the Winner Is ?
• Each technology has its own merits and demerits, same is the case of WiFi, WiMax and Fixed Wireless.
StrengthsStrengths• WiFi
• Convenience: Continuous, wireless connection to a corporate network or the Internet from a variety of sites - airports, hotels, restaurants, offices, hospitals, homes etc. - improving worker connectivity and, therefore, productivity.
• Compatibility: Connections to PCs, laptops and PDAs with a wireless LAN card adhering to IEEE's 802.11b (or other) standard
• Interoperability: A non-proprietary, standardized solution • Ad Hoc mode: Direct communication between two compatible 802.11 devices without an access point (base station) • Installation speed and flexibility: Fast and easy to install, eliminating the need to cable the desktop • Scalability: Modular configurations to suit changing density requirements
• WiMax • Cost: By enabling standards-based products with fewer variants and larger volume production, it will drive the cost of
equipment down • Competition & Choice: Having standardized equipment will also encourage competition, making it possible to buy from
many sources. • Ease to deploy: Due to certified and standard equipments it makes an excellent case for plug and play installation • Reach: Can serve distances up to 25-30 Kms • Spread: Can scale to support thousands of users with a single base station.
• Cellular Fixed Wireless• Reach: Can serve distances up to 25-30 Kms • Installation speed and flexibility: Fast and easy to install, eliminating the need to digging, cabling etc • Easy to maintain: Doesn’t have components requiring high maintenance, fault rate very low, turnaround fast and easy
due to low complexity of system
WeaknessWeakness• WiFi
• Security: Opens up your network to the public anyone with WiFi compatibility has access to network. A number of problems like “war chalking" and "war driving" are new phenomenon becoming apparent only recently. This is when hackers "drive" around and "chalk" the frequency of a WiFi onto the ground for other hackers. Theoretically, anyone with an 802.11b/WiFi client device can tap into your network via a non-secure access point.
• Cost: Low volume chip production for client device makes cost of solution high, as cost depends a lot on client device which in turn depends on chip
• Range: Short range 200meters (can be enhanced using high cost proprietary devices) for standardized solution
• WiMax • Availability: Not yet widely available, encouraging numbers possible only by 2008• Infrastructure: Requires additional backhaul to feed wireless network, base stations etc • Spectrum: Uses both licensed and unlicensed band
• Cellular Fixed Wireless• Mobility: Not mobile • Scale: Cost implications not favourable for scaling • Bandwidth: Limited bandwidth • Spectrum: Uses licensed band
