"Wireless broadband services transmit data and information at high speeds using wireless links. Such data and information can include a wide range of content and applications that are accessed over the Internet, including web sites, e-mail, instant messaging, music, games, or data stored on a corporate server. Wireless broadband Internet access services can be provided using mobile, fixed, or portable technologies. These technologies can transmit data over short, medium, or long ranges, and can use licensed spectrum and/or unlicensed devices. Some of the wireless broadband Internet access technologies in use today include CDMA 1x EV-DO (EV-DO), Wideband CDMA (WCDMA) with High Speed Downlink Packet Access (HSDPA), and Wi-Fi.
"Mobile broadband technologies enable subscribers to access the Internet while traveling at high speeds via a mobile handset, a smartphone, or a wireless modem card connected to a laptop computer or PDA. Mobile broadband technologies used by carriers in the United States, such as EV-DO and WCDMA/HSPDA, are capable of transmitting data at speeds ranging in excess of 400 kbps.
"Technologies such as Orthogonal Frequency Division Multiplexing (OFDM) enable providers to offer wireless broadband services that are often considered "portable" in nature. Providers using licensed spectrum in the BRS/EBS and WCS spectrum currently offer services that enable their subscribers to access the Internet with portable, "plug-and-play" modem devices that attach to a desktop or laptop computer and do not require a direct line-of-sight between the transmitter and the receiver. Customers can transport these modem devices to other locations in the provider's coverage area where a network signal is available, though they may not have the ability to maintain a connection while traveling at high speeds with handoff. Most devices are currently manufactured in accordance with vendor-specific, proprietary standards; however, standardized, 802.16 WiMAX equipment is being developed. Typical downstream speeds for portable wireless broadband services range from 768 kbps to 1.5 Mbps, and networks can extend five to 30 miles.
"Wireless broadband Internet access services offered over fixed networks allow consumers to access the Internet from a fixed point while stationary and often require a direct line-of-sight between the wireless transmitter and receiver. These services have been offered using both licensed spectrum and unlicensed devices. For example, thousands of small Wireless Internet Services Providers (WISPs) provide such wireless broadband at speeds of around one Mbps using unlicensed devices, often in rural areas not served by cable or wireline broadband networks. These networks typically have a reach of one to five miles, and customers must have a rooftop antenna that can establish a line-of-sight connection with the network transmitter.
"Wireless Local Area Networks (WLANs) provide wireless broadband access over shorter distances and are often used to extend the reach of a "last-mile" wireline or fixed wireless broadband connection within a home, building, or campus environment. The range of a typical WLAN is approximately 100 to 300 feet. The most prevalent WLAN equipment is manufactured in accordance with the IEEE 802.11 family of standards, commonly known as "Wi-Fi," short for wireless fidelity. Wi-Fi networks use unlicensed devices and operate under Part 15 of the FCC's rules applicable to frequency hopping systems in the 2.4 and 5 GHz bands. Wi-Fi networks can transfer data at speeds of up to 11 Mbps for 802.11b and up to 54 Mbps for 802.11a and 802.11g. They can be designed for private access within a home or business, or can be used for public Internet access at "hot spots" such as restaurants, coffee shops, hotels, airports, convention centers, and city parks.
"Personal area network technologies, such as Bluetooth, ZigBee, and Ultra-Wideband (UWB), are used to transmit data over very short distances, such as a few meters or across a room. They are often used to provide interconnectivity among mobile devices and between mobile and desktop devices, serving as a replacement for wires and cables that connect different electronic devices together. The data transfer rates range from around 300 kbps with ZigBee to 100 Mbps with UWB."

"Wireless providers are deploying new, faster, and more spectrally-efficient technologies for mobile broadband, known as 4G LTE. 6 American consumers have been quick to adopt 4G LTE technology, securing the United States’ position as the world leader in LTE adoption. In the 15th Annual Mobile Wireless Competition Report, the Commission observed that there were no commercial LTE launches in the United States as of August 2010. 7 By the end of 2011 though, U.S. LTE subscribers numbered 5.6 million, accounting for 64% of the roughly 9 million LTE subscribers worldwide. 8 Deloitte predicts that U.S. investment in 4G networks during 2012-2016 could be $25-$53 billion. 9 Aggressive LTE network build-out by U.S. providers has been a driving force in customer take-up and we anticipate that this trend will continue. Analysts anticipate that globally, LTE subscribership will reach at least 400 million by 2016. We will continue to follow global LTE trends for future IBDRs."
"With this progress, the United States has regain ed its role as a global leader in and around mobile broadband. More than 80% of smartphones sold globally run on U.S. operating systems, up from less than 25% three years ago. 11 As the first adopters of 4G LTE, the U.S. is the global test bed for wireless technology and services. In 2011, venture in vestment in Internet start-ups reached its highest levels since 2001. 12 The apps economy, a $20 billion industry that barely existed five years ago, has created nearly 500,000 jobs."

Wireless broadband services are subject to minimal regulation by the FCC. Wireless technologies that use unlicensed radio band spectrum (such as Wi-Fi and Wi MAX) are subject to technical requirements in the FCC’s rules that are intended to prevent interference with FCC licensed services.54 Advanced wireless services that use licensed spectrum (such as cellular phones, PDAs, and wireless modem cards) are subject to the relevant FCC rules for the particular licensing regime.55 The issue of whether wireless broadband will be subject to additional regulation has not been fully resolved.
The FCC’s Wireless Broadband Access Task Force addressed this issue in 2005 and recommended that the FCC “apply a deregulatory framework – one that minimizes regulatory barriers at both the federal and state levels – to wireless broadband services.”56 Accordingly, the Task Force recommended that the FCC consider classifying wireless broadband as an “information service.”57 Under the Communications Act, “information services” are not subject to the Communications Act’s Title II common carrier requirements for “telecommunications services.”58 As noted by the Task Force, however, even with a deregulatory framework, it is likely that certain regulatory requirements will be imposed on wireless broadband technologies.59 One factor that may affect the regulation of wireless broadband is the possibility of federal legislation that would overhaul the Communications Act in order to address the convergence of telecommunications technologies.

Spectrum Policy Task Force
Derived From: Kenneth Carter, Ahmed Lahjouji, Neal McNeal, Unlicensed and Unshackled: A Joint OSP-OET White Paper on Unlicensed Devices and Their Regulatory Issues, OSP Working Paper 39 p 11 (May 2004)
In a more recent effort to address spectrum access issues, the FCC established a Spectrum Policy Task Force in June 2002. The Task Force was composed of senior staff members from several FCC Bureaus and Offices who were asked to assist the FCC in identifying and evaluating changes in spectrum policy necessary to reflect advances in technology that were likely to increase the public benefits from spectrum use. In November 2002, the Task Force released its findings. Its report noted that, while certain frequency bands are heavily used, many bands either are not in use in all geographic areas or are only heavily used part of the time. Furthermore, the Task Force determined, that these characteristics served to limit access to available spectrum and that such limitations are a more significant problem than the physical scarcity of spectrum itself. The report identified three unique approaches to spectrum policy based on the establishment of a set of legal rights: 1) an exclusive use approach; 2) a commons approach; and 3) a command-and-control approach. 19
The Task Force urged that the FCC evolve its spectrum policy from its traditional "command and control" model to a more market-oriented approach to achieve spectral efficiency. The Task Force set out four key recommendations to accomplish this policy reform. Recommendations include:
1. Migrate toward more flexible, consumer-oriented policies. The Task Force recommended that the Commission evolve its spectrum policy toward more flexible and market-oriented spectrum policies that will provide incentives for users to migrate to more technologically innovative and economically efficient uses of spectrum.
2. Adopt quantitative standards to provide interference protection: interference temperature. The Task Force recommended the creation of a quantitative standard for acceptable interference that provides both greater certainty for licensees and greater access to unused spectrum for unlicensed operators.
3. Improve access through the time dimension. The Task Force found that new technological developments now permit the Commission to increasingly consider the use of time, in addition to frequency, power and space, as an added dimension permitting more dynamic allocation and assignment of spectrum usage rights. This would provide access to unused or underused spectrum through time-sharing of spectrum between multiple users and lead to more efficient use of the spectrum resource.
4. Shift from "command and control" model to exclusive and commons models. The Task Force recommended that the Commission base its spectrum policy on a balance of three spectrum rights models: an exclusive use approach, a commons approach and, to a more limited degree, a command-and-control approach. While the command-and-control model currently dominates today's policy, the Task Force recommended altering the balance to provide greater use of both the exclusive use and commons models throughout the radio spectrum and limiting the use of the command-and-control model to those instances where there are compelling public policy reasons, such as some public safety applications. To the extent feasible, more spectrum should be identified for both licensed and unlicensed uses under flexible rules and existing spectrum that is subject to more restrictive command-andcontrol regulation should over time be transitioned to these models.
On of the most notable of the Task Force's recommendations, from an unlicensed device perspective, is that it urges the adoption of an "interference temperature." The new metric would allow the FCC to quantify and manage interference on a band-by-band basis, by establishing limits on the noise environment in which receivers would be required to operate. To the extent, however, that the interference temperature in a particular band is not reached, the report argues, users who emit energy below that temperature could operate more flexibly - with the interference temperature serving as the maximum cap on the potential RF energy any device could introduce into the band.
