WiMAX: The Cure for Rural Broadband



Broadband penetration in rural areas across the world has lagged far
behind than that in urban areas due to multiple reasons which make
providing coverage in these areas economically non-viable. However, with
the efforts of various governmental agencies and the advent of new high
speed mobile broadband technologies such as WiMAX, this situation is
rapidly changing.

This
whitepaper provides an overview of the issues surrounding rural
broadband, the impact of WiMAX to remedy these, and the topologies which
can be adopted by service providers for economically viable deployments.

FCC Opens 25 MHz OF Spectrum for Mobile Broadband

The FCC adopted rules that will make available 25 megahertz of spectrum for mobile broadband service in much of the United States.


Specifically, the newly adopted Order amends the Wireless Communications Service (WCS) rules to immediately make 25 megahertz of spectrum available for mobile broadband services. The existing WCS rules constrain operations to fixed services, but the Commission found today that those rules can be revised to allow mobile broadband services without risking harmful interference to neighboring operations.


The FCC also adopted enhanced build-out requirements for WCS licensees, to ensure that the promise of mobile broadband is realized. These requirements are designed to spur investment that will promote the deployment of innovative mobile broadband services across the country.


Together, the Orders establish a regulatory framework for the co-existence of WCS and SDARS licensees in the 2.3 GHz frequency band in the following manner:

  • Mobile and portable broadband devices: Mobile and portable station power levels are permitted up to 250 mW average equivalent isotropically radiated power (EIRP) per 5 megahertz in WCS Blocks A and B and in the portions of WCS Blocks C and D that are separated by 2.5 megahertz from the SDARS band edges; duty cycle limitations and automatic transmit power control (ATPC) will apply; out of-band emissions (OOBE) requirements on WCS mobile and portable devices are also relaxed.

  • WCS base and fixed stations: Base and fixed stations in WCS Blocks A and B are permitted to operate with up to 2 kW average EIRP per 5 megahertz but stations in the C and D blocks remain limited to the 2 kW peak EIRP level currently specified in the Rules; WCS base and fixed stations' OOBE are also relaxed; a notification process with SDARS and coordination process with aeronautical mobile telemetry (AMT) users are also established.

  • Performance requirements for WCS licensees: For mobile and point-to-multipoint services, WCS licensees must serve 40 percent of a license area's population within 42 months, and 75 percent within 72 months. For fixed point-to-point services, WCS licensees must construct and operate 15 point-to-point links per million persons in a license area within 42 months, and 30 links within 72 months, together with a minimum payload capacity to ensure that the spectrum is used intensively. Licensees will not be required to satisfy submarket construction requirements.

  • WCS Coordination with Flight Testing Service. In those license areas where WCS licensees must coordinate with aeronautical mobile telemetry receive sites to serve a significant percentage of a market's total population, alternative requirements apply for mobile and point-to-multipoint services. Specifically, affected licensees must serve 25 (rather than 40) percent of the population within 42 months, and 50 (rather than 75) percent within 72 months.

  • SDARS terrestrial repeaters: Permanent rules are established for the operation of SDARS terrestrial repeaters. Repeaters operating up to 12 kW average EIRP will be authorized under a blanket licensing regime. The Commission also denies petitions for reconsideration of the 1997 SDARS Order filed by the Consumer Electronics Manufacturing Association (CEMA) and the Cellular Phone Taskforce.


The National Broadband Plan recommends that the Commission make 500 megahertz of spectrum available for broadband use in the next 10 years, including 300 megahertz for broadband use in the next five years.

FCC Approves Verizon-Frontier Deal

The FCC approved the transfer of 4.8 million lines in primarily rural and smaller-city areas to Frontier Communications from Verizon Communications.



The FCC believes the transaction will help advance the goals of the National Broadband Plan by bringing broadband to millions of consumers, small businesses, and anchor institutions in 14 states across the West, Midwest, and South.


To gain the approval, Frontier has committed to deploy broadband with actual speeds of at least 3 Mbps downstream to at least 85 percent of transferred lines by the end of 2013, and actual speeds of at least 4 Mbps downstream to at least 85 percent of the transferred lines by the end of 2015, with all new broadband deployment offering actual
speeds of at least 1 Mbps upstream.


In addition Frontier will launch an anchor institution initiative to deploy fiber to libraries, hospitals, and government buildings, particularly in unserved and underserved communities.

Fujitsu and University of Tokyo Develop 25 Gbps Quantum Dot Laser

Fujitsu Laboratories and the University of Tokyo have developed the first quantum dot laser capable of 25 Gbps transmission. Researchers believe the technology can be scaled to 100 Gbps and above.


Quantum dot lasers are semiconductor lasers which employ quantum dots - nanometer-sized semiconductor particles as an active material for lasing. The researchers cite several advantages over other types of semiconductor lasers, such as being less sensitive to temperature fluctuations, while offering tremendous advances over previous semiconductor lasers in terms of lower power consumption, greater transmission distances, and faster speeds.


Quantum well lasers, which have conventionally been used as optical sources for data communications, have a problem of dramatic increases in power consumption attributable to increased driving current when temperatures rise. The quantum dot laser developed by Fujitsu Laboratories and the University of Tokyo uses 3-dimensional (3D) semiconductor nanostructures to produce quantum effects, thus giving it excellent characteristics, including stable operation over a range of temperatures and low power consumption. However, the quantum dot laser had been limited to handling data transfer speeds up to 10 Gbps.


In order to increase the speed of quantum dot lasers, it was necessary to increase the laser's optical gain, which in turn required an increase in the number of underlying quantum dots. New quantum dot fabrication technology was developed and applied. Layers of quantum dots with a higher density than conventionally employed were then stacked, thereby doubling the laser's operation speed and enabling a significant improvement over previous technologies. The result was a quantum dot laser capable of high-speed operations at 25 Gbps.


Fujitsu and Fujitsu Laboratories have developed this technology in an industrial-academic collaboration with Professor Yasuhiko Arakawa's laboratory of the University of Tokyo. Part of this research belongs to a project contracted to the Photonics Electronics Technology Research Association (PETRA) by the New Energy and Industrial Technology Development Organization (NEDO), while part of the research was carried out under Japan's Ministry of Education, Culture, Sports, Science and Technology's Special Coordination Funds for Promoting Science and Technology.http://jp.fujitsu.com/labs/enhttp://www.u-tokyo.ac.jp/index_e.html

Verizon Expands Fleet of Alternative-Energy Vehicles

Verizon unveiled five hybrid aerial-lift trucks, the first of 160 alternative-energy vehicles that the company will add to its fleet in New York this year.


The five vehicles, also known as bucket trucks, have batteries that help power the engine and also provide the sole power for the mechanical boom that raises a four-sided platform, or "bucket," to enable a technician to work on overhead telephone lines or other equipment. In the traditional versions of Verizon's bucket trucks, the mechanical booms are powered by the trucks' gasoline or diesel engines.


Heavy-duty chargers that plug into an electrical outlet are used to recharge the hybrid trucks' batteries. The batteries will be recharged at night, when power demand from the nation's grid -- generally the cleanest and most efficiently produced energy -- is low.


Verizon noted that it is rolling out more than 1,100 alternative energy vehicles across the country this year, and increasing use of biodiesel and flex-fuel (E85) to power 470 vehicles. The company will operate approximately 250 alternative energy vehicles in New York by the end of 2010.http://responsibility.verizon.com/

Infinera Targets 100G Coherent System for 2012

Infinera disclosed plans to release next-generation optical systems based on 100 Gbps coherent transmission in 2012. The company's product development team has been working on both 40G and 100G solutions, including key optical and electrical enabling technologies. Recently, the engineering team demonstrated the transmission of a 100G signal over 1600 kilometers of fiber using coherent modulation technology. This milestone has enabled Infinera to accelerate its timetable for a 100G solution.


The new 100G systems will be based on Infinera's next-generation photonic integrated circuits (PICs), which integrate the functionality of hundreds of optical devices to provide 500 Gbps) of optical capacity on a single pair of chips (500G PICs). Infinera said these coherent detection systems will push ultra-long-haul fiber capacity to 8 Tbps.


Infinera is also planning to add non-PIC based coherent capability to its DTN system in 2011, to meet the needs of customers who require a 40G solution.


"We expect that Infinera's 100G system will reach the market at a time that enables 100G mass adoption," said Infinera CEO Tom Fallon. "In addition, Infinera 100G networks will offer very significant competitive advantages. Advanced features like digital bandwidth management and Bandwidth VirtualizationTM, which customers expect from Infinera, will continue to deliver valuable benefits in our intelligent networks. We believe that traditional muxponder-based DWDM systems become even more inefficient when carrying a wide range of lower-speed services over 100G wavelengths."http://www.infinera.com

FCC Issues Pole Attachment Order

The FCC issued an Order clarifying the statutory right of communications providers to use the same space- and cost-saving techniques that pole owners use, such as placing attachments on both sides of a pole. The Order also establishes that attachers have a statutory right to timely access to poles.


The FCC is also seeking public comment on revising pole attachment rates to make them as low and as close to
uniform as possible, reducing the disparity between current telecom and cable rates. The FCC said the current practice of different rates for different types of firms using the same space on a pole makes little sense when the cost of providing the space is the same to the utility pole owner. Disparate rates can affect investment decisions and product offerings, resulting in fewer competitive choices for consumers.


"The National Broadband Plan demonstrated that the U.S. is lagging globally in
broadband, and that rapid progress is essential to our global competitiveness and to U.S. world
leadership in innovation in the 21st century. The National Broadband Plan also demonstrated that
there's no silver bullet to achieve these goals -- indeed, that many key rules and policies will
involve the 'blood and guts' of broadband deployment. Our Order today is in this category -- I
believe it will yield real results for real people: faster, cheaper, and more widely available
broadband," stated FCC Chairman Julius Genachowski.http://http://

Tektronix Debuts Iris Performance Intelligence

Tektronix Communications unveiled its Iris Performance Intelligence (IPI) solution for end-to-end analysis and reporting capabilities combined with a KPI/KQI modeling engine that allows operators to better link desired business outcomes to events that occur at the network level.


The IPI is designed to provide multiple departments within an operator the ability to monitor and report on applications using a real-time and historic KPI dashboard. This provides the capability to identify network, service and IP performance issues, drill-down to their root cause, and proactively fix the issue before customers are even aware there is a problem. IPI allows multiple departments within an operator to develop their own Key Quality Indicators based on the industry standard categories of accessibility, retention, integrity and performance.


Applications within IPI include voice and data applications such as Web Browsing, E-mail, SMS, MMS and other services traversing on the data/IP network. User-defined applications can be associated to specific URLs, IP addresses and port numbers, application protocols and APNs. IPI can also monitor the performance of key network elements associated with legacy, 3G and 4G/IP networks.


"Realizing that every customer and every network is different, Tektronix Communications developed its Iris Performance Intelligence solution to enable specialized user workflows for unprecedented speed and efficiency in proactive network management and root cause path analysis," said Mark Driedger, vice president and general manager of Tektronix Communications' Network Management business.

Alcatel-Lucent's LTE Supports Live Video Feed for Sail Boat Race

Alcatel-Lucent LTE network solution is supported a live, broadcast video feed of the World Match Racing Tour's German Grand Prix, an international sailing boat race being held this week on Lake Constance, Germany.


Live feeds from Formula-1 and cycling races, soccer games or track and field events are common today. However, the effort involved to get all video shots transmitted to the production studio is significant. Expensive satellite links, proprietary trunk radio systems, and even helicopters with mobile radio antennas are used for this very complex and costly operation.


Alcatel-Lucent said this sailing event demonstrates the LTE technology can replace a traditional set-up for streaming video. For this project, Alcatel-Lucent has set up a complete end-to-end network covering the 4-5 km racing event area -- spanning Lake Constance, Kressbronn as well as the city of Langenargen where the TV production centre is located.

The SIP Forum and i3 Forum Partner on Fax Interoperability

The SIP Forum and the i3 Forum are collaborating to spur the interoperability of SIP-based carrier services, including Fax-over-Internet-Protocol (FoIP) interoperability on a global basis.


The partnership brings together two premier organizations tasked with similar missions -- to accelerate the deployment of IP-based communications worldwide -- but with different stakeholder communities. The SIP Forum features a broad membership of primarily telecom applications, services, and infrastructure vendors, as well as a growing list of US-based cable operators and service providers. The i3 Forum's global membership focuses on international service providers.


As done since last January, the SIP Forum leadership and its FoIP Task Group will continue working with i3 Forum membership committees on joint technical initiatives pertaining to FoIP. Collectively, the two groups will address key interoperability issues pertaining to the deployment of fax services, specifically ITU-T T.38, in SIP-based networks. The challenges surrounding IP-based fax and the use of T.38 make it difficult for users to determine if T.38 can or will work reliably and thus offer a viable alternative to traditional TDM-based fax transport.

FCC Releases Wireless Competition Report

Average monthly mobile voice usage in the U.S. has declined as data usage has soared, according to the FCC's newly released 14th annual report on the state of competition in the mobile wireless industry.


Industry concentration has increased over the past five years, with the two largest providers, AT&T and
Verizon Wireless, now controlling 60 percent of both subscribers and revenue and gaining share
(accounting for 12.3 million net additions in 2008 and 14.1 million during 2009).


The coverage analysis suggests that approximately 284 million people, or 99.6 percent of the U.S. population, are served by one or more mobile voice providers. Approximately 281 million people, or 98.6 percent of the population, are served by at least two mobile voice providers.


The study also indicates that U.S. consumers pay relatively more on a monthly basis than most other countries but also consume more airtime and enjoy lower unit rates.


Some additional trends highlighted in the report:


Innovation in and around devices and applications: Handset manufacturers have introduced a
growing number of new smartphones -- 67 in 2008 and 2009 -- that provide mobile Internet
access and other data services, and provide many of the functionalities of personal computers.


Transition to a data-centric market: Data traffic has grown significantly, with the increased
adoption of smartphones and data consumption per device.


Role of spectrum for mobile broadband: Especially as mobile wireless broadband usage grows, access to spectrum becomes increasingly important for competition. While many wireless service providers have access to significant amounts of mobile spectrum, most of the spectrum below 1 GHz, in both the cellular band and the 700 MHz band, is not widely held.


Maturation of the mobile voice segment: As of the end of 2008, 90 percent of Americans had a mobile wireless device.


Continued industry concentration: There appears to be increasing concentration in the mobile wireless market. One widely-used measure of industry concentration indicates that concentration has increased 32 percent since 2003 and 6.5 percent in 2008.


Robust capital investment but declining relative to industry size: Providers continue to invest significant capital in networks, despite the recent economic downturn. One source reports capital investment at around $25 billion in both 2005 and 2008, while another shows that capital investment declined from around $25 billion to around $20 billion during the same period.


As noted by Commissioners Robert McDowell and Meredith Attwell Baker, for the first time since 2003, the report omitted the conclusion that the wireless marketplace is "effectively competitive." On this point, Kathleen Grillo, Verizon senior vice president of federal regulatory affairs, commented: "The U.S. has the most intensely competitive wireless market on the planet, and it's becoming more competitive by the day. New devices and new apps hit the market constantly. Prices keep falling and usage keeps rising."
