3 Problem: Digital Divide has Resulted in an Opportunity 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 This has created a DIGITAL DIVIDE and an OPPORTUNITY Other Machine to Machine Applications will Drive Up the Volumes Slide 3

5 High Range and NLoS Operation are Necessary for Broaband to Rural Range: VHF/ UHF Bands and Television Whitespaces with appropriate transmit / receive power allowance are ideally suited to deploy large Regional Area Networks (RANs) due to favorable propagation characteristics. Deployment of Wireless Regional Area Networks with greater range allows more users per Base Station, resulting in a viable business model 4 Watts Omni 5.8 GHz 2.4 GHz 900 MHz VHF / UHF and TV Whitespaces Slide 5

7 Television Whitespaces: A New Hope Southern Ontario Canada More Channels Available in Rural Areas Source: Gerald Chouinard, CRC and Industry Canada Urban Areas TV Channel Availability for Broadband Legend Available TV channels TV Channels in VHF / UHF bands have highly favorable propagation characteristics Analog TV will be transitioned world-wide to Digital TV which is more spectrum efficient. 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.

8 What can Television Whitespaces do? Wireless Regional Area Networks such as IEEE systems using TV Whitespaces can connect rural areas in emerging markets. Television Whitespaces (TVWS) will allow broadband wireless access to regional, rural and remote areas under Line of Sight (LoS) and Non Line of Sight (NLoS) conditions. Other Applications: Triple play for broadcasters (e. g. video, voice and data), Smart grid Cheap backhaul using multi-profile RAN stations Off-loading cellular telephony traffic to un-licensed spectrum, Distance learning, civic communications, regional area public safety and homeland security, emergency broadband services, Monitoring rain forests, monitoring livestock, border protection, Broadband service to multiple dwelling unit (MDU), multi tenant unit (MTU), small office home office (SoHo), campuses, etc. Slide 8
