attractiveness in LE Bands Main features –Ability to deploy multiple BS sectors in adjacent frequency channels –Higher coverage –Higher peak data rates with spatial multiplexing –Higher spectral efficiency –Better QoS Main technology enablers –Traffic scheduling with Tx/Rx synchronization –MIMO –UL OFDMA

P802.16h technology features Coexistence between based systems Sharing of a frequency channel between co- located operators –Coexistence Frame (CX-Frame) –Each operator may use different channel widths different PHY profiles of different cell sizes (macro, micro, nano cells) No inter-operator messages needed for basic operation

P802.16h technology features for improved coexistence with PRIMARY users SSU (Specific Spectrum Users) –Coexistence Control Channel Synchronized silence intervals enabling the cognitive detection –Examples: TV Transmitters, Wireless Mics, etc. –FCC regulations for LE TV bands: -114dBm detection levels require absolute silence NON-SSU –CXCBP - Contention-based protocol Improved coexistence with , other bursty systems No inter-operator messages needed

Communication for improved inter-system coexistence Inter-system messages –Spread information on the BS/SS radio power, antennae, location, Coexistence Frame usage, etc. –Control of interference between operators –Optimization of spectrum usage –Systems may belong to different operators Inter-system protocols –Coexistence negotiation protocol (Token Protocol, developed within the European E2R II research project) General spectrum controller is supported

Reasons for using LE spectrum Large Mobile / DSL operators do not see a business case in rural broadband –Local operators use preferably the LE spectrum, on-roof antennae Licensed spectrum is too expensive Many entities want their own network –Vertical applications Health Local government Public Private safety Utilities Combined Licensed and LE deployments –Attractive for operators not having enough licensed spectrum

Main use cases of LE bands Internet access in rural areas –Outdoor antennae for coverage (Fixed) Backhauling –Rural backhauling: FCC in perceives TV White Spaces as a suitable frequency - FCC Public and Private Safety, Homeland Security –Video surveillance, file transfers, MAPs Major event using 5GHz video surveillance: Obama’s inauguration Utility companies –Electricity, Oil and Gas companies –Sensor deployment: , , , etc. based, aggregation:

Examples where h is needed Bands below 4GHz TV White Spaces (aprox. 300MHz between 52…692MHz) –Data-base approach: resolves the Broadcast TV detection –Still required detection of wireless mics, etc. -114dBm power levels: detection is possible only with sync. silence h Coexistence Control Channel enable the operation in TVWS 2.4GHz –Reduced interference to 2.3GHz, 2.5GHz licensed bands –Europe: Requirements for Medium Access Protocol (EN V1.7.1) for spectrum sharing with other devices 3.65GHz – 3.70GHz, US –Contention-based protocol is required by FCC in the upper 25MHz –Coexistence Assurance with y was done in Coexistence TAG

Examples where h is needed Bands above 4GHz 4.9GHz US PLMR, Broadband Homeland Security –50MHz, common spectrum pool –Shared between local police, federal and local government, health institutions, fire protection, private security, industrial security, businesses security, etc PLMR registered entities with FCC –802.16h: No strict frequency assignment between entities is needed GHz to GHz –Europe: Requirements for Medium Access Protocol (EN v.1.5.1) for spectrum sharing with other devices DFS is a different requirement and imposes how the channel selection is done

802.16h as advantage of Combined licensed and un-licensed spectrum use –Additional spectrum for FREE –Requested target in the European Research FP7 – Call 4 - Objective ICT : The Network of the Future - Novel radio network architectures enabling the innovative usage of licensed, unlicensed or unused radio spectrum with the aim of radical cost- and energy-reduction. Target environments range from short to medium distance including systems based on femto-cells, ad-hoc networks and vehicular networks, up to wide-area terrestrial and satellite-based radio access networks. Frequency flexibility –Some established cellular operator have access to multiple spectrum bands, but many WiMAX operators are working with less –802.16h extends the available spectrum for WiMAX operators 3.65GHz, 5GHz, TV White Spaces Use cases –Backhauling –Femto-Cells h allows to comply with the requirement “10m +wall” for FemtoBS- MS separation

Interaction of h with m NO interaction –802.16m is for licensed operation, h is for LE No need to combine them No need to track 16m after 16h –802.16m and h are contained in different and independent chapters 16m shall use Chapter 16, as Chapter 15 is used by h A next standard revision will keep h in a separate chapter, as is the case for the OFDM PHY

Number of amendments NO limitation to 3 amendments – “Up to three amendments can be approved before the standard shall be revised, unless the base standard has been approved or reaffirmed within the past three years. In the latter case, multiple amendments may be added until the base standard is three years old.” – The limiting factor is not the number of amendments, but three years from the approval of the

Industry interest –IEEE Sponsor Ballot Clear evidence of industry interest 134 Balloters, 100 Approve, 93% approval ratio Other SBs: j – 174 people, : 183 people –More, but same order of magnitude –Operator interest 3.65GHz, where h is required for 25MHz (50%) of the spectrum –950 licensees (many nation-wide) –See announced WiMAX deployments in the back-up slides –Obama’s BB stimulus: WiMAX producers are educating the WISPs for 3.65GHz usage –Recession effects Number of people attending h meetings is reduced – and WiMAX are focused on Mobile applications Fixed deployments constitute the and WiMAX Success –> 400 Fixed WiMAX Deployments LE Bands are used for Fixed Rural deployments –Smaller companies, not attending meetings

Social impact US – President Obama’s broadband stimulus –Internet access for Rural areas –$3.7Billion, most of it going to wireless – Significant part will go to 3.65GHz – US Rural Utilities Service (RUS) program: –$2.5 billion –USDA for government-funded rural development – h impact –Broadband Internet access in rural areas, using mainly 3.65GHz “WiMAX” is the technology of choice (see back-up slides) Clearwire is “focused on completing our national rollout of 80 markets over the next 18 months, and our existing build plan isn’t predicated on our ability to secure this funding” – –Thousands of new jobs See next slide –Larger impact of the Internet access “it will fuel the new economy, help modernize the health sector through telemedicine, our education system through e-learning and our environment through telecommuting.” –

Social impact - jobs Below are examples of the overall-jobs benefit from the broadband stimulus –A part of them will be due to deployments in 3.65GHz –NEW YORK -- President Obama's $7 billion-plus plan to bring broadband to rural America could create up to 260,000 new jobs, according to researchers. Even if only 20% of this will be due to usage of 3.65GHz, the number of jobs is still > –Split by the hype factor – you still have a significant number of jobs!

Conclusion h is needed –Regulations: TVWS, 3.65GHz, 5GHz Europe –High industry interest –Social impact: Internet access for rural areas, high number of jobs -Complementary to Licensed Bands usage of –Key feature for increasing the spectrum amount -Adds cost-free spectrum for operation -No impact on m -Improved coexistence with other 802-based systems
