2 5G represents a wireless inflection point for cable companies Previous generations of mobile have focused on high speed mobility with externally deployed infrastructure with a single air interface. FCC decision to open for spectrum sharing based on small cells allows a wider number range of LTE providers FCC s decision to open up cm/mm wave spectrum for broadband communications (10/2015) as a response to the evolution towards 5G 5G is driving R&D and technology development in the mm-wave bands, enabling new use cases that go beyond mobile communications 5G emphasis on ultra high speed with cm/mm-wave small cells deployments could be a game changer for Cable Operators enabling them to deliver new mobile services both below and above 6 2 CableLabs,

3 What are US Cable s assets for 5G? 75% of Mobile Data is consumed inside buildings 5G cm/mm Wave small cells are analogous to WiFi Hot spots: handover 16Gbit/s to a macrocell? In both places Cable Operators have strategic advantages: access rights, backhaul and power 59 million US cable broadband customers with cable DOCSIS 3.0 high speed internet networks available to more than 85% of US Households DOCSIS 3.1 offers 10/1 Gbit/s while DOCSIS Full duplex will offer 10/10 Gbit/s Cable WiFi: 400K free Public Hot Spots available across the top 5 US Cable operators Community WiFi (Open WiFi): 9.8M 3 CableLabs,

4 Delineating 5G Spectrum Possible 5G Bands. (Darker shade = more certain. Not to scale.) EU/ITU 700 MHz US 600/700 MHz A range of bands is under consideration for 5G, but most are highly uncertain, particularly at the ITU Ø EU likely to follow ITU decisions at 2019 World Radio Conference FCC may make initial cm/mm Wave bands available for 5G in G spectrum availability will rely on sharing spectrum with other services CableLabs,

5 shared spectrum for future mobile Possible 5G Bands. (Darker shade = more certain. Not to scale.) EU/ITU 700 MHz US 600/700 MHz US EU / ITU Other Notes coming available in via 3-tier access model (licensed & unlicensed) Access is geo database-reliant & under initial discussion for mobile allocated for mobile in EU, but is currently a BWA/WiMax band OfCom looking at mobile in despite lack of EU initiative 3GPP has TDD standardized for WINN Forum specifying database architecture (CableLabs participating) Satellite downlink incumbents CableLabs,

6 3.5 Shared Spectrum - Democratization of LTE 3550MHz 3650MHz 3700MHz FCC Databases (Commercial Users/ Licensees) Incumbent Detection (ESC) Tier 1 DoD Radar, FSS, and Incumbent Services Tier 2 Priority Access Licensees (PAL) Tier 3 General Authorized Access (GAA) SAS 1 SAS 2 150MHz in 10 MHz blocks (73K areas across the US) At least 8 blocks are available for anyone to use Up to 7 blocks are reserved in 3 year terms (PAL) Suitable for LTE TDD terminals (3G PP Band 42/43) Domain Proxy / Network Manager Three tiers of priority for spectrum access Incumbent (Department of Defense, WISP, Fixed Sateliite) Priority (PAL) tier is licensed, dynamically assigned General (GAA) tier is effectively unlicensed Spectrum actively managed and allocated by SAS providers, including incumbent protection 3.5 radios (CBSDs) 6 CableLabs,

7 28 Possible 5G Bands. (Darker shade = more certain. Not to scale.) EU/ITU 700 MHz US 600/700 MHz US EU / ITU Other Notes Lead candidate for initial 5G band; ~850 MHz bandwidth VZ/XO and others have fixed rights; FCC likely to convert to mobile Omitted from WRC-19 consideration; international fragmentation may result Heavy research activity focused on 28 (Samsung, Ericsson, NYU, METIS/EU, etc.) FSS uplinks use this band CableLabs,

8 37 Possible 5G Bands. (Darker shade = more certain. Not to scale.) EU/ITU 700 MHz US 600/700 MHz US EU / ITU Other Notes Slated for initial US 5G allocation; 1.6 bandwidth FCC proposed hybrid licensing scheme but seems to lack industry support; may be traditionally licensed Within scope for WRC-19 Currently used for space research and fixed military links Space research operations is main international incumbency FSS has primary allocation, but no operations CableLabs,

9 39 Possible 5G Bands. (Darker shade = more certain. Not to scale.) EU/ITU 700 MHz US 600/700 MHz US EU / ITU Other Notes Slated for initial US 5G allocation; 1.4 bandwidth FCC likely to convert existing fixed assignments to mobile May be combined with 37 Within scope for WRC-19 CableLabs,

10 60 Possible 5G Bands. (Darker shade = more certain. Not to scale.) EU/ITU 700 MHz US 600/700 MHz US EU / ITU Other Notes currently available for unlicensed FCC likely to expand for 14 total unlicensed bandwidth currently available for unlicensed in EU ad enables multi-gbps performance 2.16 channel bandwidth High attenuation / short range CableLabs,

Simulations are based on the FCC allowed EIRP for the respective cm//mm bands, for some relevant US rain regions, for 2W small cells employing hybrid BF/MIMO (x2) space diversity algorithms. Ref DorinViorel, Cablelabs 28 and 38 offer circa 160m 120m ranges with 16 Gbit/s 70 offers circa 50m with 35 Gbit/s 11 CableLabs,

12 Cable Opportunities Shared Spectrum 150 MHz of shared spectrum is available for small cells with LTE TDD which could allow Cable Operators to deploy LTE small cells inside homes/offices and on outside Cable Infrastructure 5G small cells cm/mm wave band communications can offer opportunistic high-speed communications especially when coupled with clusters of small cell deployments. cm/mm wave small cells could support the same coverage as the actual LTE small cells in dense urban areas ( m cell radius) with traditional cellular bands providing the required coverage and mobility support Existing WiFi networks can be evolved into dense wireless networks 12 CableLabs, 2016 Cable has strategic assets to offer mobile support above and below 6 12

13 Cable Opportunities - 2 Fixed wireless service offerings using cm/mm wave bands To support speeds of circa Gbit/s per cell, over ranges of m, with requires deep fibre access networks and base stations in proximity to end users However, in those places Cable has a deep metro existing Fibre/Hybrid Fibre Copper footprint with similar or greater bandwidth capacities nevertheless there may be tactical opportunities for cm/mm fixed access such as rapid service provision for businesses. 13 CableLabs,

14 5G represents a wireless inflection point for cable companies 5G may present cable companies with an opportunity to become viable wireless carriers as incumbent wireless operators have to invest heavily in new technology: 5G will utilize new spectrum that will be available for auction as well as unlicensed bands Multi-Gbit/s speeds will be provided by widely distributed cm/mm wave small cells where Cable has WiFi assets Both incumbents and potential cable players will need to purchase new radio access equipment Core networks will be redesigned with new virtualization technologies Cable companies are well positioned to take advantage of this transformation: Experience with provisioning widely distributed access points both LTE and WiFi Existing WiFi networks can be evolved into dense wireless networks Ability to leverage existing deep metro fibre/hybrid Fibre Copper footprint with external and internal placement of small cells Fixed-mobile convergence will be a central theme for efficient and effective 5G network design 14 CableLabs,
