The challenge of providing enough capacity for mobile users in future networks asks for innovative networks. The paper presents home base stations owned by the user as an alternative to femtocells owned by the network operators.
Coverage aspects are linked to business perspectives, and show that network costs can be reduced by more than 70% through the introduction of prosumer base stations.

  • Telecom Line, May 2010 The future of Telecom: Customers becoming their own operator represented by: on behalf of Josef Noll Movation AS Chief Technologist, Movation AS, MoMo - Mobile Monday Professor, University of Oslo/UNIK josef.noll@movation.no CWI - Center for Wireless Innovation Norway Nerd & Professional www.movation.no, www.mobilemonday.no, cwin.no, www.unik.no, www.innovationstockexchange.no Telecom Line - May 2010 - Josef Noll torsdag 20. mai 2010

  • Postulation “Let the user own his own network, and your revenue as a Telecom operator will increase” Stoneage: • A phone is related to a household • The PC/Laptop belongs to your company • Your Mobile Phone is owned by your company still remaining SMS • The Network is owned by an operator versus video but • An operator can’t charge for mobile costs “Open Innovation in a Networked Knowledge Society” 4 Telecom Line - May 2010 - Josef Noll torsdag 20. mai 2010

  • B4G - the service aspect • Can mobile operators provide sufficient bandwidth at home/in the office? • Service experience from mobile broadband/LTE roll-out – 70-80% of all mobile broadband users are inside a building – fixed services like TV, video, streaming are more dominant – USA today: more data/apps traffic than voice traffic [source: J. Waring, 2010] • Mobile modems are part of home/business infrastructure – iPad, set-top box, TV, projector – iPhone (AppStore), Android: Widgets, Applets – streaming: YouTube, Spotify, mobile-TV, Revenue does not relate to bandwidth 6 Telecom Line - May 2010 - Josef Noll torsdag 20. mai 2010
  • 5G access - business considerations • Access challenge: More bandwidth with less revenue • The radio dilemma Capacity increase related to 900 MHz capacity – frequency !, bandwidth ! 3 relative Capacity increase – frequency !, range ↓ – outdoor to indoor 2 outdoor • The business dilemma 1 outdoor to indoor – 4G access is expensive (range) – changing access means 0 900 1800 2100 2600 loosing revenue frequency [MHz] 7 Telecom Line - May 2010 - Josef Noll torsdag 20. mai 2010
  • LTE radio dimensioning Aggregated data rate > 65 Mbit/s > 20 Mbit/s > 7 Mbit/s > 1.2 Mbit/s Interference at the edge of the network, can be resolved through intelligent frequency reuse 8 Telecom Line - May 2010 - Josef Noll torsdag 20. mai 2010
  • Indoor dilemma • Coverage [Motorola 2009] – 38% of users > 20 Mbit/s – 32% of users 7...20 Mbit/s – 30% of users 1.2...7 Mbit/s 70-80% indoor usage 70-80% indoor usage 70% indoor users means 30% reduction of cell capacity, and only 45% of satisfied users 9 Telecom Line - May 2010 - Josef Noll torsdag 20. mai 2010
  • Indoor dilemma • Coverage [Motorola 2009] – 38% of users > 20 Mbit/s – 32% of users 7...20 Mbit/s – 30% of users 1.2...7 Mbit/s 70-80% indoor • Indoor coverage usage – 70-80% of traffic from indoor – decreased signal quality – users experience less bandwidth than promised 16% 17% 32% 35% – 35% of users out of service coverage 70-80% indoor usage – Operators has up to 30% reduced cell capacity 70% indoor users means 30% reduction of cell capacity, and only 45% of satisfied users 9 Telecom Line - May 2010 - Josef Noll torsdag 20. mai 2010
  • Telenor expectations source: Jørgen Grinnes, Telenor, Dec 2009 • NPT has opened for “cognitive radio” (April 2010) in 800 band Enough capacity in LTE 800 network? Bad indoor coverage with LTE 2600. 10 Telecom Line - May 2010 - Josef Noll torsdag 20. mai 2010
  • Alt 1: Over-dimensioning • Increase of Tx – 10 dB increased Tx -> 70% increased coverage – cell overlap causes interference – total network capacity is reduced Over-dimensioing costs too much network capacity 11 Telecom Line - May 2010 - Josef Noll torsdag 20. mai 2010
  • Alt 2: Femtocells 16% 17% 32% 35% service availability without femtocells • Femtocell – operator-owned – full QoS control – enable hand-over – equipment – transmission – installation and deployment cost – site acquisition or rental cost – operation and maintenance cost • Customer perspective – DnBNOR, FFI.... provide only “Telenor” coverage? – WLAN hotspot: “freedom to select” Operator-owned femtocells for indoor coverage 12 Telecom Line - May 2010 - Josef Noll torsdag 20. mai 2010
  • Alt 2: User-owned home BS • Home base station (BS) • Conditions – 70-80% indoor usage – spectrum ownership: 2600 GHz – voice produced on 3G should be “unlicensed” (NPT, EU,...) – mainly data usage with application- – Alt: “Give away” guard band spectrum based hand-over – adaptive signal adaptation – “break than make” – provision to all customers, “home authentication” • Collaborative business – “0%” OpEx costs for operators – known from NFC - “trusted service manager” (TSM) – trust relation and “prosumer” approach • Maintenance cost reduction – 12 %/year for an operator-owned – user owned: 2 %/year customer maintenance support Home BaseStations for Increased User-Experience 13 Telecom Line - May 2010 - Josef Noll torsdag 20. mai 2010
  • Alt 2: User-owned home BS OpEx and CapEx calculations based on 40% market share “free provisioning” of home base stations [source: H. Claussen, 2007] Annual Network Costs [$] total costs percentage of customers with home-BS Total network cost reduction more than 70% with user-owned base stations 14 Telecom Line - May 2010 - Josef Noll torsdag 20. mai 2010
  • Conclusions • 70-80% of 3G/”4G” from indoor users outdoor out/inn >20 Mbit/s 38 % 16 % 7-20 Mbit/s 32 % 17 % 1.2-7 Mbit/s 30 % 32 % -35% • Femtocell – effective if >30% penetration – limited user experience “where is my operator” • User-provided Femto – “no maintenance” – requires trust relations • Collaborative Radio Collaborative Radio & Operation, the driver for cost-effective future wireless broadband networks 16 Telecom Line - May 2010 - Josef Noll torsdag 20. mai 2010
