1 Mobile Broadband of Deutsche Telekom AG LTE to cover White Spaces Karl-Heinz Laudan Deutsche Telekom AG 16 June 2011

2 Spectrum is the basis for any mobile radio communication service Satellites (1,5 2,2 GHz) big distances low capacity WLAN (2,4 GHz) high data rates small cells GSM,UMTS, LTE (800 MHz 2,6 GHz) Wide Area Network high data rates universal access Bluetooth (2,4 GHz) very small cells small, low power consumption low power devices 2

3 but: Radio Spectrum is a very scarce resource Only a small part (UHF) is commercially viable for White spaces Mobile service and TV- Broadcast in UHF-band Broadcast MHz 450 MHz LTE GSM GSM/LTE UMTS LTE 800 MHz 900 MHz 1800 MHz 2100 MHz 2600 MHz (in future: LTE) (in future: LTE) Low frequencies few MBit/sec - but big range, good inhouse coverage for coverage needs below 1 GHz for capacity needs beyond 1 GHz High frequencies many MBit/sec but low range, bad inhouse coverage Source: Ofcom 1000 MHz = 1 GHz

4 Broadband with spectrum below 1 GHz only 1/3 of the costs 2100 MHz 2100 MHz 700 MHz 2100 MHz UHF- Band cell radius ~ 10 km UMTS-Band cell radius ~ 5.5 km Mobile Broadband can close the Digital Divide 4

5 Evolution of mobile standard from GSM to LTE from just voice to extensive data usage kbps kbps Mbps Mbps 30 (avg) to 170 (peak) Mbps GSM GPRS/ EDGE UMTS R99, 1st version of 3G HSDPA Downlink Enhanced 3G HSPA / HSPA+ Downlink / Uplink Enhanced 3G NGMN - LTE Broadband radio, IP based architecture Future Wireless Cellular Enhanced Mobile Services Multimedia Cellular Enhanced Multimedia Mobile Optimised Multimedia Mobile Broadband Mobile Communication GSM (GPRS / EDGE) 3G - UMTS Enhanced UMTS Optimised UMTS NGMN - LTE 5

6 LTE can operate in different frequency bands and with different band width performance determined by bandwidth f1 downlink FDD (Frequency Division Duplex) Forward and backward link on two different, so called paired, frequencies Transmitter/ Receiver f2 uplink Transmitter/receiver TDD (Time Division Duplex) Forward and backward link on the same frequency but on different time slots : Channel bandwidth LTE Performance: The higher the channel bandwidth the higher the achievable data rate. 1.4 MHz 3 MHz 5 MHz 10 MHz 15 MHz 20MHz currently maximum LTE channel bandwidth 6

7 Success factors of LTE Killer Experience Backhaul Ecosystem High throughput and capacity 170 Mobile high speed needs high capacity backhaul Early availability of complete Eco-system Low latency Legacy compatibility Re-use of existing network structures (grid) Automation Self organising networks (SON) Spectrum Sufficient spectrum for coverage and capacity Self configuring Self testing Self optimizing Self monitoring Self detecting Self diagnosing Self healing 400 MHz 1400 MHz 1700 MHz 2700 MHz 7

8 Spectrum assignments in Germany after the Auction 2010 Telekom, Vodafone and Telefonica O2 achieved 10 MHz blocks in 800 MHz MHz 5 MHz 5 MHz 5 MHz 5 MHz 5 MHz MHz 5 MHz 2,6 MHz 7,4 MHz 6,2 MHz 4,4 MHz 3,8 MHz T-Mobile Vodafone O2 E MHz 5 MHz 5 MHz 5 MHz 5 MHz 17,4 MHz 5,4 MHz 5 MHz 17,4 MHz MHz TDD 5 MHz TDD 5 MHz TDD 5 MHz TDD 10 MHz 5 MHz 5 MHz 10 MHz 5 MHz 5 MHz 10 MHz 10 MHz 14 MHz TDD MHz 5 MHz 5 MHz 5 MHz 5 MHz 5 MHz 5 MHz 5 MHz 5 MHz 5 MHz 5 MHz 5 MHz 5 MHz 5 MHz TDD 5 MHz 5 MHz 5 MHz 5 MHz 5 MHz 5 MHz 5 MHz 5 MHz 5 MHz 5 MHz

9 License conditions for the 800 MHz band request prioritisation for rural areas w/o broadband access Digital Dividend MHz GSM "D-Net" MHz License conditions LTE 800 Broadband coverage GSM "E-Net" MHz IMT-2000 (UMTS) MHz IMT-2000 ext. band 2600 MHz Priority classes Prio 1: < inhabitants Prio 2: inhabitants Prio 3: inhabitants Prio 4: > inhabitants Step wise approach to cover high priority areas first. 90% population coverage has to be achieved before starting in the next area of lower priority Target: 50% pop-coverage until January 1, but: existing broadband access counts (fixed or mobile) also competitors taken into account 50%.. 90% of households >1Mbps >90% of households <1Mbps <50% of households >1Mbps 9

10 Issues to be taken into account while deploying LTE800 Cross border coordination (difficulties concerning deployment) Coordination in border areas with broadcasting services (difficult due to high power high tower versus medium power medium tower ) Coordination with mobile networks in neighbouring countries also using Digital Dividend mobile, Protection of Aeronautical Mobile Services in Eastern Europe has to be ensured Interference inside Germany (Prevention and measures to resolve interference cases): Protection of DVB-T- reception in MHz has to be safeguarded, resolve interference cases BNetzA coordinates all LTE800 BS s in Germany to protect future DVB-T reception Front end filters for DVB-T receivers may need to be applied in case of interference to suppress mobile signals Electromagnetic compatibility with cable networks using the band MHz: small risk but politically sensitive, prepare for solution of interference cases Wireless Microphones: support coordinated transition to alternative spectrum during LTE800 deployment phase; provide information about LTE800 deployment to microphone users (via BNetzA)

11 Cross border coordination One critical success factor European harmonisation is essential Currently a certain corridor along borderlines can t be covered sufficiently with LTE800 w/o violating the thresholds defined for the protection of broadcasting in the neighbouring country. A lot of sites can t be put in operation since bilateral negotiations between BNetzA and foreign NRA s are still ongoing. European wide migration of broadcasting services below 790 MHz at the latest until 2013 is a key factor for being successful in closing the digital divide also in border areas. 11
