“Anti-Competitive” Measures to Improve the Wireless Industry Moray RumneyLead TechnologistJohn HarmonWireless Business Development Copyright Agilent technologies 2011
Overview ,[object Object]
The current industry approach
An alternative “anti-competitive” solution,[object Object]
But an alien arriving on planet earth and looking at our accumulated  baggage of radio communication formats and frequency bands would think, “Huh?”,[object Object]
LTE FDD Frequency bandsBased on 36.101 va.2.0 Table 5.5-1  Duplex spacing Width Width Gap Uplink Band Downlink Band Frequency Points of note ,[object Object]
The Duplex spacing varies from 30 MHz to 799 MHz
The gap between downlink and uplink varies from 10 MHz to 680 MHz
Narrow duplex spacing and gaps make it hard to design filters to prevent the transmitter spectral regrowth leaking into the receiver (self-blocking)
Bands 13, 14, 20 and 24 are reversed from normal by having the uplink higher in frequency than the downlink
Bands 15 and 16 are defined by ETSI (not 3GPP) for Europe only – these bands combine two nominally TDD bands to create one FDD band,[object Object]
As such, the challenge of separating transmit from receive does not require a duplex filter for the frequency domain but a switch for the time domainFrequency
Future LTE/UTRA Frequency bands The work on defining new frequency bands shows no sign of slowing up. These are the bands currently being considered by 3GPP: ,[object Object]
Band 23 	2000/2020 + 2180/2200 - S band additional terrestrial 	component (ATC) of the mobile satellite systems (MSS)
Band 25 	1850/1915 + 1930/1995 - Extended 1900 band – has	issues with GPS co-existence
Band 26 	814/849 MHz + 859/894 – Extended 850 upper band
Band 27 	806/824 + 851/869 – Extended 850 lower band
Other possibilities identified by the ITU:
3.6-4.2 GHz
450−470 MHz
698−862 MHz
790−862 MHz band (European digital dividend)
4.4-4.99 GHz band,[object Object]

John Harmon - Presentation at Emerging Communications Conference & Awards (eComm 2011)

  • 1.
  • 2. “Anti-Competitive” Measures to Improve the Wireless Industry Moray RumneyLead TechnologistJohn HarmonWireless Business Development Copyright Agilent technologies 2011
  • 3.
  • 5.
  • 6.
  • 7.
  • 8. The Duplex spacing varies from 30 MHz to 799 MHz
  • 9. The gap between downlink and uplink varies from 10 MHz to 680 MHz
  • 10. Narrow duplex spacing and gaps make it hard to design filters to prevent the transmitter spectral regrowth leaking into the receiver (self-blocking)
  • 11. Bands 13, 14, 20 and 24 are reversed from normal by having the uplink higher in frequency than the downlink
  • 12.
  • 13. As such, the challenge of separating transmit from receive does not require a duplex filter for the frequency domain but a switch for the time domainFrequency
  • 14.
  • 15. Band 23 2000/2020 + 2180/2200 - S band additional terrestrial component (ATC) of the mobile satellite systems (MSS)
  • 16. Band 25 1850/1915 + 1930/1995 - Extended 1900 band – has issues with GPS co-existence
  • 17. Band 26 814/849 MHz + 859/894 – Extended 850 upper band
  • 18. Band 27 806/824 + 851/869 – Extended 850 lower band
  • 23. 790−862 MHz band (European digital dividend)
  • 24.
  • 25. The industry solution – do it all? VoIP LTE Multi-band (13?) HSPA+ TD-SCDMA High batteryefficiency High spectralefficiency LTE-Advanced MIMO 1xEV-DO(B) Low cost Interferencecancellation 802.16m Operator’s Radio equirements Wants: Everything When: Now! Greenwireless Bluetooth Multi-Carrier TD-LTE EDGE-Evolution 802.16e Dongle or phone Wi-FI A-GPS MBMS Multi-RAT
  • 26. All options available for no extra cost size or weight! Why we don’t have multi-format motor cars today Weight and padding for sound-proofing and ride User-switchable left/right hand drive for roaming Petrol engine for range Diesel engine for economy Light-weight for fuel economy Solar panels for ecology Electric engine for ecology Supercharger for power 4WD for grip
  • 27.
  • 28. Software Defined Radio is a noble goal – especially for narrow band base stations with sufficient design and cost margins
  • 29. For user devices it is not so simple
  • 30. Has anyone seen a software-defined PA or antenna? What we do have is SDB - software defined baseband.
  • 31. Tuneable antennas are being worked on but are no panacea
  • 32. Multiplex filter design is also a struggle – can’t violate physics
  • 33.
  • 34. Industries that rely on such precious resources - like water and power - need to be carefully planned
  • 35. Consider the history of power in the UK
  • 36. Back in the 1920’s strong “competition” meant great choice:
  • 37. DC or a variety of AC frequencies
  • 38. A variety of voltages
  • 39. A variety of independent unconnected generating companies
  • 40.
  • 41. This required standardization of frequency and voltage: 240V at 50 Hz was chosen.
  • 42. The industry fought back strongly on anti-competitive grounds but were over ruled
  • 43. In the 1950s the government nationalized the generating companies creating the Central Electricity Generating Board
  • 44. This was again strongly opposed but it created huge scale resulting in lower costs and better coordination of generation capability for continuity of supply
  • 45.
  • 46.
  • 47. The history of regional regulation and competition have led to today’s often highly fragmented market which has many inherent inefficiencies
  • 48.
  • 49.
  • 50. Compare this with what happened with 2G in the US – a fragmented competitive mess of five systems which eventually led to just two systems with no interoperability.
  • 51. There was a quote on the White House web site some time ago praising the FCC. It went something like this: “Why can’t all our agencies emulate the FCC and generate money rather than just spend it”.The wireless lifecycle is long, requires heavy capital investment and benefits from mobility. All this requires careful planning. In recent times regulators have taken an increasingly soft touch – this is now backfiring. Competition is needed - once the direction is set.
  • 52.
  • 53. The most ambitious example is Yota in Russia who have formed a consortium with competitors MegaFon, MTS, Rostelecom and VimpelCom to build a single shared LTE network.
  • 54. From an engineering perspective it should be evident that if each country’s wireless assets were pooled the potential scale and benefits could look similar to the impact of the national grid
  • 55. A single regulated operating company could maximize coverage and performance while reducing format and band fragmentation
  • 56. The rest of us could get on with designing optimal hardware and applications just like we do with the national grid!“But they’re communists!”
  • 57.
