An alternative "anti-competitive" solution is proposed to address the problems of spectrum and format fragmentation in the wireless industry. Drawing parallels to the centralized planning of electric power grids, the proposal suggests governments standardize cellular frequencies and formats in each country to create a single, coordinated national wireless network. This could maximize coverage, performance and reduce costs by avoiding duplication of infrastructure, in a similar manner to how centralized electric utilities operate more efficiently through economies of scale. However, such an approach may be opposed on grounds of reducing competition. The role of some regulatory planning is discussed as the wireless sector matures from a luxury to an essential service.

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

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

28. Software Defined Radio is a noble goal – especially for narrow band base stations with sufficient design and cost margins
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

47. The history of regional regulation and competition have led to today’s often highly fragmented market which has many inherent inefficiencies

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!”
