    Geoff Huston on Wired vs. Wireless #broadband 

    Geoff HustonGeoff Huston’s latest Internet Society ISP Column examines the Australian scenario where, in the recent election, the vying parties plumped down on either side of the wired vs wireless question. He concludes that, just like the election, there is no outright winner.

    He notes the reality that while wireless IP service often actually costs less to provide, users are prepared to pay more for it, giving providers little incentive to invest in wire. But wireless bandwidth scalability is, ultimately, limited. What’s more its inherent unreliability is TCP hostile. However ubiquitous wireless service would be a lot cheaper to implement: $6B (AUS) vs $43B (AUS) for wired.

    He then gets to the big question, which all countries including the USA are having to address, namely how much of the taxpayer’s money is worth expending, and to what effect:

    Where should public funds be spent? On a comprehensive revamp of the wired access network, replacing the aged copper pair telephone network with a highly capable fibre optic network? Or on improving access in those areas where the copper pair network simply cannot support high speed access by public investment in wireless infrastructure?

    In trying to answer this question, we return to a persistent theme in the area of public communications infrastructure. What’s the role of public capital investment and how is that balanced against the role of private capital investment? Is it possible for private investment to fulfill the entirety of a public agenda? Given that a capable, cost efficient and effective public communications infrastructure that encompasses an entire national constituency is seen as a core deliverable of any national communications policy regime, then how is this best achieved today?

    To move back from generalities to the specifics of this broadband investment choice, is it realistic to expect that we have further decades of useful life from an already ageing copper pair infrastructure? As a consequence, should current public investment focus on current gaps in the national infrastructure, using a relatively cost effective approach of plugging these gaps using wireless infrastructure where the copper network is simply inadequate, and leave the remainder of the network in situ, as being adequate for the moment Or should we leave such wireless infrastructure investment to private enterprise, given that this technology is enjoying strong consumer attention and there is a continuing investment in wireless infrastructure by the industry actors. Instead, should a public investment program focus on a longer term national program of replacing the copper loop with a comprehensive fibre optic network? From such a longer term perspective perhaps the NBN is the better approach, as we need to concede that the level of investment required for a national very high speed access infrastructure in a fibre access network is probably well beyond the scope of private capital works investment. So far all that the industry has achieved in this space has been the rewiring of the CBDs in the major cities, while the upgrading of remainder of the network has been effectively ignored. It appears that this is, like many major infrastructure projects in the past, one that properly sits in the realm of a public investment program, in the same way that we’ve made investments in national road, rail and shipping infrastructure in the past.

    ISOC ISP Column: #IPv6 penetration reaches 5% 

    In the April 2010 edition of Geoff Huston’s ISOC ISP Column he reports that the extent of full end-to-end IPv6 capability in today’s Internet is now at a level of 5% of all end systems. This number is now at a level where IPv6 deployment is now passing from mere statistical interest to mainstream commercial importance.
