Hi Gary,

Given the number of options and the breadth of the wireless field, I wouldn't want to leave you with a one thought answer. It would be useless. At the same time, I am not the wireless expert here, as others surely are.

Some general perceptions I have, however, lead me to consider that wireless may start to enjoy a much better future penetration rate than it has seen thus far. Indeed, most markets don't even have a wireless last mile contender yet.

As far as I'm concerned, up to this point it has simply been an incubator tech in those niches that are going to make the difference for 'net access, say, and it is only now beginning to form some wings.

With the next steps up in throughput handling capabilities, IMO, we'll begin to see wireless make an appreciable dent in the last mile stats going forward, for a number of reasons. Chiefly, when deployment commences in earnest, it will be a lot less expensive getting it out there without having to pass homes on the basis of maybe they will, maybe they wont, cost exposure like cable upgrades do.

Large areas (radii measured in the tens of miles, sometimes approaching the century mark) could be covered, for example, without operators having to lay down cash on street construction costs, pulling, field electronics, etc. It also enjoys speed-to-market advantages which could be used to catch competitors entirely off guard, relatively, in terms that could possibly make a difference, not allowing them adequate time to respond when they come under wireless threats.

If they can present their services at comparable costs, i.e., using the 30 to 40 price points we're seeing for cable as a reference, supporting minimum realized throughputs of 256 to 512 kb/s, say, I think that they will acquire support in the way of a viable following. Such realized speeds in the future could actually be better than competing alternatives whose stated potential speeds are much, much higher.

Having said that, I don't for a second believe that many, if not most, forms of wireless delivery will enjoy a freedom from the kinds of dynamics that will stifle their competitors in this sense. It will depend on the amounts of spectrum that have at their disposals, the methods they use to allocate resources, reuse frequencies, etc., and how they design their overall platforms and their entire approach to network architecture.

If one bets on the idea that HFC will not againupgrade anytime soon, we may start to see some reduced levels - even dismal - performance over cable modem lines at some point, which would provide additional impetus to start looking at the lower stated speeds of DSL and wireless, which may not, after all, look that bad in real-world comparative terms, at that point.

Then again, the cable cos could take the unlikely step of accellerating their secondary (triage for the first) upgrades, or resegmentations. But these are highly unlikely to take place anytime soon (indeed there are still large serving areas that haven't even seen their first upgrades, yet) to the extent that they would yield sufficient improvements, unless the black cable portion were replaced altogether, IMHO. And we are not about to see that take place for a number of technical reasons, not the least of which is because the DOCSIS line port looks for coax.

Stated another way, DOCSIS, one of the most truly beneficial ideas the cable folks have had in order to streamline procurement and standards compliance issues, has a top end that was designed to operate over coax, defeating any possibility that it could be easily leveraged in a future optical domain.

Actually, the shortcomings would go far beyond the front end where the coax meets the box, but we'll leave it at that for now. This obstacle notwithstanding, there are plenty of other reasons which center on financial justifications and risk which would be more influential at this point, in standing in the way of going purely optical to the appliance. Someone else will have to come out with that model, the cable cos wont. Not any time soon.

I think that Bernard and wireless wonk, along with several others here, may want to add to this. Surely, others will want to disagree.

Regards, Frank Coluccio

ps - I have not explored WLGS to any meaningful extent

Gary:

I don't have much to add to Frank's commentary; I think he has a handle on the space far better then his modesty allows (g).

From 50,000 feet a couple of thoughts, all IMHO:

In the near term last mile connectivity will be provided by a mosaic of technologies - deployed where either there is an absolute cost advantage or where there is a strategic imperative which trumps the cost factor. Consequently, I have no doubt that cable modems, xDSL, fiber, wireless and satellites will all have success.

Focusing just on terrestrial wireless, one has to distinguish first between mobile and fixed. Mobile wireless (cellular, PCS) is developing 3rd generation technology which is promising burst rates up to 5 mb/sec. Due to the placement of the cellular and PCS bands on the frequency spectrum, the opportunity exists for ubiquitous coverage, i.e., anyone/anywhere can get it. However, I don't believe it will become a viable last mile contender in all but the most rural locations because the cost per bit will always be too high due to the small frequency allocations per company at these frequencies and because transmission efficiency (commonly expressed in bits/hertz) is low due to the mobility requirement.

That leaves the fixed environment. Generally, the proponents of wireless last mile connectivity are using spectrum above 2 Ghz. MMDS at 2.5 Ghz, recently in the news with the MCIWorldcom and Sprint acquisitions, is the frequency being used by WLGS. The most prominent broadband wireless companies, Teligent, Nextlink, and Winstar are or will be using spectrum in the 24, 28 and 38 Ghz bands. Service at these frequencies is limited by line-of- sight (LOS) considerations, i.e., if one cannot see the transmitting tower from the receive location, you probably cannot get service. (For example, trees block the signal quite effectively ) Consequently, the aforementioned companies are primarily focused on provding service to business - where the monthly recurring revenues are higher and hence the engineering cost associated with insuring an adequate signal can be predictively recovered.

Last mile - broadband - connectivity to residences is a tough nut because of the LOS issue. I've read many a PR which implied service availability for consumers - but it still will be a hit or miss proposition.

One last note on WLGS. While there is adequate spectrum for broadband wireless in the MMDS band, it is not allocated in a contiguous block to any one company. Notwithstanding that there is 200 MHz available, it is subdivided into blocks of various sizes - most commonly 4, 6 MHz channels - as well as being divided between commercial and non-commercial (most educational) interests. Consequently, acquiring sufficient spectrum in any particular city to provide a robust, high speed service capable of delivering a minimum of 256-512 kbps (using Frank's number) to a sufficient number of subscribers to reach operating breakeven has to be looked at on a case by case basis. I have not looked at WLGS' spectrum holdings so I cannot comment further. For information of the structure of the MMDS spectrum allocation a lot of good technical and historical background information can be found here #Subject-9526
