Andrew Dornan. "Services Monitor: Broadband Bottleneck,"
Data Communications Magazine, October 21, 1999
This article discusses how European countries are far ahead of most countries
when it comes to mobile communications technology, but how they are lagging
behind when it comes to implementing fixed wireless communications systems.
Wireless implementation in the United States, for instance, allows some cities
to enjoy network speeds of forty five million bits per second (45 Mbps), which
is the equivalent of what is known as a "T3". Part of the problem
seems to stem from the fact that most European governments have yet to allocate
parts of the radio spectrum dealing with wireless frequencies. This means that,
like the FCC in the U.S., the governing bodies of Europe would have to decide
which frequencies would be used for wireless network transmissions, so as not to
interfere with other systems using frequencies in the same part of the
transmission spectrum. Another discussion about hesitation to implement wireless
technology appears to revolve around the fact that the Europeans don’t want to
interfere with use of the broadband satellite systems already in place. Finally,
this article discusses the impact on vendors, due to the lack of a standard for
wireless, which will cause them to manufacture equipment which may or may not be
compatible with anyone else’s equipment.
A few issues come to mind through this article. One issue, which seems rather
important, is that not only in Europe, but also in the U.S., certain parts of
the frequency spectrum pertaining to wireless communications are still
unallocated by the FCC. This means that a number of different communications
technologies are competing for the same frequency ranges. For instance, wireless
networks typically use frequencies around 2.4 GHz. This is the same frequency
used by certain wireless telephone systems. Also, the notion about lack of
industry standardization comes to mind. One only has to look back at the same
thing (lack of a standard) which happened to the modem industry not too long
ago. When the 56 Kbps modems became available, they were available in two
different "flavors", which meant that if a user had one type of 56
Kbps modem, it could not communicate properly with the other type.
For
discussion purposes, the following questions would be well suited for helping to
keep in mind some important issues as the development of wireless technology
unfolds:
1. What will be the impact of leaving these frequencies unallocated
to specific technologies?
2. Will there have to be another method for ensuring
that communications meant for a particular device is received only by that
device, and not another?
3. What will be the impact of a lack of standardization in
manufacturing?
4. Will wireless technologies suffer the same effects as the
modems did earlier, or will there be a way to prevent that situation and
allow for quicker and easier compatibility with wireless devices?
