INTO THE BASESTATION OR HANDSET ? ... some links
Now for the real trick
"If ACT can successfully commercialize its products, the effects will be astounding. Operators could theoretically
upgrade their networks with little more than a software-download. Differentiation based on technology selection
would also be a thing of the past - as operators would be able to have advantage of the distinctive benefits of both
GSM/TDMA and CDMA systems. Overall cellular coverage could also be dramatically increased to cover unserved
areas, as a multi-protocol base station would enjoy superior economics in remote areas."

"The road to one of the communications industry's most elusive goals, the software-defined radio, will probably not
be a straight line. As the advent of second- and third-generation cellular networks turns up the heat in the quest for
this crucial piece of technology for wireless handsets and basestations, chip makers are juggling a multitude of
possibilities. Indeed, some say a mix-and-match approach seems more likely than a single, clear-cut solution."

"It is reasonable to forecast that the first soft-radio implementation will occur in the basestation arena, where power
consumption in such extremee high-performance data converters is less of an issue, while handset or other mobile
implementations will lag well behind."

"One way to meet the need for flexibility and performance is to install what he calls "multiprotocol equipment" --
essentially DSP boards with downloadable software that are capable of executing the separate standards evolving
in the United States, Europe and Japan."

"The IP provider has identified the wireless base station as its initial target application because, according to
Ralston, that's where software-reconfigurable radio technologies will first be proven. "We address the needs of the
wireless industry value chain from top to bottom," he adds, "but we start with network operators and service
providers to help define the nature of the problems imposed by today's multiplicity of standards, as well as the
emerging need to support multiple data rates."

"This is especially relevant for wireless basestations, where it offers significant benefits: reducing the cost, size,
complexity, and power consumption of a basestation (perhaps as much as fivefold). More importantly, it can
support a variety of air/modulation schemes and protocols (AMPS, NAMPS, TDMA, CDPD, etc.) simultaneously,
and switching between them whenever required."

"Since base stations are not battery powered and do not require low power regime, it will be an appropriate solution
for multi mode or multi band base stations. [...] Dataquest believes that 3G base stations will pioneer the use of
SDR. The base stations will be able to cope with the more powerful processors because of fewer restrictions on the
power budget [...]"

"One SDR proponent is BellSouth Cellular, which has spent the last few years promoting the technology as a
solution at both the base station and handset."

"Generally, the industry considers SDR a solution at the base station level, not in handsets. 'We're actually doing
the heart of the problem first," Master said. 'If we can do the handset problem, we can then place it in the base
station.' Master said an SDR solution ultimately must be in the handset, and he said the handset market represents
far more volume for the chip technology than base stations."

Excert from the "SDR-Forum Response to the FCC Notice of Inquiry on SDR"
"[...] When multi-band SDR technology is broadly deployed in base stations, infrastructure, and subscriber
equipment, it will enable various means of improving spectrum sharing. SDR user terminals with sufficient
computational resources could indeed monitor blocks of spectrum and locate free spectrum. But we anticipate that
the owners and operators of wireless networks would prefer to have the base stations and infrastructure select the
spectrum and protocol, rather than allowing subscriber equipment to perform this role. This is because
infrastructure equipment will always be more capable than user terminals of handling the technical issues of
locating unused spectrum; prioritizing access, terms, and conditions; negotiating for access; and checking for
hidden transmitters. In addition, leaving spectrum and protocol selection to network operators will also minimize the
power and complexity requirements of portable and mobile equipment.
Second, SDR will enable another class of signal-processing functions that holds great promise for increasing the
number of users that a wireless cell can support: this class includes smart antennas, multi-user detection (MUD),
and interference cancellation. This group of signal-processing improvements will enable base stations to hone in
more specifically on each user's location, permitting beam-forming transmissions that have already been shown to
increase the number of users that a cell can support by at least 300-400%. These signal-processing technologies
have already been thoroughly tested and are nearly market ready. The SDR Forum is working on standardizing this
class of functions so that all user terminals and all base stations will be able to communicate with one another [...]"

Note: The links above might help during a DD on companies working on SDR. It might help to get an idea on what
SDR is all about and how it could influence wireless communication in the near future (e.g. 3G). The links might
also help to evaluate the market conditions for products and companies for yourself. Please be aware, that this post
can't be your source for any trading decision on such companies. It's just a few links concerning technology issues,
so do your own proper and complete DD before investing.
In the case of startup companies, you must be aware that they are especially risky, don't invest money you can't
afford. BTW: Ask yourself, if you are patient enough for investing in technical start up companies, they are normally
not growing with "dotcom speed", they are about technology and product development and the marketing of it (gain
high/lose all or just break even atfer a long hold, everything is possible). Beware of hypesters and bashers, it's
better to not get influenced by anonymous posters to buy or sell.
