What About BPL Pollution?

Broadband communications represents a potentially high-growth market 
for years to come. The infrastructure solutions for broadband 
services are many, including wireless access and fiber optics, with 
no clear winners. One of the more intriguing competing technologies, 
broadband powerline (BPL) communications, takes advantage of the 
existing powerline infrastructure to send high-speed data from point 
to point and into subscribers' homes. 

On the surface, it appears to be an almost ideal solution, provided 
that BPL can deliver the data rates needed for true broadband 
communications services. But there is concern, especially among 
users of the HP and VHF spectra, including amateur radio 
aficionados, from BPL radio pollution. Although not resolved, the 
Federal Communications Commission (FCC) has noted in its adoption of 
BPL rules last year that BPL is a source of interference for 
existing HF and VHF operators. If you have concerns, please share 
your thoughts by contacting me at: mailto:[email protected]

Rogers To Unveil New Material at MTT-S

New and improved, thinner RO4350B will be on display at the Rogers 
Corp. (Rogers, CT) booth at the upcoming Microwave Theory and 
Techniques Symposium (MTT-S) next month in Long Beach, CA. Designed 
for high-speed digital and test applications, the new material 
features dielectric loss of only 0.004, good plated through-hole 
reliability, and consistent dielectric constant at various data

Active Models Support Nonlinear Simulation

Computer-aided-engineering (CAE) model developers Modelithics have 
created a new nonlinear transistor library to complement their 
library of capacitor, inductor, and resistor models. The new 
library, which is now available for use with the Advanced Design 
System (ADS) suite of CAE tools from Agilent Technologies (Santa 
Rosa, CA), includes small-signal models for low-noise amplifiers 
(LNAs) as well as LDMOS power transistor models for high-power 
amplifiers (HPAs). The library contains models for a wide variety of 
industry-leading BJT, JFET, MOSFET, MESFET, and pHEMT transistors 
from major vendors, including: Cree, Agilent, Excelics, Infineon, ON 
Semi, Mitsubishi, Motorola, NEC, Philips, and Rohm, with more to be 
added continuously.

Salerno University Upgrades Antenna Test Lab

MI Technologies (Suwannee, GA) announced that is has been selected 
by the University of Salerno (Fisciano, Italy) to supply and 
commission a state-of-the-art antenna measurement, acquisition, and 
analysis system for an existing anechoic chamber located on the 
University campus. Under terms of the contract, MI Technologies will 
install a cylindrical near-field test facility that will feature the 
MI-3000 Acquisition and Analysis Software. The system will be used 
to validate existing transform algorithms for optimizing the amount 
of time taken to acquire near-field data using spiral techniques. 
According to Dr. Carlo Rizzo, European Operations Manager for MI 
Technologies, "We have just recently signed a formal agreement with 
the Department of Electronics, University of Salerno, which will 
allow us to share new algorithms intended to drastically reduce 
acquisition time for near-field data in all three geometries 
(planar, cylindrical and spherical). The University of Salerno has 
an impeccable track record concerning the development of new 
near-field techniques for antenna measurement applications." MI 
Technologies will install the system and perform the acceptance

Report Puts Bluetooth In Driver's Seat

Bluetooth technology is replacing wire harnesses in automotive 
applications, according to findings from research firm ABI Research 
(Oyster Bay, NY). The company's latest study, "Dedicated Short Range 
Communications (DSRC), notes that many telematics and navigation 
systems over the past year have moved towards using Bluetooth. As 
ABI Research senior analyst Dan Benjamin comments, "The automotive 
industry regards Bluetooth as an acceptable compromise because users 
get their network connectivity, while automakers do not have to deal 
with installing costly cellular radios, or the hassles of managing 
customer accounts or dealing with wireless carriers." But the report 
states that next-generation collision avoidance systems and even 
intelligent traffic systems will make use of DSRC in the form of 
alternative technologies to Bluetooth.

Wireless Access Chips May Save Millions

TrueAdvantage (trademarked) Wireless Access Solutions from Agere 
Systems (Allentown, PA) are networking chips that Agere claims can 
potentially save wireless service providers worldwide up to $300 
million per year in T1/E1, Synchronous Optical Network/Synchronous 
Digital Hierarchy (SONET/SDH), and Ethernet leased line backhaul 
costs. The solutions include APP network processors, a link layer 
processor (LLP), and framing and mapping devices, as well as 
reference designs, software, and hardware development systems. The 
products enable the convergence of 2G, 2.5G, and 3G network 
applications into a single solution by integrating the various 
protocols. Among the first customers, 3G wireless equipment supplier 
NEC has selected the Agere APP500 network processor for its wireless 
access equipment.
