Adults Love Texting But…
About 83% of American adults
own cell phones and 73% use text messaging, according to The Pew Research Center's Internet & American Life
Project. The survey found that adult text messaging users average 41.5 messages a day with the median of 10
texts and 12 calls a day. People who use text messaging said they prefer it to voice calls but 53% overall
said they preferred a voice call over a text message. People ages 18 to 24 exchange an average of 109.5
messages on a normal day (!) or more than 3,200 texts per month with a median of 50 messages per day or 1,500
messages per month.
802.11n-Enabled Wi-Fi Equipment Up 17% in
Global revenue for the 802.11n WiFi equipment market remained flat compared to the
previous quarter according to In-Stat, with TP-LINK first with 26% market share, NETGEAR overtaking D-Link as
second with 19% market share, and D-Link holding steady with 17%. Shipments of wireless network adapters were
up 7.4% to 5.27 million with North American market share rising to 33%. 802.11n-enabled networking equipment
now accounts for 68% of all Wi-Fi networking equipment unit shipments, according to
RF Safety in SFO
The San Francisco Board of Supervisors has passed a new ordinance requiring mobile phone retailers to display
and distribute a state-produced fact sheet that explains RF emissions from cell phones and how consumers can
minimize their exposure. The ordinance amends the city's controversial Cell Phone Right to Know Act, a similar
law passed last year that required cell phone retailers to post and distribute radiation information for every
make and model of cell phone they sell.
Microwave Energy to Fight Malaria?
Penn State College of Medicine has received a grant from the Grand Challenges Explorations initiative created
by the Bill & Melinda Gates Foundation to continue to pursue a global health research project called “Use of
Microwave Frequency as Treatment for Malaria.” The research will explore the effectiveness of low power
microwave energy for treatment of malaria in mice. Malaria, once inside the red cells, accumulates iron in its
food vacuole and researchers believe this iron may be targeted by microwave energy. If so, the study could
yield a new strategy for the treatment of the disease.
A Message from
Defending Defense Communications
Considering the importance of military communications systems to our nation's security, you would think
they should take priority over commercial interests when it comes to the use of spectrum. However, that simply
isn't the case. The Department of Defense and security agencies have to fight it out along with everyone else
to retain their allocations in the crowded spectrum below about 6 GHz. As a result, the military annually
commits enormous resources to ensuring that communications can be conducted unimpeded throughout the country.
Even with these efforts, interference remains a significant problem for defense agencies and one that gets
worse every year as new commercial wireless networks are deployed along with those of other services. For
example, while macro cell deployment may have “topped out”, tens of thousands of distributed antenna systems
are popping up on utility poles, water towers, and other suitable structures in order to eliminate coverage
gaps. Even though these sites are spectrally “clean”, they still add to spectral density.
proliferation of wireless services poses the greatest threat to existing military systems that have operated
for years without problems but now face new interferers. Every year, the application engineers at Anatech
Electronics receive requests to mitigate such problems, and we typically remedy them with high-performance
cavity filters that attenuate interfering signals to tolerable levels.
If you’re involved with the
design or maintenance of these systems, please contact us. We’ve solved extremely complex interference
problems with cost-effective solutions tailored to the needs of each one. Call us today at (973) 772-4242, or

A MILCOM Reminder…
If a picture is worth a thousand words, then our live product
demonstrations at this year’s MILCOM exhibition (Baltimore Convention Center, November 7 to 10) ought to be
worth even more if you’re trying to tackle interference issues. We’ll be showing attendees how RF and
microwave filters eliminate complex interference problems in both new designs and existing installations.
Members of our engineering staff will be there and ready to answer even the toughest questions. So put us to
the test by stopping by Booth 800!
Some Final Words About Steve Jobs
By now, everyone who ever knew, met, or had anything even remotely to
do with Steve Jobs has paid homage to the man. But left unsaid is Jobs’ indirect contribution to the
well-being of the RF and microwave industry. Steve Jobs was not an RF guy, nor was he an engineer. To Jobs,
microwave and most other technologies were simply a means to an end, which was enabling people to do things
using his ideas that when translated into products made them better than those of the competition. The most
important of those from an RF and microwave industry perspective is the iPhone. Like most every product
category he focused on since rejoining Apple, the iPhone changed the face of the smartphone forever. Like the
MP3 player that Apple reinvented, the iPhone wasn’t the first smartphone but rather one that lived up to its
name, which no company had been able to do until Jobs and his crack design team showed them the way. This feat
spearheaded the proliferation of smartphones, which has benefitted the RF and microwave semiconductor industry
enormously as smartphone manufacturers consume huge numbers of devices ranging from small-signal and RF and
microwave power transistors and MMICs to SAW filters. While you may not be a fan of Jobs’
“our-way-or-the-highway” corporate philosophy, he was unquestionably instrumental in sustaining the RF and
microwave industry even during times of economic crisis.
