Anatech Electronics, a manufacturer of RF and microwave
filters, has published its July newsletter. As always, it includes both company news and some
tidbits about relevant industry happenings. In it, Sam Benzacar discusses, among other topics,
an apparent demise (or near demise) of the Commercial-Off-the-Shelf (COTS) component usage
philosophy that once was a keystone in the Department of Defense's cost containment strategy.
A telling chart illustrates the progressive decrease in COTS parts begin designed into defense
systems. My guess is the same type of trend occurred in the aeronautics and space industries
as well. Pundits and talking heads loved to pooh-pooh the '$200 hammer,' but usually that
hammer was a more guaranteed fit for the mission at hand. Having been in the defense electronics
industry myself at the beginning of the COTS era (mid-1980s), I can attest to how you might
have started with an off-the-shelf item, but by the time it was modified, tested, and officially
qualified for inclusion, the savings were not all that great.
A Word from Sam Benzacar
So Much for COTS
By Sam Benzacar
Those of you who either follow the defense industry or sell products into it surely remember
when Defense Secretary William Perry, as part of the Federal Acquisition Streamlining Act
of 1994, directed the Department of Defense to use commercial off-the-shelf technology whenever
possible. The goal was to reduce procurement cost by using parts that were readily available
from commercial suppliers rather than the custom designs that the RF and microwave industry
have long been famous for. It was an enviable goal, and after all, in many respects devices
used in automotive applications, for example, must meet conditions like those required of
That said, COTS always seemed a bit of a stretch for our industry, since a change to any
specification of a "catalog" product essentially makes it custom. Of course, there are varying
degrees of "COTSness," as changes such as connector type really don't make a product custom
in the strict sense. However, as is usually the case with many RF and microwave components,
a standard product is usually where a customer begins and the end result is something considerably
13 years after Perry made his pronouncement, a report from the U.S. Government Accountability
Office, having analyzed 10 years of data, says the Department of Defense is actually buying
not more, but less, commercial off-the-shelf hardware. The data shows that obligations under
DoD contracts awarded using commercial item procedures declined since fiscal year 2007, but
as a proportion of DOD's total contracting obligations they have remained within a narrow
range from 22 to 16%. When the GAO analyzed spending for fiscal year 2016, DoD spent $47.6
billion in commercial items, a decline of $35.1 billion since fiscal year 2007.
Bill Greenwalt, author of many recent Senate Armed Service Committee's acquisition reforms
and a top defense acquisition policy expert, told Breaking Defense that "The linkage between
higher profits and higher risks and performance that occurs on commercial item contracts was
forgotten to keep as many traditional cost-type programs (with somewhat reduced fees) going
during a budgetary downturn."
Needless to say, RF and microwave components are not the only ones contributing to this
decline, but they are typical of many other types of components that often don't fit neatly
into a COTS scenario. Filters are a classic example, and the story in the filter business
has always been that no two filters have ever been the same and that 200-page filter catalogs
became that large because every order was a new product. That's not likely to change.
Mesh Networking Comes to Bluetooth
Special Interest Group added the last piece of the puzzle this month to the Bluetooth 5.0
standard with the addition of mesh networking capability. As mesh networks are essential for
any standard to be used in IoT, Bluetooth was severely hampered from participating in applications
such as home automation and particularly "smart" lighting. As a result, most lighting manufacturers
chose ZigBee, Wi-Fi, or other short-range standard. The addition of mesh networking effectively
puts Bluetooth 5 makes the standard a major IoT connectivity contender for the first time.
T-Mobile First with NB-IoT Trial
claims to be the first wireless carrier in the country to complete a trial of narrowband IoT
(NB-IoT) LTE, the low-power LTE variant designed for machine-to-machine (M2M) applications,
using a 20-kHz channel. The company also announced a partnership with the City of Las Vegas
to deploy NB-IoT throughout the city. Applications will include early warning of floods, "smart"
lighting, and environmental monitoring using sensors on light poles. They will continuously
monitor temperature, humidity, and environmental gases.
Report: Microwave Module Market to Reach $1.7 Billion in 2022
A report from Engalco Research predicts that free-world demand for RF and microwave modules
will reach $1.7 billion in 2022. Increases in amplifier, oscillator, and integrated microwave
assembly revenue will be driven by EW, radar, and satellite communications systems, according
to the report. Products categories covered in the report include amplifiers, oscillators,
converters, synthesizers, and transceivers.
Verizon No Longer the LTE Speed King: OpenSignal
The latest data from wireless network watcher
OpenSignal shows Verizon Wireless has lost the lead for the moment at least in LTE download
speeds, bested by T-Mobile. This is a major upset, as Verizon has long touted its industry-leading
network speeds. However, the difference between the two carriers was minimal: T-Mobile averaged
16.3 Mb/s and Verizon averaged 15.9 Mb/s. Both blew past Sprint and AT&T, neither of which
made it past 13 Mb/s. However, in 4G network availability, a measure of the time that users
have an LTE signal, Verizon was well ahead with 86%.
