Anatech Electronics Newsletter - May 2013
Anatech Electronics has published its May 2013 newsletter. As always, it includes both company
news and some tidbits about relevant industry events, regulations, and standards. Anatech Electronics'
Sam Benzacar invites you to visit them in booth #2710 at the IMS 2013 trade show in Seattle,
5G: Don’t Hold Your Breath
Samsung says is has demonstrated “5G” wireless operating at 28 GHz, generating gigabit-per-second
data rates over a 2 km span. However, the devil is in the details: they used 64 antenna
elements, which might be the world’s most “massively MIMO” system. Millimeter wavelengths
have huge advantages in bandwidth but huge disadvantages in propagation characteristics.
There’s also no standards body working on a 28 GHz solution as no country has a wireless
allocation there. The demonstration was nonetheless an interesting example of what the future
may bring. At gigabit speeds, wireless would after all be able to compete with wired solutions
like Fiber to the Home, satellite, and traditional cable.
Vendors Face Off
in Radio Competition The Army says it is committed to “full and open competition” as it
begins the selection process for companies that will build (or continue to build) its JTRS
(Joint Tactical Radio System) handheld digital radios. General Dynamics and Rockwell Collins
are the incumbents but others like Harris are also formidable competitors. The Army’s final
contracting arrangement is not yet firm, but if one winner emerges it might have five years
Group Says Wide Guard Bands Not Necessary
A group of broadcasters, wireless carriers, and manufacturers has warned the FCC that
guard bands wider than 12 MHz provide offer no benefit and would decrease the amount of
licensed spectrum available for auction. The group says the best guard band size is 10 to
12 MHz above TV channel 37 and takes into consideration the required “duplex gap” between
wireless transmit and receive channels required for a Frequency Division Duplex (FDD) band
plan. The group says “there is no sound engineering justification for the extremely large
(18 MHz to 28 MHz) gaps proposed by some people…” As for the guard band between mobile downlink
and TV, the group says no more than 10 MHz of separation is needed to avoid blocking the
mobile receiver or causing interference to TV broadcast services.
DAS Forum Now HetNet Forum
In an effort to remove the continuing
confusion about how to define itself in the evolving world of distributed antenna system
(DAS,) Wi-Fi, and small cells, the DAS Forum has decided that the most inclusive name for
its organization is the Heterogeneous Network (HetNet) Forum. As the PCIA noted: “HetNet
Forum members are using every tool in their toolbox to deliver wireless broadband to consumers
everywhere—indoors and outdoors, urban and rural.”
A Message from Sam Benzacar
A Time for Reflection
By Sam Benzacar
As a good portion of
the RF and microwave industry gets ready to make its annual trek to IMS, it’s a great time
to take stock of where we are since last year’s show – other than older and wiser of course.
The big topic right now in wireless is the almost certain upsurge in small cell deployment
(including backhaul) in all of its variants thanks to the need to ensure high data rates
“everywhere”. This has been predicted for years but is now actually happening and the potential
for the industry is immense.
And no we don’t have a defense budget so there’s
no way to predict exactly what programs will be killed, pushed out, or reduced in scope.
As usual, when all of this shakes out there will be winners and losers depending on what
programs each company is serving. Regardless, defense procurement is not going to disappear
and RF and microwave hardware remains one of the key drivers for communications, radar,
EW, avionics, ballistic missile defense…and a lot more.
As a filter manufacturer,
I see plenty of opportunities for several reasons. First, interference is getting worse,
not better, a trend that will certainly continue as guard bands shrink and new services
(and new types of equipment) appear. In the case of distributed antenna systems (including
small cells, Wi-Fi hot spots, et al) interference is a potentially enormous issue – and
filters as always are a big part of the answer. Filter manufacturers will be pressed to
deliver higher levels of rejection, lower levels of PIM, and greater overall performance
than ever before.
Fortunately, Anatech Electronics is up to the challenge. We’re
increasingly called on to create bandpass filters, duplexers, and multi-function products
such as multiband multiplexers that approach the limit of what physics will allow. It’s
not easy, but with more than two decades of experience in filter design and manufacturing,
