    Kirt Blattenberger,


RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while typing up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...

Anatech Electronics Newsletter - March 2013

Anatech Electronics has published its March 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, Washington.

Verizon LTE: Network 2
Verizon, which vacuumed up a lot of AWS spectrum from cable companies for $3.6 billion, is finally about to use the asset, effectively creating another LTE band in addition to its allocation at 700 MHz, potentially doubling its capacity. Beginning in July, the company will begin to equip its network and says it will have 5000 AWS-enabled LTE sites by year's end. This means that forthcoming Verizon LTE devices will have to include this band in addition to its current allocation at 700 MHz. It's good news for subscribers, as it will somewhat lessen traffic load, but 90% of the total will still be at 700 MHz for the time being.
FCC to T-band Users: Time to Pack
The FCC is gearing up to move public safety communications out of the T-band (470 to 512 MHz) that it shares with TV channels 14 through 20 in urban areas so the FCC can auction the spectrum in 2021. Where these licensees will go is unknown but the plan is to have several options available, and the commission (through a recent public notice) is asking industry to supply them along with information about how many and what type of operators will need to be moved, what type of equipment they use, and what spectrum is suitable within the VHF through UHF region (including the new D-Block at 700 MHz).
Wi-Fi Gets Some Room
The FCC used the Consumer Electronics Shows to announce that it will make 195 MHz of new spectrum available in the 5 GHz band in areas with high-volume Wi-Fi traffic. It is the largest block of unlicensed spectrum offered to Wi-Fi since 2003. Best guess is that this will provide a 35% speed increase at airports, convention centers, and conference centers. The 5 GHz band is currently used by federal and non-federal users and it will take considerable work to make the change.


Greetings Kirt,

Interference in 2013: Plenty to Go Around
The FCC has plenty to do in 2013. In public safety communications alone, it must wield it's mighty stick to shepherd through the 25-to-12.5 kHz narrowbanding initiative, keep tabs on the pace and direction of the nationwide public safety broadband administered by FirstNet, and begin the process finding a home for the T-band licenses who must abandon their channels as part of the broadband plan deal – to name a few.
On the commercial side, the cry from wireless carriers for more spectrum is getting even louder (as it cobbles together slices of spectral real estate at various frequencies), Wi-Fi is taking on new responsibilities (which the FCC recently acknowledged by promising it more spectrum), and the plan to use "white spaces" between TV channels is moving forward after clearing some issues concerning interference. These are of course just a few of the commission's activities, but they're formidable, and they all have one thing in common: you guessed it, interference.
Higher-order digital modulation schemes, MIMO, and digital signal processing are already allowing more information to be contained in a given channel bandwidth. But squeezing more services into a finite amount of spectrum requires compromise, and it's usually quality of service that is degraded, often by interference. Sometimes services cause their own interference and other times it comes from those nearby, but filtering out the offending signal or signals is always the answer.
Anatech Electronics has been solving interference issues like these for more than 20 years from HF through millimeter wavelengths, using whatever filter solution is the most appropriate in each case. From large cavity filters to tiny SAW filters, we create solutions with extremely high interference rejection that will keep your signals in-band and others outside.
