What’s Next For Wi-Fi?
Wi-Fi is that short range wireless LAN technology that practically everyone uses. Also known by its IEEE standard designation 802.11, it has achieved ubiquitous status since virtually all laptops incorporate it and there are few, if any, enterprise LANs that do not support multiple access points. But in all its glory, Wi-Fi is nearing that state of being taken for granted.

Amateur Radio Still Going Strong
The Dayton Hamvention is one of the longest running continuous amateur radio conferences in the world. This year was the 56^th installment of the event and it was held in its usual place, the Hara Arena in Dayton, Ohio, May 16-18. I haven't been to the event since I worked for Heathkit back in the late 1970s and early 80s. With a major article on amateur radio and the latest equipment facing me, I thought I had better take a look to see what is going on in this amazing hobby.

Wireless System Design Update for May 2008
The wireless industry, especially the cell phone sector, changes so fast that if you donâ€™t continuously monitor changes, you will invariably be left in the dust. Conferences are a great way to stay abreast, but the effectiveness varies from gala to gala.

The Bigger The Better? Or Do Good Conferences Come In Small Packages?
The wireless industry, especially the cell phone sector, changes so fast that if you don’t continuously monitor changes, you will invariably be left in the dust. Conferences are a great way to stay abreast, but the effectiveness varies from gala to gala.

Wireless System Design Update For April 2008
In case you haven't noticed, we live in a cell phone-centric world. Steve Largent, president and CEO of the CTIA said at one of the keynotes during the recent CTIA conference, "We are living through our cell phones." At first I was skeptical of such a statement, but thinking about it, he's right. The cell phone may just be our one single most important accessory or appliance—however you want to classify it.

Wireless System Design Update For March 2008
Each week I hear more about products and plans for the unlicensed 60 GHz spectrum. Yes, that is 60 gigaHertz, or 60 billion cycles per second. Very high frequency indeed. What can you do with frequencies that high? Well, with all the progress in 60 GHz semiconductors, we are about to find out. A 60 GHz wireless product is probably in the near future.

Wireless System Update For February 2008
I have always been amazed by how much difference a good antenna makes in a wireless application. It became pretty clear to me at an early age as a ham radio operator that a good antenna is the difference between making a connection or not. But now, having stated the obvious let me say that designing a new antenna is just as much art as it is a science.

Antennas: The Black Art Of Wireless
The theory is well known and the design/simulation software is better than ever, but antenna design seems to thrive on intuition, a bit of art and some believe actual magic, and lots of experimentation.

FCC Meeting Goals For Spectrum Auction
As you may have heard, the FCC started auctioning off 62 MHz of prime spectrum space in the 700 MHz region January 24th. This is the spectrum being abandoned by the UHF TV stations as they switch from analog to digital format on February 17, 2009. This is excellent spectrum space as it supports longer range and greater penetration than the higher cellular and microwave frequencies.

Wireless System Update For January 2008
There are literally dozens of methods used in transmitting data wirelessly over short distances. Here is a look at what is happening with some of the more commonly used standards like Wi-Fi, Bluetooth, UWB, and ZigBee.

Competition For A Wireless Video Home Heats Up
As short range wireless technologies have gotten speedier over the years, most companies have been seeking ways for their technology to gain a foothold in the high volume consumer electronics market to transmit video over short distances to eliminate the gaggle of cables we’ve gotten used to.

Wireless System Design Update For December
There are a couple of subjects I never got around to this year in WSD, specifically the Google cell phone possibilities and femto cell's potential. None of this exists at the moment except for some trials here and there, but you will be hearing more about them in the coming year. Here is a look at what to expect.

Wireless System Design Update For November
Have you become dependent on your cell phone? Do you feel naked without it? Has your cell phone become a source of entertainment as well as just a way to make a phone call? Most of you would say yes to all those questions. Which is why the cell phone business has grown so big and continues to get bigger...

Wireless System Design Update For October
It was 50 years ago October 4th that the first successful satellite was put into orbit. Launched by the Russians, this satellite called Sputnik, as basic as it was, set off a stream of events that could not have been anticipated. Besides starting the space race, launching the satellite industry, revolutionizing the telecommunications business, and intensifying the cold war, this satellite had so many unintended consequences, good and bad, it is hard to identify all of them...
