Everything is wireless these days, right? Or perhaps it just seems that way. MIMO (multiple-input and multiple-output) radios seem to be the most popular of the bunch. MIMO means that multiple antennas are used for both the transmit and receive ends of the signal in the wireless subsystem. The result, in theory at least, is improved performance, including higher data throughput and range without requiring a higher transmit power or additional bandwidth. Rather, the signal is spread between the antennas. Some people refer to MIMO as smart antenna technology.
I’ve been using a MIMO wireless router for many years for the WiFi in my home office. There’s no question that its performance is superior to single-antenna systems. If you’re designing some sort of system that requires wireless, whether it’s WiFi or some other technology, MIMO should be on your list of considerations, and probably pretty high up on that list.
Once you get the MIMO architecture designed in, you’ll need to test that subsystem. Unfortunately, this has been a fairly significant challenge for designers, even those who are familiar with wireless technology. While it might seem trivial (or maybe it doesn’t), there’s a specific process to follow to test properly.
To help you get from Point A to Point B, we’ve assembled a series of classes in our Digi-Key Continuing Education Center called Testing MIMO Radios. While taking these online classes won’t make you an expert, it’ll get you much further down the road in your wireless development. And you’ll be earning IEEE Professional Development Hours at the same time.
The first Tacoma Narrows Bridge was a Washington State suspension bridge that opened in 1940 and spanned the Tacoma Narrows strait of Puget Sound between Tacoma and the Kitsap Peninsula. It opened to traffic on July 1, 1940, and dramatically collapsed into Puget Sound on November 7, just four months after it opened.
Noting that we now live in an era of “confusion and ill-conceived stuff,” Ammunition design studio founder Robert Brunner, speaking at Gigaom Roadmap, said that by adding connectivity to everything and its mother, we aren't necessarily doing ourselves any favors, with many ‘things’ just fine in their unconnected state.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
