Using Tadiran Li Batteries. Our required battery lig=fe is greater than 10 years. We are currently acheiving that life on a cell phone based data system.
@pauln, @apdobaj - the one I use is simply called WiFi Analyzer by Kevin Yuan, it is available on the google play site for free. I find it very useful for debugging friends wifi issues.
Firstheck the microwave seal - there are some monitors that provide this information to determine if it is still good or not.
If it is then proceed below. 1) if you have an android or ios device - use one of their WiFi analyzers to see where your microwave oven is transmitting (microwave has to be on)
2) if it is transmitting on the lower or upper channels, you can simply go in to the router/access point configuration and change the channel to one that is not impacted. This usually can fix the problem.
3) if you can't do that, you can check to see if your wifi devices support the 5GHz range and change the router/access point to use that band.
Budget is like listing all you expenses and incomes(gains and losses). Margin is the line in your budget were you say how much cash you will keep on hand( how much more signal than the minimum)
You say that 802.11 signals effectively raise noise floor for a 802.15 system. Do you know of any studies or references on this that quantify this effect? Thanks.
I believe that receiving in these systems involves a lot of digital signal processing, which might be where the power goes. But again, I'm just a software guy...
Today's first audience question is For those of you who are working with battery powered applications, what battery types are you using and how long of a service life does your application require?
I have tried both Windows Explorer and Mozilla Firefox, also updated Adobe Flash, and still not audio. Looks like they need some good IT engineering to review this audio reliability situation.

The IEEE 802.15.4f-2012 and 802.15.4g-2012 standard documents are currently $5.00 but should also be available soon at no charge since they were both published in April 2012.
The streaming audio player will appear on this web page when the show starts at 2pm eastern today. Note however that some companies block live audio streams. If when the show starts you don't hear any audio, try refreshing your browser.
Andrew Morris designed a circuit that could detect a stroke victim's groan and convert the sound into a signal so caregivers would know when help was needed.
New disc magnet motors fit into the design trend of stepping up to closed loop performance while maintaining the cost advantage of stepper motor technology.
At the Design News webinar on June 27, learn all about aluminum extrusion: designing the right shape so it costs the least, is simplest to manufacture, and best fits the application's structural requirements.
On April 21, NASA launched a novel project, putting into orbit three satellites that employ an off-the-shelf commercial smartphone as the control system.

A lasting memory from my first job as an engineer in an auto assembly plant is standing on hard concrete at six in the morning, vending-machine coffee clutched in hand, listening to ...
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This radio show will show what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
