The digital and print versions talk about the trends going on right now -- lack of expertise, reticence of the ‘millennium generation’ to study subjects and gain skills that manufacturers need, and how all sorts of devices are coming onto the plant floor and carpeted areas to help workers do their jobs more efficiently.

Nine tips help enable an industrial wireless mobile workforce, including standards, self-healing technologies, and the right blend of hardware and software.
The latest copy of Control Engineering has some useful Tips and Tricks that point towards the kinds of solutions and offerings Cisco provides, to make our customer’s lives easier. In a later post I’ll elucidate on the tips and explain how Cisco is able to make for a Smarter Wireless Industrial Workforce. For now, here are the tips:
#1) Standards-based solutions: Ensure suppliers provide open standards based solutions—this is particularly important when choosing wireless mobility systems.
#2) Self-healing wireless: System integrators can provide good interference detection and mitigation wireless solutions that can automatically change channels to maintain continuity, which reduces operating expenses.
#3) Hardware vs. software: It is better to use wireless systems with specialized hardware and software implementation rather than the older software implementations when analyzing interference. Read More »
I was driving home the other day when I heard a radio report on densely populated California cities. What’s interesting was a mention of a small California city that is ranked as the nation’s fourth most dense urbanized area. I guess that a lot of people don’t know Delano, a central valley city with a population density of 5,483 people per square mile. It’s surprisingly more dense than the New York-Newark, N.J. metropolitan area which is ranked the 5th.
Many people with many devices in a densely populated area can pose a challenge to WiFi networks. I was talking to a Cisco customer in the New York City area a few days ago. He said that deploying WiFi was not as straightforward as it used to be. There are many RF interferences near his office and many new SSIDs that he never saw before.
We often talk about business issues, customer care-abouts, productivity savings and the like on this channel, and sometimes philanthropy or esoterics, but mostly if you’re an engineer you have to deal with the technology, the installation, the support, and all the other stuff in terms of where the-rubber-hits-the-road.
When we post videos, we know people lose interest if they’re more than five minutes, so I’m glad it takes less than that to connect the gear up. A couple of cheats help of course -- like switching the radios on in the Cisco gear (they are shipped switched off for security reasons), and it helps to have a pre-charged battery available for the Intermec CK3. But then the video wouldn’t have made it onto the channel! We have quite a few customers with this kind of Warehouse technology.
Ok, so maybe you are starting to give in to the idea that, employees bringing personally owned tablets at work, is indeed not a fad and you have to deal with it. You have decided on a BYOD strategy that protects company and network resources, while (mostly?) satisfying user appetite for connectivity anywhere from any device.
Great! Now. Is your 802.11n wireless network capable of delivering the user experience that is associated with these new sleek gadgets?
If you thought your network is “good enough”, then think again. This client wave is about to disrupt everything in multiple ways.
First, more devices on the network translate to significantly higher demands for bandwidth. In many cases bandwidth requirements can grow exponentially because the ratio of user to devices is no longer 1:1 but 1:2 and often 1:3. We therefore expect to see network utilization significantly rise over time.
Second, tablet form factor now allows users to truly be mobile. Unlike laptops, users can now walk/move and be productive at the same time. This new type of behavior will increase the number of clients roaming between access points.
Finally, it has been observed that tablets are primarily used for content consumption (as opposed to creation), and video is one of the predominant types of content being consumed, which further complicates bandwidth issues, but also creates new challenges.
