Non-Stop Wireless Network at John Muir Health

Previously I have blogged about No SSID Outage and No Client Reauthentication whereby even if your Cisco Wireless Controllers were to fail due to any reason, the clients will NOT experience any downtime due to Stateful Failover functionality to a Standby Controller. What could be better than that? Controllers that never go down!

A picture is worth a thousand words! As you can see the above the WEBGUI on a 5508 series wireless controller shows that, it is running 7.0 code which was an MD release, has been operational for over a thousand days or over three years! Read More »

How A School District Prepares for PARCC and More

CreepyKidIndian Prairie School district, the third largest school district in Illinois, conducted an in-depth investigation to develop an execution plan to adopt Partnership for Assessment and Readiness for College and Careers (PARCC) consortium guidelines and meet the Common Core State Standards head-on. Their execution plan took them beyond the basic requirements of online testing to providing a secure, borderless learning environment for a variety of devices, over wired and wireless.

Not only was this a great opportunity for them to upgrade their network to meet the state and national testing standards, but also to lay the foundation for any future requirements as technological advances are rapidly changing the education landscape.

Requirements: 

  1. Meet the computer-based testing requirements under PARCC
  2. Provide a borderless learning environment through mobile and online learning
  3. A stable infrastructure that can meet the dynamic network demand
  4. Prepare for the growing importance of technology in classrooms, wired and wireless, with trends such as BYOT (Bring Your Own Technology) as well as an increased use of district-owned devices.

Wi-Fi & Taxes: Digging into the 802.11b Penalty

It’s that time of year again in the US – Tax Time!  That time of year where we review the previous year’s bounty, calculate what’s due, and re-evaluate our strategies to see if we can keep more of what we worked for.  Things change; rules, the economy, time to retirement, and before you know it you find yourself working through alternatives and making some new decisions.

Anyway, as I was working through the schedules and rule sheets, my mind wandered and I started to think about Wi-Fi and the taxes associated with it.  In my day job, I often play the role of forensic accountant.  Like a tax accountant, I’m always looking for a way to get more or understand why there isn’t more already.  So along those lines, lets talk about a little known tax that you may well be paying needlessly.  I’m talking of course about the dreaded 802.11b Penalty.

Wi-Fi protocols like 802.11b are referenced by standards committees for the workgroup that develops them.  In the 2.4 GHz spectrum, there is 802.11b, 802.11g, and 802.11n.  Back in 1997, 802.11b  was the first modern Wi-Fi protocol ratified by the IEEE and it allowed transmissions of 11 Mbps, a major jump forward from the previous 2 Mbps  that was possible with the original 802.11 standard.

After 802.11b came 802.11a, and then 802.11g.  Both of these protocols where a radical departure from the simplistic 802.11b structure and employed Orthogonal frequency-division multiplexing (OFDM) modulation (now standard in every 802.11 protocol created since then).  OFDM allowed for Read More »

Location, location, location…!!!

A very clear trend visible here is how location had become a key part of the digital marketing language.

It was part of the Keynote addresses.

  • Facebook’s former Director of Marketing is advocating it.
  • Google are presenting on it and delivering workshops on it.
  • Various booths talk about its importance.
  • Numerous speakers mention it in their presentation.
  • And Cisco are evangelizing how indoor location using WiFi and CMX can really enhance location capabilities and hugely driven additional revenue streams and enable new business models. Read More »

Small Cells Are Big For Business

Closing the big deal.  Calming an irate customer.  Clarifying instructions given in an email.  Voice has long been the killer app for business.  As the world goes mobile, smartphones are becoming a key way for business people to stay connected, not just when they are out of the office, but an important means of voice communication in the office.  Like consumers, many business users are cutting the cord and using their mobile device, instead of their desk phone, to make and receive voice calls.  A recent Cisco study of mobile users reveals that 50 percent of knowledge workers use their mobile phone at least one-quarter of the time to make calls in the office, instead of reaching for a desk phone.  And, 35 percent of knowledge workers equally choose between a mobile and desk device when placing a call.  We expect this mobile displacement of the traditional desk phone to grow as employees increasingly bring their own mobile devices to work and use them for conducting business.

Mobile cellular networks were built to cover large outdoor and semi-outdoor areas.  They were never built to penetrate the steel, glass and concrete of modern buildings.  While there may be some coverage near the windows, the signal strength rapidly degrades as you head towards the center of the building.  This is only going to get worse as new building materials, such as blast resistant glass, make it even harder for signals from the macrocell network to adequately cover the place of work.  Our research found that one-third of all business users receive only 1 to 3 bars of signal strength at their place of work.  And, 10 percent of business people obtain very poor quality mobile service (1 to 2 bars).

The shift to mobile in the workplace should be Read More »
