802.11ac Wi-Fi – Don’t Bother Yet

802.11ac Wi-Fi - Don't Bother YetThe new iPads are here! The new iPads are here! There’s no 802.11ac here! But that’s expected. Experienced Apple watchers know that Apple likes to let new radio technologies mature before they integrate them into their new idevices. So that means most enterprises can slow their plans to upgrade their Wi-Fi to the new standard according to Kevin Fitchard at GigaOM.

The new iPads are hereThe latest Apple (AAPL) tablet doesn’t sport the new soon-to-be-completed IEEE 802.11ac standard, even though Apple’s latest generation routers, PCs, and laptops all support it. GigaOM reports Apple is providing is a speed boost to the now thoroughly established 802.11n networking standard in the form of multiple-input multiple-output (MIMO) smart antenna technology. Like many Wi-Fi routers on the market, the iPad Air has dual antennas, allowing it to wend two parallel paths over the unlicensed airwaves. The MIMO implementation will double the speeds at which the iPad can access Wi-Fi networks, according to Apple.

The Wi-Fi Alliance only began certifying commercial 802.11ac devices in June, and even those devices only incorporate partial versions of the full 802.11ac spec. The IEEE isn’t expected to fully complete the standard until 2014. Very few smartphones and tablets have ac embedded as of yet, though the technology is making its way into consumer and enterprise routers and PCs, including Apple’s newest MacBooks and iMacs.

iPad AirBut waiting another year for 802.11ac-enabled iPhones and iPads also means we’ll probably have to wait another year before we see wide-scale adoption of the standard in public hotspots and access points. Unlike in the home, most outdoor and public Wi-Fi connections are made over mobile devices, not PCs.

In an interview with GigaOM, Boingo VP of corporate communications Christian Gunning said it hasn’t turned up 802.11ac in any of its hundreds of thousands of owned and managed hotspots yet, simply because it’s seeing very few devices with ac radios trying to access its network.

higher-powered 802.3at Power over EthernetFierceCIO‘s Paul Mah offers more reasons to delay the roll-out of 802.11ac. The advanced 802.11ac radio is more power-hungry than earlier iterations of Wi-Fi. So it will more likely need the use of the higher-powered 802.3at Power over Ethernet (PoE) to run 802.11ac with all its bells and whistles. It is possible that businesses still on 802.3af PoE (rb- Majority) may well have to incur extra infrastructure costs to deploy 802.11ac today. Mr. Mah contends that it is yet to be seen if improved 802.11ac chipsets will allow firms to stick with legacy PoE. (rb- For a refresher on PoE, check out these posts 802.3af and 802.3at)

Another consideration according to FierceCIO is clients. The handful of business-grade 802.11ac wireless APs on the market today typically support three spatial streams, which allows for a (theoretical) maximum data rate of 1.3Gbps in the 5GHz band. Though this is a significant improvement over 450 Mbps 802.11n, the dearth of 802.11ac client devices renders this a moot point. Some will argue that Apple did incorporate 802.11ac into the new MacBook Air laptops.  However, they did not include it in the new iPads, or the iPhone 5S and iPhone 5C smartphones. And with no smartphones or tablets equipped with 802.11ac capabilities today, this does make deploying it a rather pointless strategy for BYOD.

802.11ac "second wave"Finally, Mr. Mah points out that while 1.3Gbps is a good speed to have, we should keep in mind that 802.11ac does have a theoretical maximum speed of 7 Gbps. A “second wave” of 802.11ac that implements four or more data streams for much faster speeds should be arriving in the second half of 2014. He says current signs are that this second wave of 802.11ac devices might need new processor chips–which means you will have to buy new 802.11ac hardware to benefit.

GigaOM’s Fitchard stresses Apple’s influence when it comes to popularizing new technology, he says the iPhone and the iPad’s reach shouldn’t be underestimated. As an example, new Passpoint-certified phones have been out for more than a year, but it wasn’t until Apple started offering support for Passpoint’s automatic login technology in iOS7 that the wireless industry took notice. It was only after Apple made iOS7 publicly available, that Boingo started Passpoint trials.

rb-

I’m not saying 802.11ac is a bad thing, but enterprises need to ignore the hype cycle and make decisions that are best for them and not the multi-billion dollar networking industry. IMHO 802.11ac is still immature, there are few devices out there that can fully take advantage, the full feature set is not fully implemented in silicon and you finished the upgrade to 802.11n yet?

What to do?

What does your wired network look like? Are you still connecting your AP’s at 100 Mbps? That is a bottleneck with 802.11n.

Do you have enough juice? What is your PoE status? Do you have enough PoE+ ports? Are they being used for just an access port – wasting the extra costs of a PoE port?

Both switches cost money, is there a budget available for these items or is IT going to spend an operational budget to address a structural issue?

Farewell Steve Tour

Farewell Steve Tour MicrosoftThe Bach Seat Steve Ballmer farewell tour continues as rumors swirl about Ford (F) CEO Alan Mulally taking over at Microsoft. Or will Bill Gates returning ala Steve Jobs to save Redmond. Whatever the grand poobah’s at MSFT are thinking. They will probably never find another CEO like Steve.

Here is newly minted CEO Ballmer opening up the company’s 25th Anniversary in September 2000, doing what he calls a “monkey dance” and shouting “give it up for me!” When he finally calms down, barely able to speak between gasps of air, he manages to shout four words: “I ..

More Tech Trouble at School

More Tech Trouble at SchoolIt’s not a good time for tech in schools. The security woes at school are not limited to the iPad debacle at LAUSD. (rb- You can see my coverage here – Updates since the first article – LAUSD started confiscating the iPads and delayed the district-wide roll out one year until 2015.) GigaOM’s Ki Mae Heussner writes that Guilford County Schools in North Carolina has suspended its tablet program with Rupert Murdoch’s News Corp’s Amplify after reports of faulty equipment.

NC school district suspends tablet program

uspended its tablet programThe district reportedly spent $16.4 million ($299 / device + a 2-year subscription at $99 per year) of a $30 million Race to the Top grant to pay for the tablets and content. The device is a 10-inch ASUS (2357) tablet running the Google (GOOG) Jellybean Android operating system. It comes pre-loaded with content and apps curated by Amplify. It enables teachers to distribute content across a class or grade level and control the content on students’ screens.

GigaOM cites the school district’s website, which says they have sent 10% of their 15,000 devices back to Amplify because of broken screens. About 2,000 cases have also been problematic. In one instance, a student returned a defective charger, reporting that overheating caused the plastic to melt. While the district said it expected a few glitches with the rollout, school officials decided to pause the program for safety’s sake. GigaOM claims the pause is a big setback for Amplify, which launched its education-optimized tablet at hipster South by Southwest earlier this year.

NewsCorpSince its launch, skeptics have wondered how schools would respond to the privacy questions and the prospect of doing business with Amplify’s parent company News Corp. (given its phone-hacking scandal). Ms. Heussner speculates that the suspension could give schools more reason for pause when it comes to embracing the new technology.

Asus told GigaOM that out of 500,000 chargers of its kind that they have shipped globally, only the one in Guilford overheated and melted. Justin Hamilton, Amplify’s SVP of corporate communications seems to be blaming the customer. He claimed the broken screen rate in Guilford is higher than in other school districts. “We’re working very closely with the district on this and hope to have things resolved and the program back up and running very soon,” Mr. Hamilton said.

Indiana mobile security fail

circumvented the security on district-issued Apple iPadsIn Indiana, Education Week reports that between 300 and 400 students in the Center Grove school district circumvented the security devices on district-issued Apple (AAPL) iPads within hours of receiving the devices according to a report last week in the Daily Journal.

Apparently, students found ways to reprogram the iPads so they could download games and apps for social media sites, according to the report. Center Grove officials attributed the problem to their security program not being able to handle the 2,000+ devices they distributed.

spread like wildfireKeith Krueger, the CEO for the Consortium for School Networking, said such problems are increasingly common as districts deploy an increasing number of devices. “Kids and adults find ways to hack through things, and it can spread like wildfire,” he said. “It’s frustrating, and it’s a huge challenge for any district.

Data center failures

In addition to the tablet troubles, Data Center Knowledge’s Rich Miller reports several school data center failures. According to DCK, two public school systems suffered data center failures that crippled their IT systems.

data center fire suppression systemIn Oregon, the Beaverton School District experienced several days of disruption after an errant alarm set off its data center fire suppression system. The fire suppression system damaged hard drives and servers. That left Beaverton schools unable to use email or access class lists, student schedules, and online textbooks. “It knocked all of the systems in the data center off-line,” said Steve Langford, chief technology officer. “All of the systems that staff needs to do their jobs.” District IT staff worked over the Labor Day weekend to replace the damaged systems.

In California, the Davis Unified School District started school without key IT services after the district’s servers overheated. DCK reports an air conditioner unit failed, allowing the temperature in the server room to rise to 120 degrees F. “There’s an incredible impact on everyone in the whole organization,” says the district’s Kim Wallace. “Students can’t access computers. Teachers can’t take attendance. Parents can’t email. We can’t email out.” The DCK article said staff were still troubleshooting damaged equipment and lost data.

The best strategy, COSN’s Krueger said, is to combine the best possible security filters and other technical measures with a comprehensive responsible or acceptable use policy that students and families must sign and a commitment to enforcement. “It’s not surprising that a school district would have some breaches,” he said. “The question is how do you leverage it into a teachable moment?”

Who needs the teachable moment? Sure the kids need to understand there are real consequences for their actions but, can the politicians administrators be taught to be serious about IT? Seems to me that most of these failures are management failures. It is probable that these failures could have been reduced with proper project management.

proper project managementIt is my experience that many administrators do not recognize project management professionals. It appears they would stick with the good ole boy network and hire their less qualified friends or the professional BSer’s.

Now about project management? Modern backup system? Disaster Recovery plan?  BCP?

LA Schools iPads Hacked In A Week

– UPDATE 08-28-2014 – Just in time for the start of School reports surface LAUSD is “re-opening” bids for its controversial billion-dollar contract with Apple and Pearson to give all students, teachers, and administrators iPads.

LA iPads Hacked In A WeekThe second-largest school district in the US is spending at least $1 Billion to complete a 1:1 tablet initiative. The Las Angles Unified School District (LAUSD) plans to deploy 650,000 Apple (AAPL) iPads, one for each student in LA county. The project slated to be completed by December 2014, has had problems that may prevent if from reaching that goal.

Las Angles Unified School DistrictThe project includes 500 million dollars for iPads and 500 million dollars for Wi-Fi and related infrastructure. The initiative is funded mostly by voter-approved school construction bonds, which taxpayers typically pay off over 25 years which the LA Times says “has sparked some concerns and legal and logistical hurdles.”  (rb- I first noted the project here)

The project has run into a series of issues. The first issue focused on the 25 year payback period on a $500.00 device. A second issue emerged in September 2013 when the district recognized that it may need to buy Bluetooth keyboards for the iPads. The LA Times estimated a bill of $38 million for the oversight. The LA Times reports that the included software keyboard on the iPad might not satisfy the needs of older students writing term papers.

650,000 Apple iPads,Also, LAUSD has planned to use the iPads for testing based on new Common Core English and math learning standards. The article contends that the iPad’s touch screen could frustrate students and even obscure portions of a test item that would be visible in its entirety on a full screen. (rb- I talked to many school districts about the SBAC keyboard testing issue, who is going to configure Bluetooth on and off? What about power? Does Bluetooth decrease the battery time on the iPad? Do you have enough electrical outlets to plug in 30 iPads? How is your Wi-Fi?)

In late September 2013, the LAUSD iPad project ran into a bigger problem as they deployed the iPads to high school students. According to the LA Times, it took exactly one week for nearly 300 students at Theodore Roosevelt High School to defeat the LAUSD installed device security. Following the news that students were using the hacked tablets for personal use, district officials halted home use of the Apple tablets until further notice.

Common Core English and math learning standards.Students told the LA Times once they had the iPad home they could not do anything with the $678 device. Apparently, the students began to tinker with the security lock on the tablets and soon discovered all they had to do was delete their personal profile information. With the profile deleted, a student was free to surf, tweet like, and stream music.

The new found freedom prompted L.A. Unified School District Police Chief Steven Zipperman to suggest that the district might want to delay the distribution of the devices. The chief said in a memo obtained by the LA Times, I want to prevent a ‘runaway train‘ scenario when we may have the ability to put a hold on the roll-out.

I want to prevent a 'runaway train' scenarioAccording to a March 2013 blog post from Roosevelt HS, LAUSD chose AirWatch as the provider for the mobile device management system. And that when students first get their iPads they will have AirWatch already installed. The district posted an update on their website that indicated they have turned to AirWatch and Apple for better solutions to their iPad problem.

rb-

This really is a story of mismanagement from the top down. A billion-dollar project for consumer devices financed over 25 years – Really? Are the students of LA’s class of 2038 going to have to use the iPad’s from 2013? Where is the refresh program? How are they getting the money to buy 650,000 iPad 9’s in 5 or 6 years?

If the iPads are to be used at home? how is LAUSD addressing the digital divide in LA?

Did the big-wigs consider the equity of using iPads for high-stakes nationwide common core testing? Not only will LA students be compared against each other and the rest of California but also students in 44 other states.  It is my understanding that the current SBAC test is not optimized to display well on small screens. Will the tablet form factor handicap LA students or others across the US using tablets when competing against others using large screens and real keyboards in ergonomically proper positions? Will LAUSD show the test takers how to see the entire question, or how to easily switch between back and forth between screens to review a passage and then write a response.

Call me cynical after working in K-12 and living in the Detroit area, but a public $1 Billion dollar government project seems like a magnet for mismanagement, fraud, waste, and pay-to-play scams. It already seems to be at least $20 million over budget to buy keyboards even at K-12 discounts. Hopefully, the iOS and AirWatch updates are already included in the existing contracts.

While the headline-grabbing hacking story may be resolved in Apple’s iOS7. AFAIK Apple does not let anybody into its BIOS or whatever chip it is on an iPad. That is why students can easily delete the AirWatch agent. LAUSD still has a task on its hands to get all the deployed devices up to iOS 7.

LAUSD is missing 71 iPadsIn more signs of mismanagement, The LA Times reports that LAUSD is missing 71 iPads. They deployed 69 of the missing iPads last year at the Valley Academy of Arts and Science. PadGadget reports that after the fact, the District ramped up its tracking efforts by adding stronger safeguards. Global positioning can now be activated for every tablet. Plus, an electronic inventory system registers who is now responsible for a particular device, and District officials can remotely shut down iPads reported stolen.  Lt. Jose Santome of the school district’s Police Department stated, “We know what’s going out and deployed on every campus.”

Six Steps to Avoid BYOD Pitfalls

Six Steps to Avoid BYOD PitfallsIn a recent article on the Forbes CIO Central blog, Dan Woods interviewed Brian Madocks, CEO of PC Helps, a services firm that provides supplemental help desk services for more than 1.6 million end-users. He has been on the front lines as many of its clients have opened up BYOD.

I want an iPadIn the article, Forbes offers advice on how IT departments can respond to users who show up at work and declare: “I want an iPad.”  The author warns that ignoring the corporate use of personal devices (smartphones, iPad’s and other tablets) leave both end-users and the IT department quite unhappy.

Mr. Madocks says the biggest myth is that allowing personal devices to be used for work-related purposes reduces the support burden. At first, this seems strange. If people use devices they know well, shouldn’t they need less help? Also, if an employee is using an iPhone or iPad, won’t their support questions be handled by AppleCare, Apple’s support arm? Mr. Madocks says no. Consumerization reduces some types of support but generates others. Here’s what happens.

ConsumerizationThe number of calls about how to use the device may go down. People know how to use their phones, get on the Internet, and use Facebook. But the number of calls about how to get their corporate email, calendar, and contacts working on phones or tablets may go up. With Apple (AAPL) iPhones and iPads and the fragmented Google (GOOG) Android versions out there it’s even more complicated. The PC Helps CEO reports that users can be frustrated when they go to Apple’s Genius Bar, AppleCare, or to Google for Andriod support and find out that they won’t get any help there because the staff doesn’t know how to support your corporate environment or the applications used within it.

With a multitude of personal devices in your workforce, the support burden may increase and your help desk may not be able to keep up with the unique features and aspects of all the devices. Mr. Madocks concludes that no matter how you allow access to the corporate resources the support burden NEVER disappears.

The support experts from the PC Helps brain-trust, developed a playbook for organizations considering a Bring Your Own Device model:

Don’t just say no to “bring your own technology”: The cat is out of the bag. End users are more productive when they have a vote on the tools they use and their support. PC Helps suggests IT show some leadership and help figure out how to get BYOD (PDF) right so that the company is protected and the users are happy. Recognize that consumerization means giving up some control; learn to live with that.

Listen to the end-users: Create an internal customer advisory group to allow end-users to explain what they want and what they don’t. The article says one of the primary drivers of consumerization is the wish to have work and personal content and capabilities on a single device. Craft a draft set of policies and guidelines based on this input.

Help deskResearch and test your approach: Consider a pilot program before full rollout that includes a mix of key users. Discover the range and types of preferred devices as well as the corporate systems, networks, and applications users will need access to. The blog recommends that you incorporate your findings into the broader rollout plan.

Document and communicate a clear set of policies and guidelines for end-users: Everyone should know what the company policies are for personal devices and where to find them. Explicit review of policies and testing for understanding should be performed from time to time, or as new devices arrive and raise new issues. The policies should set forth:

  • Which devices will be supported.
  • How to request new/more devices,
  • Which apps are authorized,
  • Which apps are forbidden,
  • How to get approval for new apps,
  • What company data is allowed on personal devices,
  • How to get support for devices and applications.

The policies should also answer the following questions:

  • When a device is no longer used for work or an employee leaves, what are their responsibilities to securely deletion corporate data?
  • Where and how will devices be backed up?
  • Who is responsible for backup?
  • Are lock and password-protection required, and how is it managed?
  • Who will provide support?
  • What kind of support questions should be directed to device manufacturers?

ComplexityPlan for a more complex support burden: Allowing personal devices means a world with more devices, which in turn multiplies the knowledge needed from the help desk. There will be more questions on setup, remote access, and use of corporate applications, as well as problems unique to the different devices. There will be more complex support scenarios, such as, how to use Microsoft Office applications on non-PC devices. Be sure you have a support plan and trained people in place.

Don’t rely on device manufacturers for support of your end-users: Manufacturers can handle break/fix and warranty support on products, but they won’t know your corporate policies, processes, nor the core office applications your users work with every day. Apple iPad owners have access to AppleCare and Genius bars, but this is all geared to consumers. AppleCare won’t help with many synchronization issues related to accessing corporate email on the iPad, nor provide urgent support for deadline-related business situations.

a risk to IT’s reputationEnd-users may get the run-around, going to the manufacturer and then to their wireless service provider, to your internal help desk, and to peer support for help, wasting time and productivity on something that could be solved in a single call. Devices for corporate use should have corporate support or they will present a risk to IT’s reputation in the organization.

Prepare your help desk for the task: The help desk in a BYOD IT environment is a different type of organization, one that must be able to respond to the unexpected. Mixed device environments require specialization and expertise, as well as ongoing training and skill-building. Your existing help desk staff may need to be retrained, expanded, or supplemented.

In the end, Mr. Madocks reports that the firms PC Helps assists in consumerization don’t regret their decision. “While consumerization creates complexity for support … The company’s workforce is happier and more productive, and the reputation of IT as a supporter of the business is greatly enhanced.” The end result is generally happier users and happier IT, but there are complications.

rb-

It is my experience that most people who push consumer devices into the enterprise, don’t have a plan. They want their iPads, for valid or not so valid reasons. Some staff seemed surprised when they could not print to the enterprise printer on the enterprise network with the iPad they just brought in.

I place a great deal of the blame at the feet of Apple. I have had Apple engineers look me straight in the face and tell me that iPads are consumer devices and not designed for the enterprise and that Apple does not intend to fix it.

They do not use standard protocols and BYOD proponents don’t even know what Bonjour is, let alone the limitations of Bonjour.
