  • Commented on Wi-Fi Goes Short and Fast-802.11ad
    On a related note, the Wi-Fi Alliance and WiGig Alliance just agreed to merge: http://www.wi-fi.org/media/press-releases/wi-fi-alliance%C2%AE-and-wireless-gigabit-alliance-unify The WiGig Alliance has been working on getting Steve's TV and BluRay player to talk, using the 60 GHz wireless technology that has now evolved...
  • Commented on Passwords: Trojan Horses of a Different Color
    First, kudos on an excellent recap of what's wrong with most passwords used today and why. A couple of questions: You describe the speed of brute-force cracking, but isn't that making an assumption about availability of a password hash to...
  • Commented on Making WIPS more affordable
    Cisco's acquisition of Meraki yesterday is a validation of both cloud-based WIPS and WLAN management. Meraki is a relative newcomer to cloud WIPS, but has long focused on cloud management. For an apples-to-apples comparison of cloud managed WLAN offerings (including...

  • Commented on Is 'Remote Wipe' a Panacea for Protecting Missing Devices?
    Beware that what a remote wipe accomplishes can depend on the OS/version and device make/model. Unless the vendor provides otherwise (e.g., Samsung SAFE), an Android wipe just resets the device to factory defaults, leaving the files stored on the SD...
  • Commented on WiFi Goes Gigabit-802.11ac
    Even older 11n clients will benefit somewhat from newer 11ac clients using less airtime to transmit. Yes, a client would have to be 11ac capable to access 80 or 160 MHz wide channels or use 256 QAM. But no, a...
  • Commented on WiFi Goes Gigabit-802.11ac
    11ac achieves higher data rates in many ways - more efficient encoding, wider channels, more simultaneous streams. Just using an 80 MHz channel instead of a 40 MHz channel doubles max data rate. Using 256 QAM boosts max data rate...
  • Commented on WiFi Goes Gigabit-802.11ac
    Although upgrade involves hardware, it's not necessarily a forklift upgrade. From a technology standpoint, with the exception of MU-MIMO, 11ac is more of an incremental upgrade than replacement for 11n. One sensible strategy to move an 11n deployment towards 11ac...
  • Commented on The Curse of the Mobile Hotspot
    Interesting development regarding carriers and their penchant for preventing installation of third-party mobile hotspot apps on smartphones: On July 31st, the FCC announced that Verizon Wireless (VzW) had agreed to pay a $1.25 million fine for non-compliance with the FCC’s...
  • Commented on Troubleshooting the Mobile Experience (and Protecting Users' Sanity)
    I think the trend (and business case) for BYO smartphones is different than for tablets (iPads etc). Many employers were initially pushed into BYO smartphones by C-level execs who fell in love with the iPhone and refused to carry separate...
  • Commented on More Secure, User-Friendly Hotspots On the Way
    The Wi-Fi Alliance has finally started certifying products under the Passpoint program. The first Wi-Fi CERTIFIED Passpoint products to achieve certification: * BelAir 20E * Broadcom Dualband 11n WiFi and Dual Band 802.11n AP * Cisco CT2500 Series WLAN Controller...
  • Commented on Who Is the Typical U.S. Teleworker?
    Gary, interesting stats. As a long-time teleworker and network security professional involved in remote access, it's interesting to see how teleworking has morphed into mobility. Back in the day, teleworking meant working from a desk in a home office. Today,...
  • Commented on Android's Prospects in the Enterprise: Looking Up?
    Joanie, you hit the nail on the head: risk, fragmentation, and immature IT controls. By the way, Android market fragmentation affects a lot more than just security - device diversity makes it harder to develop enterprise apps that perform consistently...

  • Commented on Wi-Fi 'Voice-Enterprise' Cert: No Longer Stuck On Hold
    Thanks for putting Voice-Enterprise into context, Steve. VoIP over Wi-Fi is certainly just one option for mobile enterprise voice. DECT also uses unlicensed spectrum, but it typically operates in frequency bands that create larger coverage areas and are far less...
  • Commented on Don't Bid 'Adieu' to Apple Bonjour Just Yet
    The capabilities that Aerohive and now Aruba have introduced to propagate Bonjour over distributed WLANs reminds me of what IPsec VPN vendors did long ago to propagate NetBIOS broadcasts to remote subnets interconnected via VPN. VPN-connected remote office Windows users...
