Why WiDi or WiGig?

WiGig

It appears Intel is positioning their Intel Pro WiDi and WiGig technologies for the conference room and docking respectively.  They are more or less forced into this to improve PC (read Intel uP) sales.  They may have been counting on the release of W10 and/or touch PC devices in the enterprise (and consumers) to drive users to buy the 5th generation Intel based platforms, however W10 is delayed and the enterprise is in no hurry to move off the non-touch and adequate OS W7 that they just moved off of XP for.  The Intel messaging was introduced at Intel Solutions Summit (ISS) Dallas this month and so the savvy VAR will tout this messaging to drive PC refreshes at their customers.  Intel really has little else if anything to drive users to buy a new PC.  They provided the VARs with the various messaging tools including .PPT, white papers/case studies, and videos. The videos are cute and also on Youtube; search on “Intel if cables were people”.

This is the easiest if not only way to get customers to refresh, and stay Intel PC, not Android/Chromebook or even Intel Apple.  This is why there is allot of WiGig or wireless docking buzz.  The DocKtor advises embracing the Intel messaging but switch out the solution from Intel WiGig/WiDi to USB3.0 Targus Universal Docking Stations.  Feel free to challenge me or better yet, get me involved with your application when considering the Intel wireless technology as opposed to the fully mature USB3.0 technology.  It really isn’t a fair fight, TUDS wins (and you will too).

Reasons why your should be using TUDS as opposed to WiGig:

  1. Maturity.  TUDS work with all legacy PC with USB2.0 let alone USB3.0, and all future PC with USB including USB Type-C, and MacBooks, and now Android 5.0 and up devices.  Intel WiGig does no work with MacBooks or Android devices and there are no plans for them to.  As of today, WiGig only works with three PC, one HP and two Dell.
  2. Cost.  To get a PC with WiGig the cost adder is about $500 for the higher end processor, more memory, and most important the wireless radio and special monitor with antenna, all this is needed before the dock is even bought.  The WiGig docks cost an additional $269, more than even the Targus high-end ACP77.  Not to mention Vendor lock of using only Dell or HP…
  3. WiGig only replaces one cable.  PCs still need to be plugged in for power and so does the dock. The WiGig docks consume allot of power relative to USB docks.  And with USB Type-C emerging faster and becoming more prevalent then WiGig, your customers aren’t doing themselves a favor investing the costs to be an early adaptor of WiGig.  USB-C yields them a solution to power and data on one reliable up to 10Gbps cable.  WiGi is no more than 5Gbps.  All of TUDS work with type-C today and a type-C native dock is coming Targus soon.
  4. Range.  The WiGig docks work only on line-of-site and only to about 8’, HP recommends about 4’.  TUDS performs at over 13’ using the USB3.0 cable extension.
  5. Warranty.   Targus 3-Years, Dell 1-Year, HP Unspecified.
  6. Reliability.  Ask yourself, “How reliable is a wireless connection (WiFi or BT) compared to a wired (USB) connection?”  The DocKtor was an RF Engineer back in the day, and worked with the 60GHz spectrum (WiGig) and to be sure, it’s challenging to design radios in this spectrum that are not prone to interference.  Also, while the 2.4GHz spectrum is readily available WW, this isn’t as true with 60GHz.  There are government, etc. applications using this bandwidth now that may (read “will”) interfere with WiGig devices.  This will affect performance and may even knock out functionality at times.
  7. Density.  With a USB cable countless docks can be used.  With WiGi a limited number of channels are available, something like 4 to 8.  So, in a dense application i.e. workspace optimization (Intel speak for hot-desking) only 4 to 8 users can be co-located.
  8. Functionality.  I will pick apart the individual specifications of the HP and Dell become more clear, but suffice to say, I am pretty sure they do not do any better than the ACP77 and they are not 4K docks.

Reasons why your customers should be using TUDS as opposed to Pro WiDi:

  1. Maturity.  See #1 above.  Consumer WiDi and Miracast (and Chromecast, AppleTV, Firestick, etc.) have been out for a while but none of these technologies are as interoperable or reliable as USB TUDS or the Targus ACA039 and ACA038.
  2. Cost.  The special WiDi from Actiontek costs $150 and again the PC needs to be a bit special so the cost of an ACP70 is less and adds in GbE connectivity, a second display i.e. for two TVs or projectors, and USB hubbing with USB charging.  The ACP71/77 also add PC charging.  The ACA039 even less.
  3. Warranty.  Targus 3-Years, Actiontek 90-Days.  Note, Actiontek is the only vendor for Pro-WiDi!
  4. Reliability.  See #5 above noting the most customers have has issues even with the “mature” 2.4 WiFi and BT device spectrum, and 5GHz too.

I can go on and on but the above should be enough to compel most understanding buyers to buy into USB3.0 Targus Universal Docking Stations for the single solution to all the problems WiGig and WiDi are trying to address.  Targus will have a WiGig dock when it makes $ense.  Buy into the Intel messaging, but change the solution to TUDS!
