Why Bluetooth in the enterprise is still a pain

Wanted: real Bluetooth standards

Bluetooth products have a certain cache. They are sexy and smart-looking, they are small and they can be fun to use. But supporting them from an enterprise IT perspective can be a real toothache, and may require some significant extractions, or at least careful planning.

Bluetooth is short-range wireless, meaning it covers a range of about 25 feet. Its most popular implementation has been hands-free headsets for cell phones, and indeed there are dozens of models to choose from, some of which are quite good. The headsets from Jabra, for example, are akin to jewelry and some are so small that it's easy to forget you've got one on your ear. If all you're doing is using a headset on your phone (a process called "pairing"), then these products are pretty solid.

But if you want to do more than have a cute headset for your cell phone users, you will quickly find that there is no real standard. Sure, there are plenty of phrases that look like standards. Just take a look at this acronym soup:

- A2DP (Advanced Audio Distribution)

- AVRCP (Audio Video Remote Control)

- BIP (Basic Imaging Profile)

- OPP (Object Push Profile)

- HSP (Headset profile)

- HFP (Hands-free profile)

- GOEP (Generic Object Exchange Profile)

Lack of support for different profiles

Not every Bluetooth product supports every profile, and some of these - like A2DP which is used to send stereo sound to a headset -- are still being worked on and are particularly problematic.

Well, that is just the start of how hairy Bluetooth is. Some Bluetooth USB dongles - not to mention the built-in Bluetooth support in desktops and laptops -- don't support all the various profiles, so you could get into a situation where you have a Bluetooth keyboard that doesn't talk to your PC, but a headset that does, with the same dongle. Or, you have a Bluetooth keyboard that installs software that gets in the way of a Bluetooth headset, because the two devices support different profiles. This isn't yet a consumer-friendly place to be, let alone an enterprise IT friendly place.

Microsoft Office 365/Dell XPS 15 2-in-1

I’d recommend a Dell XPS 15 2-in-1 and the new Windows 10 to anyone who needs to get serious work done (before you kick back on your couch with your favourite Netflix show.)

Brother PT-P750W

It’s useful for office tasks as well as pragmatic labelling of equipment and storage – just don’t get too excited and label everything in sight!

The Brother MFC-L8900CDW is an absolute stand out. I struggle to fault it.

MSI GT75 TITAN

I need power and lots of it. As a Front End Web developer anything less just won’t cut it which is why the MSI GT75 is an outstanding laptop for me. It’s a sleek and futuristic looking, high quality, beast that has a touch of sci-fi flare about it.
