We hate to burst your bubble, but there's just no way wireless
enterprise users will be able to roam the entire globe without hitting
a few snags here and there. Yet.
It's not to say that there
aren't solutions to the issue of global roaming. It's definitely
doable. The problem, however, doesn't really lie with the technology.
Honestly, the technology is almost there. The problem lies with the
network owners and operators, and, to an extent, governments. This is
why organizations like the Mobile Enterprise Alliance have formed
programs like the "<a
href="http://www.mobileenterprise.org/roam.php">Global Roaming &
Authentication Initiative</a>" to help spur change. The MEA has
sent an agenda with four goals that will standardize security and
network technologies so that they all work together more seamlessly by
creating standards. This is a noble goal.
Even though it should
be getting easier, though, connecting to the Internet or your Intranet
wirelessly remains to be a serious pain in the tuckus, especially if
you are on the road. True, embedded Wi-Fi, Bluetooth, 3G data cards and
soon WiMAX increase the number of options, but they often only serve to
aggravate and annoy and add to expense accounts.
Any enterprise
worth doing business with will have some modicum of security software
installed on their employees' equipment. As necessary as it is,
security software can hamper and even prevent connecting to certain
networks if they are deemed unsafe, especially wireless networks. What
does this mean for the enterprise worker traveling on business to
less-than-civilized regions of the globe where technology is often
patchworked together? Tough luck.
Another component is IT policy
administration. Similar to security software, policy management makes
sure users are connecting and behaving as the corporation wants them
to. Can't find free Wi-Fi, but the hotel's $20 a day connection is
starting you in the face? Some corporations won't have it. This can be
roadblock number two.
Then there's the networks. While the 3G
data networks are capable of handing off data calls, from one cell to
the next Wi-Fi networks are not so adept at it. Then there's things
like FMC, where a call is originated on a 3G network, but once the
802.11 radio and security software senses a trusted Wi-Fi network, it
switches the from the 3G network to the Wi-Fi network. With voice
calls, these hand-offs are absolutely possible, though not commonplace
just yet. Data sessions can be handled the same way, but they, too are
not commonplace.
While these technology issues may seem to be a
problem, they really aren't. They'll be solved soon enough. The real
issue remains the interoperability across countries and regions.
Enterprise
data users are going to have to simply wait for things like the MEA
standards to arrive (which could be 4-7 years) and continue to live in
purgatory--where the Holy Grail of connecting seamlessly to ubiquitous
networks with world over is within reach--until then.
