You Need This WI-Fi Companion



I cannot remember how I survived without wireless
networking. I have one in my home and frequently access public
hotspots in my community to dash off a quick e-mail or instant
message. I have even used airport and hotel hotspots to remotely
manage projects while on vacation or on business trips. Now that I
can connect to the Web anywhere, I'm more efficient than ever
before!
Unfortunately, finding a Wi-Fi hotspot is
sometimes easier than connecting to it. The networking software
built into Wi-Fi equipped Windows Mobile devices is sometimes tough
to use, and networks with encryption and other security measures can
make it difficult to get online. The software applications discussed
in this article can help you find and connect to wireless networks.
In addition, they add some incredible additional features to your
Wi-Fi equipped device.
Locate hotspots quickly
The first step in wireless networking is finding a
hotspot. Wi-Fi is nothing more than a short range, two-way radio
that handles data rather than voice communications. Wi-Fi equipped
Windows Mobile devices come with software that lets you control the
Wi-Fi radio built into the device. You can use the radio/software
combination to "sniff out" the signals coming from a Wi-Fi hotspot,
determine their strength, and establish a connection between the
hotspot and your device.
As mentioned, the built-in networking software
(a.k.a., "Wi-Fi manager") is sometimes difficult to use.
Fortunately, there are third-party solutions available, and one of
the best is Socket Wi-Fi Companion (http://www.socketcom.com/).
This program quickly scans the area for available wireless networks
and shows you each one with their signal strength (Fig. 1) as well
as any encryption measures the hotspot may employ.

Fig. 1: The Socket Wi-Fi Companion gives you
one-tap access to wireless networks in your immediate area.
To connect to a network, simply tap on a hotspot
name in the list and tap on "Get Connected." Wi-Fi Companion will
take care of all the settings and automatically download a security
certificate if the wireless network requires one.
Once you're connected, Wi-Fi Companion offers a
new set of helpful utilities. The screen includes a pop-up menu for
single tap access to surf the Web or check e-mail, as well as for
launching Socket's Wi-Fi utility applications (Ping and Trace
Route).
A special Power Save feature allows you to specify
whether you'd like to have the best battery savings, best network
performance or a balance between the two. This dialog will change
how the Wi-Fi Companion controls the power to the wireless radio to
help you conserve battery power or maintain a stable wireless
connection. You can also select an "automatic management" feature,
which automatically adjusts the power up for better reception, when
you're device is connected to a AC power adapter and down to
conserve battery power, when you're not.
The Wi-Fi Companion software ships with two
utility applications, Wi-Fi Ping and Wi-Fi TraceRoute. These
applications can help you troubleshoot network problems by checking
the range of your network and will check each "hop" your wireless
connection makes to find where delays in communications are
occuring.
Wi-Fi Companion is available from Socket
Communications for $24.99 and a 3-day trial version is available on
their Web site (http://www.socketcom.com/). The
Wi-Fi Companion requires ActiveSync 4.0 to install the application
on to a Pocket PC.
Map your local hotspots
When wireless networks first began appearing, a
hobby called "wardriving" was born. Users would drive around their
neighborhoods with GPS-equipped laptops and map all of the wireless
networks in the area. This information could be uploaded to a Web
site to share with other users. NeoHunt simplifies
wardriving with your Pocket PC. As you move around, the software
displays all of the available wireless networks (Fig 2) on-screen.
If your Pocket PC is equipped with a GPS receiver, the software
integrates with it to map the coordinates of the Wi-Fi networks you
encounter.

Fig. 2: NeoHunt scans the area for wireless
networks and stores the GPS coordinates of each hotspot.
Data can be imported into Pocket Streets to
display where you located hotspots on a street map or imported into
Microsoft's Terraserver. The developer has no immediate plans to
support the WM5 feature that allows shared use of the GPS data. This
means you cannot run another application that accesses the GPS
receiver, (for example, a navigation program that provides driving
directions) while you map hotspots using neoHunt. In addition, I had
difficulty getting the software to work with some Bluetooth GPS
accessories. So make sure you install and experiment with the trial
version of the application to make sure it works with your equipment
before you purchase it.
More information and a link to a trial download
are available on the developer's German language Web site (http://www.playseven.com/) or
on the special English language site he's created for his .NET
applications (http://www.dotnetux.net/). You
can also purchase the software directly from Handango.com for
$15. |
