If you're
like me, you've probably grown weary of looking for phone cords to
plug your laptop into, only to find that 1). they don't exist or
are the wrong type; 2). they don't reach across the room or into
the next room where you need to be or where your laptop is located.
Maybe you've even grown weary of fighting with your 12 or 10
year-old for the only available modem phone line in the house. If
this fits your domestic and office Internet situation, then Proxim has a
rather elegant solution for you.
With their
line of RangeLAN products, Proxim has been previously well known
for their corporate and university based wireless LANs. Thanks to
Proxim, on many college campuses and corporations, one need only
load some software, plug in a PCMCIA card and viola! Wireless
Internet (and if needed) intranet access anywhere on campus or
corporate headquarters.

With their Symphony line, Proxim now extends this wireless availability to the
home or small office. To make this work on your laptop you need two
pieces of hardware. The first is the Symphony modem which hooks
into a standard phone jack. Next you'll need the cordless PC card
that goes into your PCMCIA slot and communicates with the modem.
The modem is an analog 56k modem and communicates with the PC card
via 2.4 GHz radio waves at 1.6 Mbps. The maximum radius between
card and modem is 150 feet. Ideally, the modem should be located
off the floor. Set up with the card's bundled software is
straightforward. Just hook up the Symphony modem (making sure it's
turned on), insert the PC card and then load the software. The
manuals that come with modem and card are well-detailed and even
give solid troubleshooting advice. Availability of the card and
modem can be found through Proxim's on-line store which lists
several on-line resellers. I found the best price to be at
NECX.
Once you're set up you have several options. The first thing you'll notice is
that you have a virtual wireless network that can be configured as
a multiple user network or as a single user. You can pick whichever
ISP account(s) you currently use and Proxim will dial it for you
via the network and Symphony modem. Or if you choose, you can allow
your individual ISP dialer setup software to select the Symphony
modem and dial it via it's own dialing software or through Windows'
Dial-Up Networking. If you don't plan on allowing multiple users or
your network, I would opt for the latter dialing option as
Symphony's dialer will occasionally have problems with area codes.
Additionally, I found that on my laptop, unless I disabled most of
the background programs in the System Tray, adding ISP's to
Symphony's menu had the tendency to cause a crash. In addition,
certain ISP's such as AOL, will only function in Symphony's single
user mode.

The real beauty and flexibility of this product is the ability to have
multiple users share the same modem and same ISP access
simultaneously without tying up more than one line. At
home, this avoids many spats. Aside from the laptop, the Symphony
can also function with a modem card installed into a standard
desktop PC. Additionally, let's say you use one type of network in
the office (e.g. Ethernet), Symphony remembers your original
network settings on installation so that when you go home, you can
switch between Symphony and your office network.
A word of warning however for those of you dwelling in the more rural or
suburban areas. Since phone line integrity in those areas are worse
than in metropolitan zones, Symphony has the tendency to dial in
and then lose the connection after several minutes. The reason
according to their tech staff is that the modem grabs the
connection at full tilt and that some suburban phone lines with
inferior line quality, can't handle the high rate. Their
recommended fix is to "dumb down" the modem rate to 33.6k (easily
done through the Control Panel settings on the laptop) which does
the trick. They also state that they are working on this rural
problem.
As you can tell, I think this a really nifty product that takes the couch (and
bed) potato surfing concept to paraphrase Woody Allen, to a whole
other level. If wireless mobility at home or office with your
laptop is the goal than Proxim's Symphony is the answer. In the
future I plan to look at the Symphony in tandem with Proxim's
products for Windows CE-based products.
