Wyse's new windows terminal is a
wireless and keyboardless wonder
A lot of products come and go through the Windows NT Magazine Lab. When we receive a product that grabs our attention, you can be sure the product
is unique. Wyse Technology's Winterm Wireless 2930 clearly falls into this
category because it is the first device we've seen that offers mobile,
keyboardless access to existing DOS, 16-bit Windows, and 32-bit Windows
applications.
With the Winterm Wireless 2930, you can walk around your office building
while you gleefully cruise the Web. Medical professionals can use the terminal
to update patient information as they make rounds in a hospital. Quality control
engineers can use the terminal to track production in large manufacturing
operations. Anyplace you want computer access but cannot reasonably put a
computer is a good place for the Winterm Wireless 2930.
To deploy the Winterm Wireless 2930, you must build a supporting
infrastructure using the following components:
- An Intel-based server running Citrix Systems' WinFrame: The WinFrame
server is the application server for the environment. WinFrame can host DOS,
16-bit Windows, and 32-bit Windows applications.
- At least one wireless hub: The hubs give the Winterm Wireless 2930 entry
points into your traditional LAN. You can overlap hub coverage to provide
seamless connectivity throughout a building.
- CruiseConnect by Cruise Technologies: CruiseConnect manages the connection
between the terminal and the server and handles the difficulties that can crop
up when a terminal moves from one hub zone to another.
You can buy these items individually, or you can purchase a starter kit from
Wyse that includes a terminal, a wireless hub, a copy of WinFrame, and the
CruiseConnect software.
Putting the Piece in Place
I evaluated Wyse's starter kit, which included the Winterm Wireless 2930, a
Proxim RangeLAN2 Access Point (model 7520) wireless hub, and version 1.6 of
WinFrame with five user licenses. The CruiseConnect technology is integrated
into the Winterm Wireless 2930 (no setup or configuration required) and comes on
a CD-ROM for the server side of the link.
The first step in deploying the Winterm Wireless 2930 is to install
WinFrame on a server. Wyse does not modify the WinFrame software it provides in
the starter kit--you can use an off-the-shelf version of WinFrame 1.5 or 1.6.
WinFrame is based on Windows NT Server 3.51, so make sure you install it on a
server that contains components, such as video adapters, that NT 3.51 supports.
I overlooked this point and ended up swapping out my network and video adapters
for NT 3.51-friendly adapters. For additional information about WinFrame, see
Mark Smith, "Thin Is In," September 1997.
Installing WinFrame is as easy as installing NT 3.51, although you need to
take a few extra licensing steps. After you install WinFrame, you must apply
additional WinFrame Service Packs (SPs). Never install Microsoft NT SPs on a
WinFrame system, always use the WinFrame SPs that combine the NT SPs with
WinFrame-specific modifications. Wyse provides documentation on which SPs you'll
need, and includes them on CD-ROM.
If you plan to use the Winterm Wireless 2930 in an all-IP network
environment, forget it. The current combination of the Winterm Wireless 2930,
the wireless hubs, and the CruiseConnect software rely on IPX as the network
protocol. (Wyse Technology claims that as of this writing, TCP/IP has replaced
IPX.) Under the Wyse wireless network design, the WinFrame server uses the
Service Advertising Protocol (SAP--part of the IPX protocol suite) to broadcast
the server's availability on the network. The Winterm Wireless 2930 picks up
those broadcasts to identify which servers are available.
I connected my WinFrame server to a 10Mbps Ethernet network. I enabled
support for both TCP/IP and IPX. I didn't need the TCP/IP protocol for the
Winterm Wireless 2930, but I wanted the manageability that comes with TCP/IP
(e.g., support for ping, FTP, Simple Network Management Protocol--SNMP). At this
point, I had to install the CruiseConnect software on the server using the
Wyse-provided documentation and CD-ROM. This operation was painless and
uneventful.
After I had the WinFrame server in place and humming, I moved to the next
step--installing the wireless hub. The Proxim hub I received in the starter kit
hooked into my Ethernet network with ease and supported connections within a
500-foot radius. If I needed additional coverage, I could have deployed
additional hubs in overlapping zones. The Proxim hub supports IP and IPX, so you
can integrate into an IP-managed network. However, because I was using only IPX,
I ignored the IP configuration of the hub. In a real IP network, you want to at
least set up the IP address of the hub so you can manage it as part of your IP
network. Because I could ignore the IP configuration of the hub, all I had to do
was connect the hub to my network and a power source, and turn it on.
