Put extra distance—up to 10,000 feet—between a PC and your phone jack.
OVERVIEW
If you want to connect to the Internet but your phone jack
is too far from your workstation, our Wireless V.90 Modem Kit
is the perfect solution.
The wireless modem provides a wireless point-to-point link
between an RS-232 device and your 56K modem installed in
an IBM
®
compatible PC running a Windows
®
OS.
With the kit, you get a
Wireless V.90/RS-232 Remote Node
(MDR221A), which
enables local wireless data transmissions,
and a telecom modem node, which bridges the local wireless
link to a telecom system for longer-range communication.
You just connect the modem node to your phone jack
and the remote node to your PC’s DB9 port (a serial cable is
included). You then communicate wirelessly between nodes at
up to 500 feet (152.4 m) indoors. For outdoors or line-of-sight
communications, the kit has a range of 10,000 feet (3048 m).
The modem node has two standard RJ-11 jacks, one for
connecting the phone line and one for plugging in the phone
itself (an RJ-11 cable is included). An autoanswer feature
enables the modem to answer incoming calls over the phone
line automatically.
The modem kit operates in the unlicensed 2.402–2.478 GHz
ISM band using Frequency-Hopping Spread Spectrum (FHSS)
transceivers and can be used in the U.S., Canada, and Europe
(meeting FCC, IC, and CE approvals) without requiring further
certification.
Because it uses FHSS technology, the Wireless V.90 Modem
Kit offers reliable communications in areas with a lot of
electrical interference and in environments typically hostile
to RF signals. It transmits around corners, through walls and
other obstructions—so there’s no need to drill any holes or
conceal any cables, as you would in a complicated wired setup.
Plus, it’s secure. A proprietary protocol ensures the privacy of
your data transmissions. And because the Wireless V.90 Modem
has an industrial-grade design, you can use it in areas subject
to temperature extremes.
You can even use multiple kits in the same area. To bring
wireless connectivity to more PCs, order an extra V.90/RS-232
Remote Node (MDR221A) for each additional computer.
The Wireless V.90 Modem suits both stationary and mobile
communication setups and installs in minutes. Once set up, LEDs
on the units indicate status and operation. A red PWR indicator
informs you that they’re receiving power and a green Link LED
indicates that the units are in range of one another. Rx and Tx
LEDs indicate the receiving and sending of data between the
Wireless V.90 Modem nodes.
TYPICAL APPLICATIONS
By going wireless, you bring a whole new level of flexibility
to your commercial or business Internet access applications.
Ideal for enabling dialup Web networking from remote areas
where phone connections aren’t easily accessible, the wireless
modem kit suits new, retrofit, and even temporary deployment.
Use it, for instance, where retail kiosks, point of purchase
(PoP) displays, or ATMs don’t have convenient local access
to telecom connections. Or check on the status of vending
machines’ merchandise or money without leaving your
workstation.
It’s also great for campus-wide wireless connections. And
in the SOHO environment, you can use the Wireless V.90
Modem as a gateway to wirelessly connect your Internet
appliances to unobtrusive phone jacks.
For mobile Internet users, the wireless modem enables easy
links between devices such as e-mail terminals and Web cafe PCs
without the expense and hassle of wiring new phone lines and
jacks.

FHSS communication.
Frequency-Hopping Spread Spectrum communication
provides error-free wireless transmission, top security, and
high levels of throughput over the license-free radio band.
Many other radio bands require an FCC site license, and a lot
of radio modems on the market are based on technologies
that don’t work in interference-prone applications or extreme
temperatures.
Spread Spectrum wireless modems, including Black Box’s
Wireless V.90 Modem, are designed to endure the extremes
and still provide the performance you’d expect from a hard-
wired modem operating under optimal conditions without
the cost and time needed to obtain an FCC license.
The key to this outstanding performance is a frequency-
hopping transceiver. Narrow-band frequency hoppers use a
predefined algorithm to maintain synchronization and high
throughput between master and remote modems. They
achieve this by continually switching, or “hopping,” from
one transmission frequency to another throughout the
Spread Spectrum band.
The sequence of frequencies is very difficult to predict and
thus nearly impossible to eavesdrop on or jam. If interference
is encountered at any particular frequency, the built-in error
correction detects it and resends the data packet at the next
frequency hop.
And because EMI/RFI interference rarely affects the entire
available bandwidth, and each frequency hop is at least
6 MHz, the radio transmitter has access to as many as 100
frequencies within the spectrum to avoid interference and
ensure that data gets through.
