`RoamAbout 2.4 GHz frequency hopping
`wireless LAN adapters
`Freedom of mobility with continuous LAN connectivity for mission-critical
`wireless transactions
`
`For continuous connectivity, with the flexibility to go wherever
`
`your work takes you, go with the RoamAbout 2.4 GHz Frequency
`
`Hopping PC Card or ISA Adapter. Whether you are roaming the
`
`building or just setting up in one of those “hard-to-wire” locations,
`
`these industry-standard wireless LAN adapters provide the reliable
`
`connectivity you need for a wide range of transactional tasks.
`
`Digital’s award-winning
`RoamAbout wireless LAN prod-
`ucts let you choose the wireless
`technology that best suits your
`mobility needs. Our RoamAbout
`2.4 GHz Frequency Hopping PC
`Card and ISA Adapter are the
`ideal choice for data collection
`and other transaction-oriented
`applications that depend on
`continuous, reliable wireless
`connectivity.
`
`These industry-standard wireless
`LAN adapters allow portable or
`desktop computers to communi-
`cate with other wireless devices
`using the same technology.
`What’s more, they let you con-
`nect to a wired LAN via Digital’s
`RoamAbout Access Point — a
`full-functioning wireless-to-wired
`bridge offering the highest bridg-
`ing performance on the market
`today. As a result, you have
`
`RoamAbout 2.4 GHz Frequency Hopping (FH)
`PC Card in Digital’s HiNote PC
`
`access to all other devices con-
`nected to the LAN — either wired
`or wireless — regardless of the
`technology they use.
`
`Benefits
`• Provide continuous wireless
`connectivity for transaction-
`oriented applications
`
`• Ensure security and reliability
`using wireless spread-spectrum
`frequency hopping radio
`technology
`
`• Give you the freedom to roam,
`with access to information,
`services, and devices elsewhere
`in the building
`
`• Save you from the time and
`expense of installing and
`dismantling wired networks
`
`• Support the internationally
`accepted 2.4 GHz frequency
`band
`
`• Make installation fast and easy,
`designed for “plug and play” in
`industry-standard PCMCIA or
`ISA slots

`

`Setting the standard for
`performance and quick and
`easy wireless connectivity
`The RoamAbout 2.4 GHz
`Frequency Hopping PC Card is
`a steady-performance wireless
`LAN adapter that fits into any
`notebook, laptop, or pen-based
`computer equipped with a
`Personal Computer Memory
`Card International Association
`(PCMCIA) Type II card slot. The
`RoamAbout 2.4 GHz Frequency
`Hopping ISA Adapter gives you
`the same steady performance for
`any standard PC/AT desktop sys-
`tem with an industry-standard ISA
`bus slot. Both LAN adapters are
`designed for “plug and play”
`installation using your default
`settings and include ODI and
`NDIS drivers to support common
`PC network operating systems
`such as PATHWORKS, LAN
`Manager, NetWare®, and NetWare
`Lite. In addition, these frequency
`hopping wireless LAN adapters
`are RangeLAN2 compatible.
`And because they support the
`internationally accepted 2.4 GHz
`frequency band, they are ready
`to go all around the world.
`
`Wireless networking for any
`environment
`Digital’s RoamAbout 2.4 GHz
`frequency hopping wireless LAN
`adapters are the ideal solution
`wherever your work takes you:
`
`• Temporary settings — such as
`disaster recovery sites — where
`continuous communications
`are essential, yet the time and
`expense to wire and dismantle a
`network can be prohibitive
`
`• Service organizations — such as
`hospitals — where steady data
`collection is critical
`
`• Dynamic work environments —
`such as warehouses and
`manufacturing sites —
`where accurate inventory
`and production information
`needs to be transmitted from
`anywhere in the site
`
`• Difficult or impossible-to-
`wire environments — such as
`historical sites or buildings
`made of steel, concrete, or
`asbestos — where physical
`structures limit the use of
`wired networks
`
`• High-growth companies —
`such as start-ups, where office
`moves and staff changes are
`frequent
