CeBIT 2002: AVM Combines ISDN, DSL and Bluetooth Technologies - Bluetooth Technology Demonstrations: DSL over Bluetooth - IP Networking over Bluetooth

    Berlin/Hanover (ots)

Two technology demonstrations by AVM
present innovative new applications for Bluetooth at CeBIT 2002. At
Stand C48 in Hall 13, AVM exhibits the first use of Bluetooth in
combination with ADSL. Complete Internet access over the fast ADSL
line is delivered to up to seven users by Bluetooth wireless
technology. The Bluetooth PAN profile (Personal Area Network) also
makes its premiere here. In this network, all PCs communicate using
TCP/IP over Bluetooth. This means that SOHOs and private users can
set up Windows file and printer sharing applications as well as
Internet access without complicated LAN cabling. Alongside these two
technology demonstrations, AVM presents extended application
scenarios with the ISDN access point BlueFRITZ! AP-X, using Bluetooth
to connect a Palm PDA and a Sony video camera directly to ISDN.
    Wireless ADSL Internet Connection with Bluetooth
    AVM also demonstrates the feasibility and benefits of ADSL over
Bluetooth with the combination of FRITZ!Card DSL and BlueFRITZ!. The
two new products team up to combine the convenience of a wireless
connection with the speed of ADSL Internet access. The AVM solution
uses BNEP (Bluetooth Network Encapsulation Protocol), the Bluetooth
protocol that carries Ethernet over the wireless link. The ADSL
users' PPPoE data is encapsulated in Ethernet frames and fed into the
ADSL line at the access point. The efficient Bluetooth protocol L2CAP
(Logical Link Control and Adaptation Protocol) provides data
communication over the wireless link. The ADSL/Bluetooth
demonstration features the world's smallest wireless Bluetooth
client, BlueFRITZ! USB. At 12 grams and no bigger than your
fingertip, BlueFRITZ! is ideally suited for use with PCs or
notebooks. Bluetooth provides optimum conditions for fast surfing
enjoyment over 768 kbit/s ADSL: a range of up to 100 meters,
integrated data encryption with 128-bit keys, user data rates of 723
kbit/s with asymmetrical bandwidth distribution through ACL
(asynchronous connectionless) communication, as well as MD5 (Message
Digest 5) envelopes. Compared with other wireless technologies,
Bluetooth offers significantly lower hardware costs, lower power
consumption, more robust operation and simpler handling.
    PAN Profile for IP Networking
    AVM also demonstrates full TCP/IP networking among PCs using the
Bluetooth PAN profile. PAN uses BNEP, the Bluetooth Network
Encapsulation Protocol, to transport common networking protocols over
wireless links. In the presentation, AVM's ISDN access point
BlueFRITZ! AP-X and up to seven clients form a complete piconet, an
ad-hoc TCP/IP-based wireless network. Because TCP/IP is the standard
data communication protocol in the Internet and in almost all network
operating systems, including Windows, support for TCP/IP makes a wide
range of applications available. Thus PAN makes it possible to set up
a personal network among all the Bluetooth devices that support this
    Notebook Synchronization, File and Printer Sharing, Multi-user
    Alongside the CIP profile for the connection to ISDN, AVM's PAN
support also adds the value of simple, wireless TCP/IP networking -
for today's TCP/IP-based peer-to-peer applications in Windows
operating systems, for example, such as notebook synchronization,
file and printer sharing, gaming and much more.
    CIP Profile Ideal for ISDN - ISDN Video Over Bluetooth
    The AVM fair exhibit demonstrates the performance of the Bluetooth
profile CIP - the Common ISDN Access Profile - in wireless ISDN
communication. The presentation is centered around Internet access
over one and two B channels with data compression, color fax
transmission, a two-channel H.320 video telephony connection and SMS
text messaging to terrestrial lines over Bluetooth. The CIP profile
organizes CAPI-based communication between the ISDN Bluetooth client
and the ISDN access point, so that the Bluetooth link is completely
transparent to CAPI-based applications. All ISDN services and
features using both D and B-channel protocols are available over
Bluetooth, including the full range of PC-controlled data, fax and
voice communications over one or two B channels as offered by a
conventional ISDN card such as FRITZ!Card PCI, for example. A CAPI
client, such as an ISDN application on a notebook, communicates with
the ISDN access point using CMTP, the CAPI Message Transport
Protocol. This means the client can answer incoming ISDN calls, and
up to seven piconet clients can be assigned individual Multiple
Subscriber Numbers. Since February, 2002, AVM's BlueFRITZ! products
have already included full support for CIP Version 0.95 in the
reference implementation. The future Version 1.0 will be available as
a software update.
    BlueFRITZ! Gives PDAs Direct Access to ISDN
    In future, the BlueFRITZ! ISDN access point will also provide
dial-up Internet access to Bluetooth devices without explicit ISDN
capability. AVM demonstrates specific applications, including ISDN
transmission of images from the Sony DCR-IP7 video camera. A Palm PDA
at the fair stand also makes use of a direct connection to ISDN via
the BlueFRITZ! access point. Both devices use the DUN profile, which
was originally designed for Bluetooth communication with analog
modems. Unlike the CIP standard, however, which supports all ISDN
services, the DUN profile only permits very basic access to the
Internet. Yet although the DUN profile does not support ISDN features
such as channel bundling, data compression, and fax transmission, DUN
integration still offers advantages to BlueFRITZ! users: the AVM
product provides direct access to the digital ISDN communication
network even for Bluetooth products without native ISDN support.
