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 profile.
Notebook Synchronization, File and Printer Sharing, Multi-user Gaming
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.
