General Questions
Q: What wireless standards can Systemonic's silicon systems
be build to handle?
A: 802.11a, 802.11b, HiperLAN2, and MMAC. It is our intention
to support the enhancements to 802.11, e.g. 802.11g, 802.11e, 802.11f,
once these standards have been defined.
Q: If I use a Systemonic silicon system that supports 802.11a
and 802.11b for my wireless LAN card, what standard will the silicon
system focus on when near an 802.11a and 802.11b Access Point?
A: Because Systemonic's solution supports multiple WLAN protocols
in software, it is possible to detect what network is currently
available and to connect. The application software can be written
to prioritize speed in which case the user would be connected to
802.11a.
Q: Are there any legal issues regarding the use of your chip
solution outside EU countries (US and Japan)?
A: To our knowledge there are no legal or export limitations
to the use of Systemonic solutions outside of the EU. However, certain
countries may be under trade embargo due to the encryption standards
used.
Q: Is it possible for you to provide IP of your chip for the
future generation of our products?
A: Yes, that is an option to be negotiated.
Q: How can you provide us technical support?
A: Technical support is provided by our application and support
group via email, telephone or fax. On-site support is possible depending
on the contractual conditions.
System Integration Questions
Q: What are the mechanical and electrical specifications of
the H01 baseband processor?
A: mechanical and electrical specifications of the H01 baseband
processor:
- The H01 is delivered in a 176 µBGA package.
- The package size is 15x15 mm², the height is 1.5 mm.
- Maximal clock rate: 120 MHz.
- Operating voltage: 1.8V (core); 3.3V (I/O).
- Bus supported: generic ROM like interface to connect to Flash
or micro controller.
- Temperature range: -40° to 85°C.
Q: Does the H01 provide clock signals for external components?
A: In order to reduce the number of external components the
H01 clock generation module also generates some clock signals for
external processors. The H01 employs an on-chip PLL in order to
generate all internal and external clocks. These clock modules can
be turned on/off during runtime.
Q: Does Systemonic provide any facilities for site test of deployment
and interoperation test?
A: No. Systemonic does not provide facilities for site test
of deployment and interoperation.
Q: Any special considerations to be used for Ad-hoc network?
i.e. no AP is present?
A: Ad-hoc networking is part of the HiperLAN2 and IEEE 802.11a/b
standards.
On-Chip Peripheral Questions
Q: What encryption modes are supported by the HiperSonic?
A: Encryption may be:
- WEP as specified in 802.11 (40 bit key)
- Modified WEP (128 bit key)
- WEP2 as specified in 802.11e security (128 bit key)
- DES or 3DES as specified in HiperLAN2
WEP2 is a modification of WEP, based on RC4, but with greatly enhanced
security. WEP, WEP2, DES and 3DES are hardware accelerated in the
HiperSonic Chipset.
Interface Questions
Q: Does the HiperSonic provide a stand-alone solution?
A: No, a protocol processor is needed to run the MAC layer.
This would be the host processor in the laptop in the case of NIC
applications.
Q: How does the communication take place between the protocol
processor and the H01 baseband chip?
A: The communication between the protocol processor and the
H01 baseband processor is message based. Communication takes place
via the 16 bit wide FIFO interface which is used for passing data
as well as control and status messages between the two chips. API
is provided.
Protocol Processing Questions
Q: Will there be any big differences in API, program size of
the protocol processor and that of the HiperSonic for HiperLAN2
and IEEE 802.11a?
A: The HiperLAN2 protocol is much more complex than 802.11,
so the program size of the protocol stack will be considerably larger.
Furthermore, HiperLAN2 handles more OSI layers so that the API has
to be different. Since the PHYs of HiperLAN2 and IEEE 802.11a are
similar, there is not much difference for the DSP.
Software Development Questions
Q: Could you provide your plan to be able to provide protocols
for different standards?
A: The present HiperSonic solution supports both IEEE 802.11a/b
and HiperLAN2 today and will be extended to support other standards
as they are released
Q: Does Systemonic provide software tools to modify the firmware
of the H01?
A: Currently, the H01 software development is exclusively
done by Systemonic. However special agreements are possible to enable
our customers to have access to the development tools.
Q: Can you provide device driver software for PCI and CardBus?
What kind of software format and which type of OS is supported?
A: We will provide device driver for all major operating
systems (e.g. Windows 98 SE, Windows 2000, Windows XP, Windows ME,
Linux).
