Why does the 600 Series bridge operate in the 5GHz band?
The 5 GHz band offers the
dual benefits of high data throughput and good radio propagation characteristics. The wide
band of spectrum available is subdivided into several channels such that multiple systems
can operate in the vicinity without causing interference to one another.
Is the 600 Series bridge an 802.11a device?
No, although similar, the 600 Series bridge
uses different encoding and radio transmission systems from 802.11a. In areas where
802.11a systems are operating, the 600 Series bridge
will detect the 802.11a radio signals
and choose a clear channel away from any interference.
How much power does the 600 Series bridge transmit?
At all times the 600 Series bridge
operates within country / region specific regulations for radio power emissions. In addition, the
600 Series bridge
uses a technique known as Transmit Power Control (TPC) to ensure that it
only transmits sufficient radio power such that the other antenna can receive a high quality
signal.
How does the PTP 600 Series Bridge avoid interference from other devices nearby?
At
initialization, the 600 Series bridge
monitors the available frequency channels to find a
channel that is clear of interference. In operation 600 Series bridge
continuously monitors the
spectrum to ensure it is operating on the cleanest channel.
How does the 600 Series bridge integrate into my data network?
The 600 Series bridge
acts as a transparent bridge between two segments of your network. In this sense, it can be
treated like a virtual wired connection between the two buildings. The 600 Series bridge
forwards 802.3 Ethernet packets destined for the other part of the network and filters packets
it does not need to forward. The system is transparent to higher-level management systems
such as VLANs and Spanning Tree.
How does the 600 Series bridge provide security for data traffic?
The 600 Series bridge
has a range of security features. At installation time each link must be programmed with the
serial ID of its partner. The two ends of the link will only communicate with one another,
eliminating any chance of "man in the middle" attacks. Over the air security is achieved
through a proprietary scrambling mechanism that cannot be disabled, spoofed or snooped by
commercial tools.
Can I use Apple Macintosh OS X to control and monitor my 600 Series bridge?
Yes, but
there are some restrictions. Mozilla 1.6 or higher is recommended. There are some issues
with Internet Explorer 5.2(IE) and Safari, which could mislead the user.
