5-16 Frequently Asked Questions Airmux-200 Ver. 1.750
Q: What type of security is offered on Airmux-200?
A: Airmux-200 has three levels of security:
1. AES hardware mechanism
2. Each unit uses a unique SSID link-specific code (up to 24 alphanumeric
characters)
3. Proprietary protocol protects from eavesdropping from other systems.
Q: Can we use horizontal and vertical polarization on the same frequency to
double the number of wireless links?
A: Installing two Airmux-200 systems in the same band with cross polarization
provides 20–25 dB separations. Nevertheless, since there are reflections, the
cross polarization separation is decreased and spatial separation is
recommended.
Q: Could you add the frequency of 5.735 to the manual selection in order to
increase the number of 20 MHz channels to six?
A: Currently the system provides fixed channels, with one manual frequency
setting. The manual setting provides flexibility of spectrum selection, including
5.735 MHz.
Q: Can we mange Airmux-200 using SNMPc other than the supplied management
software that comes with the units?
A: Yes. The Airmux-200 is SNMP-based. Airmux-200 can be managed when using
other SNMP software after implementing RAD MIBs.
Q: Can Airmux-200 be managed and configured via Telnet?
A: No. Use only the Airmux-200 software manager.
Q: Can I use Airmux-200 with any vendor’s external antenna?
A: Yes. RAD supplies the Airmux-200 external ODU with an N-type typical
connector. Any vendor’s external antenna that can be cascaded to our external
unit can be used without problem. Please note that dB losses in the cascading
cable between the external ODU and antenna should be taken into consideration.
(In the supplied cascading cable of one meter we have 1 dB loss)
Q: Do we need to add external arrestors on Airmux-200 cables?
A: The Airmux-200 ODU includes arrestors and lightning protection. Therefore
there is no need to add additional arrestors.
Q: What is the actual Ethernet data rate and maximum throughput?
A: The maximum net throughput of Airmux-200 is full duplex 18 Mbps.
Airmux-200 is a symmetrical system
Q: What is the sensitivity for each rate of the Airmux-200?
A: The rate sensitivities are:
