Maximum transmit power
Maximum transmit power is the maximum power that the PTP 800 is permitted to
generate at the waveguide interface assuming that ATPC is disabled, or the link loss is
high enough such that ATPC is not activated. The equipment limit for maximum transmit
power is defined by modulation mode, band, channel bandwidth and standards body or
region. The spectrum license limit is determined by the maximum EIRP permitted by the
individual license, the antenna gain and feeder loss. The maximum transmit power that
can be configured for PTP 800 is limited by the more restrictive of the equipment limit and
the spectrum license limit.
Maximum transmit power defaults to the maximum permitted as described above, but can
be reduced if necessary using Step 3 of the Installation Wizard, or the Configuration page
of the web-based interface.
Security
PTP 800 provides optional 128-bit and 256-bit encryption using the Advanced Encryption
Standard (AES). The implementation in PTP 800 has been validated against Federal
Information Processing Standard Publication 197 (FIPS-197) in the Cryptographic
Algorithm Validation Program (CAVP) of the US National Institute of Standards and
Technology (NIST).
AES encryption protects all traffic over the wireless link, including in-band and out-of-band
network management traffic. Each CMU behaves as a cryptographic device in which the
Ethernet interfaces transmit and receive plain text data, and the IF interface transmits and
receives cipher text data. The IF cable and RFUs are outside the cryptographic boundary.
