Proxy Server
Network computer that isolates another from the Internet. The proxy
server communicates for the other computer, and sends replies to only
the appropriate computer, which has an IP address that is not unique
or not registered.
PTMP
See Point-to-Multipoint Protocol.
PTP
See Point-to-Point Protocol.
QoS
Quality of Service. A frame field that Bandwidth and Authentication
Manager (BAM) provides to the AP and SM about the sustained data
rates and burst data limits of the SM. The format of this field is 64
hexadecimal characters of 0 to 9 and a to f. The BAM SQL database
expresses this field as five contiguous subfields.

Quick Start
Interface page that requires minimal configuration for initial module
operation.
Radio Signal Strength
Indicator
Relative measure of the strength of a received signal. An acceptable
link displays an Radio Signal Strength Indicator (RSSI) value of
greater than 700.
RADIUS
Remote Authentication Dial In User Service
Random Number
Number that the Bandwidth and Authentication Manager (BAM)
generates, invisible to both the SM and the network operator, to send
to the SM as a challenge against an authentication attempt.

Recharging
Resumed accumulation of data in available data space (buckets). See
Buckets.

Reflection
Change of direction and reduction of amplitude of a signal that
encounters an object larger than the wavelength. Reflection may
cause an additional copy of the wavelength to arrive after the original,
unobstructed wavelength arrives. This causes partial cancellation of
the signal and may render the link unacceptable. However, in some
instances where the direct signal cannot be received, the reflected
copy may be received and render an otherwise unacceptable link
acceptable.
