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.
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.
Region Code
A parameter that offers multiple fixed selections, each of which automatically
implements either the Dynamic Frequency Selection (DFS) standard that is required by
law or regulatory to apply or no DFS, based on the frequency band range and the
selected region.
Registrations
MIB
Management Information Base file that defines registrations for global items such as
product identities and product components. See also Management Information Base.
repl-m
A command that sets up the database replication process on a Bandwidth and
Authentication Manager (BAM) master server, uses SFTP to copy both the database and
the repl-s script to a BAM slave server, and remotely executes the repl-s script on the
BAM slave server. See Master, Slave, repl-s, Secure Shell, and SFTP.
repl-s
A command that sets up the database replication process on a Bandwidth and
Authentication Manager (BAM) slave server. See Master, Slave, and repl-m.
RES
Result. A field in the data that the cmd show esn command generates from the SQL
database in the Bandwidth and Authentication Manager (BAM) server.
RetransLimitExp
Field
This field displays how many times the retransmit limit has expired.
RF
Radio frequency. How many times each second a cycle in the antenna occurs, from
positive to negative and back to positive amplitude.
RJ-11
Standard cable that is typically used for telephone line or modem connection.
RJ-45
Standard cable that is typically used for Ethernet connection. This cable may be wired as
straight-through or as crossover. Later modules auto-sense whether the cable is straight-
through or crossover.
