What are some of the specific details involving
point to point protocol?
The Point-to-Point Protocol (PPP) provides a
standard method for transporting multi-protocol
datagrams over point-to-point links. PPP is
comprised of three main components:
- A
method for encapsulating multi-protocol
datagrams.
- A
Link Control Protocol (LCP) for establishing,
configuring, and testing the data-link
connection.
- A
family of Network Control Protocols (NCPs) for
establishing and configuring different
network-layer protocols.
What are some of the specific details involving
multipoint protocol?
Airecomm provides Canopy AP modules which talk to SM
using a multipoint protocol (broadcast).
Canopy AP modules communicate with all Canopy SM in
a network delivering clear, consistent, robust
communication.
What is Point-to-point verses
Point-to-multipoint?
Airecomm systems are available in the Point to Point
protocol which is usually employed in private
networks and broadband backhaul. Point-to-point
connects two buildings, towers, offices, ect. to
each other.
Airecomme systems are additionally available in the
Point to Multipoint protocol which is appropriate to
help distribute to Campus, Enterprise and the
surrounding community.
How do I set the encryption key on a Canopy
link?
The user doesn’t directly set an encryption key. The
user can enter an authentication key and enable
authentication – then that key among other inputs is
used to generate the per-session encryption key.
How is the per-session encryption key
determined?
For the AP-SM link with authentication enabled: If
authentication is enabled, each end calculates the
per-session encryption key using the SM’s factory
installed key, the random number used during the
per-session challenge, and the authentication key,
if one was entered by the user.
For the AP-SM link with authentication disabled: If
authentication is not enabled, then each end
calculates the per-session encryption key using the
SM’s factory installed key and the random number
used during the per-session challenge.
For the Backhaul link with authentication enabled:
If authentication is enabled, each end calculates
the per-session encryption key using the BHS’s
factory installed key, the random number used during
the per-session challenge, and the user-entered
authentication key (entered by the user into both
the BHM and the BHS).
For the Backhaul link with authentication disabled:
If authentication is not enabled, then each end
calculates the per-session encryption key using the
BHS’s factory installed key and the random number
used during the per-session challenge.
I want a secure network – should I use
authentication, or encryption?
Both. Together they give much better protection
against intrusion than either alone.
Is the encryption key (session key) ever
passed over the air?
No, the encryption key is never passed over the air,
encrypted or unencrypted.
Is Airecomm encryption end-to-end or link
encryption?
Current Canopy encryption is focused on protecting
the air link and is therefore link encryption. The
input/output at the module’s Ethernet port is
unencrypted.
What is transmitter noise interference?
Harmonic interference occurs when harmonics or
multiples of a carrier frequency from the offending
transmitter fall into the victim’s band. The effects
are similar to receiver desensitization. If the
signal strength on the harmonic is high enough, it
can either “de-sense” the receiver or in some cases
completely drown out the intended signal. A spurious
signal shows up on a spectrum analyzer as a “spike”.
If this spike is strong enough, it can knock out the
intended signal.
What is the effect of weather and
atmospheric conditions on the 5 GHz radio?
Our data has shown that humidity, rain, snow and
wind have no tangible effect on the 2.4 GHZ, 5.2
GHz, or 5.7 GHz radios.
