Point to Point and Point to
Multipoint
Point-to-Point
telecommunications is most
recently referenced regarding
wireless data communications for
Internet
or
Voice over IP
via
radio
frequencies in the
multi-gigahertz range.
It also includes technologies
such as
laser
for
telecommunications
but in all cases expect that the
transmission medium is line of
sight and capable of being
fairly tightly beamed from
transmitter
to receiver.
Point-to-Point is sometimes
incorrectly referred to the
peer-to-peer initializes P2P, or
Pt2Pt, or variations of this.
Point-to-Point is distinct from
point-to-multipoint
and broadcast. In the
telecommunications signal
typically is bi-directional,
either
Time domain
Multi-plexed
or
channeled. In hubs and switches, a
hub provides a
point-to-multipoint (or simply
multipoint) circuit which
divides the total bandwidth
supplied by the hub among each
connected client node. A switch
on the other hand provides a
series of point-to-point
circuits, via
micro
segmentation,
which allows each client node to
have a dedicated circuit and the
added advantage of having
full-duplex
connections. |
