| Each
BelAir Networks multi-service, platform used to create the
mesh supports backhaul coverage in all directions using antennas
in a circular array. The antennas have a high gain and a narrow
horizontal beam-width, which, together with enhanced radio
performance, provides significant reach extension.
To
get the full benefits of point-to-point radios with directional
antennas and simplify deployment, the BelAir Networks solution
automates antenna beam selection on the backhaul. This eliminates
the need to manually point antennas in the right direction.
The
radio environment is constantly changing and the radios adapt
to these changes on a packet-by-packet basis. In addition,
dynamic power and data rate changes on individual radio links
absorb fast fading and shadowing effects in the radio path.
Radio-aware
routing algorithms choose the best route for traffic through
the mesh based on a number of relevant metrics such as available
capacity, latency and radio link performance.
To
increase system up-time and minimize traffic outages, traffic
from each multi-service platform can be load balanced across
a minimum of two routes to reduce the impact of link congestion
and failure. Alternate paths are continuously calculated and
refreshed so that seamless re-routing of traffic can occur
with minimal packet loss in the unlikely event of a link failure. |
