Choosing the correct antenna for the Mimosa point-to-multipoint (PTMP) solution is critical to delivering a high-performance wireless network. This webinar will review how to get the best ground coverage based on the subscriber density, distances, interference levels and terrain challenges; deployment options for density versus performance, and how to identify quality antennas.

Decision depends on available assets

3. ¡ GigaPOP - Tower Deployment
¡ Mount: Typically high on a tower, town-tilt based on height and
subscriber location
¡ Coverage: 1 to many sectors with A5c, depending on coverage and
capacity
¡ Broadband feed: Fiber or wireless backhaul
¡ MicroPOP – In Community Deployment
¡ Mounting: Rooftop level on a hub home roof, utility poles, trees,
limited towntilt
¡ Coverage: Single 360 coverage with A5-14, 20-30 subscribers typical
¡ Broadband feed: muni fiber or wireless shorthaul

30. C5 Placement and Channel Reuse
C5 requires a minimum of -25 dBr signal separation between
RSSI from multiple A5 access points for same channel reuse.
AB
¡ C5 only has 10 dBr signal
separation on RSSI from A5 A
and B
¡ C5 unable to de-correlate
signals resulting in high PER
¡ A5 A & B need to be on
different channels
