Published on

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.

Choosing the Right Access Point Antenna

  1. 1. @GoMimosa @mimosanetworks Antennas are Not One-Size-Fits-All Choose the Right Antenna for Your PTMP Solution Presented By: David Stiff Vice President, Product Management Mimosa Networks
  2. 2. Subscriber Density Surburban 1,000 – 3,000 persons/mi2 Density too high for sectors MicroPOP Utilize Spectrum Reuse Rural < 1,000 persons/mi2 GigaPOP Long Range Towers High Gain Antennas ? In-between Decision depends on available assets
  3. 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 Available Assets
