• 2.4GHz:  Typical WiFi – almost all consumer WiFi products are 2.4GHz
  • Far better at traveling through walls than 5GHz.
  • Disadvantage is that it is typically more cluttered with signals than 5GHz
• 5.2 to 5.8GHz
  • 5GHz band is used for private links & point to point links to avoid interference in 2.4GHz band
  • Typically much less cluttered with signal-traffic
  • Uses spacial multiplexing to eliminate “blind spots” in coverage over a cluttered area such as an RV park (Orthogonal frequency-division multiplexing (OFDM)
  • Walls: Though the 5GHz band is not usually known as the frequency of choice to pass through walls, we have a case-study of 5GHz bridge using Ubiquiti NanoSation M5 passing signal through 3 or 4 walls in an apartment building with NanoStation M5 on each end
• 900MHz: Excellent at passing through trees; best for forested areas
  • TREES / FORESTED AREAS:  If the tree(s) are not too thick or if your link is from a high point to a low point, 2.4GHz will probably suffice.  But if 2.4GHz is over-crowded or the tree(s) are thick, 900MHz would be a better solution.
    • The following 900MHz options can pass through a single thick tree, or a small group of trees.
    • The lowest-cost option for a short link, to pass through trees, is LOCOM9
    • For long-distance links to pass through trees, use NanoBridge M9
    • See our category of 900MHz gear
