- Run WiFi adapter/card in 802.11B mode rather than 802.11G mode for more range / distance
- WiFi adapter/card: Should have an antenna jack and the jack should be RP-SMA, rather than other types of antenna jacks
- Frequent travelers should carry a mount for their USB wireless adapter with them, to keep their antenna by the window when in hotel rooms or RV.
Parabolic-type antennas are always the best 7 for point to point links: Also known as “dish” or “grid: antennas.
If you are familiar with Ubiquiti equipment: The NanoBridge series is the best equipment for point-to-point links: One NanoBridge on each end of the link. For very long-distance links (over 7 miles): Use a Ubiquiti RocketM5 with a RocketDish on each side of the link: Use the 30dBi RocketDish (2-FT diameter) for less than 20 miles. For more than 20 miles, use the RocketDish 34dBi, which is 3FT in diameter.
Long-range wireless links:
If you are not an expert, and you are experimenting with trying to make a very long-distance link: Try this:
- Use signal booster with a high-gain antenna on one end, and test the link.
- If it’s not enough signal-strength: Put a high-gain grid antenna (such as the A24 Grid Antenna above-left) on both ends.
- 2.4GHz frequency is far better at penetrating walls than 5GHz frequencies. See more advantages and disadvantages of the frequencies
- Long-range wireless links: Use signal booster with a high-gain antenna on one end: See example network diagram. Test and if it’s not enough signal-strength; put a high-gain antenna on both ends.
- TREES: 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.
- See example of bridge passing signal through 3 or 4 walls in an apartment building with NanoStation M5 on each end
To reach a signal higher or lower than your elevation: Use smaller dBi omni dipole antenna: 2dBi, or 5dBi (not 9dBi or 12dBi). Of the omni-directional portable antennas, 7dBi has the optimal balance between horizontal and vertical range. Read details
