    Computer programming notes 2/20

    Today, we did connectivity experiments with the "bullet" ethernet to antenna cable converter and some antennas of various shapes.

    From the computer, we linked a ethernet cable to another one with a power box that would work as POE (power of ethernet), to give energy to the signal.
    Then, the other end of the cable was connected to the "Bullet" ethernet to antenna converter (shown below)
    After that, we connected the "bullet" to different types of antennas, we tried different shapes and tested how many hotspots
    they could reach:
    1) Dish Antenna: generally, the antenna with more range than others, it captures the signal like a concave mirror, making these signals bounce directly to the "focus" of the antenna.

    2) Panel Antenna: Another type of antenna with a great range, with this antenna we were able to catch signals from the Mount Mauna Kea, distant several hundreds of miles from our labs.

    3) Omni Antenna: A more conventional type of antenna with a inferior range, but with a 360° angle of signal reception, me and my science seminar buddy Erina tried to use this, but with little success.

    4) Directional Antenna: Another conventional antenna with medium range, this type of antenna receives signals only on a straight line, its shape reminds of the typical blaster turrets used by the Empire in Star Wars, unfortunately we didn't have the pleasure of trying yet.
