Frequencies

433MHz	433MHz is very popular with long distance flyers Superior long range performance and object penetration
900Mhz	60+ mile range, can be used in mountainous and wooded areas with little to no effect on range Lower frequency signal more easily penetrates walls and trees
2.4GHz	Most transmitters use the 2.4GHz band for communication Equipment is pretty cheap, very common and provides great performance Good 2.4GHz systems will exceed line of sight. Ranges of 1-3km are not uncommon for the better systems
5.8GHz	Pretty much useless to use this frequency to control the plane. It would likely be expensive and our video transmission system will probably be operating on 5.8GHz

Telemetry and Sensor Data

Most popular frequencies used for telemetry are 433MHz and 900MHz.
These frequencies have a benefit of long range without any data loss.
Due to the longer wavelengths these systems are unable to transfer large data rates.

900MHz	Lower frequency signal more easily penetrates walls and trees DIY antennas are easy to make because low frequencies = large antennas Picture quality is quite poor
1.3GHz	Depending on the power, this system can have a range of greater than 40 miles. The downfall of this system is poor video quality due to minimum data rates. Since the wavelength is relatively long, there are stronger penetration capabilities.
2.4GHz	This system can have a range of greater than 15 miles. The downfall of this system is many of the UAVs use 2.4Ghz for control. If 2.4Ghz is used for video, it cannot be used for control or this will cause interference.
5.8GHz	Most popular frequency used for video transmission due to its short wavelength and large data rate transfer capability. Results in clear video compared to the other options available. Due to the short wavelength, this system is only capable of less than 5 miles and has limited penetrating capability.

we probably want to use 5.8GHz for our video transmission systems as it offers greater data transfer capacity
will likely have to do tests with different types of antenna to see which will offer the results
each video transmitter will require a different power, but they are commonly around 200mW
something to keep in mind, if the radio transmitter (used to control the plane’s movements) is operating on 2.4GHz, we do not want our video on 2.4GHz as well.
