X band radar advantages and disadvantages

In telecommunication, a band – sometimes called a frequency band – is a specific range of frequencies in the radio frequency (RF) spectrum , which is divided among ranges from very low frequencies (vlf) to extremely high frequencies (ehf). Each band has a defined upper and lower frequency limit.

The 900 MHz ISM band is very narrow and this limits the maximum data rates . Typically applications such as SCADA and RFID use the 900 MHz band as the data rate requirements are lower than applications found in the 2.4-5 GHz frequency bands.

To prevent interference and allow for efficient use of the radio spectrum , similar services are allocated in bands. For example, broadcasting, mobile radio, or navigation devices, will be allocated in non-overlapping ranges of frequencies.

Frequency f is the number of cycles that an RF electromagnetic wave undergoes per second. Frequency band, sometimes denoted by B, is simply a range of frequencies (e.g. the band from 1-2 MHz).
