Different attributes of microwave Link frequency ranges

We have 3 main frequency ranges in microwave Links

  • Traditional band 6-42 GHz

  • V band 60-75 GHz

  • E band 71-86 GHz

  • Traditional band used for long distances and medium capacity Links

  • Because the channel bandwidth is from 7 to 56 MHz

  • Capacity of the Link depends on 2 Factors related to frequency range :

  1. Bandwidth of channel
  2. S/N

That’s according to Shanon theory.

  • V band (specially 60 GHz) used in small cells Links because it has high attenuation due to Gases.

  • It has the advantages of frequency reuse, but the distance of coverage is low.

  • E band is from 71-76 GHz and from 81-86 GHz.

  • Channel bandwidth is high (from 250 MHz up to 2 GHz).

  • E band can cover approximately from 3-5 km distances.

  • E band has higher capacity than traditional.

We widely used traditional and E bands in microwave Links.
