3 Common RF bands used for VSAT internet

 


Satellite VSAT communication is split up into diverse types of Radio Frequency (RF) bands. They are used widely for Satellite Connectivity in Africa, and are known to have separate uplink (Tx) and downlink (Rx) frequencies.  These bands ideally also require distinctive RF components (LNB and BUC) and are suited to varied applications. Common RF bands used for VSAT internet are:

  • C-Band: VSAT C is majorly used for data and voice communications. It can also be used for backhauling. While this band requires a comparatively larger antenna that is usually above 1.8m (6ft), owing to is low frequency range it is able to Performa better under adverse weather conditions.
  • Ku-Band:  Ku Band is extensively used for distance learning applications, consumer direct-to-home access, as well as enterprise and retail connectivity. Antenna sizes for it range from 0.9m -1.8m. Due to its high frequency, it requires a smaller antenna than a C-band.
  • Ka-Band: Ka-Band in Africa is ideally used for two-way consumer broadband communication, and involves dishes that range from 60cm-1.2m in diameter. The transmission power of these bands is greater than C or Ku-band beams.

Detailed insights into RF bands and VSAT Teleport in Africa can be found on the web.
