Frequently Asked Questions


Q: What is VSAT

A: VSAT (Very Small Aperture Terminal) is a communication technology based on a two way satellite ground station with a small dish antenna.  VSAT delivers reliable and constant connectivity.

Q: VSAT Benefits

A: People need access to enterprise, voice, video and data applications wherever they are and VSAT can connect you across a broad range of industries and Geo locations.

The VSAT solution works irrespective and independent from any other networks.

Q: What is Ku and C-Band

A: These are different frequency ranges the VSAT can operate on: 

  • C-Band operates on 4-6GHz, with a larger antenna.  Minimum antenna size is 1.8m. C-Band Networks performs best under any weather conditions.
  • Ku-Band operates on 11-13GHz and the minimum antenna size is 1.2m.  Ku-Band Networks is affected by heavy rain especially in tropical areas

Q: Will I have coverage?

A: Yes, Paratus covers the whole of Namibia

Q: What do I need for a VSAT connection?

A: Every Remote VSAT Terminal consist of an antenna and a modem. The antenna needs to be installed outside and needs clear line of site to the satellite.  The modem will be inside and have an Ethernet interface for connecting the local network.

Q: How long does it take to setup a VSAT?

A: VSAT is a quick deployment of the Antenna and the modem.  VSAT is immune to challenges like terrain and/ or Geo-location.

Q: Is VSAT expensive?

A: VSAT can deliver communication to areas where terrestrial option is unavailable, unreliable or simply too expensive.  Only local infrastructure is needed.

Q: Why is latency so high and what issues can I expect?

A: Latency over the VSAT is >550ms.  This is the time that the signal needs to travel from the earth to the satellite and back.  Most application (http, voice and video) will not be affected by the latency.  Operating over a remote desktop can overcome latency issues for applications that are latency critical. 

Q: How reliable is VSAT?

A: VSAT have a very high reliability providing constant connectivity even if terrestrial networks fail. VSAT is ideal for business continuity with built-in redundancy and automatic back-up services.
