A parabolic satellite dishVSAT technology is used in defining two-way satellite communications for individuals, households, and companies. The main components of the VSAT network are a central hub, the VSAT technology satellite and earth stations. However, there are challenges to using this technology, and these challenges may manifest in each of these components independently or concurrently. The following are the challenges of using VSAT:

The inevitability of latency

Latency refers to the delay between the transfer of data. Some web technologies, for instance, constantly require stable transmissions. The delay of even half a second may have unlikely consequences.

Solution: Satellite stabilisation, so the antenna needs to refer to the horizon and True North. It should continually point at the satellite used in transmitting and receiving signals.

The Line of Site Requirement

Communicating through VSAT satellites needs line of sight, which means an unobstructed view of the satellite is needed so the antenna could function optimally. Structures or even mountains that can block the transmission will affect the link performance.

Solution: Stabilised antennas must be used in areas with a clear line of sight because the antennas must point at the satellite at a one-degree accuracy.

The Impact of External Factors

Environmental conditions affect the quality of the signal and its transmission. Again, weak signals have costly consequences. Seamless reliability at the infrastructure level must be met first. This is where the performance of the entire system must be established to deliver advanced broadband services.

Solution: Stronger signals despite the harsh elements through using an antenna with the right size, powerful transmitters and reliable frequency band.

Once people realise the potential of using VSAT technology, there is no going back. Though using VSAT technologies has its cons, the secret to stronger and uninterrupted transmission is being proactive about dealing with the possible negatives.
