Challenges For Satellite Internet Infrastructure And Connectivity
Satellite internet access is a boon for those who do not have terrestrial delivery options available. It negates the requirement for ground level infrastructure investments and provides a number of benefits over other delivery methods. However, satellite internet access, much like its competitors, also faces some challenges that can create impediments to its successful deployment and usage. While the ability to provide data transfer options wirelessly via geostationary satellites may have decided advantages over its competitors, this wireless ability itself is fraught with a number of issues that pose serious questions to its relevance. One of the major challenges faced by satellite internet infrastructure is signal latency.
If you have been using satellite internet, some of you might have noticed a time delay in opening web pages or generally slower response times on the internet. Simply put, the turnaround time for data to travel back and forth via satellites 22,000 miles above the Earth takes longer than wired internet on the ground. This automatically makes satellite internet unwieldy for certain types of software or applications dependent on quick speeds. A related problem is that of rain fade. In case of any precipitation, the signals can get impaired and create delays. As weather conditions are unpredictable in many areas, satellite internet access also becomes unpredictable as it’s premised on clear skies. Fresnel zone and line of sight are interlinked issues that can pose serious challenges to satellite internet connectivity.
While line of sight is an obvious issue as satellites require a clear view from the dish antenna placed in your premises, Fresnel zone refers to shape of the signal itself. The signal expands towards the center of its distance between the satellite and the dish and then narrows down again. If the skies are blocked, Fresnel zone can also play havoc with efficient internet speeds. You can contact the nearest satellite internet providers to get the satellite internet that suits your needs. Satellite internet infrastructure however, has tried to address some of these issues by using alternatives like low orbit satellites. These in turn have a new set of issues. Although latency issues get resolved, internet uptime is considerably lower and since they are not fixed in position like geostationary satellites, advanced hardware is required on the ground to keep the signals flowing.
Another alternative is ultra-light atmospheric aircraft. These aircraft can be controlled through computers and provide internet connectivity by way of fixed path flight over identified ground locations. The satellite internet industry is well aware of these challenges and the fact that further investments are being made for launching many more satellites in the future only goes to show that challenges such as these will not impede the development of satellite based internet connectivity.
