This article elucidates the advantages and benefits of VSAT over Fiber with microwave last mile, and explains why a VSAT network is an excellent alternative to terrestrial connectivity in third world nations.
5 Features to Evaluate Before Choosing Your Internet Services
- Better Availability
The connectivity rate (uptime) for VSAT links are 99.7% whereas the connectivity rate for fiber links at best can be 98%. This means that in the course of an entire year, a VSAT link may have a downtime of around only 26 hours. Fiber on the other hand, has a much worse connectivity rate, with downtime per year of 175 hours or more.
- Superior Reliability
VSAT links are wireless links which are not affected by the political or social developments in the country, but fiber links are strictly controlled through the relevant ministry, and prone to governmental decisions. Fiber infrastructure facilities are extremely vulnerable to natural disasters as well, whereas a VSAT network consists of only a satellite, a teleport NOC, and a VSAT terminal, and the number of opportunities for network outages is significantly reduced. For fiber, network outages can occur at any point along the infrastructure, while a complete VSAT network can work independently of terrestrial infrastructure and maintain connectivity as long as the equipment can be powered.
- Better Mobility
VSAT equipment can be easily relocated, unlike fiber links which require the relocation of high towers that are usually permanently installed with concrete bases. The relocation of fixed VSAT terminals can be done quickly and safely without specialized tools or heavy machinery, while portable and mobile VSAT equipment are the epitome of mobile connectivity, allowing for communication while on the move.
- Cost Effective
The startup cost for VSAT terminals are usually lower compared to Fiber links which require high towers for the microwave last mile. This is especially true for far-flung and remote locations, where Fiber links require more powerful last mile equipment and very high towers to operate. VSAT on the other hand only needs a normal VSAT terminal to operate, and it does not require access to terrestrial infrastructure, making it the most cost-effective means of high-speed internet access.
- Multiservice Platform
Different types of VSAT terminals can support any kind of requirement such as internet on a ship at sea, internet for moving vehicles (combat vehicles), internet for the press and the media (fast deployable), and internet for very remote locations (even deep into forests or wilderness).
Although internet over fiber is much lower in cost for the bandwidth, world statistics show a growth of VSAT internet users worldwide, even in the USA. We are still witnessing new satellites being put into geostationary orbit for communication purposes. With the rapid growth in the number of internet users, the VSAT industry has been getting its good share of new incomers to the internet world.
