Modernizing Internet Service Delivery Via Satellite Broadband

Satellite broadband is one of the fastest rising wireless Internet technologies to date. GSM, Edge, HSPA and Wi-Max remain widely used in many countries and service providers, but not all communities can enjoy these networks. Satellite broadband, despite its high cost, is being used by a growing number of ISPs and cellcos to connect rural villages and islands not served by conventional wireless cell sites.

Satellite broadband is one of the fastest rising wireless Internet technologies to date. GSM, Edge, HSPA and Wi-Max remain widely used in many countries, but not all communities can enjoy these networks. Satellite broadband, despite its high cost, is being used by a growing number of ISPs and cellcos to connect rural villages and islands not served by conventional wireless cell sites. One-time fee to get a satellite dish running could be ten times higher than a typical modem or router from terrestrial ISPs. Nevertheless, millions of corporate and household users can attest to the cost-efficiency of satellite broadband. Despite its cost disadvantages relative to other technologies, satellite broadband guarantees stable wireless connection even in areas not reached by the cell sites of mobile broadband providers.

VSATs and satellite dishes serve as the main upload and download links in a satellite topology. Commercial satellites are generally positioned 20,000 miles from Earth, and they move at the same direction as Earth, thus their orbital position is called geostationary (not changing when viewed from Earth).

Ka band satellites, which offer the highest bandwidth in satellite spectrum, can close the geographic barriers between the server and client, providing fast Internet access almost anywhere. Once geostationary satellites picked wireless data, the electronic signals are sent back to Earth in the nearest hubs which are connected to the Internet. These facilities are known as teleports or VSAT farms. The hubs pass the request to the Internet server and send the response to the geostationary satellite. The signal is sent to the satellite dish of the end user. As the cycle shows, satellite dishes and VSATs are the critical links in satellite communication services.

The positioning of satellite antennas is a very important factor in signal optimization. Satellite antennas should directly face the geostationary satellite of the carrier. Geostationary satellites never change their position relative to Earth. Thus, tilting the antenna away from the satellite source will lead to a decrease in broadband speed and signal strength.

Although building commercial satellite fleet requires very huge investment, the technology serves as a cost-efficient communication channel for local communications providers that want to venture into rural markets. Recent Ka band satellites work as reliable backhaul networks across local and international territories, even in areas where cell signals do no exist. Satellite Internet so far is the best wireless technology available in small towns and villages where cell signals are unreliable.

Building cell towers in remote, unpopulated areas goes against the business interests of local ISPs and communications carriers. Developing these technologies means spending millions of dollars with little guarantee of fast returns on investment. But with the help of satellite carriers, deploying wireless service becomes less costly since satellites have very large coverage. Even mountains, oceans, and deserts and uninhabited islands are covered by existing geostationary satellites. Satellite signals can facilitate all online activities like VOIP calls, interactive games, video streaming, chatting, emails and web surfing.

Cost is one of the reasons why satellite Internet is not as popular as HSDPA or GSM. Ka band satellite dishes come with a $200-$300 price tag. Customers usually cannot install the satellite dish or VSAT themselves. The cost of residential satellite dish installation is estimated at $100, while the cost of monthly satellite broadband connection with 6-Mbps speed is estimated at $20.

Many providers are offering installment plans to help their first-time customers bear the cost of satellite connection. Another form of financial help is broadband aid from local governments . This type of assistance is currently available in the US, Australia and UK.
