Satellite is often touted as an alternative to fixed-line access such as cable or ADSL and  has succeeded in providing much faster and often more reliable Internet service, particularly in rural and regional areas, than the standard public system telephone network.
Satellite internet can be accessed even in remote corners of the country. They are easy to install and operate. The internet speed is higher than DSL or cable internet. You can download heavy files in quick time and even listen to online radio uninterrupted. The internet speed is constant and does not fluctuate and Satellite internet does not require huge cabling or telephone connection to access the internet.
There are two types of satellite services you can use: asynchronous and synchronous. Similar to the asymmetrical DSL service, asynchronous means that there are different speeds for upstream and downstream traffic (again, downstream is faster than upstream).
Synchronous satellite services on the other hand, have the same speed for upstream as for downstream, which makes it more suitable to services that are heavily impacted by delays, like video and audio streaming.
Generally these satellite technologies work on one of two principles:
– Data is downloaded from the satellite to a terrestrial base station and from the base station to the consumer by microwave link. The consumer requires a receiving dish or antenna and a standard phone modem for uploading data to the base station and from there to the satellite.
– Data is downloaded directly to the consumer’s satellite dish but a phone modem is still required to upload data to a terrestrial base station and to the satellite.
Data download speeds for consumer systems vary, though you can expect it to be up to 20 times faster then standard dial-up. Speeds can be affected by traffic volume and even bad weather, and costs vary considerably depending on the carrier.
With technology improving day by day, the demand for internet with faster bandwidth and downloading speeds has increased and this in turn has led to satellite internet. With satellite internet there are no cables and no hassles for internet connection and installation. Satellite internet connection is more reliable than a DSL or dial up internet connection.
If you feel that there is a need for changing your internet connection, then opting for a satellite internet connection would be the ideal solution.

Types of broadband

One of the first decisions to be made is what kind of connection you want. There are several options for setting up high-speed services, which all come under the broadband umbrella. However, the type of broadband service you need and have access to will be determined by your speed requirements, budget, and the location (city or regional) of your home or office.

 ISDN
Meaning integrated services digital network, a standard to send video, voice and data over a digital telephone line. Isdn is a circuit-switched telephone network system, designed to allow digital transmission of voice and data over ordinary telephone, resulting in better voice quality than an analog phone. One of the major use cases is Internet access, where ISDN typically provides a maximum of 128 kbit/s (which cannot be considered to be a broadband speed).
In a videoconference, ISDN provides simultaneous voice, video, and text transmission between individual desktop videoconferencing systems and group (room) videoconferencing systems.
 
DSL
DSL broadband technology supplies significantly faster data transfer speeds than dial-up Internet, without a huge investment. It is a cost effective and convenient permanent connection.
Dsl provide digital data transmission over the wires of a local telephone network.
Typically, the download speed of consumer DSL services ranges from 256 kilobits per second (kbit/s) to 24,000 kbit/s, depending on DSL technology, line conditions and service level implemented. Typically, upload speed is lower than download speed for Asymmetric Digital Subscriber Line (ADSL) and equal to download speed for Symmetric Digital Subscriber Line (SDSL).
 
Cable
Cable is considered to be more stable than ADSL, with consistently high speeds. Many  providers offer  bundled deals with your phone and/or cable TV, which can save you quite a bit of cash in the long run. However, the installation process is more complex than ADSL, and may require a tradesman to run a cable into your house from out in the street. The fibre networks that bring you cable TV at home can be more than an addition to your viewing options — it can also be your means to fast Internet access.
 
Satellite
Satellite is often touted as an alternative to fixed-line access such as cable or ADSLand  has succeeded in providing much faster and often more reliable Internet service, particularly in rural and regional areas, than the standard public system telephone network. Internet access via satellite is available worldwide, including vessels at sea and mobile land vehicles
 
Wireless
This data-only system utilises a small base station connected to a wired network or to the Internet and transmits data wirelessly to multiple workstations, which can be desktops, notebooks or even handheld PCs. Each base station can service several users equipped with wireless receiver cards in their computer, and base stations can be overlapped to allow several hundred users to access the network or Internet.
