 The
antenna size limits the amount of data that you can carry over a circuit. It
is a complicated calculation based upon a client’s location relative to the
satellite power footprint. When we know your requirements we can guide you
to your decision. Satellite bandwidth is not cheap and some companies have designed a product that seems to offer cheap bandwidth. Their solution is to sell shared bandwidth. In other words they will buy 1 Meg from the satellite owner and resell this same bandwidth ten times – they gamble that not all of their clients will need bandwidth at the same time. This gamble often fails at peak times and the clients are left competing for the same space. If the client is running voice, the conversation is broken up and choppy, if they are running data the download speed becomes very slow. Each satellite beam coverage pattern has power and sensitivity contours which are fundamental to the dish size required so your location is important. At the outer, lower level contours larger dish sizes are required. In order to transmit a sufficiently powerful signal to the satellite you need a combination of transmitter power (from the Block Up Converter or BUC) measured in watts, plus a dish size with enough gain. If There may be a trade off to be done if there is the possibility of a smaller dish and high power amplifier or larger dish and low power amplifier. In our design we address all of these facts – giving you enough information to make the choice that is best for your business |
