The term broadband refers to a reasonably high level of Internet access. Different observers have different definitions for "reasonably high level", so we generally go by the definitions provided by the experts. The CCITT standards group defined "broadband” as bit rates greater than 1.5 mbps. In the US National Broadband Plan of 2009, broadband was simply described as "Internet access that is always on and faster than the traditional dial-up access". Service providers such as
O2 have defined their “basic broadband” as a 20 mbps connection with a download limit of 20 GB per month, while their “mobile broadband” is a 3.6 mbps connection with a download limit of 1 GB per month. The monthly cost of such connections is relatively low – less than the cost of a meal at most restaurants. Any small business should be able to afford a broadband connection.
At AutoCAD Architectural, we generally work with customers who have a broadband connection that enables the fast transmission of large graphic files, some of which can be a few dozen megabytes in size, so a standard 20 mbps connection should be sufficient. You can use a slower Internet connection, but you may find it frustrating to wait for your files to download. Also, the longer you wait, the higher the chances of disconnection due to random events, such as power fluctuations or machine error. If you don’t have access to a broadband connection, it might be better to copy your file on a CD and courier it to us.
