Why Vantech's non-contended dialup is quicker

how it works

Currently all Internet Service Providers connect their customers to the Internet with the aid of one of the four companies (called Tier 1 providers) who own the global infrastructure that is the backbone of the Internet. ISP's purchase the required amount of connection to the Internet (called bandwidth) from the Tier 1 providers based on the number of users each ISP has.

See diagram below:

Due to the cost of bandwidth, ISPs calculate their need based on the number of users that they believe will connect at any one time, (usually 1 in 100). However it is likely that 20 to 30 users in every 100 will be online at peak times, this is known as contention. This means you share your connection with other users slowing you down to an unbearable speed or preventing connection to the Internet altogether. At Vantech Media we will always provide enough bandwidth to allow all of our users to get online at any one time at the optimum speed of you equipment.
