Abstract
A system is presented including a first telecommunication device connected to a network at a rate adjusted to improve data bandwidth while data integrity is maintained. The first telecommunication device compresses input data received via the network. Additionally, a first router is connected to the first telecommunication device. Also a gateway is connected to the first router and a second router. Also presented is a second telecommunication device connected to the second router. The second telecommunication device decompresses received data.
