High throughput wireless data communication using transferred protocol data for communication across land-line network
First Claim
1. A data communication method comprising:
- transmitting data signals over a wireless link from a first site to a second site and determining, at the second site, a first communication protocol parameter to be used between the first and second sites based on an error record of the received data signals;
transmitting data signals over a wire-line circuit from a third site to the second site and determining, at the second site, a second communication protocol parameter to be used between the second and third sites based on an error record of the received data signals;
receiving, at said second site, a data signal from said first site and converting the received signal according to the second communication protocol parameter, and transmitting the converted signal to the third site; and
receiving, at said second site, a data signal from said third site and converting the received signal according to the first communication protocol parameter, and transmitting the converted signal to the first site.

Abstract
In a data communication network, a first connection is established over a wireless link between a terminal and a router and a second connection is established between the router and a server over a land-line network. Communication protocol data necessary for communication control with the server is transferred from the terminal to the router. A data signal from the terminal is received at the router and converted into a packet according to communication protocol defined by the transferred protocol data between the router and the server and then transmitted to the server. A data signal from the server is received at the router and converted into a packet according to communication protocol defined by the transferred protocol data between the router and the terminal and then transmitted to the terminal.
