Disclosed are a system and method for providing wireless access to a network, such as the internet. The disclosed technique takes into account the inherent asymmetric and bursty characteristics of internet communication to obtain more efficiency in the communication between a user and an access provider. In doing so, the invention provides a technique that can be used to economically provide wireless access to the internet at data rates that are comparable to what a user would receive over ISDN lines. |

DETAILED DESCRIPTION It is an object of the invention to meet the above described need and others and to overcome the limitations which characterize prior art techniques for providing internet access.
It is a related object of the invention to provide wireless access to the internet at data rates that are comparable to what the customer would receive over an ISDN line (i.
e.
, 64 Kbps, with options up to 128 Kbps and 256 Kbps).
It is a further object of the invention to provide a technique for wireless data transmission so that the transmissions among many users can be statistically multiplexed onto a single radio frequency, and more bandwidth may be allocated to the downlink (internet to user) in order to account for the asymmetric nature of the data transmission.
In fulfillment of these objects of the invention, our invention is a system and method of providing wireless access to a network, such as the internet.
As embodied and described below, the invention may comprise the steps of: wirelessly transmitting an electromagnetic signal containing identification information from a user terminal to a base station; assigning a predefined frequency range and time slot for data transmission between the user terminal and the base station; and at the user terminal, segmenting data of a first format, such as TCP/IP, into frames of a predetermined length and transmitting the data from the user terminal to the base station at the assigned frequency range and time slot; at the base station, receiving the segmented data from the user terminal; and recombining the segmented data received from the user terminal into the first format and providing the recombined data to a network.
For downloading data from the base station to the user terminal, the method of the invention further includes the steps of: receiving data in the first format from the network and at the base station, segmenting the received data from the network into the frames of the predetermined length, and transmitting the segmented data from the base station to the user terminal at a preassigned frequency range and time slot; and at the user terminal, receiving the segmented data from the base station; and recombining the segmented data received from the base station into the first format
