Abstract

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.

Claims

1. A method of providing wireless access to a network comprising 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 a time slot for data transmission between the user terminal and the base station;

at the user terminal segmenting data of a first format 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;

recombining the segmented data received from the user terminal into a first format and providing the recombined data to the network;

receiving data in the first format from the network 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;

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; and

wherein data transmitted from the base station to the user terminal is allocated a larger portion of each of the frames than allocated to data which is transmitted from the user terminal to the base station.

2. The method of claim 1 wherein the first format comprises TCP/IP.

3. The method of claim 1 wherein the segmented data is transmitted and received in a Time Division Duplex format.

4. The method of claim 1 wherein the ratio per frame of data transmitted from the base station to the user terminal to data transmitted from the user terminal to the base station is four to one.

5. A method of providing wireless access to a network comprising 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;

at the user terminal, segmenting the data of a first format 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 the network; and

wherein the frequency range and time slot are assigned according to a likely number of users of the network, a likelihood of the users of the network actively communicating information at a given time, and a likelihood of the users transmitting versus receiving data.

6. The method of claim 5 wherein the likelihood of the users transmitting versus receiving data is one to four.

7. The method of claim 6 wherein the likely number of users is 1/8 the number of potential users.

8. A system for providing wireless access to a network comprising:

means for wirelessly transmitting an electromagnetic signal containing identification information from a user terminal to a base station;

means for assigning a predefined frequency range and time slot for data transmission between the user terminal and the base station;

means for segmenting data of a first format at the user terminal into frames of a predetermined length and for transmitting the data from the user terminal to the base station at the assigned frequency range and time slot;

means for receiving the segmented data from the user terminal at the base station;

means for recombining the segmented data received from the user terminal into the first format and providing the recombined data to a network;

means for receiving the data in a first format from the network and for segmenting at the base station the received data from the network into the frames of the predetermined length and for transmitting the segmented data from the base station to the user terminal at a preassigned frequency range and time slot; and

means for recombining the segmented data received from the base station into the first format; and

wherein data transmitted from the base station to the user terminal is allocated a larger portion of each of the frames than allocated to data which is transmitted from the user terminal to the base station.

9. The system of claim 8 wherein the segmented data is transmitted and received in a Time Division Duplex format.

10. The system of claim 8 wherein the ratio per frame of data transmitted from the base station to the user terminal to data transmitted from the user terminal to the base station is four to one.

11. A system for providing wireless access to a network comprising:

means for wirelessly transmitting an electromagnetic signal containing identification information from a user terminal to a base station;

means for assigning a predefined frequency range and time slot for data transmission between the user terminal and the base station;

means for segmenting data of a first format at the user station into frames of a predetermined length and for transmitting the data from the user terminal to the base station at the assigned frequency range and time slot;

means for receiving the segmented data from the user terminal at the base station; and

means for recombining the segmented data received from the user terminal into the first format and providing the recombined data to a network; and

wherein the frequency range and time slot are assigned according to a likely number of users of the network, a likelihood of the users of the network actively communicating information at a given time, and a likelihood of the users transmitting versus receiving data.

12. The system of claim 11 wherein the likelihood of the users transmitting versus receiving data is one to four.

13. The system of claim 11 wherein the likely number of users is 1/8 the number of potential users.
