In a wireless communications system, after a high data rate user is admitted and a supplemental channel is assigned to the user, a control message is sent to a receiver to communicate for power ramp-up and ramp-down profiles. The control message contains parameters of a data rate, a starting time and a duration of time as group in assigned fields in the message which is provided by a control signal source. In response to the control message, a controller provides a rate controllable signal with reference to the parameters of the control message to a data encoder. A bursty input data stream is fed to a buffer. The data encoder withdraws the data from the buffer in response to the rate controllable signal. The bit rate transitions in the bursty input data stream are smoothed with reference to the parameters. There is provided an output data stream having smoother data rate transitions than the input data stream. It is possible to solve problems with 3G CDMA systems which have sudden interference changes resulting from the bursty nature of high-speed data transmissions.

The method of claim 1, wherein the beacon includes a sequence number representing a current routing cycle. 6. The method of claim 1, further comprising: determining if there is a previous default gateway identified; and deleting the previous default gateway from memory. 7. The method of claim 1, further comprising, for each client: collecting all beacons; and selecting a single beacon to rebroadcast. 8. The method of claim 7, wherein selecting a beacon comprises: identifying a number of hops between the server and the client for each beacon; and selecting the beacon with the lowest number of hops. 9. The method of claim 1, further comprising: sending a reverse beacon to the server; and constructing a client tree in the server, wherein the server has a path to all clients. 10. A method of wireless connectivity comprising: broadcasting a beacon by a server, the beacon including a sequence number representing a current routing cycle; receiving and storing the beacon at the client, the client further retaining information indicative of a path to the server; rebroadcasting the beacon by the client; upon a client receiving a beacon, determining if a beacon has already been received for this routing cycle; and if no beacon has already been received for the routing cycle, storing a routing path to the server from the beacon. 11. The method of claim 10, further comprising, if the beacon has already been received for the routing cycle: determining if this beacon has a higher sequence number than a prior beacon for this routing cycle, and if so, storing the current beacon in memory. 12. A method of wireless connectivity comprising: broadcasting a beacon by a server, the beacon including a sequence number representing a current routing cycle; receiving and storing the beacon at the client, the client further retaining information indicative of a path to the server; rebroadcasting the beacon by the client: wherein the beacon includes a sequence number representing a current routing cycle; upon a client receiving a beacon, determining if a currently received beacon represents an optimal path for this routing cycle; and if the current beacon represents the optimal path, identifying a default gateway in the current beacon, and storing the default gateway. 13. The method of claim 12, further comprising: determining if there is a previous default gateway identified; and deleting the previous default gateway from memory. 14. The method of claim 12, further comprising, for each client: collecting all beacons; and selecting a single beacon to rebroadcast. 15. The method of claim 14, wherein selecting a beacon comprises: identifying a number of hops between the server and the client for each beacon; and selecting the beacon with the lowest number of hops. 16. The method of claim 12, further comprising: sending a reverse beacon to the server; and constructing a client tree in the server, wherein the server has a path to all clients. 17. A method of wireless connectivity comprising: broadcasting a beacon by a server; and receiving and storing the beacon at the client, the client further retaining information indicative of a path to the server; rebroadcasting the beacon by the client; further comprising, for each client: collecting all beacons; and selecting a single beacon to rebroadcast; wherein selecting a beacon comprises: identifying a traffic monitoring code (TMC) for each of the beacons; and selecting the beacon with the lowest TMC. 18. A method of wireless connectivity comprising: broadcasting a beacon by a server; and receiving and storing the beacon at the client, the client further retaining information indicative of a path to the server; rebroadcasting the beacon by the client; furt
