Abstract

A method and device for communicating physiological or control data between a portable device and an information system via telemetry. The system includes at least one portable device, and usually many, each having an I/O port for bidirectionally communicating physiological or control data in the form of IP data packets via telemetry. The portable device in operation includes a layered network interface that supports a standard internet-based networking protocol (IP) stack and PHY and MAC layers. The system also includes an information system connected to a wired network through a networking switch, and having a port for bidirectionally communicating data via telemetry with the portable device. The access point may include a program that converts the IP data packets between the RF PHY and MAC and network, such as Ethernet, PHY and MAC layers and further may include a server such as a BOOTP/DHCP server to support a dynamic assignment of an IP address to a number of portable devices.

Claims

1. A system for communicating physiological or control data between a portable device and an information system via telemetry, comprising:

At least one portable device, the portable device having an I/O port for bidirectionally communicating physiological or control data in the form of IP data packets via telemetry, wherein the portable device in operation includes a layered network interface that supports a standard internet-based networking protocol stack and RF PHY and MAC layers;

An information system including at least one access point, connected to a wired network through a networking switch, and having an I/O port for bidirectionally communicating physiological or control data via telemetry with the portable device, wherein the access point and the portable device in operation includes a program that converts the IP data packets between the RF PHY and MAC and Ethernet PHY and MAC layers and further includes a server to support a dynamic or static assignment of a network identifier to the portable device.

2. The system of claim 1, wherein the RF PHY and MAC layers are DECT based.

3. The system of claim 1, wherein the RF PHY and MAC layers are selected from the group consisting of Zigbee, 802.15.1, 802.11a/b/g/e, and NBFM.

4. The system of claim 1, wherein the RF operates within the WMTS band.

5. The system of claim 1, wherein the portable device is battery-powered or wall-powered.

6. The system of claim 1, wherein the portable device or the information system, or both, further includes a program for adaptive compression based on a network header of the physiological or control data.

7. The system of claim 1, wherein the converted PHY and MAC layers are Ethernet layers.

8. The system of claim 1, wherein the server is a BOOTP server.

9. The system of claim 1, wherein the network identifier is an IP address.

10. The system of claim 1, further comprising an access pointer controller associated with the access point.

19. The method of claim 10, wherein the employing a server to support a dynamic or static assignment of a network identifier to each portable device includes employing a server to support a dynamic or static assignment of an IP address to each portable device.

11. A method for communicating physiological or control data between at least one portable device and an information system via telemetry, comprising the steps of:

Bidirectionally communicating physiological or control data in the form of IP data packets via telemetry between at least one portable device and an information system,

wherein the portable device in operation performs steps including transmitting data using a standard internet-based networking protocol stack and RF PHY and MAC layers; and

wherein the information system in operation performs steps including converting the IP data packets between the RF PHY and MAC and Ethernet PHY and MAC layers and employing a server to support a dynamic or static assignment of a network identifier to each portable device.

12. The method of claim 11, wherein the RF PHY and MAC layers are DECT based.

13. The method of claim 11, wherein the RF PHY and MAC layers are selected from the group consisting of Zigbee, 802.15.1, 802.11a/b/g/e, and NBFM.

14. The method of claim 11, wherein the RF operates within the WMTS band.

15. The method of claim 11, wherein the portable device is battery-powered or wall-powered.

16. The method of claim 11, further comprising adaptively compressing the data based on a network header of the physiological or control data.

17. The method of claim 11, wherein the converting the IP data packets between the RF PHY and MAC and Ethernet PHY and MAC layers includes converting the IP data packets to Ethernet PHY and MAC layers.

18. The method of claim 11, wherein the employing a server includes employing a BOOTP server.
