Project: IEEE P802.15 Working Group for Wireless Personal Area Networks (WPANs) Submission Title: 802.15.4 High(er) Rate Date Submitted: Sept. 2015 Source: Clint Powell, Powell Wireless Commsulting, LLC Contact: Clint Powell, Powell Wireless Commsulting, LLC Voice: +1 480-586-8457, E-Mail: cpowell@ieee.org Re: Developing a 802.15.4 High(er) Rate PHY Amendment Abstract: Development of a 802.15.4 High(er) Rate amendment with minimal changes to 802.15.4 spec. Purpose: To support higher data rates that are more compatible with 32 bit processors Notice: This document has been prepared to assist the IEEE P802.15. It is offered as a basis for discussion and is not binding on the contributing individual(s) or organization(s). The material in this document is subject to change in form and content after further study. The contributor(s) reserve(s) the right to add, amend or withdraw material contained herein. Release: The contributor acknowledges and accepts that this contribution becomes the property of IEEE and may be made publicly available by P802.15.
Proposal • A 802.15.4 amendment providing a higher rate PHY, compatible with the original 250 kbps O-QPSK PHY.
Motivation • In 2003 when 802.15.4 was initially released the 250 kbps data rate was a good fit for the 8 bit microprocessors technology of the day • Jump ahead to 2015, 10+ years later – and 32 bit microprocessors are commonly used when implementing 802.15.4 • Over-the-air data rates for 802.15.4 have increased since then, but… • a higher over-the-air data rate PHY, that is 8-10x that of the original 250 kbps PHY, and is backwards compatible with the original 250 kbpsO-QPSK PHY has not been developed
What is Needed/What are the Benefits • A higher over-the-air data rate 802.15.4 PHY that: • is 8-10x the over-the-air data rate of the original250 kbps O-QPSK PHY (resulting in lower energy and air time per message and increased capacity of the channel) • is backwards compatible with the original250 kbps O-QPSK PHY • has the same occupied bandwidth as the original250 kbps O-QPSK PHY • is capable of simple implementation • is a minimal addition/change to the 802.15.4 standard
