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

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 kbps
O-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 original
250 kbps O-QPSK PHY (resulting in lower energy
and air time per message and increased capacity of the
channel)
• is backwards compatible with the original
250 kbps O-QPSK PHY
• has the same occupied bandwidth as the original
250 kbps O-QPSK PHY
• is capable of simple implementation
• is a minimal addition/change to the 802.15.4 standard
