Proposal for UWB MMS Options in IEEE P802.15.4ab Amendment

Slide Note

Submission by Michael McLaughlin from Qorvo presents missing MMS options in the IEEE P802.15.4ab amendment for future-proofing, including benefits such as improved link margin, longer range, and lower power consumption. The proposal emphasizes technical advantages and recommends optional implementation to avoid competitive disadvantages.

May 2024 doc.: <15-24-0329-00-04ab> My Credentials Founded the world s most successful UWB startup, Decawave Started 15.4a task group in 2003 with like-minded individuals Fed up with the politics involved in the UWB wars Have worked on UWB ever since (21 years) The fledgling study group decided that 15.4a s mission would be to select best technical solution, and to leave politics out of our considerations Am getting on in years, so this, 4ab, will probably be my last IEEE standard Michael McLaughlin (Qorvo) Submission Slide 2

May 2024 doc.: <15-24-0329-00-04ab> Missing MMS options for future proofing 4ab 15.4ab is currently missing two future-looking capabilities Option for 32 fragments Options for 8?? and 16?? fragment lengths Technical reasons why we should not block these options Enables 3dB extra link margin for 32 fragments Buried first paths 41% longer range Enables up to 75% lower power consumption in both Tx and in Rx for the shorter fragments It s optional, i.e. not mandatory, so no-one has to implement it These peak powers are future looking, but we believe future silicon should be capable Technical reasons against NONE Political reasons why someone might want to block this Fear that a competitor will outperform their solution Don t be that someone Michael McLaughlin (Qorvo) Submission Slide 3
