Assumptions Valid for US market 2 major phone OEMs will adopt Ultra Wide Band Vehicle SOP 2 years after phone SOP Flagship share estimated by Bosch from phone Internet

traffic in 2018 in USA Scenarios Only 2 flagships: 19% share Continuous introduction for 2 OEMs: 25% and increasing

Caveat As of 2018, 11% of Android phones cannot support the minimum function set for digital key on Bluetooth!

Perfectly KeylessTechnology Adoption in Smartphones

New functions like UWB or BLE 5.X reach 25% share 2 years after phone SOP, 50% share after 4 years

Localization on UWB

MasterRecommend to package in the IP area, no radio in master (neither BLE nor UWB)

Internally Located BLE/UWB Anchor Node, Center Console PositionProvides good coverage of interior but potentially reduced BLE connectivity range

Internally Located BLE/UWB Anchor Node, Trunk PositionIn a similar location to existing keyless antenna. Oriented so that Anchor “cover” is facing inwards toward vehicle interior

Internally Located BLE/UWB Anchor Node, Roofliner PositionHelps to increase BLE connectivity range and provide good coverage of interior

Fast time to market with SOPs in 2021

Experience with UWB in industrial sector

Strong connections to players in smartphone business through MEMS sensor business

Extensive ecosystem though in-house development (back-end, security) and partnerships(standardization at CCC, IEEE, BLE SIG, mobile phone makers, UWB silicon vendors,…)

High security and localization performance for BLE available from Bosch only
