Background
 5GHz is important for automotive applications
 Provides adequate bandwidth for automotive use cases
 Less congested
 Doesn‘t interfere with Bluetooth, which is important for hands-free
calling in vehicles
 Global regulations are not harmonized
 Makes product certification complex (homologation)
 Some bands are indoor only in certain countries
 Automotive use is typically considered outdoor
 DFS is difficult in automobiles
 Radar detection was developed with fixed access points in mind
 DFS bands not reliably available for vehicular use

Notes
• Note 1: there are additional regional variations for countries
including Australia, Brazil, China, Israel, Korea, Singapore,
South Africa, Turkey, etc. Additionally Japan has access to at
least one channel below 5180 MHz.
• Note 2: DFS = Dynamic Frequency Selection; TPC = Transmit
Power Control; SRD = Short Range Devices, 25 mW (+14dBm)
max power.
• Note 3: Chinese regulations from

Summary
 No 5GHz spectrum is currently available for automotive use
in Japan (without DFS)


Regulations are under review
New proposals may come to light later in 2016 – but may not help
WLAN in cars
 Europe only allows operation in 5.725-5.850 under the Short
Range Device rules (25mW = 14dBm)


This is adequate for most in-vehicle applications
Not all mobile phones support this band
 Changes to regulations will almost certainly happen going
into WRC-19
