can be powered using 9V-30V DC. A 10W power supply is recommended.

3.4 DSRC Radios

DSRC is a two-way short-to-medium-range wireless communications capability that

permits very high data transmission critical in communications-based active safety

applications.

The DSRC radios support 802.11p and can transmit at power levels beyond 23

dBm. The range of these radios is 450-500m and it can be adjusted by using the transmit

power setting. Antenna diversity is supported in both the DSRC interfaces.

3.5 GPS

MW-1000™

comes with a built-in GNSS that can provide the following:



Up to 10 Hz update rate



GPS, GLONASS, QZSS, Beidou Constellations are supported



DR Position Calculation with sensors



Location accuracy of 2m with WAAS (2.5m without WAAS)

Note

: WAAS is enabled by default.

3.6 Antennas

MW-1000™

can accommodate the following antennas:



Two 5.9GHz passive DSRC (4 when diversity is used)



One GPS active antenna (max of 20mA)

3.7 Storage

MW-1000™

platform can support:



1MB flash memory for saving sensitive data



64K EEPROM for saving configuration and manufacturing data



Up to 16 GB eMMC
