Hello, everyone! Can anyone tell me that this Bluetooth SIG can actually use technology to track the location of many devices? Although Broadcom invented the new GNSS chip, the Bluetooth SIG(Special Interest Group) developed this new GNSS profile specifically for the exchange of GPS data. All devices that support Bluetooth 2.0 and later can use this profile to easily share GPS location information with other wave blocker device nearby via a nearby Bluetooth connection. What does it offer us? Let's see.

GPS jammers prevent location sharing

• First, all Bluetooth-enabled devices can find your location via Bluetooth, improving indoor tracking. Second, wearables in the future may forget to use GPS for location tracking altogether. The third one is probably the most interesting. You will see that the Bluetooth operates within a radius of only a few meters. Imagine a situation where one of the GPS-enabled devices is located in a room and the other devices don't have GPS tracking. Even so, everyone has Bluetooth integrated. They share GPS data from devices so that attackers can see that all of these devices are currently in one room, not just GPS-enabled devices. It's reverse sharing, you know?
• So of course the answer to your question is yes. But in this case, you're not powerless. cell phone jammer prevent GPS from releasing Bluetooth SIG GNSS profiles, thereby preventing your Bluetooth device from being recognized and shared with other devices in the room.
• I read that Broadcom will be making their new GPS tracking chip in the near future. So I was curious to see if it could find the location more accurately and how to avoid this need. Broadcom recently announced a new GNSS location tracking chip called BCM4752. It is small enough to fit any type of smartphone or other mobile device, and is even twice the size of other similar chips. It has also improved the speed of signal transmission and reception, and has four satellite navigation constellations: GPS, GLONASS, QZSS(made in Japan) and SBAS(QZSS and SBAS all use the same frequency, GPS L1, L2 and L5 bands).

WiFi and bluetooth jammer will block signals from the tracking chip

1. Moreover, the Broadcom BCM4752 chip is already suitable for indoor positioning tracking. To make it work properly, use WLAN and Bluetooth wireless connections and NFC communication. All of these bands, along with GPS and other satellite navigation systems, make this tracking chip an absolute new player in the satellite tracking market. Broadcom, by the way, may already be supplying mobile device makers.
2. Want to know how to get rid of this powerful stalking? It won't be as easy as you'd like, but it's possible. You can combine wave jammers, WiFi jammers, and Bluetooth to block signals from Broadcom's BCM4752 tracking chip. You must also interfere with the NFC signal. Only when all these radio signals are protected can you safely go on this wonderful hunt.
