subsequent content, we will use SDR to capture the GSM packets in the phone during the call and use the Samsung Phone Lock screen Bypass vulnerability to directly obtain Tmsi, KC to decrypt the captured packets and extract the voice content from the call process.Maybe, we can also discuss the security of 4G LTE base station based on Gr-lte Open source project.

With the popularization of 3G technology and the development of wireless standards and technologies such as LTE, NFC, Bluetooth 4.0, cmms B, and MIMO, mobile Terminals need to integrate multi-band main antennas (supporting 2g, 3G, LTE and other multi-standard), as well as GPS, BT, WiFi, NFC, wireless charging and other antennas. As a result, terminal antenna engineers are facing huge challenges: Antenna siz

Where are the locations of Wi-Fi when different technologies compete for the future of mobile highways? Multiple wireless technologies are competing to become the next-generation Transmission System for Mobile Video and collaborative business applications and services. WiMAX and LTELong-Term Evolution) are currently the leader in the WAN field. Qualcomm's ultra-mobile broadband UMB) technology ranks third, although it is eager to run at a speed above Mbps more than twice the speed that
1. Background and objectives The traditional UMTS wireless communication network is basically designed around the core of the voice service, from the development of 3G, LTE and 4G technology in the future, we can all see that the data service driver plays an important role in the change of network architecture. In the future, communication networks will not only integrate a variety of heterogeneous wireless networks, but also integrate wireless networ
4G + 6 years before 5G 5 Gbps network test speed: 5 Gbps Although the domestic TD-LTE and LTE-FDD of the 4G convergence network test license just recently issued, but unable to cope with the communication equipment vendors run faster: a few days ago, Ericsson announced 5G wireless testing, the maximum network transmission speed is 5 Gbps. Although this data is half faster than the theoretical speed of 5g a
With the continuous development of wireless networks, multi-Stream Aggregation (MSA, Multiple Stream Aggregation) can improve the edge throughput by 500% through deep fusion of Multi-standard, multi-carrier and multi-layer networks, realizing the concept of borderless networks enables users to enjoy high-speed and stable data access services wherever they are on the network. It will become a key technology for network evolution in the future. The popularity of smart terminals and the rapid devel
Which Internet of Things strategies and network strategies are distributed by global operators? --> After several years of preparation and development, the concept of IoT was quickly recognized worldwide and became one of the core driving forces of the new scientific and technological revolution and industrial revolution. According to statistics from Strategy Analytics, as of the end of 2017, nearly 20 billion IOT and networking devices will be deployed worldwide and 10 billion more devices
