Check Point Research (CPR) found a security vulnerability in Qualcomm’s mobile station modem (MSM), the chip responsible for cellular communication in nearly 40% of the world’s phones.
If exploited, the vulnerability would have allowed an attacker to use Android OS itself as an entry point to inject malicious and invisible code into phones, granting them access to SMS messages and audio of phone conversations.
Qualcomm provides a wide variety of chips that are embedded into devices that make up over 40% of the mobile phone market, including high-end phones from Google, Samsung, LG, Xiaomi and OnePlus.
In August 2020, Check Point Research (CPR) found over 400 vulnerabilities on Qualcomm’s Snapdragon DSP (Digital Signal Processor) chip that threatened the usability of mobile phones.

A severe vulnerability in a system on certain Qualcomm chips, which has been patched, potentially could have enabled attackers to remotely control Android smartphones, access users text messages and call histories and listen in on conversations, according to a new report from researchers at security company Check Point Software Technologies. We have no evidence the vulnerability is being exploited, the spokesperson says. For this vulnerability to even begin to work, a device would need to be severely compromised to start with, which would be a bigger problem.

LTE and 5G Broadcast Market Outlook-2026
4G LTE is the latest technology in the mobile broadband market. LTE can provide a data speed of up to 30 Mbps and LTE Advance can even provide a speed of 100 Mbps. Use of internet in mobile devices such as tablets, phablets, smartphones, and mobile data cards has fueled the adoption of mobile broadband service across the globe. The development of new mobile applications that provide video streaming, video calls, and many other real-time functioning features, has increased the need for high-speed mobile broadband internet.
Increased need for higher data-rates and greater spectral efficiency are the primary factors driving the market growth. Implementation of LTE in the public sectors such as public safety as well as in defence and security further drives the market. These applications require high-speed communication during emergency; therefore, LTE is the best-suited network to feed this need. Furthermore, changing custom

《Device-to-Device Communication in LTE-Advanced Networks: A Survey》
The 3rd Generation Partnership Project (3GPP) has recently developed device-to-device (D2D) communication to cope with the explosively increasing mobile data traffic.
The D2D communication uses sidelink that is based on the single carrier-frequency division multiple access (SC-FDMA) scheme because of its low peak-to-average power ratio (PAPR) [
Myung, H. G., Lim, J., & Goodman, D. J. (2006). Single carrier FDMA for uplink wireless transmission. IEEE Vehicular Technology Magazine, 1(3), 30–38].
In addition, the demodulation reference signal (DMRS) is designed to support multiple input multiple output. 点赞 2
