KoolSpan U: Weekly Word Wednesday – GSM and CDMA

Global System for Mobile Communications (GSM) and Code Division Multiple Access (CDMA)

Global System for Mobile (GSM) Communications is the second-generation cellular network standard (2G). It has the widest deployment and is based on smaller cells with simpler protocols, which allows for a lower cost of deployment than its competitor, Code Division Multiple Access (CDMA), a channel access method used by various radio communication technologies. CDMA is a form of multiple access communications, where several transmitters send information simultaneously over a single communication channel. This allows several users to share a band of frequencies, and is found in 3G mobile telecommunications networks.

Why do these two networks matter?

Despite the convenience of SMS messaging, actual text transmissions have limited security due to the cellular networks they travel across — GSM and CDMA. With SMS messages going across GSM and CDMA networks, text transmissions (and their proprietary value) are vulnerable. KoolSpan’s TrustChip technology provides optimal security when communicating over these networks.

Also, through KoolSpan’s TrustCall voice encryption, all voice communications through the GSM network are secure. Your phone calls and SMS messages are kept secure over the GSM and CDMA with the TrustCall integration in KoolSpan’s TrustChip. The hardware-anchored encryption provides optimal protection.
