Comneon’s GSM/GPRS/EDGE Protocol Stack Family is a complete, flexible software solution for all 2G mobile terminals in markets worldwide. With a flexible modular design and a wide range of features, it is designed to satisfy a broad scope of requirement profiles.

GSM/GPRS ensures high quality and secure mobile voice and data services with full roaming capabilities across the world. It continues to be a mandatory technology for mobile communications due to its availability and its high reliability as well as due to its provisioning of basic access to packet-based data services with ‘always-on’ functionality and Internet-based content.

EDGE/EGPRS pushes the transmission bandwidth a considerable step forward and ensures data transmission rates similar to 3G data rates. It speeds up services such as Internet browsing, e-mail, powerful visual communications, multimedia messaging and location-based services.

Comneon's 2G Protocol Stack Software

Comneon’s 2G Protocol Stack is based on more than 15 years of experience in creating and deploying protocol stack software for mobile terminals. The flexible solution fits to a wide range of products and requirements. Simple mechanisms allow customers to activate GPRS and EDGE functionality when required for their respective products. Based on a common, stable platform, the software
enables terminal vendors to smoothly migrate towards EDGE which is a standard feature today.

The architecture is proven to be easily portable to different hardware platforms. Due to its modular design Comneon’s 2G Protocol Stack is ready to be integrated into any 3G Single Mode Stack solution – either as an essential part of Comneon’s own 3G Dual Mode Stack Family or to complete a customer’s 3G solution with the latest EDGE technology.

Millions of mobile devices – phones and modules – using Comneon’s 2G Protocol Stack software have been sold to markets worldwide. These models created by various companies successfully passed the approval and certification process for its combined GSM/GPRS/EDGE functionality. To ensure product quality and maturity Comneon conducts an extensive IOT and field-test program which covers all major network vendors and operators.
