November 6, 2019 – Comtech EF Data Corp. had its Heights™ Networking Platform selected by Telefonica for a multi-year program to upgrade Vivo Brazil and Telefonica Argentina mobile networks in support of 2G, 3G and LTE backhaul. To complement the Heights™ Networking platform, Telefonica also ordered RF amplifiers. Today, both Brazil and Argentina are experiencing high growth in terms of mobile traffic and subscribers as customers transition from 2G to 3G and LTE to experience mobile Internet. Regulators in both countries realize the value of connecting the unconnected to bridge the digital divide and have established challenging performance requirements for Mobile Network Operators (“MNOs”) to reach new markets with high quality solutions. Comtech EF Data has supplied its award-winning and bandwidth-efficient satellite modems with optimization features to Mobile Network Operators for over 20 years. A constant drive to innovate and to drive down the total cost of ownership and improve Quality of Experience enables MNOs to profitably offer services in the most diverse and challenging environments.
