Cosmote of Greece deploys Nokia Microwave Backhaul

Nokia announced that it has upgraded the long-haul microwave trunk network of Cosmote, the mobile operation of OTE Group, Greece's largest telecoms provider and a Deutsche Telekom company, to enhance network capacity and performance, particularly in rural locations of the Greek islands.

Based on the Nokia 9500 microwave packet radio technology, the upgrade is designed to enable Cosmote to meet growing demand from residents and tourists for broadband access in underserved areas of the islands. The Nokia solution will enable traffic backhaul at speeds of up to 1 Gbit/s using IP connectivity for both mobile and fixed networks.

Following the upgrade, Nokia's long-haul microwave technology will enable backhauling of traffic across multiple Aegean islands, with the solution designed to provide fibre-like connectivity as well as backhaul redundancy to improve the reliability of services.

Nokia stated that a key part of the project is the use of microwave technology to deliver broadband connectivity to the island of Kastellorizo, the most easterly of the Greek islands, located more than 150 km away from the nearest network point of presence. Nokia added that by upgrading the existing SDH-microwave trunk-based network, Cosmote was also able to reuse existing passive radio equipment and so reduce the cost of the project.




  • In 2016, Huawei and Cosmote announced the completion of a field trial of Super Dual Band microwave technology enabling multi-Gbit/s backhaul capacity. It was noted that as it rolled out LTE services, Cosmote had been upgrading the RAN and identified the need for greater backhaul capacity. The microwave technology trial with Huawei was designed to help address the increasing demand for mobile broadband applications.

Ericsson Demos 1.2Gbps LTE in Greece with COSMOTE

Ericsson, in partnership with COSMOTE, the unified communications brand of Greece's OTE Group, demonstrated download speeds up to 1.2Gbps in an LTE network.

The demonstration, which took place at COSMOTE mobile network in Greece, used Ericsson’s radio solutions. The downlink speeds were achieved by aggregating three carriers with total 60 MHz of spectrum (3x20MHz), with 4x4 MIMO and 256 QAM, delivered to a Cobham Aeroflex TM500 mobile device.

George Pappas, Head of Ericsson in Greece, says: “The latest Ericsson Mobility Report forecasts 4.6 billion LTE subscriptions globally by the end of 2022. Technologies such as 256QAM downlink and carrier aggregation are essential for delivering high-quality LTE experiences to subscribers in Greece and other markets around the world, and our demonstration with Cosmote showcases Ericsson’s technology leadership in these critical areas.”

Cosmote Hits 500 Gbps with LTE FDD 3x Carrier Aggregation + 256QAM

Cosmote Greece achieved download speeds of 500Mbps in a live LTE network using equipment from Ericsson.

Cosmote is implementing FDD 3xCarrier Aggregation & 256 QAM innovation to their commercial network, boosting performance and market differentiation.

The demonstration, which took place at the Infocom World 2015 event in Athens on November 24, 2015, used Ericsson’s radio solutions and Ericsson Networks Software 16A . In addition, three component 20+20+10MHz FDD LTE carrier aggregation in combination with 256 QAM modulation deployed in a live network for the first time in the European market.

Ericsson said its 256QAM downlink encoding technology provides up to 33 percent higher downlink throughput in good radio conditions. This enables more efficient use of the spectrum allocated to a cell, as well as a 33 percent increase in maximum user downlink throughput.

"OTE Group brings the future of telecommunications today. We invest in innovation in order to be the first to offer our customers pioneering fixed and mobile telecommunications services, while we continue to assertively expand our New Generation Networks and develop the country’s infrastructure. With the consecutive 'firsts' achieved by the OTE Group, such as the demonstration of speeds up to 500 Mbps via our 4G+ network, we confirm our technological superiority and make a difference for our customers," stated Stefanos Theocharopoulos, Chief Technology & Operations Officer, OTE Group.

First 3.5 GHz LTE FDD-TDD 3 Carrier Aggregation Test

Nokia Networks, Deutsche Telekom and Cosmote (Deutsche Telekom’s subsidiary in Greece and leading network operator in the country) have demonstrated a world-first: LTE-Advanced 3 carrier aggregation combining LTE-FDD in band 3 (1.8 GHz) with LTE-TDD in band 42 (3.5 GHz). The showcase, completed with the commercially available Nokia Flexi Multiradio 10 Base Station, confirms the ability of 3.5 GHz LTE-TDD technology to increase mobile broadband capacity and improve the consumer experience.

The demonstration used the Nokia Single RAN Advanced platform, including the Nokia Flexi Multiradio 10 Base Station for both LTE-FDD and -TDD technologies, with its high-capacity TD-LTE-Advanced 8-pipe radio.

“Deutsche Telekom is a real innovation leader. Hand in hand with our NatCos we are shaping the local markets, especially in LTE. Spectrum plays a fundamental role for mobile communications as we look to exploit opportunities to meet the growing demand for network capacity. The demonstration of FDD-TDD 3 carrier aggregation together with our partners, sets a benchmark for a completely new combination of technologies including the increasingly recognized band 42 which will be expected to be a mainstream TDD band," Rachid El Hattachi, SVP Technology Architecture & Blueprints, Deutsche Telekom.

OTEGLOBE Expands with Infinera DTN-X platform

OTEGLOBE, a leading international telecommunications carrier in Southeastern Europe and member of OTE Group, is expanding its European backbone network with the Infinera DTN-X platform. The carrier recently signed an agreement to land a new international submarine cable system, named AAE-1, at its international landing station at Chania, Crete, aimed to transform Greece into a major European Internet gateway to the Middle East and North Africa regions and beyond.

“Our goal is to become the alternative hub in the Mediterranean for the continuously increasing Europe to Asia transit traffic,” said Mr. Andreou, OTEGLOBE’s CEO. “To address this increasing demand, we deployed Infinera's solution which enables us to enhance the scalability of our backbone with one solution from the Mediterranean to the core of Europe.”

“We are pleased to continue to upgrade OTEGLOBE's network,” said Chris Champion, senior vice president, EMEA at Infinera. “With the Infinera Intelligent Transport Network, OTEGLOBE has doubled network capacity and provided increased capacity to its customers at the optical layer. This is a direct result of the deployment of super-channel FlexROADM technology unique to Infinera.”
