France Telecom Tests 100Mbps VDSL2

France Telecom claimed a world first, with the announcement that it had commenced laboratory testing of VDSL2 transmission systems with speeds of up to 100Mbit/s on standard copper lines. The technology, which is based on similar DMT modulation to ADSL and ADSL2+, uses an extended frequency band to 30MHz to achieve the required high transmission speeds.

Achieving these high speeds over existing copper plant is going to be critical for telcos as they start to deploy widescale video and triple play services. The move by the broadcast world towards high definition (after decades of delays) means that more bandwidth will be required for video services.

The First European Research and Innovation Exhibition held back in June in Paris provided France Telecom with the opportunity to demonstrate that high-definition television over copper was finally becoming a reality, thanks to networks with increased bandwidth capabilities and compression techniques. Today, the company is stepping up its efforts by testing VDSL2 transmission systems - which were finally approved by the ITU in May - in its R&D laboratories.

Why 2025 Will Redefine Mobile Connectivity

As international travel rebounds to pre-pandemic levels in 2025, the mobile communication roaming market is at an inflection point. Emerging technologies and changing customer preferences are challenging traditional wholesale roaming agreements between mobile network operators (MNOs). The global wholesale roaming market is projected to more than double, from $9 billion in 2024 to $20 billion by 2028. This surge will be fueled by the expanding deployment of 5G Standalone (SA) technology, which enables real-time roaming connections and activity monitoring. But beneath this headline figure lies a complex landscape of regional variations and technological mobile service disruptions. Global Mobile Roaming Market Development Western Europe dominates inbound roaming connections, largely thanks to its Roam Like at Home (RLAH) initiative, which eliminates roaming charges among member countries.  Meanwhile, the Indian Subcontinent is emerging as a growth hotspot. Between 2024 and 2029, inbou...
