Spanish operators Telefónica and Vodafone Spain have each announced developments to their domestic networks aimed squarely at meeting growing demand for data services.
Incumbent Telefónica has awarded Alcatel-Lucent a contract to deploy a 100G optical network in the northwest, eastern and southern regions of Spain. The equipment vendor will supply dense wavelength division multiplexer (DWDM) equipment with integrated optical transport network switching and aggregation that it says will support increasing data traffic generated by video and cloud applications.
The network will have a capacity of 8.8 Tbps, though Alcatel-Lucent noted the capacity can be extended to 24 Tbps to meet anticipated demand for video services. In addition to enabling Telefónica to improve the capacity of its regional networks, the 100G deployment will improve resiliency, and offers an auto-restore feature based on a GMPLS control plane to boost reliability, Alcatel-Lucent stated.
Roque Lozano, President of Alcatel-Lucent Spain, said the network will transform Telefónica’s domestic network. “Video is becoming an increasing focus for Telefónica in Spain. That means capacity and reliability are critical elements for its nationwide infrastructure.”
Research company Dell’Oro group recently reported that long-haul DWDM sales helped fuel steady growth in the wider WDM market in the second quarter. Revenues for the former grew 18% year on year, while WDM revenues increased a more modest 4%.
Vodafone’s Spanish developments, meanwhile, centre on mobile broadband. The carrier announced it will launch LTE Advanced (LTE-A) services in Madrid, Barcelona and Valencia in October - a move that includes the launch of voice over LTE (VoLTE) services.
The operator states the development will double the data capacity of its LTE network, and enable it to offer mobile data rates of up to 300 Mbps in the downlink. Vodafone Spain is deploying LTE-A in the 1800 MHz and 2600 MHz frequency bands, and said it would add 800 MHz when the band becomes available.
Vodafone Spain said its VoLTE service will connect calls in under a second, and allow users to access services including video calling and streaming, instant messaging, and navigation functions while on the phone. The operator has also lined up an LTE-A compatible
