BARCELONA -- MWC -- Today at Mobile World Congress, Facebook is announcing a number of new initiatives with partners to upgrade existing networks for the future, build new networks in under-connected regions, and leverage new technologies, tools, and programs to bring more people online.

These initiatives include partnerships to support Terragraph, a millimeter-wave, multi-node wireless backhaul system optimized to bring high-speed internet connectivity to dense urban areas. Facebook also is announcing new partner trials for OpenCellular, a low-power base station optimized for rural and traditionally underdeveloped regions of the world, among other announcements.

In addition, the Telecom Infra Project (TIP) — launched two years ago by Facebook and a number of industry partners to collaborate on new technologies to accelerate the pace of innovation in network infrastructure and to bring more people online — has grown to more than 500 companies and also is announcing new progress from project groups.

Over the past year, there have been encouraging gains in connectivity worldwide. The newest edition of Facebook's Inclusive Internet Index, being released today by the Economist Intelligence Unit, finds that Internet access grew by 8.3% over the past year. Yet with billions of people still not online worldwide, there is much more to do. Facebook remains committed to working closely with the telecommunications ecosystem to help connect the 3.8 billion people who are not yet online and improve the experiences of those already connected.

Upgrading existing networks for the future

Facebook has completed the initial engineering validation of our Terragraph technology, and is excited to enter the next phase of development by learning with partners in the field. Terragraph will be deployed into field trials in two locations serving customer traffic. Deutsche Telekom is actively evaluating millimeter-wave technology use across Europe. Magyar Telekom, the largest Hungarian telecommunications company and a subsidiary of Deutsche Telekom, is planning to deploy a Terragraph field trial in the Budapest area. We are also partnering with Telenor to conduct a Terragraph production field trial in Kuala Lumpur.

Together with Deutsche Telekom, Facebook contributed some of the Terragraph learnings around cost-economics modeling, network planning, technical validation, and deployment best practices through the TIP mmWave Networks project group.

Facebook is excited to partner with the technology ecosystem to develop interoperable commercial solutions based on Terragraph. Nokia is announcing gigabit broadband trials that will combine its Wireless PON with Terragraph’s TDMA scheduling capabilities to launch Terragraph-certified solutions. In addition, we collaborated with both Intel and Radwin to deliver a reference design for Terragraph-certified 60 GHz solutions for service providers based on the Intel architecture.

Facebook also is building new tools to support faster deployments of future millimeter-wave technologies, including but not limited to Terragraph. Technologies utilizing millimeter-wave frequencies require precise line-of-sight planning to avoid interference. To address these challenges, we are leveraging computer vision and network optimization models to identify which street furniture — city infrastructure such as traffic lights and stop signs — can be used to deploy these new networks.

Building networks in under-connected regions

Last year, Facebook announced a partnership with Telefonica to extend mobile coverage in rural areas of Peru using new technologies and a new operating model. Today, Facebook and Telefonica announced the completion of initial deployments of high-speed mobile internet to tens of thousands of Peruvians across the highlands and in the Amazonian rainforest, as well as our commitment to expanding this rural connectivity collaboration into more countries in Latin America.

Recently, the team began testing the ability to stretch the capabilities of existing technologies to connect remote communities in Peru with 3G and 4G wireless based on general-purpose processing platforms. Telefonica also plans to test Facebook's OpenCellular LTE RAN platform. Facebook and Telefonica today announced the companies' commitment to expand this collaboration beyond Peru, with a focus on rural and semi-urban connectivity.

The new operating model takes an open approach to network deployment by empowering rural mobile infrastructure operators, local entrepreneurs, and communities to collaborate in delivering high-quality connectivity efficiently and sustainably. Facebook's work with Telefonica in Peru provided invaluable insights into the importance of complementary connectivity policies, especially for rural areas, and today, Facebook published a joint policy paper with Telefonica, New Approach to Rural Connectivity: The Case for Peru that discusses ways policies can help improve connectivity.

Facebook is also announcing that it plans to launch an initiative with Orange to focus on connecting the unconnected and improving connectivity for this group in Africa by concentrating on using new tech and approaches for better access and backhaul networks. The company looks forward to collaborating with Orange to make progress in bringing more people online.

New technologies, tools, and programs to bring more people online

Facebook also is trialing technologies that were built to address some of the challenges associated with deployments in traditionally difficult-to-connect regions. Today, Facebook announces a joint trial with BT, Nokia, and Cavium to demonstrate interoperability between the OpenCellular platform and the Nokia community hosted network, enabling cloud-based remote auto-connection, configuration and monitoring of the Open Cellular base station. This solution will initially be trialed in remote rural communities in the Highlands and Islands of Scotland.

Separately, Vodacom announced a trial of OpenCellular in Africa, and Telenor announced it will be conducting an OpenCellular trial in Pakistan.

In addition, to accelerate network deployments, Facebook is building better tools and technologies. For example, the company is helping operators accurately gauge where demand for connectivity exists through machine learning–optimized population density maps to identify human-built structures from satellite imagery. Facebook is also leveraging data science methods to help optimize backhaul and access connectivity routes to connect the maximum number of people in an economically sustainable way.

Finally, Facebook is collaborating on additional efforts to expand connectivity, including partnerships focused on backhaul infrastructure and more than 10 Express Wi-Fi partners and 85 Free Basics partners worldwide. In addition, the company is working with partners in unconnected and under-connected regions to explore new business models and technologies for deployments, share learnings and best practices from these deployments, and create data science tools to supplement existing network planning methodologies.

A CSP's digital transformation involves so much more than technology. Crucial – and often most challenging – is the cultural transformation that goes along with it. As Sigma's Chief Technology Officer, Catherine Michel has extensive experience with technology as she leads the company's entire product portfolio and strategy. But she's also no stranger to merging technology and culture, having taken a company — Tribold — from inception to acquisition (by Sigma in 2013), and she continues to advise service providers on how to drive their own transformations. This impressive female leader and vocal advocate for other women in the industry will join Women in Comms for a live radio show to discuss all things digital transformation, including the cultural transformation that goes along with it.
