Amazon launches AWS Telco Network Builder

Amazon introduced AWS Telco Network Builder, a fully managed network automation service that enables CSPs to deploy, run, and scale their telco networks on AWS faster and more easily. 

To start, a CSP populates their network architecture (e.g., routing requirements, location of deployment, specific NFs) as a template in the service’s console using telecom industry standard language, making it intuitive and easy to begin. AWS Telco Network Builder translates the customer’s network specifications into a cloud-based network architecture, streamlining programming requirements across multiple software vendors and accounting for the network’s geographic footprint. 

AWS Telco Network Builder automatically maps the provided topology to network services, provisions the necessary compute and storage resources, and connects the NFs to create an operational telco network. Customers can then reuse the uploaded templates to replicate that network architecture in new regions. As customers change their network configuration or run software updates, AWS Telco Network Builder handles lifecycle management for the NFs, performs updates to the NFs, and adjusts related infrastructure. 

Together, AWS Telco Network Builder and Amazon CloudWatch provide a comprehensive view of the NFs and AWS infrastructure, so customers can efficiently monitor and manage their networks to identify and remediate issues more quickly. AWS Telco Network Builder also integrates with popular third-party, end-to-end orchestrators for CSPs to maintain continuity across existing telco network operations and business systems. With AWS Telco Network Builder, customers only pay for the AWS products and services they use, so they can quickly scale their network based on business requirements.

“The telecom industry is undergoing a transformation as CSPs navigate building their telco networks in the cloud,” said Jan Hofmeyr, vice president of Amazon Elastic Compute Cloud (Amazon EC2). “Some of the biggest challenges CSPs face as they look to migrate include manually configuring and then managing these complex networks, which impedes growth and stifles innovation. Groundbreaking in the value it provides to the telecom industry, AWS Telco Network Builder removes the burden of translating a customer’s desired telco network into a cloud architecture, empowering them to easily modernize and quickly scale to meet demand while freeing time and capital to build new offerings, expand coverage, and refocus on invention.”

AWS Telco Network Builder is generally available today in US East (N. Virginia), US West (Oregon), Asia Pacific (Sydney), Europe (Frankfurt), and Europe (Paris), and with availability in additional AWS Regions coming soon.

AWS also announced a number of customers and partners using AWS Telco Network Builder, including: Amdocs, Cloudify, Infosys, Mavenir, and O2 Telefónica.

Blueprint: Brazil looks to municipal Wi-Fi 6E

 by Atul Bhatnagar, president and CEO of Cambium Networks

Given its immense size and bountiful natural resources, Brazilians have long talked about their country as the “land of the future.” One unexpected area where Brazil is indeed taking the lead over the rest of the world is in the realm of Wi-Fi connectivity.

In December, Brazil became the first country in Latin America to test outdoor Wi-Fi 6E as part of a joint project in cooperation with the Municipality of São Paulo and the Campo Belo Gastronomia Association, and the results of the test will be eagerly monitored by service providers around the world. 

With the deployment of Wi-Fi 6E in the Campo Belo neighborhood of São Paulo, users are able to take advantage of the faster speeds and lower latencies than were available through Wi-Fi 6 and earlier iterations. In fact, this deployment delivers 10X the capacity of traditional Wi-Fi.  

This is a watershed moment for the spread of advanced broadband. For Brazil and other early adopters, Wi-Fi 6E finally puts the prospect of realizing multi-Gigabit speeds with a 6 GHz fixed wireless infrastructure within reach as Wi-Fi 6E extends the capacity, efficiency, coverage, and performance benefits of advanced Wi-Fi into the 6-GHz band, which allows for internet speeds of greater than 1Gbps.

While the United States approved the 6 GHz spectrum for Wi-Fi use in 2020, a decision that allowed the development and deployment of Wi-Fi 6E devices to move forward, this marks the first real-world study of its use. The insights these tests could provide around the true efficiency and data throughput of these congestion-free connections could prove substantial for others considering the spectrum.

Many service providers in the U.S. have been testing new 6 GHz equipment under experimental licenses granted by the FCC for the purposes of technical evaluation but not for commercial deployment. The outdoor network in São Paulo will now serve as a petri dish for the country to help officials in the U.S. and abroad better understand the benefits this Wi-Fi 6 technology provides and hopefully move us one step closer to a 6 GHz reality.  

This is a particularly exciting moment when you consider the potential impact of advanced internet technology on closing the digital divide for underserved communities around the world and, in this case, the daily life in Brazil, where about 50% of homes are still not connected to broadband. More broadly speaking, these and other multi-Gigabit wireless technologies entering the market will allow providers in the US and around the world to bring fast broadband to more people than ever before.
