  • YTL Communications’ 5G mobile network powered by Casa Systems follows up 2022 win with a repeat win in 2023
  • Casa’s LTE network and cloud-native 5G core help YTLC lead Malaysia’s digital transformation
  • Cloud-native architecture featuring control and user plane separation provides unrivaled 5G network performance

ANDOVER, Mass., Oct. 30, 2023 (GLOBE NEWSWIRE) -- Casa Systems (Nasdaq: CASA), provider of cloud native network solutions serving Tier 1 and regional service providers worldwide, today announced that for the second consecutive year, YTL Communications (YTLC), operating its service brand “Yes”, has won the Ookla Speedtest Award for Fastest Mobile Network (All Technologies) in Malaysia. Both YTLC’s 4G and 5G services are powered by Casa Systems’ cloud-native Ayxom™ Core.

Having won the coveted Ookla award back-to-back in 2022 and 2023, YTLC has firmly cemented its leadership position in Malaysia. At a median top speed of 489 Mbps, the Yes 5G network is one of the highest-performing networks globally. 

The exceptional network performance stems from YTLC’s and Casa Systems’ joint commitments to cloud-native network functions virtualization (NFV), which supports control and user plane separation (CUPS) architecture. The separation of the control and user planes provides YTLC greater flexibility, scalability, efficiency and speed in delivering network services nationwide. 

“YTLC’s sustained ability to deliver ground-breaking, award-winning 5G performance to customers in Malaysia provides strong evidence of the value of pairing world-class carrier services with Casa Systems’ cloud-native virtualized network functions,” said Michael Glickman, Chief Executive Officer at Casa Systems. “Earning the Ookla Speedtest Award for Fastest Network in Malaysia in back-to-back years proves that consumers and businesses alike can get the best of what 5G offers when they choose a carrier powered by Casa Systems’ cloud-native 5G core.”

“Our mission is to enable “5G for All”. The cloud-native mobile core we built with Casa Systems enabled us to be the first to launch 5G nationwide – in fact, by 11 months earlier than any other carriers in our market,” said Wing K. Lee, Chief Executive Officer at YTL Communications. “Now, with Ookla’s endorsement for the second year in a row, it has proven that Casa Systems’ leading-edge NFV and cloud-native mobile core have enabled us to achieve our mission by delivering the highest 5G performance while enabling massive adoption with one of the lowest tariffs in the world. It’s clear that our fidelity to cloud-native NFV offerings has structurally optimized our unit cost economics while helping us seize tremendous time-to-market advantage over other carriers in Malaysia.”

YTLC and Casa Systems have been partnering since 2020, with YTLC initially deploying Casa Systems’ 4G mobile core before taking the leadership position to jumpstart Malaysia into the new era of 5G in December 2021. Concurrent with YTLC’s 5G deployment in Malaysia, Casa Systems also entered into a multi-year engagement with Verizon, providing 5G Core Network Functions to power the carrier’s public Mobile Edge Compute (MEC) service offering in the United States.

Ookla is a global leader in fixed broadband and mobile network testing applications, data, and analysis. The Speedtest Awards are based on consumer-initiated tests and background scans from Speedtest applications. They represent real-world network performance and the internet speeds and coverage provided to customers.
