According to Paulo Ribeiro, Director, Engineering for NOS “Our partnership with OpenVault is helping us deliver the best possible experience to our broadband customers by adapting the configuration to the field conditions, dramatically improving higher connections speeds for many of our subscribers and significantly increasing network capacity.”
“NOS has been a leader since Day One in recognizing how PMA can improve network capacity and resiliency,” said Tony Costa, CTO of OpenVault. “Their expertise, their collaborative approach, and their focus on achieving optimal subscriber experiences all helped us streamline deployment that ultimately will result in greater subscriber satisfaction.”
PMA was developed to leverage the programmable PHY layer to increase the usable capacity in DOCSIS 3.1 networks. The goal of PMA is to optimize the amount of data that can be transferred on an OFDM(A) channel in a given amount of time based on real-world impaired plant conditions.
OpenVault’s OV PMA optimizes modulation profiles used by DOCSIS 3.1 cable modems on OFDM(A) channels. It then routinely monitors and adjusts these profiles to ensure that subscribers receive the best possible service quality. This results in improvement of up to 40 percent in overall network capacity and bolsters the resilience of DOCSIS 3.1 modems, particularly in the presence of impairments.
