Voice quality solutions provider Ditech Networks today announced that 16 mobile carriers in North America, South America, Europe, Asia and the Middle East -- many of them Tier 1 operators -- are benefiting from “audits” done to their voice networks using Ditech’s Experience Intelligence (EXi) solution, which is used for identifying voice quality problems caused by the caller’s environment and by the mobile devices themselves.
The data collected from the all-software network monitoring solution can now be used by these mobile carriers to identify sources of noise and interference on the caller’s end, which can have the effect of degrading signal quality, and take corrective action to prevent these problems from continuing.
Ditech’s technology employs a broad suite of standards-based codecs which can be used for addressing a wide range of voice network signal quality issues. The company claims its EXi solution, which is used to assess voice quality, “is the industry's only technology that quantifies voice quality problems caused by the caller's environment and by mobile devices.” The EXi solution is intended to augment network quality assessment solutions that measure signal quality on the network itself (in other words, not including external noise factors picked up by the user’s handset, and other noise which is created by the internal components of the handset itself, including the radio(s)). The software application assesses voice quality on live mobile calls to derive an R-Factor and a Mean Opinion Score (MOS). This data can then be combined with other test data derived from other network monitoring solutions to gain a more comprehensive picture of the overall user experience. The test and monitoring software can do this without taxing or putting additional strain on network resources.
"Ditech's EXi solution is gaining momentum in the market as an important complement to existing drive tests, surveys and network monitoring systems," said Todd Simpson, President and CEO of Ditech Networks, in a press release. "EXi remains the industry's only technology to quantify the impact of the caller's environment and mobile devices on call quality."
EXi uses the International Telecommunications Union (ITU) G.107 E-Model as its benchmark for assessing voice quality. The E-Model enables carriers to assess information captured unobtrusively from millions of live mobile calls in real-time.
"Although the E Model has been available in the industry for several years, Ditech Networks is a leader in its implementation for voice quality impairments that are external to the network," said Jessy Cavazos, an analyst at Frost & Sullivan who focuses on the communication test equipment and system industry. "The E Model provides an important new Key Performance Index (KPI) for service providers as they track the impact of voice quality on the subscriber's call experience."
Ditech Networks last made news on ContactCenterSolutions in November when it announced that Orascom Telecom had completed full deployment of Ditech’s products in its Djezzy GSM
mobile services network in Algeria. In addition to using Ditech’s Voice Quality Assurance (VQA) solution, Orascom also reportedly undertook an audit of its network using EXi. Call data was monitored and analyzed over a four-week period, and it was evident that VQA increased Djezzy’s MOS value (Mean Opinion Score) up to a full half-point. Chief Operation Officer of Djezzy Nagi Abboud said that a 0.5 improvement in MOS is significant and will result in a measurable decline in subscriber churn.
Ditech's VQA solution proactively reduces and removes voice quality impairments, including ambient noise, echo and mismatched speech levels. Subscribers thus have a consistent, high-quality call experience no matter where they are located, or in what environment they are making the call.
