V.44 – New Data-Compression Protocol
V.44 is a new data-compression protocol that delivers data rates
10 percent through 120 percent faster than those achieved by the
existing V.42 bis compression protocol.
Faster Browsing
The most popular activity on the Internet is browsing, and this is
where V.44 delivers the greatest improvement over V.42 bis, so
users can enjoy speeds up to 120 percent faster than with the older
protocol. Popular sites such as Amazon.com and eBay use highly
compressible HTML files, so online shopping is faster than ever.
V.44 also increases data throughput for email (by 27 percent),
Word documents (by 21 percent), Power Point files (by 10
percent), and C source files (by 45 percent).
Conexant Intelligent Modem Devices Support V.44
All of Conexant’s host-controlled modems support V.44, as do
some of the company’s new controller-based modems.
