Shaw Communications has unleashed a new cable modem service tier that caps the downstream at 25 Mbps, but limits the upstream to 1 Mbps.
Shaw started taking orders for the new "Nitro" tier on Nov. 15 from customers in Calgary, Edmonton, Saskatoon, Winnipeg, Vancouver and Victoria. Nitro will sell for $99.95 per month when customers purchase the modem.
In addition to a speedier cap, the new level of service also features 10 private e-mail addresses, 20 megabytes of personal Web space, two IP addresses, and a security software and services package.
Shaw is also continuing its practice of using consumption caps. Customers who sign on for the Nitro service are limited to 150 gigabytes per month.
"The addition of High-Speed Nitro to our Internet service line-up is testament to how we listen to our customers. They were asking for more speed, and now the fastest is even faster," said Shaw President Peter Bissonnette, in a statement.
Nitro marks Shaw's fourth cable modem service tier. Its "Xtreme-I" level is capped at 10 Mbps in the downstream for $48.95 per month (with purchased modem).
Likewise, its flagship 5 Mbps "High-Speed Internet" sells for $38.95 per month, and its 256 kbps "Lite" tier goes for $24.95 per month.
Although cable's upstream remains relatively limited unless it supports DOCSIS 2.0 at the modem and cable modem termination system (CMTS) level, the cable industry is also working on DOCSIS 3.0, a new set of specs that enables operators to bond together multiple 6 MHz channels and boost speeds in both directions. Earlier this year, Shaw said it is committed to deploying DOCSIS 3.0 "as quickly as possible."
