Instead of your regular 4G hotspot speeds, Comcast is throttling these to a measly 600Kbps.
For customers on either By the Gig or Unlimited plan: speeds for streaming video will be cut down to 480p resolution. Some of Verizon's and AT&T's unlimited plans include resolution throttling to 480p. This will be a free "upgrade" for a short period of time - Xfinity Mobile is going to start charging an unknown fee for the 720p streaming resolution upgrade later this year.
As it now stands, videos you stream using your Xfinity Mobile data are presented in 720p HD.
"We're making two changes to our service to help us maintain the low price point of Xfinity Mobile", the carrier explained in a statement to FierceWireless.
Comcast notified users that it is introducing some Xfinity Mobile throttling. For now, customers can contact Comcast for an "upgrade" to 720p video "on an interim basis at no charge".
The Wireless industry is an ever-changing world where big ideas come along daily. All Xfinity Mobile customers are receiving this email, Comcast confirmed to Ars. "Our By the Gig data option will continue to deliver 4G speeds for all data traffic", said Comcast. For those who are unaware, Xfinity Mobile is the MVNO that's available exclusively to Comcast's home internet customers and runs on Verizon's network.
Xfinity Mobile, a Mobile Virtual Network Operator owned by Comcast, has announced new restrictions on video quality and hotspot speeds. Second, we're setting personal hotspotting at 3G speeds for all Unlimited customers, which will allow customers to continue to do numerous things they enjoy doing online. The change will only apply when customers are streaming video over cellular data, an important distinction since one of the benefits of Xfinity Mobile is the ability to automatically connect to the company's huge network of Wi-Fi hot spots. The company says this will allow those paying "By the Gig" to save money, as well as keeping those on the unlimited plan further from the 20GB threshold after which the speed is throttled.
