I wonder if this will affect TCL's handset roadmap?

The ban affects the high-speed EV-DO and WCDMA network technologies. Carriers that stand to suffer most are Verizon Wireless and Sprint Nextel Corp., which rely heavily on Qualcomm chips.

If upheld, the ban will apply to about 4.2 million phones encompassing 11 models this year, according to Tina Teng, an analyst at iSuppli Corp. research firm. That would represent less than 5 percent of North American phone shipments for the second half of the year, she said.
