4G carrier Clearwire's chairman Craig McCaw has resigned, prompting speculation that the WiMAX operator is experiencing significant operating issues. According to an SEC filing, McCaw's departure "is not due to any disagreements with the company"; he will be replaced by previous co-chair Ben Wolff.
"Mr. McCaw served as Chairman of the Board of the Company for over 2 years, and served as the Chairman of the Company’s predecessor entity for more than 5 years. Mr. McCaw’s decision to resign is not due to any disagreements with the Company on any matters relating to the Company’s operations, policies, or practices" Clearwire SEC filing
Clear has come under renewed 4G competition in recent months, with Verizon launching its own 4G LTE network and T-Mobile offering high-speed HSPA+. The carrier has recently axed its CLEAR iSpot Apple-centric mobile hotspot, which offered cut-price 4G service to iPad and other Apple device users, but which modders discovered was readily tweaked to support any WiFi-enabled hardware.
