Cox Communications will cut more than 100 jobs once it shuts down its wireless unit at the end of next month, according to a newspaper story.

The Atlanta Business Chronicle cited an unnamed source that said the job cuts would include engineers, product development managers, and infrastructure designers.

Privately held Cox pulled the plug on selling its 3G wireless service, which is provisioned through Sprint Nextel, in November and also announced that the service would end March 30. Earlier in 2011, Cox announced it had scrapped the build out of its own 3G network, but said it still planned on making its wireless service available across 50 percent of its footprint by year’s end.

“I can’t confirm a number, but it is true that some jobs will be impacted,” Cox spokesman Todd Smith wrote in an e-mail to CED. “As previously announced, our wireless strategy has changed and we must adjust our workforce to align with our new strategy. Our employees have done everything we have asked and for that we are thankful. We are extremely focused on making this transition as easy as possible on our employees.”

Cox hasn’t said how much it spent on its wireless ambitions, but wireless has been a thorn in the cable operator’s side ever since the project was first announced in 2008.

Cox acquired wireless spectrum, which included both 700 MHz and Advanced Wireless Services (AWS) spectrum, from FCC auctions in 2006 and 2008. Cox spent more than $550 million for radio spectrum licenses to support its wireless plans, but the company's development for its wireless network were constantly behind schedule over the past few years.

In December, Cox Communications announced that it was selling its 20 MHz Advanced Wireless Services (AWS) licenses to Verizon Wireless for $315 million.
