US cable company Comcast is planning to cut jobs as part of plans to centralize operations and boost its broadband business.

Reuters reported last week that the cuts will impact jobs at the company's biggest unit, which covers its Xfinity Internet, mobile, and pay television business.

The layoffs are expected to begin in January, with Comcast set to remove a layer between the corporate and regional offices, in a move that will streamline the management of the unit.

The number of jobs expected to be cut wasn't reported, nor were the specific roles. Reuters reports that customer service and retail roles won't be impacted.

Comcast will also eliminate some divisions as part of the restructure. At present, the company has a three-tier management structure that sees regional teams report to division heads, who then serve as the link to corporate headquarters.

The rejig will see regional leaders report directly to a new executive overseeing operations nationwide, as reported by Reuters, which cites a memo that was sent to employees.

Comcast's cable unit, called Connectivity & Platforms, is one such unit that will become more centralized next year.

"This new model will strengthen the connection between our regions and our HQ functional teams – balancing the benefits of national scale with the insights and execution that come from local leadership,” Comcast Connectivity & Platforms COO Steve Croney and CEO David Watson wrote in a joint memo, as reported by Light Reading.

"This change is not a reflection of anyone's contributions — it is about simplifying how we work so we can compete more effectively," according to the memo.

Comcast has suffered subscriber losses in the broadband market to rivals such as AT&T, Verizon, and T-Mobile.

Despite losing broadband subscribers, the company's Xfinity Mobile unit has performed well, adding a record 378,000 mobile lines in Q2.
