Sprint Nextel Corp., a provider of wireline and wireless communications, said today it has just invested $35 million in enhancements to both the Sprint PCS Nationwide Network and the Nextel National Network in the Boston area.

The upgrades are a result of additional wireless cell sites and equipment that add coverage and network capacity, the company said.

Among the neighborhoods and communities that should benefit from improvements to the Sprint PCS Network are Framingham, Quincy, Roxbury, and Somerville.
