The deal, subject to court approval in the U.S. and Canada, will greatly expand Ericsson's foothold in North America, bringing customer relationships with large operators such as Verizon and Sprint.

Nortel had been operating under court bankruptcy protection since January. In June, the company accepted a $650 million offer from Nokia Siemens Networks for its CDMA and LTE assets. That offer set the stage for Private equity firm MatlinPatterson to jump in with a counter offer of $725 million for the wireless assets.

Research in Motion also made an offer for the assets but was barred from the sale after a bidding procedure dispute with Nortel.

Ericsson was a late entrant to the bidding process, with its interest publicly declared just Thursday. As part of deal, announced early Saturday, Ericsson will offer employment to a minimum of 2,500 Nortel employees supporting the CDMA and LTE Access business.

"This is one of those gifts from heaven for Ericsson in the otherwise very competitive world these companies operate in. Rather than competing with Nortel, Ericsson has won," said telecom industry analyst Jeff Kagan in e-mail. The consolidation of the industry, however, is not necessarily a good thing for customers, he noted.
