Verizon's recent purchases of two vehicle tracking firms could spark more deals as the No. 1 wireless provider and rival AT&T see fleet management as a source of growth, NBCnews analysts said.

Faced with a saturated wireless market, several telecom companies are looking beyond their main phone business for ways to extract more value from existing networks. Just last month, Verizon bought Yahoo for $4.8 billion, diving into digital media and advertising.

But Verizon also recently acquired privately held connected-vehicle technology firm Telogis for an undisclosed sum and said it would buy GPS vehicle tracking company Fleetmatics for $2.4 billion.

Telecom providers are moving towards acquiring "eyeballs or a fleet of people" that can use applications built on top of the wireless network, said Richard McBee, chief executive officer of Canadian communications technology company Mitel Networks.

The fleet and mobile workforce management business connects fleet vehicles to the wireless network and collects data, like driver behavior, to manage vehicles and workers. The business delivers a source of recurring subscription-based revenue from clients such as large logistics companies and local delivery services.

Rival AT&T has its own fleet management business and could look into buying fleet tracking firms such as Teletrac Navman, Omnitracs, Geotab and Zonar, analysts said.

Verizon, Argus, Movimento, AT&T, Omnitracs and Zonar Systems declined to comment. Teletrac Navman and Geotab could not be immediately reached for comment.
