AT&T Corp. is testing technology in Waukesha that might reduce the number of dropped cellphone calls, reported the Milwaukee Journal Sentinel.
The company has already been testing transmitters on its Waukesha campus that has a customer call center and other services.
The tested technology would be placed in areas where large cell tower don'g work and mounted on lampposts, utility poles and buildings.
It's a big step toward filling coverage gaps in areas where a wireless signal is blocked by buildings, reported the Journal Sentinel.
Similar technology is used in large places like sports stadiums, including Miller Park. AT&T says it plans to install more than 40,000 small cell transmitters on its wireless network by the end of 2015.
AT&T spokesman Jim Greer told the Journal Sentinel that there's been significant improvement in coverage at the Waukesha test site.
Tests are also being done in Crystal Lake Park, Mo., a suburb of St. Louis.
