Calhoun Communications Relocates to Sioux City
Technology Enables Buildings to Talk to Buildings

SIOUX CITY, IOWA February 23, 2007 — Calhoun Communications, one of the top integrators of wireless networking and radio broadcasting solutions, announces the grand opening of its new office location in the Benson Building at 705 Douglas St. The Siouxland Chamber of Commerce will host a ribbon-cutting ceremony and open house in Suite 540 on Tuesday, February 27th from 4:30 p.m. to 6:30 p.m.

“We’re thrilled to be a part of the Sioux City business community,” remarked Gerald Calhoun, company founder and president. “We’ve been in business for over 30 years and our move brings eleven new jobs to downtown. We plan on making Sioux City our permanent home.”

Calhoun Communications designs wireless wide-area networks (WANs) for government, schools, businesses, hotels, conventions facilities and complex municipalities. The company also provides quality equipment, service and support for television and radio broadcasting, local area networks (LANs) and off-site data backup services for its clients.

“Our newly renovated location gives us professional office facilities and makes working with some of our existing customers much more convenient,” Calhoun noted.

One of those customers is Woodbury County itself, for whom Calhoun installed three microwave links last summer. This project enables those remote areas to access the Starcomm interoperability system linking public safety institutions in Woodbury, Dakota (NE) and Union (SD) counties.

The City of Huron, South Dakota also contracted with the company earlier this year to develop and install a mobile network solution that provides high-speed network connectivity to police officers on patrol.

Calhoun Communications installed and implemented an extensive high-speed wireless network project for the Woodbury County Information and Communication Commission (WCICC). That system enables various city and county facilities all over the Sioux City area to communicate across a high speed data network using the wireless technology. This minimized and/o eliminated recurring monthly lease costs for traditional copper type connections.

The company has also been retained to provide updates and maintenance for these systems.
