Comdial Launches Air Impact, Expanding In-Building Wireless Product Line; Wireless system lets on-the-go managers stay in touch.

CHARLOTTESVILLE, Va.--(BUSINESS WIRE)--Nov. 3, 1997--Comdial Corporation (NASDAQ NM:CMDL) today announced the introduction of Air Impact, a new multi-cell, in-building wireless communications system that works behind business-telephone switching platforms produced by Comdial and other leading switch manufacturers.

Providing seamless handoff between cells, the Air Impact system accommodates up to 32 cell sites and more than 1,000 wireless handsets. Telephone reception is both clear and secure, as digital encryption assures privacy. Transmission is over the 1.9 Gigahertz personal communications services (PCS) band, dedicated solely to this type of wireless application. Because Air Impact - like all of Comdial's in-building wireless products -- uses unlicensed spectrum, there are no monthly service charges or fees. The lightweight, pocket-sized handset features programmable function keys, volume control, headset jack, internal antenna and an informative LCD.

Designed for use by large retailers, schools, health care facilities, manufacturing companies, and other businesses where employees roam and are often unable to take calls at a desk, Air Impact is available through Comdial's National Accounts sales force. A complete six-user system, including base unit, wireline interface, and handsets with battery packs and charging stands, retails for approximately $6,200.

"In addition to messaging systems, computer-telephone integration software, and Internet telephony, in-building wireless is a strategic growth area that Comdial has targeted to sustain rapid sales and profit growth," said William G. Mustain, Comdial's president and CEO. "The introduction of Air Impact furthers our commitment to capturing a significant share of the fast-growing market for in-building wireless communications systems."

Market projections from Phillips InfoTech Consulting value the market for in-building wireless products at $225 million in 1997, growing rapidly to $935 million in the year 2000.

With the addition of Air Impact to Comdial's family of in-building wireless products, which includes the Tracker integrated pager introduced in 1994 and the Scout single-cell, multi-line wireless phone introduced in 1995, Comdial now offers a product to meet the needs of virtually all in-building wireless users, from small retail shops to large campus environments.

Comdial Corporation is an innovator of wired and wireless telecommunications products and computer-telephone integration solutions for small to medium-sized businesses.
