Before joining Dell in 1993, Ms. Sheskey held key planning, development and operational roles at Ameritech Corporate, Ameritech Services and Ohio Bell.
The first 1G network launched in the USA was Chicago-based Ameritech in 1983 using the Motorola DynaTAC mobile phone.
A few of the systems they broke into include those of United States Army, the White House, United States Cellular, Ameritech and the US Postal Service.
On October 13, 1983, David D Meilahn placed the first commercial wireless call on a DynaTAC from his 1983 Mercedes 380SL to Bob Barnett, former president of Ameritech Mobile Communications, who then placed a call on a DynaTAC from inside a Chrysler convertible to the grandson of Alexander Graham Bell who was in Germany for the event.
Richard Notebaert, who had led Ameritech, the Midwestern AT&T spin-off until it was acquired by SBC in 1999, took over Tellabs as CEO in September 2000.
