In Chicago, the A block cellular carrier was originally Rogers Radio Communications Service, a long-time radio common carrier and Bell competitor. Its network was ultimately acquired by Soutwestern Bell Mobile Services, which was building up a nationwide presence as a nonwireline carrier in markets where it didn't own the telco.
This company became part of SBC, and its licenses were ultimately transferred to Cingular, which SBC co-owns. The B block carrier was originally AT&T's AMPS subsidiary, which transferred the license to Ameritech Mobile as part of the AT&T breakup. When SBC merged with Ameritech, the B block license was divested to GTE, which later became part of Verizon Wireless. So the non-telco A block license is now owned by an affiliate of the telco, and the original telco B block license is now owned by a telco that isn't a telco in Chicago. All clear?
A was originally licensed to the nonwireline company Cybertel, which sold out to Ameritech. B was AT&T/AMPS/Southwestern Bell Mobile Services, the local telco affiliate. The Ameritech license was transferred to GTE and then Verizon Wireless, as in Chicago, when SBC merged with Ameritech, and SBC's license went to Cingular.
Dobson Cellular is affiliated with the Dobson Telephone Company, but it's involved in cellular in rural markets all over.
The Cellular One brand was originally created and owned by the Washington Baltimore Cellular Telephone Co., the Washington/Baltimore A block licensee, which was owned in part by the Washington Post; the name was created for licensing as a common brand name for A block licensees, who didn't have the national brand recognition that the telcos had on the B side. Ironically, Southwestern Bell bought out the Washington Post and, eventually, the other owners of the Washington Baltimore Cellular Telephone Co. It continued to use the Cellular One name for its A block systems, and continued to license its use by others, until it formed Cingular. When it was decided that Cingular would use its own name and not Cellular One, the Cellular One name and licensing rights were sold to Western Wireless, which alredy used the name widely. And now Western Wireless is being acquired by Alltel.
Funny thing about the phone business. Almost every company in the business either started out as a phone company or becomes one.
Michael D. Sullivan Bethesda, MD (USA) (Replace "example.invalid" with "com" in my address.)[TELECOM Digest Editor's Note: I _think_ my original response to Lisa Hancock is still true however. We were discussing VOIP troubles and how cellular phone companies 'never got sued' (in the old days) because of their inability to route 911 correctly. I suggested that rarity of lawsuits may have been a function of their underlying ownership; unlike VOIP, which is coming in cold, the cellular companies all had 'telco' in their family trees somewhere.
