Bell Atlantic Corp, Nynex Corp and CAI Wireless Systems Inc have suspended their 1995 agreement to develop wireless video networks – but only for one year, Bell Atlantic said. It said that this clears way for CAI to develop its Multichannel Multipoint Distribution Service transport systems better – but under a new agreement, CAI also has the option to buy back the $100m investment in CAI securities made by Bell Atlantic and Nynex.
