A new microwave system poses threat to cable TV

Article Abstract:

Cellular Vision of New York Inc has developed an ultra-high frequency microwave technology for television broadcasting that was approved by the Federal Communications Commission (FCC). A broadcasting system based on the technology could compete strongly with cable television by offering 49 channels of comparable quality at half the price. Microwave technology was considered unusable for broadcasting because microwaves usually need a direct, unobstructed path, and because high-frequency microwaves cause adjacent channels to interfere with each other. The new technology uses microwaves' ability to bounce off of buildings to provide a viable path, and the company uses carefully aligned cells similar to cellular telephone cells to ensure that microwaves do not overlap. The FCC discussed allocating frequencies for the technology and offering licenses. The technology has not been proven effective in densely populated cities. Cable companies say they are ready for the competition.

Computer maker says flaw in software caused phone disruptions

Article Abstract:

The source of telephone system disruptions that affected an estimated 10 million customers in late Jun and earl Jul 1991 has been traced to a defect in computer code. DSC Communications Corp of Plano, TX has admitted in Congressional testimony that there are bugs in a recent upgrade of the company's software. Sabotage and virus programs had previously been considered as possibilities. The Federal Communications Commission (FCC) is assembling a team to investigate issues relating to telephone network performance and reliability. It is not clear whether the nation's complex communications systems are being adequately tested.
