A vignette that aptly illustrates America's troubled transition from copper to fiber

Jared Mauch, a senior network architect at Akamai in his day job, moved into his house in 2002. At that point, he got a T1 line when 1.5Mbps was "a really great Internet connection," he said. As broadband technology advanced, Mauch expected that an ISP would eventually wire up his house with cable or fiber. It never happened.

He eventually switched to a wireless Internet service provider that delivered about 50Mbps. Mauch at one point contacted Comcast, which told him it would charge $50,000 to extend its cable network to his house. "If they had priced it at $10,000, I would have written them a check," Mauch told Ars. "It was so high at $50,000 that it made me consider if this is worthwhile. Why would I pay them to expand their network if I get nothing back out of it?"

AT&T, the incumbent phone company, finally offered DSL to Mauch about five years ago, he said. However, AT&T's advertised plans for his neighborhood topped out at a measly 1.5Mbps—a good speed in 2002, not in 2020. AT&T stopped offering basic DSL to new customers in October and hasn't upgraded many rural areas to modern replacements, leaving users like Mauch without any great options.

 

This account is not atypical and illustrates how telecom infrastructure bogged down in the transition from analog voice telephone to digital Internet protocol (IP) services, leaving consumers in the lurch. And why cable TV companies can't be expected to fill the gap because they are in the entertainment business and not telecommunications.

Dying on the copper vine: Emerging wireless players face potential backhaul starvation on obsolete T-1s

Wireless broadband, which many see as the solution to fill in the gaps in America's incomplete "hodge podge" wireline telecommunications infrastructure, is itself vulnerable to these same wireline shortcomings, an analysis in Unstrung points out.

The reason, the analysis notes, is wireless broadband remains too dependent on 1970s era T-1 copper data lines for backhaul. T-1's provide far too little bandwidth to support the next generation wireless cell and broadband service known as 4G or Fourth Generation.

The Unstrung analysis also suggests the top tier telcos such as AT&T and Verizon will take advantage of the situation to allow wireless competitors such as Spint, Clearwire and others to literally die on the obsolete copper T-1 vine due to lack of backhaul bandwidth until the big guys get around to updating it with fiber to support their own 4G rollouts.

Bandwidth "currency of the global Internet economy"

Broadband bandwidth is the currency of the global Internet economy and the U.S. is short on funds, Computerworld's Robert L. Mitchell writes.

Twenty years after DSL’s invention, we’re still relying on the same basic technology — and in many areas, providers haven’t even delivered that. Maximum uplink speeds are limited in some locations to as little as 128Kbit/sec., with best-case downlink speeds of 768Kbit/sec.

Next-generation technologies such as Verizon’s FiOS promise metropolitan areas 2Mbit/sec. uplink speeds and 15Mbit/sec. downlink speeds eventually. But Europeans have 20M-30Mbit/sec., and some areas of Korea and Japan have 100Mbit/sec. — enough to support full-motion video. Meanwhile, Gagnon, struggling with basic VoIP, is forced to tell customers to forget DSL and go back to leasing 1960s technology: a T1 line.
