Mobile broadband speeds could hit a blistering 42Mb/sec as early as next year, according to Ericsson's chief technology officer.
The idea seems far-fetched given that even the fastest dongles currently hover at around 7.2Mb/sec, but according to John Cunliffe, the technology to smash that barrier is just around the corner.
"If you look at what's actually happening, the fastest service in the UK at the moment is 7.2Mb/sec, but we can easily see how we get to 14Mb/sec by improving the codes using the modulation," he tells PC Pro. "After that there are two steps that can boost speed..”

Researchers at Siemens Corporate Technology have succeeded in transmitting data at a rate of one gigabit per second through optical polymer fibre cables, setting a new record.
A new data transmission technique allowed the fast rate, which is ten times faster than with products currently on the market. This performance sets the stage for the use of polymer cables in home entertainment and factory automation.
In polymer fibre cable transmission, small converter boxes convert the electrical signal from the copper cable into an optical signal and thin plastic cables transport the optical signal to receivers. Because of the very high transmission rate of these polymer fibre cables, television signals with high data volumes could also be transmitted within the home in this way in the future.

The University of Wisconsin-Madison has launched a new research network which is up to 20,000 times faster and one million times the capacity of a typical home broadband connection.
The Broadband Optical Research, Education and Sciences Network (or BOREAS-Net), forms a loop of fibre optic cable between UW-Madison, Iowa State University, the University of Iowa, and the University of Minnesota. It features two links to Internet2, at Chicago and Kansas City, Missouri. Any outage anywhere in the loop is essentially unnoticed as traffic is rerouted at the speed of light to the other access point.

Siemens and Infineon have developed a simple broadband transmission system for use in home networks. The system uses optical polymer cables that can be laid and installed without requiring any special skills.
As is the case with fiber optics, the new system uses light waves to transmit data. Today’s optical transmission technology can easily maintain a constant data transmission rate of 100 megabits per second (Mbit/s), making it suited for Internet TV, HDTVs and video-on-demand.
The picture quality is just as good as with copper wires. Because plastic cables are unaffected by electromagnetic waves, electrical devices in the vicinity do not interfere with the data flow. Since the polymer cables are only about 1.5 millimeters thick, they can easily be laid underneath carpets, for example. The data cables are easy to install: Users merely have to measure the desired length, cut the cables with the tool that is supplied and stick the ends into the appropriate sockets. Plugs are therefore not required.

In cooperation with Micram, the Fraunhofer Institute for Telecommunications (Heinrich-Hertz-Institut) and Eindhoven Technical University, Siemens has successfully tested the network of the future. This involved the 100% electrical processing of data rates of 107 Gbits per second and transmission over a 100 mile long fiber-optic route in the U.S. – the first time this has ever been done outside the laboratory.
The record performance was made possible by a newly developed transmission and receiving system that processes the data by purely electrical means directly before and after its conversion into optical signals. The test was conducted at a long-haul network at one of world’s largest optical network operators, in which Siemens has previously deployed a 40 Gbits per second optical network for commercial use.
Ultra-high bandwidth capacity in core network will be required to cater the traffic generated by online games, music, and video downloads. By 2011, legal music downloads alone will account for 36 percent of the entire music business in Europe according to market research institute Forrester Research.
