Plugged In: Broadband over Power Lines


In mid February 2011 the Institute of Electrical and Electronics Engineers (IEEE) published a new standard for data transmission using electricity lines. This technology has potential to convert the electricity grid into one large high speed IP network.

Networking products that fully comply with IEEE 1901 will deliver data rates in excess of 500 Mbps in LAN applications. In first-mile/last-mile applications, IEEE 1901-compliant devices will achieve ranges of up to 1,500 meters. The technology specified by IEEE 1901 uses sophisticated modulation techniques to transmit data over standard AC power lines of any voltage at transmission frequencies of less than 100 MHz.

In the transportation sector, for example, the standard’s data rates and range make it possible to deliver A/V entertainment to the seats of airplanes, trains and other mass transit vehicles. Electric vehicles can download a new entertainment playlist to the A/V system while the car is charging overnight.

In the home, [power-line communication] will complement wireless LANs by providing a link through walls and other RF impediments as well as over distances beyond the normal range of wireless networks. It will complement wireless networks in hotels and other multi-story buildings by carrying multimedia data over the longer distances and allowing wireless to complete the communication link over the last few meters.


Electricity distributors have a golden opportunity to provide data and voice services without laying a single stand of wire. Will they seize the opportunity?

Whose Shilling?

Zimbabwe is Africa's Lazarus. The economy is in tatters, the citizenry of this great nation are despondent but Robert Gabriel Mugabe remains firmly in charge. For the time being. Many believe that only South Africa is in a position to determine the destiny of Zimbabwe. Yet President Thabo Mbeki, save for his quiet diplomacy, appears disinterested in employing enough downward pressure for Mr. Mugabe to repent his sins and thereby rid the Zimbabweans of their current economic woes. What exactly does Mr Mugabe have on Mbeki? In exile Mbeki lived, at different times, in the United Kingdom, Botswana and Zambia. He hardly was guest of the Mugabe's. On that score alone, Mbeki does not owe Robert a good turn. Of the two neighbours, Zimbabwe is most reliant on the other. Zimbabwe relies on South Africa's ports for her exports and imports. She draws electricity and routes her telecommunication traffic through her southern neighbour. South Africa is one of Zimbabwe's m

Free mobile-to-mobile calls

A mobile phone is a miniature telephone exchange. It accepts incoming calls, initiates outgoing calls and can act as a repeater by forwarding calls or as a switch through teleconferencing. These are the basic features of a telephone exchange. TerraNet , a Swedish firm, has exploited these features to facilitate free mobile-to-mobile calls. Using peer-to-peer technology, a cluster of mobile phones can communicate without the need to go through a base station (switch) provided they are within 1,000m of each other. This technology, being trialled in Ecuador and Tanzania, is perfect for developing countries where infrastructure is as limited as disposable income. Because mobile phones can forward calls, the effective communication distance can be extended from a 1 kilometer radius to about 20 kilometers. That is sufficient to cover most rural communities and, for example, university campuses. Like Skype , this is a subvertive, effective and disruptive technology. While manufacturers

Want to test midlets on real phones?

Most mobile phone manufacturers offer emulators to help developers with software tests. Java and C++ programming environments usually provide plug-in facilities for emulators . Products such as Pulsar go a step further to integrate and maintain the entire development space. Although emulators catch a fair amount of design and runtime errors, software behaviour on real phones is unpredictable. For most developers it is not financially feasible to test the behaviour of their mobile applications on all target platforms. To get around this obstacle some companies offer on-line services that allow for application testing on real devices. These services are often expensive. In software provided by phone manufacturers multiple instances of the emulator are invoked to simulate the behaviour of federated handsets. One solution is to run an instance of the application on a PC and set up a local communication channel with a real phone. A neat, inexpensive and elegant solution is availab
