EC/IST FP6 Project No 026920 Work Package: 6 Type of document: Report Date: 20.12.2007 File name: OP_WP6_D37_V1.0.doc Version: 1.0 Title: Worldwide Market Research Report 220 / 356 The service should offer anyone in Johannesburg access to the World Wide Web, VOIP telephony, television and radio over IP, video-on-demand, e-government services, free Internet zones and virtual private networks. The network will cater also for the city's surveillance needs, help with traffic management, provide the backbone for commercial display systems, assist local government mobile workers, and bring the city in line with 2010's technology requirements. The city is not prescriptive about what technology is to be used by the successful bidder. "It could be Wi-Fi, Wi-MAX, fibre or powerline broadband," Zimu (the vice-president of the operations group at City Power) told, adding: "but it must be true broadband - we're talking about speeds of over 2Mbps". "It has to be future-proof and scalable. We don't want to have to forklift the solution after five years", he emphasised. "It would be good to see a series of experiments running in the city - it is the duty of government to experiment with different (broadband) technologies". Terblanche (manager consulting) is of the opinion that different technologies may well be used in tandem: powerline broadband has the advantage of being able to run over existing city-owned infrastructure; however, wireless solutions have flexibility in terms of access. The user could be literally anywhere in Joburg and its surrounds and connect. Zimu agrees this scenario of complementary methods is possible, saying that wireline, powerline and wireless all "seek to meet and fulfil the same need for broadband connectivity". "With powerline broadband, don't forget that you can have nomadic connectivity. You can plug in and access the Internet from wherever", he says. In this context, the powerline communications seem to have good possibilities of employment (at least in conjunction with other technologies) in a great and modern city as Johannesburg. To appraise this possibility, a Broadband over Power Lines (BPL) has been launched in the Alexandria Township North of Johannesburg, involving 183 households. All these projects and investments, are contributing also to the birth of new telecoms operators that should integrate themselves in the coverage of the territory or to increase the competition inside the market, in advantage of the end users: one of these operators is, for

Nevertheless also here, interest in powerline communication is strong. The electric grid of Ghana is sufficiently expanded and however, it is more extended than that telephonic network. From here the interest, very strong, in the PLC technology, more than for the wireless one, still too much expensive. Tests are still to the initial stadium, directs above all to show that the powerline communication is also possible and feasible in Ghana. [A18] Africa's first powerline implementation took a step nearer with a demonstration given in Ghana to a number of key players, including the Electricity Corporation of Ghana. Although there are now a number of implementations in the developed world, it remains a technology that has to prove itself. Cactel Communications (formerly Intell Solutions) demonstrated a small-scale installation and has plans for a much larger pilot. In broad terms, there are two types of powerline solutions: one uses medium sub-station technology (33kv) and the other low-voltage sub-stations (11kv). In terms of a capital city like Accra, it has about 29 medium-voltage sub-stations and around 100 low-voltage sub- stations. Cactel's Boye claims that the technology solution offered by its partners for deployment in medium-voltage sub-stations is 70% cheaper than anything offered for deployment in low-voltage sub-stations. Deployment is carried out by switching off the sub-station and attaching an auxiliary cable from a coupling unit to a high-speed modem. This allows the bandwidth signal to pass through the same cable as the power it also carries. A medium-voltage sub-station has a 3 kilometre range but this can be extended by deploying what is called a Home Gateway which includes a modem and repeater to boost the signal strength.
