Competition, deregulation, and intervention are all crucial to South Africa's road to a true broadband infrastructure. As of this year, SA had some 67,000 ADSL subscribers. This represents about 0.4% of the worldwide total, and supports the statement that SA remains, and will remain, way behind the rest of the world for a long time to come. Broadband penetration in households varies globally, with Korea being the world leader with a penetration of 68%, the USA having 28%, and the UK 16%. SA shamefully has a broadband household penetration of 0.3%. The question posed here is why South Africa is so far behind... The answer lies not, in the unavailability of the technology, but simply in the pricing. Many people think that Telkom's ADSL solution is one-step closer to a true broadband solution in this country. However, many industry specialists disagree.

Competition is (slowly) bringing down bandwidth costs in South Africa Recently South African cyberspace was given an area code (O87), the country's first report on wireless broadband offerings was released and the cheapest asymmetric digital subscriber line (ADSL) connection was announced. The suffix 087 was allocated for Voice over Internet Protocol (VoIP) numbers by the Independent Communications Authority of South Africa (Icasa), effectively allowing calls routed through the Internet to connect with the traditional tele-coms infrastructure. It would allow users to dial a 087 number much like a cellphone number and connect to someone who also uses a VoIP system instead of Telkom or a cellular network. The call would be routed through a data system, but be answered using a normal telephone or computer, depending on how it is set up b

The idea of a fully 'connected' and integrated digital city, with a plethora of online services for its citizens, sounds ultra-futuristic and like a pipe dream. The local telecoms and IT industry has its own views. The notion of a digital city, where all citizens have access to public services through broadband Internet connections, has long since been in the minds of government and the private sector. The reality is that it is only now that developments in this space are coming to the fore. "The move is about government transforming and all about e-government bringing public services to citizens, but the uptake is slow," says Ashley de Klerk, public sector director at Microsoft SA. Like many others, Zolisa Masiza, councillor at Icasa, asks how the implementation of digital cities can be justified if government has not yet sorted out basic services, such as sanitation, running w

Today's telecommunication arena is rapidly moving towards next-generation networks (NGNs) that offer ubiquitous, converged services over converged voice, video, data and mobile networks. Until very recently, the prevailing telecommunications paradigm was based on multiple types of networks, each serving different types of applications. While IP-related technology holds the most promise for meeting the requirements of NGNs, the use of the global Internet is quite limiting. The IP Multimedia Subsystem (IMS) is an architecture that allows delivery of identical services to fixed and mobile customers - regardless of whether they are connected through the packet-switched (PS) or circuit-switched (CS) network. IMS-based services enable communication in a variety of modes - including voice, text, location, presence, messaging, pictures and video, or any combination of these. In addition

The Global Positioning System (GPS) was funded, developed and controlled by the US Department of Defense. Since the late seventies, GPS has become an important aid to navigation around the world. Initially designed for the US military, GPS became publicly available years later and it is now considered an important feature in lots of consumer products. How does GPS work? Well, basically there are three elements that make everything work: satellites, earth monitoring stations and receivers (ex: cell phone, telefone celular). GPS provides specially coded satellite signals that can be processed in a GPS receiver, enabling the receiver to compute position, velocity and time. Today, most cell phones (telefone celular) are not limited to carry on just a conversation. Features like mp3 player, digital camera and video camera have all become standards in the latest cell phone models. It

A decade ago perhaps the options weren`t very many, but as time went by and with the advancement of high technology, cell phones became increasingly available for just about everyone, and most of us questioned which will be the best suitable service option when choosing a cell phone. Today there are two basic options: the prepaid cell phone service, which allows you to control more closely how much you can or want to spend in a particular month, and the standard cell phone service, which usually charges you a monthly bill. Both services seem to offer very good deals depending upon each person needs. The prepaid service is meant primarily for users who want to keep a closer control of the amount of expenses in phone calls. After the phone credits are gone, one has the option to buy some more or not, keeping his expenses within a limit. This kind of service became very popular and it seems to keep growing every day w

Cell phones (telefone celular) or mobile phones have had a great impact on the way we lead our lives. In today's world, where change is the only constant, cell phones have been upgraded with lots of new technological features. There has been a tremendous growth in the use of cell phones all over the world and now almost anybody has a personal cell phone. What started in 1960s as a bulky radio communication equipment to be used at the time of war, it has now become a small pocket device with a host of special features specially crafted for the common consumer. It satisfies more than the basic need to communicate. It is a fashion statement - an identity of self - and it comes in hundreds of models. Nokia is the world's largest manufacturer of cell phones followed by Motorola, Samsung, BenQ, Siemens, Panasonic, Philips, LG, NEC, Sony Ericsson, Fujitsu and many more. Apart from calling and texting, cell phones are used

Aside from calling, text messaging is the feature getting the greatest use on most cell phones and probably the primary reason for higher than expected bills. With the cost of sending a domestic message around $.15 and receiving one approximately $.10 with the typical cell phone plan, an avid user can rack up an exorbitant bill within days. Customers have struggled to reign in the costs. Individuals and families have instituted "call, don't text" rules within their household, only to find that received text messages still send them over the edge. In some instances, users have been able to block texting from their service but then miss the privacy and the efficiency that texting offers. Many families have tried to quell an adolescent's texting excess by making teens responsible for their own texting costs while others provide only prepaid services to assure that usage is held in check.

Camera capabilities have become common on cell phones and, for some users, these camera phones are their only means of capturing and sharing images. Certainly, the camera within a cell phone is readily available and portable, making them a good option for more spontaneous photography. In addition, they are less conspicuous than all but the more compact stand alone digital cameras, allowing users to take more candid shots easily. Cell phone cameras also have a reputation for their limitations however. From slower shutter speeds that make blurry pictures likely, lack of manual control to adjust exposure, white balance, focus, and so forth, to the common lack of high quality lenses, CMOS sensors, and the megapixels necessary for sharp images, the average camera phone often doesn't compete well with stand alone digital cameras for producing high quality images for print. With recent

Your land line gives you excellent call quality. Your cell phone offers mobility and cost savings on long distance via a cell phone plan with huge pools of anytime minutes, free long distance, and weekend calling. Too bad your best option for economical long distance calling is hindered by a poor cellular signal inside of your home. For many, this is the reality of multiple telephone communication options; each has distinct advantages but none possess all of the qualities that make life simple. Others however, have discovered some options that make integrating their wired and wireless phones a reality. The first option is in the form of a cordless phone that allows the user to make or receive cellular calls. These phones make the connection with your cell phone either through a dock for the cellular phone or the Bluetooth feature. Users are able to bring their cell phone into the home and receive all incoming calls
