Not that long ago, any computer with an Internet connection was physically tethered to a desk by a network cable. More recently, WiFi networks have provided a much higher degree of mobility, but nothing that even comes close to widespread coverage. However, WiMax promises greater wireless connectivity reach, with wireless networks that span kilometres rather than a few hundred or so metres typical of WiFi.
Today's workforce, equipped with PDAs, laptops and other mobile devices, demand access to the network from wherever they are, without the hassle of a fixed network.
WiMax allows businesses to deploy a network more quickly, at lower cost, and with greater flexibility than a wired system. “Productivity increases too, since workers can stay connected longer, and are able to collaborate with their co-workers as and where needed,” says Daniel Levy, GM Africa and Middle East at Alvarion.
“This makes WiMax a particularly compelling proposition for SMEs.”
Wireless networks are more fluid than wired networks. A network is no longer a fixed thing. WiMax allows for even more flexibility as it offers specifications for mobile as well as fixed use, so an ISP can provision its customers with hardware to handle both kinds of use instead of relying on separate wired/wireless infrastructure.
“Many SMEs think a wireless network is too expensive for them to install, and many think that they don't need it,” says Levy. “But it makes sense for an SME to go wireless. Not only is set-up relatively simple, it is scalable and allows simple integration with third party applications and services.”
Levy believes SMEs across Africa are realising the value that IP-based connectivity can give to their business as far as exposure and information gathering, communication, responsiveness and cost-efficiency are concerned, compared to any other form of communication.
“As a result, the need for a reliable connection to the rest of the world, with a high level quality of service, has been dramatically increased. Lack of reliability of such a connection will immediately impact the SME's ability to communicate, promote and support their goods and services. Today, the only wireless technology that can assure such quality of service is WiMax. As a pure IP-based technology, it provides all the advantages of a DSL line, without the infrastructure cost associated with wired communications.”
Alvarion's open WiMax approach supports a comprehensive WiMax ecosystem. This includes network equipment, consumer electronics and service offerings, enabling operators to select best-of-breed products from a combination of vendors offering WiMax-enabled solutions. “With WiMax, SMEs can deploy a network of the size they need, and add to it as they grow. It is also an ideal solution for SMEs who need 24/7 access for a mobile and flexible workforce,” Levy concludes.
