The emergence and rapid uptake of always-on mobile broadband is being propelled by new applications, such as live video news, video sharing and social media. And, to meet this demand, more and more operators are choosing to deploy Mobile WiMax.
Rick Rogers, MD of Alvarion: South Africa, explains that Mobile WiMAX is a 4G technology and will initially operate in the 2.3 GHz, 2.5 GHz, 3.3 GHz and 3.4-3.8 GHz frequency bands.
Today, Mobile WiMax can be leveraged to provide the user experience and capacity users are demanding for the full spectrum of mobile broadband services.
“As one of the first 4G technologies to reach the market, more and more countries and operators are adopting WiMax as the mobile broadband Internet technology of choice," says Rogers. "Faced with customer demand for mobile broadband, operators are showing preference for ready-to-deploy WiMax rather than waiting for alternative mobile technologies that may, or may not, be available in time to effectively respond to the market.”
Rogers believes personal broadband is a natural evolution that allows subscribers to literally take their broadband experience with them when they are not connected to the DSL service.
“Cable operators are in a situation where they face steep competition from satellite providers for basic broadcast television and declining broadband Internet service revenues. Today most cable operators offer triple play landline voice, TV and Internet services. The only missing piece is mobility. Mobile WiMax is a natural evolution that completes the offering, also allowing subscribers to take their cable broadband services with them.”
Mobile WiMax networks also offer an attractive, complementary option for cellular operators. This investment in new infrastructure will provide the experience subscribers demand and turn the early introduction of Mobile WiMax into a time-to-market advantage in the personal
In addition, Mobile WiMax addresses many of the network capacity management issues cellular operators face with current 3G services, as Mobile WiMax overlay in densely populated areas can offer immediate expanded capacity, says Rogers.
“The business case for Mobile WiMAX works by enabling affordable mobile broadband services that lead to mass adoption. The cost elements of Mobile WiMax that enable service providers to keep their service offering affordable include: an advanced over-the-air protocol that minimises the number of base stations required, thereby reducing deployment costs; the ability to add applications in response to service demand; and the option to begin with a limited network deployment and increase capacity according to demand.
"Another key factor is the availability of low cost, advanced terminals, which affect not only the total cost of the equipment, but also the user experience and acceptance," Rogers says.
