WiMAX
While LTE is the Choice for Many Mobile Carriers, a World of Opportunity Remains for WiMAX Operators and Vendors
At this time there is little controversy over the fact LTE (Long Term Evolution) will become the dominant global 4G wireless technology over the next ten years. The only real issue at this point is when most carriers will opt to migrate to LTE and how long HSPA+ and CDMA EVDO Rev A will delay LTE deployments.
But the wireless world does not just include mobile wireless, particularly high-end, 3.5G and 4G, mobile wireless. India and China, the Middle East and Africa, the South American continent and parts of the Asia-Pacific region are examples of this; lower-tier technology markets due to spending constraints of the subscriber audience.
Many areas within these regions are also severely lacking in broadband infrastructure due to the same lack of spending power among the potential subscriber audience. This is changing however due to government efforts, falling prices on broadband access and cheaper access devices, such as the ultra-low-cost PC.
Reaching Sustained Growth in the WiMAX Market
Strong subscriber growth over the past year has demonstrated the appeal of WiMAX technology. Now operators are aggressively expanding their networks to keep up with the growth in demand.
The WiMAX market has entered a stage of sustained growth. Operators have moved from the slide deck and vendor selection stage to the more demanding jobs of building networks and signing up customers. A couple of years ago, the focus of operators’ attention was on the fundamentals - which type of equipment worked best and how fast the price of subscriber units would decrease. Today operators are asking vendors for a wider variety of devices that will enable them to increase the capacity and reach of their networks, and new base station form factors that will give them the flexibility they need as they expand their networks. They are also experimenting with new services and new ways to reach their subscribers, and to make the services more attractive.
Five Essential Elements of WiMAX Security
Security was a key failing of older broadband wireless systems of the past. The why of it is easy to comprehend---any network that transmits its data across wireless signals rather than wires is inherently more open to interference, intrusion or assault. This doesn't mean solid broadband wireless security is impossible, just much more difficult.
Happily, as broadband wireless networks have matured security features have improved. Even the tried-and-true Wi-Fi and proprietary networks widely deployed have improved their security protocols.
With the advent of WiMAX, the security toolsets available to broadband wireless service providers have reached all time highs of functionality. Today's WiMAX networks can be secured more effectively than ever before. However, as important as securing the WiMAX network is, there are additional considerations that carriers should evaluate as part of a thorough security implementation. In fact there are five primary aspects of WiMAX security that should be considered when designing a security plan for your WiMAX network. These range from mitigation techniques at the physical layer to improved wireless authentication and encryption to intrusion protection and data transport security.
