WiMAX is the most flexible, reliable, secure, carrier-grade wireless technology on the market today. The figure below illustrates the differences between WiMAX and Wi-Fi.
WiMAX FAQs
Q: How secure is WiMAX?
A: While no network is entirely “hack proof”, WiMAX has a number of strong security measures including a) DES and AES traffic encryption, b) EAP and X.509 certificate authentication and c) proprietary handshake procedures that make hacking into a WiMAX network very difficult.
Q: What interference mitigation tools does WiMAX use?
A: WiMAX is based on Orthogonal Frequency Division Multiplexing (OFDM) which eliminates many forms of interference. Another tool, Dynamic Frequency Selection enables a WiMAX devices to detect interference and then move to an open frequency to avoid harmful interference.
Q: How reliable is WiMAX?
A: A WiMAX network can be engineered to offer 99.999% availability. Tools such as Dynamic Bandwidth Allocation detect interruptions to a service flow and dynamically boost the bandwidth on that link ensuring smooth service. Many vendors build redundancy into their subscriber devices to ensure a highly reliable service. Finally, WiMAX components are built to offer 40 years mean time between failure (MTBF).
Q: Can WiMAX carry telephone or video traffic?
A: WiMAX was designed to carry voice and video. WiMAX offers a number of quality of service (QoS) mechanisms including: a) prioritization of voice and video traffic over data traffic b) low over-the-air latency of around 10 milliseconds.
