MXTOTO These are inherent to the WiMAX standard rather than being added on as carrier Ethernet is to Ethernet. As such these devices are best used in areas of good coverage. Providing portable mobile broadband connectivity across cities and countries through various devices. In many cases, this has resulted in competition in markets which typically only had access through an existing incumbent DSL (or similar) operator. Worldwide Interoperability for Microwave Access (WiMAX) is a family of wireless broadband communication standards based on the IEEE 802.16 set of standards, which provide physical layer (PHY) and media access control (MAC) options. It would never have been cost-effective for WiMax network operators to compete against fixed-line broadband networks based on 4G technologies.|Vertical Roller Mill
