deliver high-quality mobile data services. MDM provides support for GSM, CDMA, WiMAX and other mobile devices, this paper focuses on WiMAX.Operators such as Clearwire and UQ require that WiMAX products have a wireless OTA (over-the-air) management function to ensure the reliability of WiMAX networks.Redbend Software announces that Intel, the world leader in chip
wires and the cost is significantly lower than WiMAX, but over time, once the development of WiMAX significantly reduces the cost, DSL technology will be threatened to be eliminated by WiMAX technology.
Ii. WiMAX and Cable
Cable Modem technology can be divided into two-way
In recent years, the mobile communication field presents the trend of data and broadband, WiMAX adopts multicarrier modulation technology, which can provide high-speed data service, and has the characteristics of high frequency spectrum resource utilization, high efficiency bandwidth utilization and large coverage range. The cost of WiMAX is relatively low, it can provide convenience for individuals, famili
The full name of WiMAX is Microwave Access for global intercommunication Worldwide Interoperability for Microwave Access). After combining this technology with Microwave devices that require authorization or authorization-free, the broadband wireless market will be expanded to improve the recognition of enterprises and service providers. WiMAX is the 802.16 standard, or Broadband Wireless Access to Broadban
WiMAX's full name is microwave access to global interoperability (worldwide interoperability for microwave access), combining this technology with the need for authorized or unauthorized microwave equipment, the lower cost, will expand the broadband wireless market, Improve the awareness of business and service providers. WiMAX is the IEEE802.16 standard, or wide band wireless access (broadband Wireless ACCESS,BWA standard). It is a wireless metropoli

WiMAX revolution
WiMAX and voice communication are different from each other. It was initially designed as a wireless IP system. WiMAX not only reduces costs from the perspective of chipset, but also provides services from the perspective of operators' capital expenditure and operating expenditure. Along this path, WiMAX
With the development of multimedia communication, people need a higher rate, higher coverage rate, and a mobile wireless broadband access method. The emergence of WiMAX technology meets people's needs for wireless Internet.
If Wireless LAN technology solves the "Last one hundred meters" access problem, WiMAX technology is the best solution for "last mile" access.

WiMAX Overview
World wide (WiMax) is a wireless transmission technology based on the IEEE 802.16 standard. As the "last mile" technology connecting users, WiMax is developed to replace broadband wired networks such as DSL and support mobile broadband wireless access, it uses OFDM transmission technology for NLOS connections, providing a data rate of up to 75 Mbit

Recently, WiMAX supporters have experienced ups and downs. Poor aspects include the announcement last year that the US operator Sprint Nextel and Clearwire had terminated cooperation, and their intention to work together to build a mobile WiMAX network covering the entire United States was also abandoned halfway, this has aroused serious questions about the potential of this wireless te
