Abstract
WiFi using 802.11n or WiMAX (802.16), which one will win? It is not an easy question as it is certainly akin to comparing applies and oranges as WiMax is a wireless MAN technology and Wi-Fi is a WLAN technology. However, the two are certainly in competition as both represent viable solutions for the increasingly market for high speed wireless data.
WiFi 802.11n 和WiMAX (802.16) 谁将在市场竞争中取胜还很不确定，WiMAX是一种无线MAN技术，而Wi-Fi 是WLAN技术。毫无疑问，这两种技术都是正在增长的高速无线数据市场可行的解决方案。
While there is huge industry support for WiMAX, the proliferation of 802.11n-equipped devices is moving forward at a great pace with new laptops and handhelds receiving 802.11n chips. Furthermore, there is a large battle between WiMAX and the so-called cellular 4G standard referred to as LTE.
For more information about the battle between WiMAX vs. LTE, see the Mind Commerce report: Face-off: LTE vs. WiMAX
There are many issues to consider in comparing WiFi with 802.11n vs. WiMAX including data speed, range, environmental and usage factors.
Face-Off: IEEE 802.11n vs. WiMAX provides the reader with an excellent overview of the engineering and operations issues as well as the key factors in considering use of either solution for applications. The publication provides the critical comparative analysis between IEEE 802.11n and WiMAX necessary to make decisions between the two approaches. This report also includes technical analysis examples and real-world system evaluations that examine these two technologies.
