WiMAX

(Worldwide Interoperability for Microwave Access) An earlier wireless 4G wide area network (WAN) technology that conformed to certain parts of the IEEE 802.16 standard (for more details, see 802.16).

Governed by the WiMAX Forum (www.wimaxforum.org), WiMAX allowed ISPs and carriers to offer last mile connectivity to homes and businesses over the air without the expense of routing wires. In addition, Mobile WiMAX (WiMAX 2) supported users on the go. Whereas Wi-Fi hotspot coverage is measured in feet, WiMAX cells were measured in miles similar to cellular systems. WiMAX competed with 4G LTE service (see LTE, 4G and IMT-Advanced).

Femto Access Points Inside a Building
A "WiMAX femto access point" (WFAP) was a small, indoor base station with a limited range. It connected to the organization's network and passed data to the WiMAX carrier's network via the Internet (see femtocell).

Google, Clearwire and WiMAX
In 2008, Sprint and Clearwire merged to develop Internet access to mobile devices using WiMAX, rather than the traditional CDMA and GSM cellular technologies. Google also invested in the venture. As Sprint transitioned to LTE, in November 2015, WiMAX was shut down. However, a court ordered Sprint to keep WiMAX running an additional 90 days for two large customers covering some 75 cities across the U.S. See Clearwire.

This is suitable for early stages of carnivores and omnivores tropical fish and contains the following: Protein (min.): 55.0%; Ethereal Extract (min.): 10%; Gross Fiber (ymax.): 5.0%; Calcium (max.): 2.0%; Phosphorus (min.): 1.0%; Ash (max.): 10.0%; Vitamin C: 500.0 mg.
The coordinates (UTM, WGS84) of the borders of the maps are Xmin = 396300; Xmax = 472320; Ymin = 4514700; Ymax = 4572500.
In many real data sets, when we want to estimate the unknown characteristic of the population there exists some large ( ymax ) or small values ( ymin ) and to estimate the population quantities without considering these information is very sensitive in either the case the result will be either over estimated or under estimated.
The presence of phenolic -OH and methoxy groups were indicated by IR absorptions at ymax 3376.85 [cm.sup.-1] and 1215.85 [cm.sup.-1] respectively.
The SE represents a set of feature points corresponding to the eyes and the Ymax is the maximum Y value of the set E.
