Answer:
To answer this question it is important to understand the state of technical fragmentation experienced in the past by the mobile wireless and fixed broadband wireless industry. Early broadband wireless systems began as extensions of indoor local area network (LAN) technology known as Wi-Fi Technology or the 802.11b protocol. This standard has evolved into a ubiquitous and widely available standard used in short range hotspots all over the globe. However, the media access controller (MAC) and physical layer (PHY) specifications for this protocol are suboptimum for outdoor citywide wireless networks or metropolitan area networks (MAN). Recent updates and new standards such as 802.11g, 802.11a and 802.11n have improved these elements. However, once again these technologies are configured for best performance in small venues and at short range.
