Viva La Wi-Fi. Cox Communications built a Wi-Fi network in the MGM Grand, covering all 5,034 rooms: The cable company also won a bid to unwire the Hard Rock. A Cox exec says that it installed enough access points that only one or two people will share an access point. I wonder if that's based on estimates of how many people may be online at a given time or if Cox actually installed an access point for every two rooms or so. Customers pay $9.95 for a 24-hour period. While Sprint was competitive for the MGM deal, an exec from Sprint made some odd critical comments of the Cox deployment. He says that customers will ultimately want a network that allows them to roam and offers higher speeds. I hope he's not talking about 3G because while that lets users roam it doesnt offer higher speeds…. [Wi-Fi Networking News]
