Breaking New Ground with Wi-Fi Radio
In addition, the Bold breaks some new ground with its Wi-Fi radio, adding support for the commonly neglected 5GHz band and 802.11a to the 802.11b/g and enterprise-grade Wi-Fi security RIM first introduced last year with the BlackBerry 8820. RIM typically does an excellent job on its WLAN radio implementations-making sure the radio is designed to maximize the security, battery life and roaming performance demands of enterprise-grade customers-and the Bold lives up to heritage. But it's this excellence with Wi-Fi that makes RIM's ongoing lack of commitment to the technology all the more bedeviling. The lion's share of the company's device portfolio still does not include Wi-Fi, including its brand-new flagship device, the touch-screen BlackBerry Storm.The Bold comes with a 1,500-MAhr battery that is rated for 4.5 hours of talk time or 13.5 days on standby. My battery tests showed the Bold slightly bettered these claims, delivering 5 hours and 8 minutes of talk time. The Bold is not excessively large, nor is it particularly petite. Measuring in at 4.48 by 2.6 by 0.59 inches and 4.8 ounces, the Bold is slightly wider and thicker than the iPhone (which is 2.4 inches wide and 0.48 inches thick) and significantly thicker than the Nokia E71 (0.39 inches thick). With a base price of $550, the Bold can be purchased for $300 after rebates and with a two-year service agreement; it is available for the AT&T network.
The Bold is also RIM's first 3G device for GSM networks, as the smartphone supports the 850/1,900/2,100MHz bands for UMTS/HSDPA in the United States and abroad.
