# E63-2 Quad-band EGSM 850/900/1800/1900, WCDMA 850/1900
# E63-3 Quad-band EGSM 850/900/1800/1900, WCDMA 850/2100
在这里顺带说一下混乱各地区的WCDMA标准：
UMTS / HSDPA / HSUPA devices operate in the UMTS frequency bands 800/850/1900/2100 or 850/1700/1900/2100 MHz:
2100 (downlink) / 1900 (uplink) for Europe, Africa, Australia, Asia (including South Korea and Japan) and Brazil(usually referred simply as UMTS2100) 1900 for North and South America
2100 (downlink) / 1700 (uplink) for T-Mobile USA alone (usually referred simply as UMTS1700)
900 for Australia (Optus and Vodafone Australia in rural areas) and in countries that currently use GSM900 in the future
850 for North and South America, Australia (NextG)
800 for Japan (NTT DoCoMo in rural areas)
看得我都头晕了……感觉WCDMA的频段比GSM要复杂得多……如果要全世界漫游的话，GSM WCDMA一共至少需要7频，怪不得有同事花大价钱买黑莓9000Bold，常在欧美两地跑，还是黑莓最省心啊……
对了，看到有人问过SAR值问题就顺带提一下，欧版E63型号RM-437的SAR值为1.06W/kg……
这台估计是论坛里的头一台吧，年底了比较忙，满世界的乱跑，时间比较仓促，东西写的也比较乱，有任何异议的请拍无妨不用客气，详细的评测会稍后奉上……
