向YES宽频说不？

作者／吴仲顺专栏 Nov 23, 2010 12:16:40 pm

【无线希望／吴仲顺专栏】本地 著名财团杨忠礼机构在本月19日推介了4G WiMax宽频服务，并将自己定位成行动网路（Mobile Internet）营运商。在还未正式推介前，由于铺天盖地的平面及电子媒体广告，加上大手笔重金投资马币25亿元在建构整个无线网络，这个简称为YES 的宽频服务已经达到吸睛的效果。

杨忠礼通讯执行长李永钜接受台湾《创新发现志》专访时，夸下海口要让YES用户享用全世界第一个全区无死角的WiMax服务。他这番话的用意明显是要说给另外一位竞争业者P1 WiMax听的，因为许多用户深感不满P1 WiMax的数据机必须置放在窗口边才能收到讯号。

身 为宽频服务的用户，相信大家已经对各公司美丽的“谎言”感到厌恶。从“覆盖范围最广、速度最快”、“你割了吗？”（最终反被许多用户“割”掉），直到 YES的“比现有3G网络快上三至五倍”（却不说明到底有多快），许多吃过这些宽频公司暗亏的消费者已经很难被说服。正所谓经一事，长一智，见过鬼的难道 还不怕黑？

李永钜强调，4G发展的成功关键，在于提供大量且丰富的应用程式。为此，杨忠礼通讯砸下了100万美元，作为开发4G应用程式全 球竞赛的奖金。看来杨忠礼通讯的胃口还不小，除了作为WiMax服务供应商，还想藉开发4G应用程式，来推售WiMax无线产品；就像美国只有 AT&T通讯售卖Iphone一样，大赚一笔。但是，杨忠礼通讯的如意算盘是否打得响还言之过早。照我看来，这根本是还没学会走路，就想着要飞 了!

只是覆盖几个大城市

当杨忠礼通讯还无法让消费者享用到优质的行动网路服务时，却在想 着要如何把4G无线产品如手机卖给消费者，试想这将会是一个怎样的结局？YES在于今天的宽频市场其实处于非常尴尬的地位，它将自己定位成带有语音服务的 流动宽频，但是所谓65%的覆盖范围，不过是主要几个大城市（点击查看覆盖范围），实际上根本无法作为手机通讯之用，加上杨忠礼通讯所获颁的Wimax执照并不涵盖东马，通讯用途更成为了天方夜谭。此外，由于技术上的差异，市面上的手机绝大部分无法使用WiMax，因此现有的手机用户要转换到YES来进行通话及上网服务也是不可能的事。

除 了语音通讯的客观限制外，杨忠礼通讯的数据宽频收费率也是一大问题。虽然是划一每3MB 九分钱的收费，然后3GB流量回扣23元，用户需要付67元，但是费用将会随着使用流量的增加而不设限。如果你一个月用10GB就要付210元，不小心下 载了几部高清电影来观赏的话，上千元的账单就等着你来支付！

矛盾的是，李永钜一直强调4G是3G速度的三至五倍，但是使用如此快速的宽频， 流量要如何控制在那区区的3GB呢？难道杨忠礼通讯只是要鼓励大家在它那“高速”宽频上收发电邮、玩玩面子书而已？至于那些耗流量的服务如观看 Youtube和网络游戏就等到大家有钱没地方花时才来做吧！

为何还对WiMax如此热衷 ?

目 前市场上认为未来4G方面有LTE和WiMax两种技术标准，全球最主流的运营商选择以LTE（Long Term Evolution）为主，而新兴的中小运营商则倾向选择WiMAX。在我国，因为两大4G服务供应商如绿驰通讯和杨忠礼通讯都选择了WiMax技术，所 以我们对LTE感到相对陌生。

鲜为人知的是，杨忠礼通讯的执行长李永钜，之前曾经在美国领导Clearwire公司次世代无线联网设备的发 展，主要负责Sprint Nextel的WiMax部门。如今，Sprint已经撤出了在Clearwire的54%全部股权，而Clearwire一直在研发Wimax技术。目 前市场上也在猜测Sprint会不会干脆放弃WiMax，转而采用其他美国运营商正在计划部署的LTE技术。因此WiMax技术的可能死亡就意味着美国的 所有四家无线运营商（Sprint、AT&T、T-Mobile及Verizon）如今都有可能采用LTE一种技术，来建设速度更快、覆盖更好的 4G网络，目前Verizon和AT&T已经这么做了。

既 然美国通讯业者几乎要放弃WiMax了，为何我们还对WiMax如此热衷？目前备受看好的LTE是3G的演进，兼容并支持已有的3G系统，也就是说适合用 在现有大部分的3G手机。LTE理论上的速度也比WiMax快，达到了下行100Mbps，上行50Mbps的峰值速率。

杨忠礼通讯要架设 自己的WiMax网络，并要求用户从通讯设备到手机号码都转换到它的网络，肯定是一项不容乐观的挑战。英特尔就是一个很好的借镜。多年来，英特尔一直在推 进WiMax，试图向各种电脑和外部设备推销WiMax芯片，但是到目前为止，Sprint所销售的WiMax智能手机却只有HTCEvo一款。

撇开往后YES的宽频服务素质不谈，杨忠礼通讯采用了和所有主流3G服务供应商完全不兼容的WiMax标准，逼使消费者只能二选一。如此让消费者感到左右为难的选择，除非你所提供的是物超所值的服务，否则就会变成WiMax的末代皇帝。

Intel Core Duo vs. Core 2 Duo: What's the Difference?

Tue Nov 21, 2006 5:08PM EST

Three people have written to me in the last 10 days asking about Intel Core Duo CPUs vs. Intel Core 2 Duo CPUs. I figured it was time to tackle the topic on the blog.

Intel's really to blame here for a horrific naming convention. Any half-conscious marketing executive would commit suicide before putting both a numeral 2 and the word "duo" in the name of a product, particularly when there's also a product with "solo" in the name. But let's put that aside and look at the specs of each.

Core Duo is Intel's first dual-core CPU. It's a whole new architecture for Microsoft, using two cores on a single die, which, put simply, gives you two chips in one package. Running at lower speeds than the old Pentium line, the Core Duo conserves substantial power vs. ratcheting up clock speed while offering what was, at the time, record-breaking performance.

Now there's Core 2 Duo. In many ways Core 2 is the same as Core: The chips are built using the same production process and fit in the same sockets as Core Duo chips. Putting aside Core 2 Extreme (a fancy version of the Core 2 Duo), you won't see many spec changes: Both chips have the same frontside bus speed of 667MHz, but Core 2 Duo is now available at somewhat faster clock speeds (as I write this, 2.67GHz chips are available). The frontside bus communicates between the CPU and RAM (and other components), and it's a notorious performance bottleneck for computers. The Core 2 also has the same L2 cache that the Core has. However, there are architecture changes to the silicon that give the Core 2 more sophisticated processing abilities. Both chips exist in desktop and laptop versions.

Why does all of this matter? Performance, pure and simple. In my tests, Core 2 Duo computers outperform Core Duo computers on tasks across the board, from rendering graphics and video to spell-checking documents. The speed improvement varies widely, but on average it's about 30 percent. That's significant in an industry that thrives on tiny, incremental improvement. Better yet, there's not an appreciable difference in battery life on notebooks, as power consumption for both chips (at the same clock speed) is about the same.

Now let's consider pricing. Initially, Core 2 chips were more expensive than Core, but that has changed, as Core is practically gone from the desktop market now. Surprisingly, you can now get a 2.13GHz Core 2 CPU for less than the price of a 1.66GHz Core CPU.

Still, expect to see some systems still on the market that use the Core CPU, especially in laptops. Performance is still very good with Core, so don't feel like you're getting second-class goods if you buy a Core Duo notebook, but remember you are buying a chip that Intel is no longer actively selling, and prices for Core 2 systems aren't really any different than they were for Cores. If it was my money, I'd hold out for a Core 2 system unless you got a great deal on a Core... which will be all but vanished from the market in a matter of months.
