阅读下面的文言文。

   古弼,代人也。少忠谨,好读书,又善骑射。初为猎郎,门下奏事,以敏正著称。太宗嘉之,赐名曰笔,取其直而有用;后改名弼,言其辅佐材也。

  世祖即位,以功拜立节 * * ,赐爵灵寿侯。  上谷民上书,言苑囿过度,民无田业,乞减太半,以赐贫人。弼览见之,入欲陈奏,遇世祖与给事中刘树棋,志不听事。弼侍坐良久,不获申闻。乃起,于世祖前捽树头,掣下床,以手搏其耳,以拳殴其背曰:"朝廷不治,实尔之罪!"世祖失容放棋曰:"不听奏事,实在朕躬,树何罪?置之!"弼具状以闻。帝奇弼公直,皆可其所奏,以与百姓。弼曰:"为臣而逞其志 于君前者,非无罪也。"乃诣公车,免冠跣,自劾请罪。世祖遣使者召之。及至,世祖曰:"卿其冠履。吾闻筑社之役,蹇蹶而筑之,端冕而事之,神与之福。然则卿有何罪?自今以后,苟利社稷,益国便民者,虽复颠沛造次,卿则为之,无所顾也。"

  世祖大阅,将校猎于河西。弼留守,诏以肥马给骑人,弼命给弱者。世祖大怒曰:"尖头奴,敢量朕也!朕还台,先斩此奴。"弼头尖,世祖常名之曰笔头,是以时人呼为笔公。弼属官惶怖惧诛。弼告之曰:"吾以为事君使畋猎不适盘游,其罪小也。不备不虞,使戎寇恣逸,其罪大也。今北狄孔,南虏未灭,狡焉之志,窥伺边境,是吾忧也。故选肥马备军实,为不虞之远虑。苟使国家有利,吾何避死乎!明主可以理干,此自吾罪,非卿等之咎。"世祖闻而叹曰:"有臣如此,国之宝也!"赐衣一袭、马二匹、鹿十头。后车驾畋于山北,大获麋鹿数千头,诏尚书发车牛五百乘以运之。世祖寻谓从者曰:"笔公必不与我,汝辈不如马运之速。"遂还。行百余里而弼表至,曰:"今秋谷悬黄,麻菽布野,猪鹿窃食,鸟雁侵费,风波所耗,朝夕参倍。乞赐缓,使得收载。"世祖谓左右曰:"笔公果如朕所卜,可谓社稷之臣。"

Until recently, mobile radio was to wireless communications what the Yugo was to transportation. With a mixed clientele ranging from truckers using CBs to police armed with walkie-talkies to taxi drivers dispatched by radio, it was viewed as an unglamorous business and a technological backwater.

But specialized mobile radio, as it is known, has been rediscovered. It is now considered one of the biggest prizes in the all-out war for the public airwaves. The reason: high-tech companies have figured out how to profitably rebuild the antiquated dispatching system into an advanced cellular-telephone network that can take on the likes of AT & T and the giant Baby Bells. Upstart Nextel Communications sent shock waves through the industry last week when it agreed to buy Motorola’s SMR frequencies for $1.8 billion.

That could pose a serious threat to cellular hegemony. Although both systems are based on the same basic technology, SMR systems are digital and cover almost 25 times as much area as the average cellular network. SMR handsets won’t work on cellular systems and tend to be bulkier than cellular phones, though they provide more features, like a digital pager service. And while cellular growth has tripled to some 13 million subscribers since 2000, the technology has been losing ground. It is running out of channel capacity so fast, in fact, that 40% of cellular calls in high-density areas like Manhattan and Los Angeles fail to be completed. SMRs have capacity to spare, and service could eventually be priced 10% to 15% less than cellular. Dispatchers predict they will have at least 10 million subscribers by the end of the decade. There are now about 1.5 million users of SMRs.

The addition of another contender to an already crowded field of telephone systems will surely multiply the confusion. By the year 2010, consumers will be able to choose from at least half a dozen vendors of a dizzying array of wireless-communications services, including pagers, voice mail answering machines and cellular phones. Phone and cable television operators, such as Bell South, MCI and Cox Enterprises, are developing so-called personal communications networks, or PCNs, a highly advanced portable-phone system that is expected to cover a wider area, connect to a greater variety of services and be cheaper to operate than conventional cellular.

And many companies that have gambled on the wrong technological standards, and invested billions trying to develop the same markets, will undoubtedly lose a great deal of money before the shakeout is over. "The winners," says Nextel chairman Morgan O’Brien, "will be those who can make the choice for consumers easy." With all the anticipated confusion--mindful of the early years of personal computers--it is likely to be years before anyone calls the purchase of wireless products an "easy" choice.

How did mobile radio systems find its business competitiveness()

A. Its technological features have radically changed

B. It has been rebuilt to cater to various subscribers

C. Its dimensions have been reduced by wide margins

D. It was connected to a greater variety of services
