题目内容
20．Wireless technology is relatively young．The first generation has been around only since the early 1980s，when analog voice transmission （传送，播送） networks were introduced．The second generation took over in the mid-'90s with the coming of digital wireless voice and data networks，giving us the capabilities that brought about the cell phone revolution we know today．Yet，as remarkable as the technology is，there's still plenty of room for improvement in the roaming capabilities and sound quality of cellular transmission．Enter the so-called third generation---or 3G---which generally refers to networks capable of connecting to the Internet at speeds of 40times the rate of today's cell phones．This level of service promises Internet connections fast enough to download streaming audio and video files，swap digital photos，and hold teleconferences．It also uses the existing spectrum space more efficiently and increases the speeds with which basic data can be transmitted over wireless devices．
The truth is，most business data doesn't need the full-motion video provided by 3G．Generally，the goal is to transmit text data to employees who are attempting to keep in touch with the office while travelling or working from home．"It's simply untrue that current networks aren't good enough to adequately support the needs of your business，"says Erik Lassila，a managing director with Clearstone Venture Partners，a VC firm in Menlo Park，California．"Businesses should focus their technology investments in the area of wireless data transmission，"not streaming video capabilities．
Before giving in to the hype （吹嘘宣传，夸大其词） that surrounds 3G，focus on mobile applications that can help your company gain customer loyalty．Assess how important it is for your business to access accurate inventory data，sales objectives and product details from anywhere via Web-connected cell phones and very small personal computers．Look only at those wireless systems that can enhance your company's business processes and show immediate payback．
It's true that mobile computing will help employees work smarter and more efficiently．But companies must be cautious in how they roll out wireless services and take the time to factor in the ROI before chasing the next big technology．
