Enhanced Tracking Technology May Help RFID加強跟踪技術可幫助的RFID
By 通過 DON CLARK 唐克拉克
A Los Angeles start-up says it has developed a way to dramatically expand the range of a popular wireless tracking technology, opening up many new applications for low-cost identification tags.洛杉磯開辦說，它已經開發的方式顯著擴大範圍流行的無線追踪技術，開放了許多新的申請，低成本的識別標記。
Closely held Mojix Inc. says its enhancements to a technology known as RFID — for radio frequency identification — sharply reduce the cost of setting up wireless networks that can cover entire warehouses, stores, distribution centers and yards where heavy equipment is stored.密切舉行mojix公司說，它的增強技術被稱為RFID的-為無線電頻率識別-大幅降低成本，設立無線網絡可以涵蓋整個倉庫，商店，配送中心和碼的地方，重型裝備儲存。
Such networks can be used to quickly locate goods and track their movements without having to be close to a scanning device.這種網絡可以用來快速地找到貨品，並追踪他們的變動而不必接近掃描裝置。 Networks with similar capabilities today typically require sophisticated RFID tags that cost anywhere from around $4 to more than $1,000 each, said John Fontanella, an analyst at AMR Research.網絡與今天類似的功能通常需要複雜的RFID標籤的成本在任何地方，從周圍的4元以上1000元，每個說，約翰豐塔內，分析師AMR研究。 Mojix says its hardware uses simpler tags that cost as little as 10 cents each. mojix說，它的硬件使用簡單的標記，成本少了10美分，每個。
“I think this could have significant impact,” said Michael Liard, an analyst at ABI research, of Mojix’s technology. “我認為，這可能有重大的影響，說： ”邁克爾liard ，分析師ABI Research的， mojix的技術。
RFID, a more-sophisticated successor to bar codes, is used for applications such as preventing shoplifting of garments in stores and handling payments at bridge toll gates. RFID的，更複雜的繼任者的條形碼，用於應用，如防止買的成衣，在商店和處理費在大橋收費站。 Applying identification tags to pallets and boxes of goods has been touted as a better way to track inventories at retailers, manufacturers and other companies.申請識別標記，以托盤和箱貨物一直被吹捧為更好地跟踪庫存的零售商，製造商和其他公司。 But adoption has been slower than some companies expected, because of conversion costs and other issues.但通過已經開始放慢，比一些公司預期，由於轉換成本及其他問題。
The least-expensive form of the technology uses what the industry calls “passive” RFID tags, which have no power source or means to transmit data on their own.最昂貴的形式，該技術採用什麼產業呼喚“被動式” RFID標籤，沒有權力的來源或手段來傳輸數據對他們自己。 They are activated by radio signals from a device called a reader, which allows the tags to answer by sending information such as product identification numbers.他們是激活的無線電信號裝置，所謂的讀者，這使得標記答复發送信息，如產品識別號碼。
Readers for passive tags typically have a maximum transmission range of about 30 feet, said Ramin Sadr, Mojix’s chief executive.讀者為無源標籤通常具有最高的傳輸範圍約30英尺，說ramin薩德爾， mojix的行政長官。 Partly as a result, companies often only deploy RFID networks in limited locations, such has around loading docks so they can track goods entering and leaving warehouses.部分作為一個結果是，這些公司往往只部署RFID網絡在有限的地點，例如有大約裝載碼頭，使他們能夠跟踪貨物進入和離開倉庫。
But in the late 1980s, Mr. Sadr and other Mojix engineers worked at NASA’s Jet Propulsion Laboratory on technology used in long-range communications to spacecraft.但在20世紀80年代末，先生薩德爾和其他mojix工程師工作在美國宇航局噴氣推進實驗室的技術的使用在長程通訊的航天器。 They attempted to apply some of those concepts to RFID.他們企圖適用的一些人觀念的RFID 。 The system they developed uses a grid of low-cost transmitters to provide radio energy to nearby RFID tags, which respond by sending signals to an unusually sensitive central receiver, Mr. Sadr said.該系統利用他們開發的一個網格的低成本發射機提供能源電台向附近的RFID標籤，作出回應，發出信號，以不同尋常的敏感的中央接收機，先生薩德爾說。
Each of the company’s receivers can manage signals from 512 transmitters — each as far as 600 feet away, Mr. Sadr said.每個公司的接收器可以管理信號從512發射機-每個據六○○英尺遠離先生，薩德爾說。 The resulting coverage area can be up to 250,000 square feet, or about 100 times the coverage area of previous systems based on conventional tag readers, he added.由此產生的覆蓋範圍可達到二五○○○○平方英尺，或約100倍，覆蓋範圍內以往系統的基礎上的常規標記的讀者，他補充說。 Mojix isn’t disclosing exact pricing, but estimates that a network based on its technology will cost 20% to 25% less than other typical RFID systems as well as offer more-sophisticated capabilities. mojix是不公開的確切定價，但估計，網絡的基礎上，其技術將耗資20 ％至25 ％少於其他典型的RFID系統，以及提供更先進的能力。
Mojix isn’t likely to lack for competition. mojix是不太可能缺乏競爭。 Ronny Haraldsvik, vice president of marketing and industry relations at湯家驊哈羅德斯韋克，市場營銷的副總裁和工業關係 Alien Technology Alien技術 Corp., a maker of RFID tags and readers in Morgan Hill, Calif., said Mojix appears to be targeting long-range applications now served by companies that use active RFID tags.公司，製造商的RFID標籤和讀者在摩根山，加州，說mojix似乎是針對長程的申請，現在所服務的公司使用有源RFID標籤。 “They are very entrenched,” he said. “他們是非常根深蒂固的， ”他說。
