Smart Floor
 
In Georgia Tech’s Smart Floor Proximity Location system , embedded pressure sensors13 capture footfalls, and the system uses the data for position tracking and pedestrian recognition. This unobtrusive direct physical contact system does not require people to carry a device or wear a tag. However, the system has the disadvantages of poor scalability and high incremental cost because the floor of each building in which Smart Floor is deployed must be physically altered to install the pressure sensor grids.

Georgia Tech的Smart Floor Proximity Location system 嵌入pressure sensors13 並利用data中的position tracking 和 pedestrian recognition來獲得footfalls。這個systme (unobtrusive direct physical contact system) 並不需要人們帶著device 或Tag。而這個System的缺點是低延展性及高成本。因為建物的地板都要部署且必須要改變sensor以適應當地環境。

在格魯吉亞高科技的智能樓靠近定位系統，嵌入式壓力sensors13捕捉腳步，而該系統所使用的數據為位置跟踪和行人的認可。這不防礙直接的身體接觸系統並不要求人們隨身攜帶的設備或穿標籤。不過，由於這個系統的缺點窮人的可擴展性和高增量成本，因為一樓的每一個建設，其中智能地板部署必須身體變造安裝壓力傳感器網格。

E911

The US Federal Communications Commission’s E911 telecommunication initiatives require that wireless phone providers develop a way to locate any phone that makes a 911 emergency call (http://www.fcc.gov/e911). E911 is not a specific location sensing system, but we include it because the initiatives have spawned many companies that are developing a variety of location systems to determine a cellular phone’s location. Location systems developed to comply with the E911 initiatives will also support new consumer services. For example, a wireless telephone can use this technology to find the nearest gas station, post office, movie theater, bus, or automated teller machine. Data from many cellular users can be aggregated to identify areas of traffic congestion. Many business speculators tout this model of mobile consumerism, or m-commerce, as being the “next big thing.” To comply with E911, vendors are exploring several RF techniques, including antenna proximity, angulation using phased antenna arrays, lateration via signal attenuation and time of flight, as well as GPSenabled handsets that transmit their computed location to the cellular system (http://www.airbiquity.com). To meet the FCC requirement, positioning must be accurate to within 150 meters for 95 percent of calls with receiver-based handset solutions such as GPS, or to within 300 meters with network-transmitter-based approaches.

The US Federal Communications Commission的E911 telecommunication主動要求手機供應商開發emergency call(911)to locate any phone.E911不是個具體的location sensing system，但還是include it，因為這個提議已經促成多家公司進行開發多種的手機定位系統，而該系統也支援新的服務性消費。For example，手機可以用這個技術來尋找離自己最近的gas station, post office, movie theater, bus, or automated teller machine等等。
那些資訊來自各用戶的使用資訊彙整，可以用來確定該地區交通壅塞情況。很多business speculators 覺得這種mobile consumerism(或者稱為m-commerce)是未來的目標。為了E911，廠商開始exploring其他的技術，像是antenna proximity、angulation using phased antenna arrays、lateration via signal attenuation and time of flight以及GPSenabled handsets 來傳送自己所在的位置給cellular system。為了滿足FCC的需求，精準的在150米內95%的手機來電與接收的定位，就像是GPS300公呎內network-transmitter-based一樣。

美國聯邦通信委員會的911電信主動要求手機供應商開發的方式找到任何電話，使911緊急求助電話（ http://www.fcc.gov/e911 ） 。 911不是一個具體位置傳感系統，但我們包括是否因為舉措已促成許多公司正在開發一個品種的定位系統來確定手機的位置。定位系統開發，以符合911倡議，也將支持新的服務性消費。例如，移動電話可以使用這種技術來尋找最近的加油站，郵局，電影院，公共汽車，或自動櫃員機。數據由許多細胞用戶可以加以匯總，以確定地區的交通擠塞情況。許多商業投機者兜攬這種型號手機的消費主義，或M -商業，被稱為是"下一件大事" 。遵守的911 ，廠商也都在探索幾種射頻技術，包括天線接近，而角使用相控陣天線， lateration經信號衰減和飛行時間，以及gpsenabled的手機傳送自己的電腦位置，以蜂窩系統（ http://www.airbiquity.com ） 。以滿足FCC的要求，定位必須準確，以150米的95 ％的來電與接收機基於手機的解決方案，如全球定位系統，或以不超過300米網絡發射機-基礎的辦法。
