iphone裡面設置-隱私-定位服務-系統服務裡面的蜂窩移動網路搜索和無線區域網聯網和診斷與用量都是什麼

引自：Hidden iPhone Privacy Settings: A Guide

Cell Network Search: This tracks cell tower usage and congestion, and sends the data back to Apple for analysis as to what towers are being used the most, how you move between cell towers, and which ones are overused. It does not help your phone locate a cell tower. Turning this off will not affect your phone』s performance, according to Apple.

蜂窩移動網路搜索：把手機跟基站通信得到的一些信息傳給Apple，可關之！

Compass Calibration: This gives the Compass App the data it needs to function – pretty simple. If you turn this off, your compass stops working.

指南針校準：開了才能用指南針！

Location-Based iAds: Your iPhone will send your location to Apple in order to provide you with geographically relevant ads. Turning this off will mean that you won』t get ads relevant to where you are, or the totally sweet offers that come with it.

基於位置的iAd廣告：提供基於位置的廣告，可關之！

Popular Near Me: Locational data about the Apps you use and have purchased will be sent to Apple in order to promote Apps to others in your area. Basically, it』s geotagging Apps for advertisement – turning it off will not affect your phone』s performance.

附近的熱門應用程序：把你的位置和你的安裝的應用信息傳給Apple，可關之！

Setting Time Zone: Your time zone will be instantly adjusted according to your geographic location. Ever notice how as soon as you turn on your phone after a long flight, it displays the local time perfectly, even before getting cell signal? It』s this setting. If you turn it off, you』ll lose that functionality.

設置時區：通過GPS定位自動設置時區。

Traffic: Monitors your geographic movement and interaction with cell towers in order to understand traffic patterns for the Maps program. This seems to only be used for Apple』s Maps program. However, turning it off will not affect your phone』s performance.

路線與交通：監控你的位置和與基站的通信，供Apple自帶的地圖使用，可關之！

Wi-Fi Networking: This particular setting is interesting, and requires some explanation. As you move around a city, your iPhone is constantly picking up WiFi signals. It geotags that data (「XYZ WiFi is at this GPS location」), encrypts it so that it is anonymous and unique (otherwise the data would look like all hotspots are named 「linksys」), and stores it as what Apple calls 「crowdsourced Wi-Fi Hotspot locations」. Next time someone walks by that exact hotspot, their iPhone will know where they are without using GPS – because you basically already 「marked」 the area. Shutting this setting off will stop that info from being sent to Apple. It will not affect your phone』s performance.

Wi-Fi 網路：把你的位置和掃描到的Wi-Fi網路信息傳給Apple，可關之！

Frequent Locations: Stores the frequency with which you visit certain locations, and the time spent in each place. If you go into this menu, you』ll either think it』s really cool, or really creepy: it has a list of your most frequently visited places, and how many times you』ve been there. Turning this off will affect your phone』s features! The iPhone uses this to figure out where you live and work. When you visit your 「Today」 tab, and it says 「With current traffic, it will take you 20 minutes to get to work」 – it』s doing this using your frequent locations. Turning this feature off will also disable these functionalities.

常去地點：記錄常去地點，可關之！

雖然還不全，但是感謝
