The battery drain of having wifi turned on is minimal. The Wi-Fi networks that you are nearby learn nothing about your phone just by your turning on Wi-Fi. You would have to actually connect to the networks for them to discover your phone, and that is not necessary for the improved location experience.
Your phone will never connect to a new network without your specific action. Life gets only one piece of information from wifi location: better location. The number of cellular towers and signal strength measurements makes it easier to determine location than satellite. But, when cellular signal is sparse or partially blocked like in buildings or around other radio signals, gaining a location fix is not only unreliable but can also consume battery power.
In contrast, Wi-Fi positioning systems require the least electrical requirement to function. Wi-Fi technology was specifically designed for nearby network communication. Smartphone operating systems need only collect the identifiers and signal strengths within range. A single internet request with this data set will return an approximate location with minimal battery drain.
Another advantage of Wi-Fi positioning is its passive nature. Although Wi-Fi positioning requires Wi-Fi access points to function, it does not require connection to these access points or Wi-Fi hotspots.
Instead, Wi-Fi positioning works by listening for the broadcasting networks. Your smartphone analyzes the identities and strength of each Wi-Fi signal in the vicinity. Then, the process will use that information to triangulate an approximate location for your device. This process is relatively effective, capable of providing a meter range of location accuracy using Wi-Fi access points and infrastructure with no calibration.
GPS and cellular signals tend to bounce off structures, particularly in a condensed set of structures like cities. This can lead to a reasonably inaccurate location. In contrast, Wi-Fi positioning can effectively produce location approximations within 5 meters in indoor settings with some calibration and fine-tuning. Most buildings already have Wi-Fi access points installed, so it is far easier and more cost-effective to use these existing hardware.
Additionally, Wi-Fi infrastructure is continuously growing, and with more access points will come more accurate location approximations. The good news is that this interference is very rare, but it is advisable that you avoid turning on GPS and Bluetooth at the same time. A person can block the transmission of Bluetooth signals intentionally or unintentionally. If you want to block Bluetooth signals deliberately, then you can use a device like a jammer.
Jammers emit similar signals thus interfering with the normal functioning of nearby Bluetooth-enable devices. The jammer will prevent other Bluetooth-enabled phones and gadgets from accessing your devices. This will make it a great option if you want to maintain your privacy.
Bluetooth signals can also be blocked unintentionally by obstacles like buildings, concrete walls, and pillars. If you reside in an area with many buildings, trees, and other similar obstacles, then pairing your Bluetooth devices can prove to be a huge challenge.
Many of these obstacles consist of dense materials that tend to deplete the signal strength between connected devices. Identifying and eliminating all obstacles that help maintain signal strength between your Bluetooth devices. Nevertheless, some devices are capable of maintaining signal strength even with existing obstacles. These devices are Low Energy models and they can stay connected up to 90m, regardless of whether or not obstacles exist.
Bluetooth technology is not a necessity for location services. It is only recently that different business entities have started using Bluetooth for location services. Storeowners require Bluetooth in order to discern the exact position of potential customers inside their stores. Big companies like Apple and Google have invested in beacons that can tell your location via Bluetooth so long as you are within range.
The owner of the store where the iBeacon is installed has to register its exact location in a central database. Google and Apple will then gather your data and tell storeowners about you.
The information obtained is the usual demographics such as gender and age. Other information such as the kind of apps you have, your frequently visited stores, and your subscriptions will also become available if you turn your Bluetooth on. Location accuracy is important for business owners, marketers, and consumers alike.
With just 4 of these satellites your iPhone can determine its location within 10 meters. With AGPS, instead of waiting for the live downloads of position data from satellites, any future satellite locations can be estimated. These estimates are downloaded via a network connection in seconds. However, relying on cell towers outside of urban areas are more problematic as tower tend to be farther apart. This is where Wi-Fi "fills" in.
