What is the basic difference between classic bluetooth and bluetooth low energy and if it is low energy then why we are using classic bluetooth why not wi-fi instead of classic bluetooth as wi-fi has wider range?

What is the basic difference between classic bluetooth and bluetooth low energy and if it is low energy then why we are using classic bluetooth why not wi-fi instead of classic bluetooth as wi-fi has wider range? well for your second part of your questions .... i have mentioned a few points on the advantages of bluetooth over wi-fi :: 1) wi-Fi is great for the internet. For wifi to connect to the internet through a stationary access point. This also means Wi-Fi works primarily in fixed locations, sometimes known as "hot spots." Bluetooth technology on the other hand goes with you when you're in the car, you can use Bluetooth technology to talk hands-free on your phone or computer using a headset, speakerphone or car kit. When you're away from home and want to use your laptop, but can't find a hot spot, no problem. You can use Bluetooth enabled 3G and 4G cell phones to tether your laptop and use the 3G and 4G speeds as an internet connection. 2) The speed of your Wi-Fi connection depends on how many other people are connected to the same "access point." If the coffee shop or airport terminal is crowded, your Wi-Fi internet connection may slow down a bit. Because Bluetooth products talk directly with each other, it's very rare that having many products connected at one time will slow down the speed of your connection 3) Bluetooth devices emit a signal that travels for about 30 feet, while Wi-Fi signals travel about ten times as far. ThusWi-Fi devices need more power to generate a stronger signal. And in fact according to a study bluetooth uses less than 3 percent of the power required by Wi-Fi for the same tasks. For example, sending data at the rate of 75 bytes per second over Wi-Fi requires approximately 80 milliwatts of electrical power. Sending data at the same rate over Bluetooth consumes only 2 milliwatts. |

thank you for providing the above mentioned facts but my question is a bit different :
you can have a look at my question in frames like first i asked what is the basic difference between classic bluetooth and BLE ......if it is mainly low energy then why we are using classic bluetooth if we have a low energy solution instead and if we are to look at range or the amount of data transferred then wi-fi has a wider range then why not having two solutions i.e BLE and wi-fi .........what is the practical use-case or you can say advantage of classic bluetooth in present scenario ?

Well i think you are asking why do we need bluetooth classic if we have lower power consumption in BLE.... Thus the limitation BLE have over bluetooth classic is - Bluetooth low energy technology enables new applications and is ideal for applications requiring episodic or periodic transfer of small amounts of data.In a Bluetooth application where streaming data is used. Classic Bluetooth technology is the preferred choice as it achieves substantially greater throughput than Bluetooth low energy technology. |

The Bluetooth low energy does not support continuous streaming of data (audio/video ). It’s mainly used to transfer small amount of data & most of the times the BLE-devices will be in 'Sleep Mode' to achieve low power. So if you need to stream Audio/Video over Bluetooth definitely you need Bluetooth Classic. That means if Bluetooth classic cannot be replaced by Low energy as both technologies have their own advantages & disadvantages. Based on the use-case the technology has to be selected.

Classic Bluetooth technology is the preferred choice as it achieves substantially greater throughput than Bluetooth low energy technology. BLE creates a completely different application area where we cannot utilize Bluetooth Classic or WiFi as both consumes a huge power. The application area of BLE want such devices which can be run using coin cell battery which is not possible using Bluetooth classic or WiFi. |

very well said Akhil kumar but that what's my confusion is ? that if you want to achieve large throughput want to send large data then we have wi-fi which is a better technology than bluetooth classic in all these parameters then why we are using bluetooth classic if we have BLE and wi-fi ................there must be some specific scenario in which we can neither use BLE nor wi-fi and have to use bluetooth classic .......I just wanted to know that which asked in previous post too ?

Here are some more differences:
- The bandwidth required for Bluetooth is only 800 kbps and for WiFi 11Mbps is needed.
- WiFi network is a complex network and hard to configure. On the other hand, in Bluetooth various devices can be connected at a time and switching between devices is easy.
- The power consumption of Bluetooth is very low as compared to WiFi due to Wifi's long range of connectivity.
- The security level of both Bluetooth and WiFi
is also different from each other. Bluetooth has only 2 level of
password to wrap little distance and escape user time. WiFi is a risky
network because when lots of network attached with each other then
hacker may try to access toward connected user and if succeed your data
may be stolen. - Hardware requirement for Wifi implementation is also more than Bluetooth classic. Bluetooth requires only Bluetooth adapter in all the devices connecting with each other whereas Wifi requires wireless adapters on all the devices, wireless router and/or wireless access points.
You are right in saying that WiFi has more + points than Bluetooth classic like higher data rate, high range of connectivity etc but in devices where we don't have much power to allow to be consumed by WiFi and we don't need faster speed and long range, we use Bluetooth Classic, in these type of applications we can't use BLE as BLE doesn't allow voice communication. And as the technology is advancing you can now see WiFi in some devices which previously used only Bluetooth classic but then also they haven't removed Bluetooth classic from that devices. All three technologies BLE, Bluetooth classic and Wifi have different application area, introducing one technology to other's application area will not help.

I have read the differences ......but I am talking on the basis of practical use cases, if any. See my previous posts.
Thank You
