Bluetooth 5 was released in 2016. The new features that are focusing on IoT support were included. It had a two times higher transmission speed in BLE technology, going up to two megabits per second, and also two times more improved advertising message size extension was also included, four times increasement in advertising range such that it could reach about 240 meters. That's a significant distance. It brings about eight times more advertising capacity. New coding scheme to support error correction and higher output class was added up to 100 milliwatts. So, we talked a lot about these different standards. Let's organize what we learn into a table format so that we know the differences, comparing them side-by-side. Here we go. The specs that we will look into are when it was adopted, because release time is very important; then there was maximum transmission rate, and looking at things like the BR mode, as well as the BLE, LE, low energy mode; standard wireless PAN range of distance, of service, and then improving paring without a PIN; improved security, always important; and NFC support, near-field communication, very important. The standards look like this. In 1.1, which was released in 2002, the overall maximum transmission data rate was at the 723.1 kilobits per second, with a range of 10 meters like a standard wireless PAN range. The range stays the same. The transmission overall data rate stays the same. The improved security feature was definitely added, and that helped. Then we go to 2.0 plus EDR technology. Over here, you can see the EDR definitely kicks up the data rate to exceed beyond 2.0 megabits per second. It reaches up to 2.1. The range is the same. Improve security. Another key feature of 2.0 plus EDR is NFC support. We go to 2.1 plus EDR. The data rate goes even higher to three megabits per second. The range stays the same, but it has the feature of improved pairing. 3.0 plus HS. This here, you can go up to 25 megabits per second if you have the plus HS standards that are supported of your device. So, in other words, if you're just using 3.0 without plus HS, then this data rate will not be achievable. Please keep that in mind. The other features are the same as it had in the 2.1 plus EDR mode. Then going to the 4.0, here we have the data rate at 25 megabits per second, and also there's a one megabits per second data rate. The overall wireless PAN range increases up to 50 meters. This is a significant improvement. Having the range up to 50 meters, that's compared to the 10, 10, 10, 10, 10 you see over there, this is a range five times of increasement. This is significantly important. The other features are the same as before. Then we go to 5.0. Here you can see that the data rate of this point, which was one megabits per second, can go up to two and the other features stay the same. Looking at other specifications, comparing it in terms of what you see over there, voice dialing, call mute, and other characteristics, will go down this way, where we can see voice dialing was included in all and call mute was included in all. So far, so good. But then, this is where the new technologies, 3.0 plus HS and beyond, differentiate themselves from the former ones, and that 802.11 cooperated transmission. That is indeed the plus HS, that feature there, co-located devices. Then we have low power consumption. It started with the 3.0 plus HS, but it becomes really mature when we go to low energy, BLE technology that is included in 4.0 and higher modes. In addition, when we go to 5.0, you will see that error correction in the physical layer coding, as well as high output power transmission is a characteristic, a feature of Bluetooth 5.0 alone. These are the references that I used, and I recommend them to you. Thank you.
