Why Bluetooth needs Adderall
How bouncing around like crazy makes your audio cleaner
. All remaining radio frequencies are locally auctioned off (e.g your local jazz radio station may have rented the 103.2 radio station, look at the US's radio allocation here (absolutely mental!)). The IEEE (and governments) are careful when assigning new frequencies to ensure GPS signals aren't drowning out your TV remote's signals or that your local pop music station isn't overlapping your home WiFi signal. What's interesting is that despite such planning, nothing's perfect and the Bluetooth and WiFi standards were assigned the same block of radio frequencies. Curtly, WiFi has 11 channels you can choose to broadcast from. Small interferences and quality of antennas etc. means that your channel will be wider than a channel and bleed into other channels. It's an unwritten rule that you choose either channel 1, 6 or 11 to avoid interference. Some WiFi emitters are silly and emit between these channels and mess everyone up.
WiFi standard. International standards are fun, if you're so inclined, lookup random ISO standards. Here's a detailed 6 page report on the standard way to brew a cup of tea. Accompanying Video.
. Bluetooth hops 16x faster than the human eye. The thinking is, going back to our walkie talkie example, if you stick to one channel and hope for the best, it might start out fine, but once the channel gets cloudy, you have to change over, a process which can take a few seconds to communicate. By the time your Bluetooth phone call has dropped out 3 seconds, you've already lost the battle. This is where the fast hopping brilliance comes in. If half of the 79 frequencies in a second have interference and those data packets get lost, you have 800/1600 packets of data, which is more than enough to trick the ear into thinking audio was continuous the whole time. This does become an issue once this number drops to 20 "clear" frequencies or 400/1600 successful attempts. Decades old Bluetooth versions did this, but the standard was improved. Now, both Bluetooth devices still fundamentally do the same agreed random pattern, but once a noisy frequency is found, they both agree to move on to the next random frequency when the noisy one comes up (it then attempts on the noisy frequencies often to see if it clears up). This makes data transmission extremely successful, but it doesn't need to be.
There are 4000 opinions on this, draw your own conclusion to the actual answer, may I continue with my illustration?
just so you can have a continuous audio stream.
Perhaps not 100,000 but 1600 * 60 = 96,000. However that's not as nice a number so it can get shoved in this footnote than join the main content hahaha.
