The recent emergence of a "Wi-Fi phones on the market has a lot of people ask," what could be. "In view of Bluetooth vs WiFi phones, we see a possible collision of skills? Not so fast … do not be blinded by the light.
OK, you may have seen some phones with Wi-Fi market recently … and it seems that the penetration of mobile from these "Wi-Fi phones are now only increase with time. It also seems that what is the current userto achieve with Bluetooth … may also be possible via Wi-Fi at some point in the not too distant future.
Below I have listed the primary use cases for Bluetooth and Wi-Fi as "may" provide a solution.
1. Wireless Headset – Wi-Fi headphones take a lot more power Bluetooth, does not seem to be surmountable in time though.
2. The transfer of wireless data – is already possible via Wi-Fi
3. Security – Bluetooth frequency-hopping transmissions to provide security and lessDisorders, but this is not an insurmountable obstacle for Wi-Fi
4. Mobile Phone to PC Sync – possible via Wi-Fi
If a producer pays $ X per chip with Wi-Fi a. .. They could also work to solve these problems and remove from mobile BT.
But in my honest opinion there is more to the story, if you really look under the hood.
So do not believe in competition, the two meet.
Bluetooth will always remain in your laptopfor two reasons. The first is that it allows the headset to low power. Unlike Wi-Fi, Bluetooth allows synchronous transmission of voice, without the need for VoIP. It 'was one of the key conditions for the Bluetooth specification, and means that headsets that conversation can be a good time with the batteries of small size. Spending on VoIP processing for each type, that is not supported native voice, that Wi-Fi is unlikely to ever take away that market. And despite the public Wi-Fi phones, whichonly wireless connections that most never make a headset.
This will reinforce the continuation of Bluetooth in mobile phones is the new variant of low power, also known as Ultra Low Power Bluetooth or Wibree known. This is exciting, the mobile phone provider for their ability to connect the laptop to a new range of accessories such as watches, sports and health sensors connected. This technology is inside the Bluetooth chip itself, so that the functionality of the laptop without addingcharge.
The other important thing about Bluetooth and Wi-Fi function to achieve their different topologies. Wi-Fi in general discussions of access points, Bluetooth devices, while you are talking with other Bluetooth devices in what is known as an ad-hoc connection. 802.11 – the standard behind Wi-Fi is theoretically able to handle ad-hoc connections, but it is a feature that is poorly implemented and lacks interoperability. Much of the power of Bluetooth is to ensure the construction of pile top, which, sinceAbility to find other devices to connect together to bring safe and a series of data transfers. And 'the better part of ten years, Bluetooth has been taken to correct this problem. Wi-Fi has not yet started it all.
Therefore, there is now reconcile their work is in progress, Bluetooth and Wi-Fi, Bluetooth, so that will be used for this initial configuration of the connection, then Wi-Fi is turned on, under the control of Bluetooth, in order to perform higher transfer rate. There are potential problems, this approach, since bothThey use the same frequencies, and if the two are widely used at the same time, can lead to performance problems that are apparent to the user. To combat that is a device to equipment manufacturers and is also working intensively on a combination of UWB and Bluetooth. This provides better noise immunity, higher data rates at close range and a much lower power consumption, which can be achieved for a similar data rate of Wi-Fi.
The reality is that probably will end with three short-rangeWireless standard used in mobile phones in the coming years – Bluetooth (including Ultra Low Power), Wi-Fi and UWB. In the near future it is likely that Bluetooth and Wi-Fi will be merged into a single chip, with UWB as an additional RF chip. Where are all of Bluetooth, which controls the good news is that the user is only dealing with an application interface.
