Lets take a small deviation from cellular systems this month. Lets see WiMAX and Bluetooth.
Lets talk about the Bluetooth first !! It operated in the unlicensed band, 2400–2480 MHz . Its basically a short distance technology.
The name is really interesting "BLUETOOTH". Isn't it? It's taken from a king who live in Denmark and some parts of Norway in the 10th century. He united some dissonant tribes and created a kingdom!! Bluetooth does the same. It united communication protocols and created a universally accepted protocol.
The specs for bluetooth are
Date rate : upto 1Mbps (Bluetooth2 is upto 2Mbps, Bluetooth3 goes upto
24Mbps)
Transmit Powers : Class 3: 0 dBm (1 mW) 5m
Class 2: 4 dBm (2.5 mW) 10m
Class 1: 20 dBm (100 mW) 100m
These classes are according to distance. As we can see from the distances Bluetooth is really a Wireless Personal Area Network.
Bluetooth technology has grown at a steady pace. Bluetooth originally started with 1Mbps has reached higher data speeds and most importantly has reached lower power consumption values. Lower power has enabled bluetooth to be used in medical and fitness devices as the power falls under the safety limits. In the official release it was mentioned that the Bluetooth4 has "Ultra-low peak, average and idle mode power consumption" and also has an "Ability to run for years on standard coin-cell batteries".
In the December 2011 Issue of Vehicular Technology Magazine, IEEE there was an interesting article about coexistence of WiMAX and Bluetooth and how exactly these two technologies are present in the phone.
Lets talk about WiMAX next time and also the co-existence of these two.
