Advantages of Bluetooth | Disadvantages of Bluetooth

This page covers advantages and disadvantages of bluetooth technology. It mentions bluetooth advantages and bluetooth disadvantages.

Following are the features of bluetooth technology. This itself is one of the advantages of bluetooth.
• Distance: About 30 to 50 meters
• Data rate: Upto 1 Mbps
• Number of devices in a piconet: 8, unlimited in bluetooth low energy version.
• Spreading: FHSS (Frequency Hopping Spread Spectrum)

Advantages of Bluetooth

Following are the advantages of bluetooth:
➨It creates adhoc connection immediately without any wires. Connection establishment is very quick. User only need to pair the bluetooth PAN connection between two devices.
➨It has low power consumption.
➨It can pass through walls.
➨It has range better than Infrared communication.
➨It has been managed by Bluetooth SIG and hence products from large companies are available and there is no issue of interoperability among different bluetooth vendor products.
➨It is used for voice and data transfer.
➨It uses FHSS and hence data communication is more secure.
➨The technology is adopted in manay products such as head set, in car system, printer, web cam, GPS system, keyboard and mouse.
➨Due to availability of bluetooth headphones, calls can be taken on phone even while driving and doing some other activity simultaneously. This hands free operation relieves great strain.
➨Bluetooth devices are available at very cheap cost.
➨It has less interference compare to other wireless technologies due to use of FHSS technique.

Disadvantages of Bluetooth

Following are the disadvantages of bluetooth:
➨One of the big disadvantages of bluetooth is security. This is due to the fact that it operates on Radio frequency and hence can penetrate through walls. It is advisable not to use it for critical business or personal data transfer.
➨As HomeRF technology operates on same frequency, It has interference from it.
➨The bandwidth is lower compare to WiFi.
➨Battery usage is more compare to the condition when bluetooth is powered OFF. The new technology known as BLE or bluetooth low energy or bluetooth smart is developed to enhance the battery life further.
