Here are the pros and cons of Bluetooth technology:

Pros

Bluetooth has plenty to offer in an increasingly competitive market. Bluetooth offers a solution by promising the freedom from the wires and seamless networking that has yet to be equaled by LAN (Local Area Network).

In the primary niche markets of wireless and handheld devices, the closest Bluetooth competitor is infrared technology(IR). Infrared offers several key features, although the line-of-sight it requires doesn’t go through walls or around obstacles.

Unlike infrared technology, Bluetooth isn’t limited by line-of-sight and it does operate in ranges of up to 100 meters. Additionally, Bluetooth offers low power as well as low processing requirements. Essentially this indicates that it’s ideal for integration within small, battery-powered devices. In other words, the typical applications which incorporate Bluetooth are virtually limitless.

Cons
Bluetooth has a number of important features and one would be hard pressed to find cons. The only noticeable downsides are the data rate as well as potential security issues. As a comparison, infrared can have reach data rates of up to four MBps compared to Bluetooth which offers one MBps.

For this exact reason, infrared cannot be disqualified and is considered by most to be a complimentary technology to Bluetooth. Infrared also offers an inherent security benefit since it operates within a line-of-sight.

The enhanced range and radio frequency (RF) of Bluetooth place it somewhat vulnerable to being intercepted and attacked. As a result, security specifications are a key aspect to Bluetooth technology.

Due to its many advantages, Bluetooth is the optimal short-range wireless technology. For people who have tried it, love it, and they strongly believe that Bluetooth will remain the leading force in the wireless market.
