Standardized RTLS technology

Bluetooth

• Enables tracking of billions of Bluetooth certified devices out of the box.
• Very fast. Data channel is open in 3ms. Enables indoor navigation.
• Low current consumption. Years of battery live time with single coin cell battery.
• Device independent tracking accuracy. Cell based tracking does not rely on absolute values of signal quality parameters.
• Safe. Low exposure to high frequency radiation. SAR only 1% of typical mobile phone or Wi-Fi device.

• Proven technology.
• (Passive) RFID is attractive if number of tracked objects is very high.
• Very expensive network infrastructure.
• Secondary technologies (e.g. Infrared) needed to meet required locating accuracy.

• Secondary technology to improve accuracy of Wi-Fi and RFID solutions.
• Line-of-sight is required.

• Room level accuracy guaranteed.
• Using existing IT-Infra or other secondary technology for data transfer.
• No data transfer option.

• Optimized for large data transfer using high speed.
• Enables use of other applications at the same time.
• Secondary technologies (e.g. Infrared) are generally needed to meet required locating accuracy.
• System cost is hard to predict. Hidden costs.
• Locks down existing IT- infra, which leads to very high maintenance costs.

• Low signal strength. Has no effect on event the most sensitive equipment.
• Designed for mesh- type sensor networks.
• Requires careful planning during deployment, to ensure no interferers are in the vicinity. ZigBee is easy to block with a Wi-Fi access point.
• Marginal technology, used mainly in US.
