Indoor positioning without GPS / GNSS has its benefits. Its helps to get a position, where no GPS / GNSS signal can be received. It also can be used as a backbone for GPS / GNSS. Nevertheless it can be cheaper.
Indoor Positioning Alliance In-Location
In August 2012 the Indoor Positioning Alliance was founded. It has 22 members (e.g. Nordic Semiconductor, Samsung, Nokia) and names the positing by Bluetooth Low Energy (BT 4.0, BT Smart) and WLAN. Remember that a Bluetooth 4.0 Proximity Tag or Advertising Beacon can transmit a coin cell battery for years. A dream comes real. Indoor Postioning Alliance .
People spend 87% offer the time indoor
The article and the graph by Nokia shows that there is a need for indoor positioning. Humans live indoor and indoor GPS or other satellite based navigation and locating does not work. Even if you get a GPS fix, you have a poor accuracy in 3D. It is impossible to tell the floor by GPS locating only.
Indoor positioning by Bluetooth Low Energy
Bluetooth Low Energy also called Bluetooth 4.0 was renamed to Bluetooth Smart and Bluetooth Smart ready in September 2011. The Motorola Razr Droid is the first Android phone with support of Bluetooth Low Energy / Bluetooth Smart Ready. A device lot a smart phone or tablet with support ot Bluetooth Low energy is called a Bluetooth Smart Ready device. Accesories like a heart beat belt or a proximity tag are called Bluetooth Smart devices.
Where am I? Inside a large building such as an airport terminal Bluetooth low energy tags could be placed in strategic locations to inform cell phone-equipped passengers of their location. More about indoor positing at airport
Bluetooth Low Energy Proximity Tag Reference Design
The application is based on a system on chip. Micro controller, memory, oscillators and the I/O channels are on the same integrated circuit. The certificated Bluetooth Low Energy Stack is running on the chip as well. More about the Bluetooth Low Energy Proximity Tag reference Design.
Indoor locating by Microsoft’s human antenna
Microsoft showed that electromagnetic noise can be used to identify the position of a person in a room, what the person is doing, and even where a hand is placed on a wall. Microsofts vision is to dim the light – my vision is AAL (Ambient Assitet Living) . More about here: concept with Microsoft’s human antenna in AAL
Indoor positioning by WIFI 802.11b
WIFI 802.11b is use to detect change in position of one meter or even less http://ow.ly/UYxZ
Today I can help with WIFI locating on WIFI 802.11n in Cisco WIFI networks. There are ready to use tags, but there are WIFI modules that support this feature too. With such a WIFI module and laptop, PDA, tablet or even a forg lift can be located.
Indoor positioning by Bluetooth 2.1
Research on positioning systems and context-aware applications are being performed in the Alipes project at CDT, Lule University of Technology, Sweden. An evaluation of Bluetooth as a possible technology for positioning was performed during autumn of 2001 in this project. http://ow.ly/14yjE
Indoor positioning by Batman
Batman´s technology in use to see trough walls. Will Gotham City become reality? Is Batman´s technology not science fiction any-more? http://ow.ly/UYhe
Indoor positioning by GSM / GPRS / 3G
http://www.gsm-modem.de/M2M/m2m-faq/how-to-develop-a-tracker-without-gps/ In year 2000 I was the leader of a development team to locate salesmen of tickets at the World Trade Show EXPO 2000 in Hanover, Germany, indoor. We protected the salesmen of the tickets of the gondola train. After a short period they had always thousands of Euro´s in their pocket.
Indoor positioning by active RFID
Open source location tracking project using OpenBeacon tags and OpenBeacon firmware which transmits beacon packets. Such packets can then be received by OpenBeacon base stations in the vicinity. Signals received by one or more base stations can then be used to estimate the position of the tag.
Everybody who is interested in positioning is welcome to subscribe to this Blog by RSS or email (left upper corner). Right now I have capacities for studies and development of prototypes and final products and services left. Behind me are a lot of long term business partners with knowledge and experience in wireless M2M.
Everybody can reach me easy by email to harald.naumann (at) gsm-modem.de or by using the form and ask for a concept, study, development up to mass production. It could be an one stop buying including dedicated support.
