If you are in GPS tracking business and have customers or plans to deliver to Russia, then it makes sense to have a look on a combined GPS/Glonass module.
Bluetooth Low Energy – the digital Swiss knife – part 1
What to do with Bluetooth Low Energy? Which applications can we cover? Several short articles shall give you an idea for useful applications on BLE. The first article is related to my lost key-fob. BLE beacon at key-fob (1) Estimated twenty-five years ago I lost my keys at the ruins of Corinth in Greece. I […]
Pan on Bluetooth Low Energy
Dear Santa, please be so kind and help me with a pan on Bluetooth Low Energy. I know that you are busy these days. Do you have a minute left to grab an intelligent pan with Low Energy for me? Cooking is one of my hobbies. BTW if you have beacons on your wish list […]
Quad-band GSM / GPRS module with embedded Bluetooth module
Quad-band GSM / GPRS / Bluetooth module Just have a look on the world smallest Quad-band GSM / GRPS module on LCC packaging. On top a Bluetooth 3.0 module is already included. Even if there are two radios inside, the price of the combined is close to the half of a standard GSM / GPRS […]
What is an iBeacon?
iBeacon are radio devives on in 2400 MHz range. They use the new Bluetooth 4.0 specification. BT 4.0 is split in classic Bluetooth and Bluetooth Low Energy. Bluetooth Low Energy was previously called Bluetooth Ultra Low Power, and in early 2001, was WiBree. “Wi” for wireless, and “Bree” for Bree in the Lord of the […]

Test report by VNA – cellular antenna VI
The typical faults marked with XXI and XXII in the other graphs are not visible on first view. If you have a closer look you can detect the peak at 1500 MHz range. The bandwidth of this antenna covers all the four GSM bands, UMTS 2100 and even the 2400 MHz band for Wi-Fi, Bluetooth […]
Test report by VNA – cellular antenna IlI
Once more you will detect the typical faults marked with XXI and XXII. The bandwidth for the lower GSM bands is very small and the triangle marker 1 for the middle of the GSM 900 band is on the right side of the gap. There is a need for a matching circuit for sure. For […]
