Wireless IoT is a big dark forest with a lot of trees. This time I have chosen symbolic the LTE-tree. All leaves of the tree you can touch at Embedded World booth 5-139. Additional to the tree for LTE there is one for GPS / Glonass, Wi-Fi, Bluetooth Low Energy, LoRa, ZigBee and a lot […]
Embedded LPWAN & NB-IoT antenna consideration On first quick look the choosing of the right integrated antenna for LPWAN & NB-IoT looks easy. In comparison to the large number of LTE bands the selection is simple because LPWAN (e.g. LoRaWAN, Sigfox, Weightless N) and NB-IoT (EC-GSM and NB-IoT) are on 900 MHz. There is no […]
Year 2015 ended and year 2016 started with a big BANG in IoT and M2M. It was not just the firework display at the sky. In the last few weeks at the end of 2015 several rabbit conjure out of the hat: LTE module CAT 1 LTE module CAT 4 LTE module CAT 9 LTE […]
Embedded LTE antenna consideration Choosing the right integrated LTE antenna is not easy. The large number of LTE bands makes the construction of integrated LTE antennas more complex. All that glitters is not gold. You have to look closely at the data sheet of the LTE antenna. The lowest LTE frequency is 698 MHz. The […]
WyzBee – your IoT enabler The WyzBee board of Redpine Signals includes a wireless module providing Wi-Fi, Bluetooth 4.1, and ZigBee connectivity. Moreover it holds a six-axis inertial sensors, an infra-red receiver, a debug port, push-buttons, LEDs, USB ports, and expansion connector. Last but not least there is a Dual Core MCU with memory, wired […]
Our third patient has a popular name. The manufacturers have called it the magnetic mount antenna. Further details about the third mobile antenna patient are given in the test below. Here are the medical records of the cellular magnetic mount antenna: Frequency bands: GSM 850/900 MHz, GSM 1800 / 1900 MHz, UMTS 2100 Frequency range: […]
Our second patient has a name as well. The manufacturers have called it the cellular stubby antenna. Further details about the second mobile antenna patient are given in the test below. Here are the medical records of the cellular stubby antenna: Frequency bands: GSM 850/900 MHz, GSM 1800 / 1900 MHz, UMTS 2100 Frequency range: […]
Our patient has a name. The manufacturers have called it the Penta-band PCB antenna. More details about the first mobile antenna patient are revealed in the test below. Here are the medical records of the Penta-band PCB antenna: Frequency bands: GSM 850/900 MHz, GSM 1800 / 1900 MHz, UMTS 2100 Frequency range: 824 – 960 […]
Last week a big package of antennas reached me. Step by step I will make the description of the antennas public. The picture shows an antenna for GSM and UMTS flying over ground plane. Such an antenna will radiate directional. This is perfect if you plan a people or pet tracker close to human or […]
GSM PIFA antenna flying over ground A picture can tell more than a thousand words. I do not remember how often I have drawn such a sketch at a customer’s office. It is time to change this waste of time and to start with an antenna proposal gallery online. The GSM PIFA antenna is “flying” […]
