This 100 MHz frequency counter is a great example. [Michael] just finished building it using a Papilio board. Of course we’re not talking about discreet chips here. The Papilio is an FPGA ...

[mircemk] had previously built a frequency counter using an Arduino, with a useful range up to 6 MHz. Now, they’ve implemented a new design on a far more powerful STM32 chip that boosts the ...

The 698-806 MHz range of TV channel frequencies (UHF 52 through 69) that were made available when the U.S. switched from analog to digital TV in June 2009 (see digital TV transition). The FCC ...

CDMA 850 is CDMA technology operating in the Cellular (850 MHz) frequency band. Before the existence of GSM 850, the Cellular band was often referred to as the "800 MHz" band. "850 MHz" implies a ...

India's telecom regulator, TRAI, recommended allocating the remaining 5 MHz of 700 MHz spectrum to Indian Railways for safety applications. This adds to the 5 MHz already allocated in 2021. TRAI ...

The "700 MHz band" is actually two bands: Upper 700 MHz and Lower 700 MHz. Each has its own set of blocks. That means you need to be careful when talking about the 700 MHz "C Block", for example ...

In addition, 900 MHz operates on a lower frequency range that allows it to penetrate through buildings easier and be more resistant to interference. “It’s always important to look at existing ...

Top digital TV broadcasters warn NBTC’s latest move could cause widespread blackouts and collapse Thailand’s digital ...

Since 1995, the FCC has allowed RAIN RFID operation (as well as other Part 15 devices such as baby monitors and cordless phones and tolling systems) in the designated 902-928 MHz frequency band. Other ...
