Something has happened in the world of semiconductors that seemed unimaginable just a few years ago. Researchers at the University of Illinois have developed a technology that allows successive layers of monocrystalline silicon transistors to be stacked directly on top of one another, creating true monolithic 3D circuits. This is the first time this has been achieved at temperatures safe for existing metal connections, paving the way for further increases in transistor packing density without t...

Headends distributing satellite programmes after conversion to DVB-T COFDM digital format are a popular solution used in many hotels. Satellite channels can supplement the terrestrial television offering or serve as the sole source of programming in the installation.

The use of fibre optics in television installations is becoming increasingly popular. This is due to a number of factors, including:

The ULTIPOWER 352SFP N299707 PoE switch has a PD (Powered Device) function which allows it to be powered by connecting to another PoE switch. This function is particularly handy when only one twisted-pair cable is connected to the switch installation site (and the cameras, if installed in the same place, e.g. on a pole)....
