Imec demonstrates low power beamforming transceiver chipset

Imec, in collaboration with Panasonic Corporation, has presented a 60GHz radio transceiver chipset with low power consumption, that delivers high data rates over short distances at the IEEE International Solid-State Circuits Conference (ISSCC2013). Imec was able to drastically boost the link budget of the system by introducing beamforming into the radio architecture. This multi-Gbit 60GHz chipset could pave the way toward small size, low-power, low-cost, high-data rate solutions for battery-operated consumer devices, such as smart phones and tablets.

4G mobile spectrum auction disappoints raising ‘just’ £2.34bn

Ofcom, the telecoms regulator, has announced that the auction of 4G mobile spectrum has raised £2.34bn, well below the £3.5bn pencilled in by the Treasury and the Office of Budget Responsibility who had expected it to raise upwards of £3.5bn. The auction netted far less than the £22bn that was raised thirteen years ago when 3G licenses were auctioned.

CommScope works to address challenges of cell densification in wireless networks

To alleviate capacity concerns in their macro networks, many wireless operators are exploring or deploying lower power and smaller footprint cell sites. Often referred to as small cells, these applications, which are designed to increase overall sector density, or capacity, can present challenges when it comes to acquiring sites and integrating them into the macro wireless network.
