AT&T continues to build its cellular network on an evolutionary path to 5G by expanding the cities served by what the carrier calls "5G Evolution" technology.5G Evolution, which encompasses 4x4 MIMO, 256-QAM modulation and carrier aggregation, is not really 5G, rather capabilities defined by the 3GPP in the LTE-Advanced and LTE-Advanced Pro specifications. AT&T is also adding LTE-LAA — which uses carrier aggregation in the 5 GHz Wi-Fi spectrum to increase data rates — to the mix.

South Korean mobile carriers are feeling the pinch as they are facing rising costs due to the establishment of the fifth-generation mobile network infrastructure while being pressured to cut mobile service fees, industry insiders said Sunday. Amid the increasing pressures on the country’s three telecom companies to cut households’ mobile costs, the upcoming auction for 5G frequencies in mid-June is predicted to charge the operators huge costs, making it harder for them to seek margins.

According to Mark Granger, vice president of GlobalFoundries’ product line management, the IATF 16949 standard is a binding prerequisite for being allowed to manufacture semiconductor products for the automotive industry as a supplier. IATF 16949 is based on the existing ISO 16949 standard for quality assurance and supply chain protection but modified by the International Automotive Task Force (IATF, comprising of BMW, Chrysler, Daimler, Fiat, Ford, GM, Renault and VW)) according to the needs of the automotive industry. In order to achieve such certification, semiconductor manufacturers must prove that they fully meet the strict safety and quality standards. Above all, this includes guaranteeing a failure rate of 1ppm, i.e. a maximum deviation per million parts produced. In addition to the certification requirements for the production site and manufacturing processes, GloFo’s 22FDX technology has also been qualified to meet these technological requirements.

The U.S. Federal Communications Commission gave the domestic 5G industry a boost yesterday by announcing its pre-auction process to hold two millimeter wave spectrum auctions for 5G use, starting on November 14th. Portions of the 28 GHz and 24 GHz bands are proposed to be auctioned in two batches, with the second auction beginning after the first is exhausted. FCC proposed to auction 5,986 licenses in the millimeter wave bands, known as Upper Microwave Flexible Use Service (UMFUS). The 27.5–28.35 GHz (28 GHz) band falls under Auction 101 and 24.25–24.45 and 24.75–25.25 GHz (24 GHz) under Auction 102.

At just 3.3mm high, the antennas are ultra-compact, so they can be used in slim-line devices that will be unobtrusive in use. The antennas perform efficiently with a small ground plane, and can even be used on PCBs as small as 65mm. Where the PCB is smaller than 75mm, Antenova provides an additional active tuning circuit to overcome bandwidth reductions.The antennas are designed to work singly or in pairs for MIMO and diversity systems. They have beam steering which gives good isolation and cross correlation and will provide faster downloads in diversity applications.
