Caltech develops optical switch in lithium niobite

A team led by Alireza Marandi, assistant professor of electrical engineering and applied physics at Caltech, has developed an all-optical switch in lithium niobate with the potential to perform optical signal processing.

The research, which was published in the journal Nature Photonics on July 28, studies how pulses of light can be temporarily confined in a tiny space in the substrate. 

The net result is the creation of a nonlinear splitter in which the light pulses are routed to two different outputs based on their energies, which enables switching to occur in less than 50 femtoseconds (a femtosecond is a quadrillionth of a second).

FCC commences 5G mid-band spectrum auction

The FCC opened bidding in its latest mid-band spectrum auction at 10am on Friday, July 29.

Auction 108 makes available 8,017 new flexible-use, county-based overlay licenses in the 2.5 GHz band. These licenses are in areas with unassigned 2.5 GHz spectrum— mostly rural parts of the country—following disposition of applications filed in the Rural Tribal Priority Window, which has to date resulted in the grant of 335 licenses to serve Tribal communities.

“We all know there are gaps in 5G coverage, especially in rural America, and this auction is a unique opportunity to fill them in,” said FCC Chairwoman Jessica Rosenworcel. “I am grateful to the teams that have worked so hard to both stand up this auction and ensure the success of our efforts to make these airwaves available to Tribes to support wireless service in their communities”

Auction 108 utilizes a “clock-1” auction format similar to the clock phase of past FCC auctions, but rather than offering multiple generic spectrum blocks in a category in a geographic area, it will offer only a single frequency-specific license in a category in a county. The new flexible-use geographic overlay licenses in the 2.5 GHz band (2496-2690 MHz) must protect the operations of incumbent licensees within the auctioned areas, including any licensees that receive their licenses through applications filed in the Rural Tribal Priority Window.

FCC incentivizes to open underutilized spectrum for rural carriers

The FCC voted to create an Enhanced Competition Incentive Program (ECIP) to establish incentives for wireless licensees to make underutilized spectrum available to small carriers, Tribal Nations, and entities serving rural areas. The new program encourages licensees to partition, disaggregate, or lease spectrum to better match available spectrum resources with entities that seek to provide needed services to under-connected communities.  Under...

Rosenworcel proposes minimum of 100/20 and goal of 1,000/500

FCC Chairwoman Jessica Rosenworcel is proposing a new the national standard for minimum broadband speed of 100 Mbps for download and 20 Mbps for upload. She is also proposing for the FCC to set a separate national goal of 1 Gbps/500 Mbps for the future. “The needs of internet users long ago surpassed the FCC’s 25/3 speed metric, especially during a global health pandemic that moved so much of life online,” said Chairwoman Rosenworcel.  “The...

FCC begins Mandatory Disaster Response Initiative for mobile operators

The FCC launched a Mandatory Disaster Response Initiative (MDRI) aimed at ensuring that the nation’s communications networks are more available in the midst of disasters and other emergencies. MDRI will leverage the industry-developed Wireless Network Resiliency Cooperative Framework, which is a voluntary agreement among a limited group of facilities-based mobile wireless service providers.   This agreement, which the Commission endorsed...

Meta builds out its Sarpy Data Center in Nebraska

Meta is building a new data hall at its Sarpy Data Center campus in Springfield, Nebraska. This will bring the campus to a total of nine buildings and 4 million-square-feet.

The Sarpy Data Center will continue to be supported by 100% renewable energy, made possible through our investments in wind energy, including a wind farm in Dixon County, Neb. Meta reached net zero emissions for its operations in 2020.

The facility was originally called the Papillion data center but was renamed Sarpy Data Center campus in 2021.

Telit to acquire Thales' cellular IoT business

 Telit agreed to acquire Thales' cellular IoT products division, which offers a portfolio of cellular wireless communication modules, gateways, and data (modem) cards, ranging from 4G LTE, LPWAN to 5G. 

Thales' cellular IoT module business, with approximately 550 employees across 23 countries, services many of the world's top brands. It generated sales of more than €300 million in 2021.

The combined company will be called Telit-Cinterion and based in California. To sharpen focus on Industrial IoT, Telit Cinterion plans to spin off and manage separately the automotive IoT unit after closing.

Paolo Dal Pino, Telit's CEO, remarked: "Innovation, scale and efficient IoT solutions are key for success. This transaction with Thales is arguably the most impactful one for Telit competitiveness. While it will boost our ability to address customer needs more precisely from a richer portfolio, it will also enable us to deliver all new offerings derived from the experience, expertise, and the DNA of two companies that have made security and quality part of their brand promise from the very beginning."

Philippe Vallée, Thales's EVP Digital Identity and Security, added: "The Thales and Telit combination brings together complementary strengths. The business will provide a unique value proposition in a highly competitive global IoT market and will allow Thales to focus its investments on its three core activities in aerospace, defence and security and digital identity and security. The new combination will rely on a unique set of expertise brought by Thales and Telit employees. It will also benefit from leveraging both companies' strong and complementary product portfolio and Thales's experience in cellular connectivity."
