Proposed FCC rules may smooth path to 5G wireless tech for US.

Standard

Mobile network traffic is heading in a direction that pleases many in the wireless industry. The Federal Communications on Thursday proposed new rules in wireless frequencies above 24 GHz.

The FCC news release read: “The FCC took steps today to maintain United States leadership in wireless by proposing new rules for wireless broadband in wireless frequencies above 24 GHz. These proposed rules are an opportunity to move forward on creating a regulatory environment in which these emerging next-generation mobile technologies – such as so-called 5G mobile service – can potentially take hold and deliver benefits to consumers, businesses, and the U.S. economy.”

It was previously assumed physical and tech limitations
could not support mobile service in these bands. New tech developments may allow the use of these high frequencies for mobile applications – like 5G service – with significantly more capacity and faster speeds for next generation mobile service.
Building off of years of successful spectrum policy, this NPRM proposes to create new flexible use service rules in the 28 GHz, 37 GHz, 39 GHz, and 64-71 GHz bands. The NPRM proposes to make these bands available using a variety of authorization schemes, including traditional wide area licensing, unlicensed, and a shared approach that provides access for both local area and wide area
networks.

3D printing- Its more than just copying.

Standard

Last week china had made a history by printing 10 houses of 300 feet heights in 24 hrs, using 3D printers , and scientist had made a tumour model for study of typical concepts of this tumour using same technology. Lets know what and how about this technology here.

3D printing is a form of additive manufacturing technology where a three dimensional object is created by laying down successive layers of material. It is also known as rapid prototyping, is a mechanized method whereby 3D objects are quickly made on a reasonably sized machine connected to a computer containing blueprints for the object. The 3D printing concept of custom manufacturing is exciting to nearly everyone. This revolutionary method for creating 3D models with the use of inkjet technology saves time and cost by eliminating the need to design; print and glue together separate model parts. Now, you can create a
complete model in a single process using 3D printing. The basic principles include materials cartridges, flexibility of output, and translation of code into a visible pattern.
3D Printers are machines that produce physical 3D models from digital data by printing layer by layer. It can make physical models of objects either designed with a CAD program or scanned with a 3D Scanner. It is used in a variety of industries including jewelry, footwear, industrial design, architecture, engineering and construction, automotive, aerospace, dental and medical industries, education and consumer products

The model to be manufactured is built up a layer at a time. A layer of powder is automatically deposited in the model tray. The print head then applies resin in the shape of the model. The layer dries solid almost immediately. The model tray then moves down the distance of a layer and another layer of power is deposited in position, in the model tray. The print head again applies resin in the shape of the model, binding it to the first layer. This sequence occurs one layer at a time until the model is complete.
