5G is now and what’s next?
5G deployments have only recently started, and releases beyond R15 will continue to tap into the tremendous potential of 5G. However, as a new generation of cellular technology typically appears every 8-10 years, 6G can be expected around 2030.

Cooling fans consist of an aggregate of airfoils, i.e. blades positioned around a hub that is driven by an electric motor. Due to their airfoil nature, a pressure differential is required across the blades to create the required flow. Therefore, if this pressure differential is disturbed, fan will suffer performance degradation. ...

Fiber optic cable no longer stops at the base of the cell tower. As mobile communication network operators deploy advanced 3G and LTE/4G networks, many are pulling fiber right up the tower. Operators have found that fiber-to-the-antenna (FTTA) architectures offer a number of advantages over legacy coaxial systems, including...

A Heat Sink’s thermal rating can be effectively improved by increasing air flow over its exposed surface area.
Closed extrusion profiles or so called “chimney” designs can arguably improve convection air flow verses “open” profiles by virtue of increased convection air velocity...

There are currently two common approaches to PFC inrush current protection. Such protection caters only for the first instance of power application at the switching on of the AC power.
Faced with higher customer demand and expectations towards higher stability in power supply systems, a new concept is conceived that...

Low-Cost and No-Cost Cooling Best Practices Provide Exceptional ROI for Small to Mid-Size Data Centers
Cooling tends to take a back seat to other concerns when server rooms and small to mid-size data centers are first built. As computing needs grow, increased heat production can compromise equipment performance and...

It is important to first insure the solder is lead-free solder compatible. High tin alloys tend to leach iron causing dissolution of iron and solder contamination. The dissolution can advance to the point of causing micro-cracks and thinning of the walls, eventually resulting in a solder spill.
If a pot is lead-free...
