Data Center Rack Power Distribution Unit (PDU) for Reliable Power Management

A power distribution unit (PDU) is the device used to control electrical power runs in a data center. It is equipped with multiple outputs that are designed to distribute electric power. PDUs are specifically used to supply power to networking equipment and computer racks within data centers. Power management and protection is a key challenge for data centers. PDUs can assist in monitoring and improving their efficiency. They can also prevent equipment failure. 

Deep Dive into Rack Mounted PDUs

These PDUs can be mounted to an equipment rack to control and monitor the power supply to switches, specific servers, and other components. The four fundamental types of rack PDUs are: 

• Basic PDUs: Offer consistent power supply and are commonly available in different mounting types and densities

• Metered PDU: Designed with reliable circuit board and digital display that shows voltage, current, and power levels

• Intelligent PDU: Combination of metered PDU with remote monitoring and controls

• Switch PDU: Capable of remotely controlling each outlet

Intelligent Power Distribution Units

Recently, companies like Siemon and Chatsworth Products have introduced intelligent PDUs for data centers. They can be used as stand-alone units or can be paired with third-party software. APC Corporation’s Switched Rack PDUs provide advanced personalized power controls and dynamic monitoring. Their remote outlet level controls comprise power on/off functionality that can limit unauthorised usage through remote rebooting. Users can also configure, access, and control these PDUs over secure web, command. The new AP8000 series Switched Rack PDUs have features like temperature/humidity sensors, real power monitoring, and IEC receptacle locks.

Can Millimeter Wave (MMW) Technology Make 5G Possible?

Fiber-optic cables were predominantly used for data transmission and online content. However, the need to access Internet at a high speed has led to the development of Millimeter Wave (MMW) technology.

Deep Dive into MMW:-

MMW are the radio waves that operate in the frequencies of 30 gigahertz (GHz) to 300 GHz. This is a step-up from 4G technologies that operate at 6 GHz. Millimeter waves can penetrate thorough most materials, fabrics, and against environmental deterrents like fog or smoke. Apart from the primary uses in satellite and radar systems, MMW is also used in security, astronomy, medical, and telecommunication sectors. Advent of 5G, which promises high data transmission speeds with minimum delay, can be ascribed for this advancement. This technology can power up households in the range of 10 meters to 100 meters using small cells.

High Power Radios:-

Recently, Siklu Communication Ltd., an Israeli company; decided to implement millimeter wave (MMW) technology in Bradford City of the United Kingdom. This technology can power up E-band police radios and transmit electromagnetic waves on an uninterrupted spectrum. It can enable the use of 24 traffic radios and 300 surveillance cameras for security surveillance of the city. The company plans to use 80 GHz E-band radios to create a backhaul wireless network that has data transmission capacity up to 1 GB.

MMW for 5G:-

In April 2017, Facebook, Inc., successfully tested the 5G technology with the help of millimeter wave. It managed to achieve 36 Gbps data transmission with the help of a stationary MMW link from the ground to a circling Cessna plane. Recently, the Transport Security Administration, a division of Homeland Security, used MMW scanners to detect contraband at airports. Millimeter waves also find applications in medical therapy to alleviate pain.

Market Overview:-

According to a report by Grand View Research, Inc.; the worldwide millimeter wave (MMW) technology market is anticipated to attain nearly USD 8.7 billion by 2025. It is expected to register a significant CAGR over the forecast period (2014 to 2025). Rapid technological advancements and the emergence of high-bandwidth applications can impel the expansion till 2025. Increased infrastructural projects to cater to the demand of high-speed networks can further support the market growth.

Telecommunication equipment led the overall market with over 60% share in 2015. Integration at airports can propel the demand in the forthcoming years. Military & defense applications may exhibit over 43% CAGR during the forecast period. Key players operating in the worldwide market are Bridgewave Communications, Inc.; Siklu Communication Ltd.; Aviat Networks, Inc.; and E-band Communications LLC.
