Incorporating smart building technology into your business is becoming more popular as more businesses realize its benefits. Buildings that use smart technology to control various systems are called smart buildings.

Internet of Things, artificial intelligence, machine learning, and data analytics can be used in smart buildings to optimize performance and reduce energy consumption. Smart buildings can adapt to changing weather conditions to provide comfortable and efficient living environments.

Define Smart Buildings

Smart buildings optimize energy efficiency, reduce environmental impact, and improve operational efficiency while responding to the needs of their occupants.

As part of smart buildings, various technologies are used, including sensors, automation, and data analysis, to make the building more comfortable, safe, and efficient.

In smart buildings, various building functions are monitored and controlled, including heating, cooling, lighting, security, ventilation, etc. Building managers can monitor and manage building operations in real-time by connecting these systems to a cloud-based centralized control system.

Smart Buildings Key Features

Energy Monitoring System (EMS)

Smart buildings are also equipped with energy monitoring systems, or EMSs. Energy consumption is monitored throughout the building using sensors, which provide real-time data. By analyzing these data, building managers can identify areas of waste and make adjustments to improve efficiency. It is possible to use this data to help building owners optimize their energy production and reduce their dependence on the grid.

Fault Detection & Diagnosis (FDD)

Diagnostics of faults in a building's systems are possible through fault detection and diagnosis or FDD technologies.

The FDD analyzes equipment and systems for abnormalities by installing sensors throughout the building. Building managers or maintenance staff can automatically be notified when a fault is detected, allowing them to address the issue quickly.

There are many applications for FDD, such as HVAC systems, where faults can result in energy wasted and reduced performance. FDD allows energy consumption to be reduced and costly repairs can be avoided by detecting and fixing faults early.

Brazil to re-allocate 2.6 GHz spectrum Inhand Networks

www.inhandnetworks.com

The Brazilian telecommunications regulator ANATEL has adopted spectrum re-farming of the 2.6GHz band, allowing the use of this spectrum for deployment of next-generation Mobile Broadband services.

Congratulating ANATEL, GSMA said, ANATEL's decision to re-allocate spectrum in the technology neutral 2.6 GHz band to support the nationwide deployment of next-generation Mobile Broadband services will provide mobile operators in Brazil with a clear future investment path for the country's mobile network infrastructure.

ANATEL's decision is also consistent with the ITU's Option 1(i) for international 2.6GHz spectrum harmonisation, currently being followed by the majority of mobile operators worldwide. Spectrum harmonisation in this band means that Brazilian operators will benefit from the vast economies of scale that the GSM ecosystem offers, driving down equipment and device costs, which can be passed on to customers, said GSMA in a statement.

"Other countries such as Mexico, Nigeria, Saudi Arabia and South Africa would benefit from similar rulings whereby existing spectrum is intelligently re-allocated for Mobile Broadband deployment as part of global spectrum harmonisation, driving widespread socio-economic benefits for governments and consumers and generating additional revenue for operators," said Tom Phillips, Chief Government and Regulatory Affairs Officer, GSMA.

Brazil's 2.6GHz spectrum band had previously been allocated to MMDS operators to support pay-per-view TV services. This ruling will not impact these operators, who will keep 70MHz(ii) of spectrum (50 MHz of TDD and 2 X 10 MHz of FDD). ANATEL's decision does mean that the country's mobile operators will benefit from the majority of this spectrum, stating that 120MHz should be auctioned off by mid-2013(iii). Mobile operators in Brazil also have the option of deploying LTE immediately, should they acquire an MMDS operator currently holding spectrum licenses.

Ensuring the necessary spectrum is available will pave the way for Brazilian operators to follow the clear upgrade path from existing HSPA technology to LTE.
