G3-PLC is a standards-based power line communications specification which promotes interoperability in

smart grid

implementations worldwide. This system is very elegant and simple to use so it lowers infrastructure costs when compared to other wired and wireless communications networks architecture. It avoids the need to create new communication paths through obstacles such as hills, basements and buildings that block wireless communications therefore, installation and maintenance cost is less. With the help of this technology, companies will be able to attain a low-cost smart grid processes and fulfill the requirement of its client. Main motive of designing G3-PLC, was to meet present and future advanced application and networking layer needs. This protocol can save millions in unneeded network upgrade costs.

For both medium and low-voltage power grids, it provides the best performance and cost efficiency. Its PLC technology minimizes maintenance cost. It supports frequency bands worldwide (10 kHz to 490 kHz). It minimizes infrastructure costs and provides long range communications and can effectively cross MV-LV transformers which reduce need of number of concentrators and repeaters.

It can support sensors and home area network applications and incorporates 6LoWPAN adaptation layer to transmit IPv6 packets over power-line channels. It includes the security mechanisms to protect the grid. It also supports MAC-level security using an AES-128 cryptographic engine. It can function in harsh, noisy environments. The robust mode of this protocol improves communication under noisy channel conditions. It coexists with older technologies also.

It has ability to address the difficult challenges of powerline communications. The unique features of this protocol meet many requirements. The purpose of two layers of forward error correction is for robust data communication in harsh channels. It helps in case of adaptive tone mapping for optimal bandwidth utilization. It helps for channel estimation to select the optimal modulation scheme between neighboring nodes. To improve communication under noisy channel conditions, it has robust mode. IEEE 802.15.4 based MAC layer well suited to low data rates. 6LoWPAN adaptation layer is to transmit IPv6 packets over powerline channels. It supports IPv6 to allow Internet-based energy management systems and applications.

G3-PLC

is called narrowband power-line communication technology that uses the lower frequencies and slow data rates to provide longer distance reach and more reliable service, on the other hand, ordinary Home Plug PLC is intended to support relatively high data rates across short distances within a building. It uses a combination of orthogonal frequency-division modulation (OFDM), forward error correction technology and repetition coding, to support highly reliable data links. These links are of 3 to 5 miles in length across the noisy, challenging environments which are usually found on power lines.

Like the ADSL and VDSL technologies which are usually used to push broadband data across phone lines, it uses orthogonal frequency-division modulation, which creates multiple channels. Its media access control protocol is designed to support mesh network topologies. As there are many PLC devices communicating across a single power line, it uses a multiple access and collision avoidance MAC that listens for both the length of the packet being transmitted and carrier signal.
