CFTXOP are used for implementing TDMA Channel Access for specific applications that require quality of service (QoS) guarantees. Contention-Free Transmission Opportunities (CFTXOP), which have a fixed duration and are allocated to a specific pair of transmitter and receiver.

The G.hn Media Access Control is based on a time division multiple access (TDMA) architecture, in which a 'domain master' schedules Transmission Opportunities (TXOPs) that can be used by one or more devices in the 'domain'. The maximum QAM constellation supported by G.hn is 4096-QAM (12-bit QAM). In G.hn each one of the sub-carriers is modulated using QAM. OFDM systems split the transmitted signal into multiple orthogonal sub-carriers. G.hn includes mechanisms to avoid interference with legacy home networking technologies and also with other wireline systems such as VDSL2 or other types of DSL used to access the home. G.hn includes the capability to notch specific frequency bands to avoid interference with amateur radio bands and other licensed radio services. G.hn specifies a single physical layer based on fast Fourier transform (FFT) orthogonal frequency-division multiplexing (OFDM) modulation and low-density parity-check code (LDPC) forward error correction (FEC) code. Technical specifications Technical overview Layer 2 configuration management protocol LCMP.Neighbouring domains interference mitigation (distributed NDIM).This new feature was approved in March 2012 under G.9963 Recommendation.Īmendments to the main G.9960/ G.9961 added new functionalities to the base standard: The ITU-T extended the technology with multiple input, multiple output (MIMO) technology to increase data rates and signaling distance. Key promoters CEPCA, HomePNA, and UPA, creators of two of these interfaces, united behind the latest version of the standard in February 2009.

The Data Link Layer (Recommendation G.9961) was approved on June 11, 2010. ITU-T Recommendation (the ITU's term for standard) G.9960, which received approval on October 9, 2009, specified the physical layers and the architecture of G.hn. G.hn was developed under the International Telecommunication Union's Telecommunication Standardization sector (the ITU-T) and promoted by the HomeGrid Forum and several other organizations.
