Machine Type Communication (MTC)

2019-02-11T19:04:29+00:00

Machine Type Communication (MTC) Machine Type Communication (MTC) Wireless subscribers use 4G LTE networks in a variety of ways. For example, voice calls, emails, web browsing, streaming video, messaging and gaming are quite popular. In general, the majority of communication methods in use today involve human interaction.  5G networks are expected to serve communication between machines in addition to human interaction. Several studies predict tens of billions of devices to be connected to some IP-based network. Hence, wireless networks need to support machine communications for massive Internet of Things (IoT). For e.g., factory automation of manufacturing, surveillance cameras, smart [...]

Artificial Intelligence (AI) in Travel & Hospitality Sector

2018-11-28T17:23:45+00:00

Artificial Intelligence (AI) in Travel & Hospitality Sector Artificial Intelligence (AI) in Travel & Hospitality Sector AI in the form of virtual assistants, chatbots and robots is increasingly being employed across the travel and hospitality sector. Chatbots are amongst the most prominent applications of AI in travel. Industry players are either building their own customized chatbots, or using interfaces powered by established messaging applications. For instance, an Indian metasearch engine recently launched an AI-based chatbot, which can answer queries related to travel planning and booking, including what to do in a city. The company also plans to introduce a [...]

Automation: A necessity in 5G

2018-10-06T19:52:35+00:00

Automation: A necessity in 5G Automation: A necessity in 5G- 5G networks are expected to use numerous small cells. Due to the massive small scale deployment, automation is the only practical way of configuring and then optimizing small cells. In addition to managing parameters of a cell, relations between a cell and its neighbors also need to be managed automatically. Furthermore, intelligent and automatic tuning of operational parameters can help improve the spectral efficiency of a 5G network. For example, to efficiently and effectively provide mobile broadband performance in a multi-story building, small cells can be deployed on different floors [...]

Vision of a 5G Network Architecture

2018-09-27T05:50:19+00:00

Vision of a 5G Network Architecture In the future of wireless, a significant increase is expected in devices, device types, connections, applications data traffic and signaling. The traffic is expected to be bursty while IoT devices require connectionless services. The 5G network architecture will be designed after considering all these factors. This requires the ability to program the network to support different applications via Network Functions Virtualization (NFV) and Software-Defined Network (SDN). The goal is to allow operators to rapidly deploy services and solutions. The enhanced network architecture provides ultra-low user plane latency and ultra-broadband user plane. The MME-like functions [...]

Carrier Aggregation Across Cell-Sites in 5G

2018-09-26T14:13:24+00:00

Carrier Aggregation Across Cell-Sites in 5G One of the major features of 5G is carrier aggregation across cell-sites in 5G networks, which allows mobile network operators to combine a number of separate LTE carriers. This enables them to increase the peak user data rates and overall capacity of their networks and to exploit fragmented spectrum allocations. In case of LTE Advanced, Carrier Aggregation can be applied to either the FDD or TDD variants of LTE and it can be used to combine carriers whether or not they are contiguous or even in the same frequency band. Ultimately, the aim is [...]

Multi-Cell Collaboration for Radio Resource Management in 5G

2018-09-26T14:05:22+00:00

Multi-Cell Collaboration for Radio Resource Management in 5G Multi-cell collaboration for radio resource management in 5G: In a typical scenario, the eNodeBs operate relatively independently and control the radio resources of their respective cells. Each eNodeB aims to optimize its performance and tries to provide promised QoS to the users in its cells. Such distributed control of resources makes the network scalable and reduces the overall signaling delays and decision-making delays. However, it is possible to enhance the performance of the overall network via collaboration. In a Collaboration scenario, eNodeBs in a given neighborhood exchange information about utilization of radio [...]

Rising Need of HetNet and Small Cells for 5G

2018-09-26T13:45:50+00:00

Rising Need of HetNet and Small Cells for 5G The importance of small cells cannot be emphasized enough for emerging networks. There is a rising need of HetNet and small cells for 5G networks. Emerging 5G networks need to meet  very high performance goals of throughput (e.g., area throughput of 10 Mbps per square meter and connection density of one million devices per square kilometer area). Hence, densification is quite critical to emerging networks. A heterogeneous network with more number of small cells would be needed. Instead of a distributed radio network where radio resources are managed locally by base [...]

Traditional Duplexing vs. Flexible Duplexing in 5G

2018-09-25T18:48:24+00:00

Traditional Duplexing vs. Flexible Duplexing in 5G Traditional Duplexing vs. Flexible Duplexing in 5G: Traditional duplexing techniques are Frequency Division Duplex (FDD) and Time Division Duplex (TDD). Frequency is divided to separate UL & DL. UL Bandwidth and DL Bandwidth will always stay same, so called as Symmetric communication. Also called as ‘Paired Communication’. FDD uses two different frequencies for the downlink and the uplink for simultaneous communication where the UL Bandwidth and DL Bandwidth will always stay same, so called as ‘Paired Communication’. In contrast, TDD uses only one frequency channel and shares this frequency channel between the downlink [...]

Benefits of Massive MIMO in 5G

2018-09-25T18:20:51+00:00

Benefits of Massive MIMO in 5G Benefits of Massive MIMO in 5G: MIMO uses numerous antennas at the base station and several antennas at the UE. Higher frequencies enable more antennas to be placed in a given amount of space. Groups of antennas can be used to implement higher-dimension spatial multiplexing. For example, if a base station has 64 antennas, four of these antennas can be utilized to implement (4*4) MIMO for a UE that has four receive antennas. The availability of numerous antennas at the base station enables the base station to create narrow beams that can be created [...]

Higher Frequency Bands in 5G Higher Frequency Bands in 5G: MIMO uses numerous antennas at the base station and several antennas at the UE. Groups of antennas can be used to implement higher-dimension spatial multiplexing. For example, if a base station has 64 antennas, four of these antennas can be utilized to implement (4*4) MIMO for a UE that has four receive antennas. The availability of numerous antennas at the base station enables the base station to create narrow beams that can be created in three dimensions instead of just two dimensions. 2D beamforming separates users in the horizontal plane [...]
