Self-Organizing Network (SON)

2018-05-01T12:44:22+00:00

Self-Organizing Network (SON) Self-Organizing Network (SON) is a set of capabilities defined in the LTE standards to simplify the task of configuring and optimizing LTE networks. SON functions fall into three broad groups: What is a Self-Organizing Network (SON)? Self-configuration enables network components like the Enb to determine key configuration parameters autonomously, identify changes to parameters as a result of network changes (e.g. Automatic Neighbor Relations (ANR)) and to automatically establish signaling interfaces to other network elements. Self-Optimization adjusts parameter settings based on feedback collected over time to fine-tune the transmission parameters to improve performance and reduce failures, and to [...]

Automation: A necessity in 5G

2018-05-01T13:51:53+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. Automation: A necessity in 5G 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 [...]

An Indoor custom solution

2018-05-01T13:53:43+00:00

An Indoor custom solution Special custom solutions may be needed to provide good indoor coverage, high capacity and to reduce overall costs by reusing any existing infrastructure. An indoor custom solution is required to efficiently and effectively provide mobile broadband performance in a multi-story building, small cells can be deployed on different floors in the form of radio nodes. An indoor custom solution (for good indoor coverage, high capacity and reduced overall costs) These radio nodes would be viewed as small remote radio heads. These radio nodes can be connected to an Ethernet network, which also connects to a [...]

Software-Defined Radio Approach

2018-05-01T13:57:52+00:00

Software-Defined Radio Approach In the Software-Defined Radio approach (SDR), signal processing is carried out in software at a general processor instead of special hardware. However, most likely digital to analog and analog to digital conversion and power amplification would be hardware based and thus not be implemented via SDR. RRUs (Remote Radio Units) and BBUs (Baseband Units) are based on Software Defined Radio technology for software-based capacity augmentation and enhancement. SOFTWARE DEFINED RADIO APPROACH A remote Operations Support System (OSS) is typically in Software Defined Radios which is used to manage SDR and carry out upgrade functions. The main advantages [...]

Cloud RAN-Benefits & Challenges

2018-05-01T14:00:45+00:00

Cloud RAN-Benefits & Challenges About Cloud RAN Cloud-RAN combines the baseband processing for multiple sites into a baseband pool, allowing multiple cells to be controlled with fewer processing nodes and greatly reducing the amount of equipment at the cell site itself. Various Cloud RAN-benefits & challenges are also described here: Benefits of Cloud RAN The primary advantage of the C-RAN architecture is the overall reduction in CapEx and OpEx by consolidating and reducing the total amount of baseband equipment needed to handle a given number of cells; and reducing the equipment deployed at each cell site, which in turn reduces the [...]

Journey to Cloud-RAN

2018-05-01T14:04:47+00:00

Journey to Cloud RAN from 4G RAN(Radio Access Network) We are moving towards Cloud RAN from the traditional monolithic base station/Enb architecture. The current eNodeB architecture consists of radio unit and baseband hardware co-located in a cabinet or shelter at the cell site with the IP-enabled BBU (Baseband Unit) sending and receiving traffic to and from the EPC (Evolved Packet Core). The eNBs are deployed at the bottom of the tower with coax feeder cables carrying the RF signal up and down the tower. MOVING TOWARDS CLOUD RAN             In an alternative decoupled architecture, [...]

4G RAN (Radio Access Network)

2018-05-01T14:08:08+00:00

4G RAN (Radio Access Network) There are two different architectures through which the RU (Radio Unit) and the BBU (Baseband Unit) are connected to each other in a 4G RAN (Radio Access Network). The traditional monolithic base station/Enb architecture consists of radio unit and baseband hardware co-located in a cabinet or shelter at the cell site with the IP-enabled BBU sending and receiving traffic to and from the EPC. RADIO ACCESS NETWORK (RAN) IN 4G The eNBs are deployed at the bottom of the tower with coax feeder cables carrying the RF signal up and down the tower. The [...]

Vision of a 5G Network Architecture

2018-05-01T14:16:32+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. VISION OF A 5G NETWORK ARCHITECTURE 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 [...]

4G LTE Network Architecture

2018-05-02T09:29:27+00:00

4G LTE Network Architecture LTE, a 4G wireless technology which has been developed by 3GPP (Third Generation Partnership Project), an industry trade group. The 4G technology LTE that stands for Long Term Evolution has been named so because it represents an evolution from the very basic GSM technology (2G) to 3G standard (UMTS) and the next step comprises of LTE evolving from the third generation of wireless networks. In particular, the factors that led to the emergence of 4G technology are dedicated to the inefficiency of 3G network for supporting the demands of rapidly growing number of users and their expectations of [...]

LTE Broadcast

2018-05-02T09:32:55+00:00

LTE Broadcast One of the key technologies behind the LTE Broadcast is the Single Frequency Network. LTE BROADCAST LTE Broadcast uses the same base stations and radio frequency spectrum as normal LTE transmissions, except that during the broadcast event, a certain portion of radio resources in the cells covering the service area are dedicated to the broadcast service for the duration of the event. The reserved timeslots are used to broadcast the event and the remaining timeslots are used for normal LTE unicast transmissions. During the reserved broadcast timeslots, all participating base stations transmits exactly the same signals at [...]
