Vehicular CrowdCell. Bringing CrowdCell Technology into Vehicles

Small Cell Forum

Vehicular CrowdCell technology brings cellular connectivity to vehicles, allowing them to function as small cells. This improves coverage for passengers inside vehicles and provides ubiquitous high-quality connectivity outside. It also offers network operators benefits like on-demand capacity increases at events through parked vehicles acting as small cells. Simulations show this vehicular small cell concept can gain network capacity, and prototypes are being developed to evaluate real-world performance. The technology was presented at MWC 2016 by researchers from BMW and Vodafone.

Ericsson Microwave Outlook 2016

Ericsson

The document presents Ericsson's outlook on microwave technology and its role in mobile network backhaul. It discusses capacity requirements increasing to 1 Gbps by 2021 and 5 Gbps by 2025. Microwave is well-positioned to support 5G with 10 Gbps capacities and low latency. While fiber substitution is declining, microwave will still connect 65% of cell sites in 2021. E-band and multi-band microwave will be key to meeting the needs of 5G networks. The introduction of 5G will be an evolution using microwave to provide higher throughput and lower latency.

Microwave towards 2020 presentation

Ericsson

Microwave backhaul plays an important role in providing a good user experience and overall network performance. The backhaul capacity needed per base station differs substantially, depending on target data rates and population density. Microwave backhaul technology is able to handle 100 percent of all radio access sites’ capacity needs. This is true for today as well as in 2020, when it will evolve to support multi-gigabit capacities in traditional frequency bands and beyond 10 gigabits in the millimeter wave.

Ericsson Technology Review: Evolving LTE to fit the 5G future

Ericsson

Operators have no reason to be concerned about the future of LTE in a 5G world – its upcoming releases (Rel-14 and Rel-15) are intended to deliver on the most important 5G requirements. They will include enhancements to user data rates and system capacity with FD-MIMO, improved support for unlicensed operations, and latency reduction in both control and user planes. LTE will also be modified to address new use cases such as massive machine type communication, critical communications and intelligent transport systems. Both LTE Rel-14 (scheduled for completion in March 2017) and the strong ambitions for LTE Rel-15 indicate that a smooth transition from LTE to 5G through 5G plug-ins is the best course of action.

IDATE DigiWorld

Portugal Telecom has committed to investing 500 million euros by 2020 to expand its fiber optic network to reach over 5.3 million homes passed, achieving over 90% fiber penetration of Portuguese households. This fiber strategy aligns with the European Commission's goals of universal broadband availability and increasing internet speeds. Portugal Telecom has been a leader in fiber deployment since 2007 and now has over 3 million homes passed with fiber. Investing in fiber is key to developing new services and innovations while future-proofing the network for higher speeds like gigabit connectivity.

gsm operation

keyvan storer

GSM networks divide coverage areas into a hierarchy of locations to efficiently manage subscriber location and enable call delivery. The largest division is the Public Land Mobile Network (PLMN). Within a PLMN are Mobile Switching Center/Visitor Location Register (MSC/VLR) service areas, which are further divided into Location Areas (LA) containing groups of cells. As subscribers move between areas, they perform location updates to inform the network of their position. This allows more efficient paging for call delivery. [END SUMMARY]

LTE LATAM 2015 - Base Station Virtualization: Advantages and Challenges

Alberto Boaventura

This document discusses the advantages and challenges of base station virtualization. Key advantages include improved capacity and coverage through centralized coordination of resources using technologies like Coordinated Multi-Point (CoMP) and enhanced Inter-Cell Interference Coordination (e-ICIC), which can increase system capacity up to 30 times. A centralized architecture is also well-suited for handling non-uniform traffic loads through dynamic load balancing across baseband units. However, challenges include requirements for additional spectrum, new infrastructure investments, interference mitigation techniques, and ensuring backhaul network capacity scales with increasing cell densities.

LPWAN technology overview

Jisc

This document provides an overview of Low Power Wide Area Networks (LPWAN) technologies. It discusses the key characteristics of LPWAN such as operating at a long range of up to 10km using little battery power and transmitting small amounts of data. It summarizes the major LPWAN technologies including LoRaWAN, Sigfox, NB-IoT and LTE-CAT M1. It also outlines the growth in the number of LPWAN devices, networks and applications. Examples of common LPWAN uses cases like smart metering and asset tracking are also highlighted.

Location based advertisement system with voice announcement system

Subhash Suman

This document describes a location-based advertising system using GPS and voice announcements. The system uses a GPS receiver to identify the device's current location by latitude and longitude. This location is compared to stored locations in a microcontroller's database. When a matching location is found, a voice-based advertisement is triggered. The location coordinates are also continuously displayed on an LCD. The system provides automatic location identification, location-based advertising, and a way to dynamically store locations.

AUTOMATIC VEHICLE ACCIDENT INFORMATION BY SMS SYSTEM (AVAIS SYSTEM) Gps gsm a...

kailashgavare

This is the GPS based vehicle accident detection and security system. A GPS receiver must be receive the signal of satellites to calculate a position (latitude and longitude) and send the data to Micro controller. All function is done by Micro controller. MCU read the information of GPS Modem and display on LCD. In the vehicle, has different sensor’s like, Fire Detection, CNG gas Leakage, Smoke detector or vibration sensor etc. When any sensor detected in vehicle, MCU send location and sensor status VIA SMS to user. In this project PIC microcontroller is used for interfacing to various hardware peripherals. The current design is an embedded application, which will continuously monitor a moving Vehicle and report the status of the Vehicle on demand. For doing so an PIC16Fxxx microcontroller is interfaced serially to a GSM Modem and GPS Receiver. A GSM modem is used to send the position (Latitude and Longitude) of the vehicle from a remote place. The GPS modem will continuously give the data i.e. the latitude and longitude indicating the position of the vehicle. The GPS modem gives many parameters as the output, but only the NMEA data coming out is read and displayed on to the LCD. The same data is sent to the mobile at the other end from where the position of the vehicle is demanded. An MCU Internal EEPROM is used to store the mobile number

GLONASS and GSM based Vehicle Tracking System

IRJET Journal

1. The document describes a GPS and GLONASS-based vehicle tracking system designed for tracking vehicles transporting radioactive cobalt-60 sources in India. 2. The system uses a standard GPS/GLONASS module to obtain location coordinates via satellite signals and transmits the location data via GSM SMS messages to a vehicle tracking server. 3. The tracking system is housed in a single module containing a GPS/GSM module, microcontroller, battery, charging system, antennas, and SIM card slot. It obtains location after a set time interval and sends the coordinates via SMS to monitor vehicle location in real-time.

Examining the Role of SDN and NFV in the Move Towards LTE-A and 5th Generation

Alberto Boaventura

This document discusses the roles of SDN and NFV in enabling 5G/LTE-A networks. SDN and NFV can help address challenges of increasing traffic capacity demands through network functions virtualization and software-defined control of network resources. This allows dynamic allocation of resources through network slicing and virtualization. SDN control can also help with interference avoidance through coordination of resources across virtual base stations in a centralized RAN architecture. Overall, SDN and NFV provide mechanisms for elastic, on-demand provisioning of network capacity needed to support the high traffic demands of evolving 5G technologies.
