An antenna converts electric currents into radio waves and vice versa. It is used with radio transmitters and receivers. There are different types of antennas like half-wave dipole, folded, hertz, loop, and turnstile antennas. Antennas are used in radio broadcasting, television, two-way radios, communication receivers, cell phones, and satellite communications. Long Term Evolution (LTE) began as a 3GPP project in 2004 to define a standard for the evolution of UMTS cellular technology. It aims to increase capacity and speed of wireless data networks using new techniques. LTE networks operate on separate wireless spectrum from 2G and 3G since it is incompatible.

Presentation networldm2m sinem_coleriergen_v5
Next generation 5G wireless solutions need to meet the anticipated demands of Machine-to-Machine (M2M) communications in the 2020 era with the total number of devices expected to be about 50 billion for a projected population of around 8 billion according to an Ericsson report. M2M applications can be classified into two categories: Low-cost wide-area and low-latency ultra-reliable M2M. Low-cost wide-area M2M communication requires simple hardware architecture, integration of significant energy efficiency methods and energy harvesting technologies, and enhanced coverage, for such applications as smart metering, fire alarms, sensor networks. Despite LTE enhancements proposed for this class of M2M, however, LTE is not expected to be dominantly used in the near future due to its low coverage and high cost equipment, according to Cisco VNI Mobile, 2015. More research is needed to natively include this M2M class in 5G networks. On the other hand, low-latency ultra-reliable M2M communication requires satisfying strict delay constraint and ultra-high reliability of such applications as platooning of vehicles, robotic control and interaction, remote health care. Controlling the elements in our environment based on the data provided from these machines in this class of M2M applications requires a paradigm shift for control and communication systems with novel strategies for their joint design in beyond 5G networks.
Deployment on Remote Territory (S1-141007)
When an emergency, disaster or any unexpected event occurs, communication infrastructure plays an essential role. For larger effected area, an eNB deployed in high attitude such as high tower can reduce network coverage holes for public safety UEs. Due to deployment on remote territory, the eNB is usually connected to the Evolved Packet Core (EPC) via limited backhaul such as satellite link. Figure 1 depicts a network architecture providing wireless network coverage via satellite backhaul link. In many critical incident related scenarios, the terrestrial infrastructure might be seriously compromised and cannot guarantee reliable communications for rescue teams. During the first 72 hours of a response, communications maybe partially or completely disrupted due to damaged facilities, widespread power outages, and lack of access by restoration crews and equipment to the impacted area. In such cases, the eNB could quickly provide E-UTRAN backhaul link to temporarily replace the ground communication infrastructure, and it can also fast recover the wireless networks to enable critical information access such as the communication for rescue missions or emergency services. Therefore, it can ensure the continued ability to communicate between Public Safety officers within its coverage even if it lost its backhaul link.

Refarming 4 g
LTE Refarming techniques allow mobile network operators to improve the efficiency of their GSM and LTE spectrum usage by rearranging frequencies between the two technologies. There are two main types of refarming: one-off refarming permanently reallocates part of a spectrum block like 1800 MHz from GSM to LTE, while interim refarming temporarily reallocates portions of GSM spectrum as traffic decreases using methods like sandwich frequency allocation that interleaves LTE and GSM bands. Refarming the 1800 MHz band currently used for 2G to 4G LTE can help operators address coverage holes and complement their main 4G spectrum at lower cost due to existing infrastructure.

MSc Project Poster
This document describes a study that investigated beam steering techniques in a multiple input multiple output (MIMO) antenna system using a circular array with six identical antenna elements. The study aimed to alter the magnitude and phase of each antenna element to strategically change the radiation pattern and steer the combined beam in different directions. A genetic algorithm was used to determine the optimized magnitude and phase for each element when steering the beam. Time switching modulation of the elements was also explored as a way to achieve beam steering. Analysis found that adjusting the antenna element parameters allows the beam to be steered to various angles, combating the multipath fading effect.

Performance Analysis of WiMAX and LTE Using NS-2
The increasing use of wireless devices and in particular smart phones has resulted the need for greater capacity
and higher speed than the existing network technologies. Hence, LTE (Long Term Evolution) and WiMAX
(Worldwide Interoper- ability for Microwave Access) became the two leading technologies. Services are
increasingly shifting from voice to data and from circuit-switched to packet-switched ones. Battle between LTE
and WiMAX technologies is already heating up with WiMAX being ahead due to availability of standards
through IEEE 802.16 and is up and running but lacks in substantial roll out plans due to cost. The targets for
LTE indicate bandwidth increases as high as 100 Mbps on the downlink, and up to 50 Mbps on the uplink.
However, this potential increase in bandwidth is just a small part of the overall improvement LTE aims to
provide. This study illustrates the model and representation of LTE links and traffics using NS-2 network
simulator and observation of TCP performance investigated. The Evaluation of the network performance with
TCP is mainly based on congestion window behavior, throughput, average delay and lost packet.

- 1. Introduction An antenna is an electrical device which converts electric currents into radio waves, and vice versa. It is usually used with a radio transmitter or radio receiver. In transmission, a radio transmitter applies an oscillating radio frequency electric current to the antenna's terminals, and the antenna radiates the energy from the current as electromagnetic waves (radio waves).

- 6. History of LTE LTE is a standard for wireless data communications technology and an evolution of the GSM/UMTS standards. The goal of LTE was to increase the capacity and speed of wireless data networks using new DSP (digital signal processing) techniques and modulations. A further goal was the redesign and simplification of the network architecture to an IP-based system with significantly reduced transfer latency compared to the 3G architecture. The LTE wireless interface is incompatible with 2G and 3G networks, so that it must be operated on a separate wireless spectrum.
- 7. History of LTE LTE was first proposed by NTT DoCoMo of Japan in 2004, and studies on the new standard officially commenced in 2005. The LTE standard was finalized in December 2008, and the first publicly available LTE service was launched by TeliaSonera in Oslo and Stockholm on December 14, 2009 as a data connection with a USB modem.
