Today’s fast growing world needs faster communication. Technology is making rapid progress and is making many things easier. The innovative idea’s that have been emerged from the tender minds of young scientists led to the evolution of many techniques where our present topic -˜MOBILE COMPUTING’ fits in. “MOBILE COMPUTING- and COMMUNICATIONS is a major part of wireless communication technology. Mobile computing in means computing done by intermittently connected users who access network resources. It requires a wireless medium such as cellular radio, radio nets and low orbit satellites. It incorporates wireless adapters using cellular telephone technology to connect portable computers with the cabled network. Mobile voice communication is widely established throughout the world and had a very rapid increase in the number of subscribers to the various cellular networks over the last few years. An extension of this technology is the ability to send and receive data across these cellular networks. This is the principle of mobile computing. Mobile data communication has become a very important and rapidly evolving technology as it allows users to transmit data from remote locations to other remote or fixed locations. This proves to be the solution to the biggest problem of business people on the move mobility. We in this paper describes about the Mobility Services Architecture which supports applications by a middleware stub. Mobile Computing evolved during the last few years as a result of shrinking portables and growing wireless networks. It enlarges the usability of computers, but raises demanding challenges.

5G network installation involves months of planning and preparation even before the first radio or antenna is connected.
The technical support for 5G concept is from massive MlMO technology. Massive MIMO technology is an upgraded version of traditional MIMO technology
The basic principle of massive MIMO technology is to achieve gain improvement in the target direction through weighted synthesis, thereby enhancing the target signal performance, reducing the gain in non-target directions, and even zeroing the interference direction.
5G does also require additional CIPRI and optical Fiber testing and installing. Latest test instruments can combine OTDR, Spectrum Analyser, Antenna analyser and 10G Testing in one box. MPO connectors and other fiber connectors could be checked by Fiber Inspection Probes to assure proper connection for fiber links.

Abstract—Wireless Communication is the most important
development of its time. A decade ago who would have thought
of there would be no hassle of the wires and technology would
actually become wireless. The aim of the report is to compare
how wireless technology has been developed with time and now
how fast and easy it is compared to its past position. The results
of the research show that engineers make advancements and
surprise the audience. They are and will always surprise the
new generation of their time and that is also the future vision of
Microsoft.
I. INTRODUCTION
M ICROSOFT is one of the few corporations, whichare always found in the list of the leaders of the
computer technology. William H. Gates established it in 1975
and since then Microsoft has been known for its inventions
and innovations and now recently they put forward their
future vision of productivity. According to the videos they
released, technology is everywhere. They believe that within
5-10 years everything will be replaced by technology, which
would be fast and user friendly. A decade ago who would have
thought that there would be a time when technology would
be wireless. Wireless communication is when information
or any sort of data is being transferred from one point to
another without any physical attachment. Distances can be
short, such as a few meters for television remote control, or
as far as thousands or even millions of kilometers for deep-
space radio communications. It encompasses various types
of fixed, mobile, and portable applications, including two-
way radios, cellular telephones, personal digital assistants, and
wireless networking. Other examples of wireless technology
include GPS units, garage door openers, wireless computer
mice, keyboards and headsets, headphones, radio receivers,
satellite television, broadcast television, broadcast television
and cordless telephones. [1, ]
II. MOBILE TELECOMMUNICATIONS
A. Advancement of Mobile Wireless Internet
Advancement is a gradual process. Wireless communication
is on the process for some time now. 2G were developed
for voice communications. It was for sending data over 2G
channels by using modem. It provided adat rates in the order
of 9.6 kbps. Then after a while 3G systems were introduced.
Its goal was for voice and data transmission, multi-megabit
Internet access, voice-activated calls, and multimedia content.
CDMA system evolved to CDMA2000. GSM, IS-136 and
PDC evolved to W-CDMA (wideband CDMA)(also called
UMTS). It had up to 2.048 Mbps data-rates. 4G mobile
technologies is the mobile race to innovation. Wireless systems
were further improved and 4G systems came into being. It is
best known for its seamless mobility (roaming). It allows to
roam freely from one standard to another, ...

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.
Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

Wireless Communications
Wireless communications are everywhere. People around the world regularly send and receive
messages wirelessly, that is transmitted through the air. Three types of wireless communications include
wireless messaging services, and wireless Internet access points, and global positioning systems.
People use mobile phones, PDAs, and other mobile devices to access text messaging instant
messaging and picture messaging services (Davies 34-42). Through text messaging services, users send
and receive short text messages, which usually consist of fewer than 300 characters. Wireless instant
messaging is an internet communications services that allows a wireless mobile devices exchange
instant messages with one or more mobile devices or online personal computers. Users send graphics,
pictures, videos clips, sound files, and short text messages with picture messaging services 1
In many public locations, people connect to the Internet through a wireless Internet access point
using mobile computers and devices. Two types of wireless Internet access points are hot spots and 3-G
networks. A 3G network, which uses cellular radio technology, enables users to connect to the Internet
from end to end a mobile phone computer equipped with an appropriate PC Card. A hot spot is a
wireless network that allows mobile users to check e-mail browse the Web, and access any Internet
service- as long as their computers or devices have the proper wireless capability.
A global positioning system (GPS) is a navigation system that consists of one or more earth
based receives that accept and analyze signals sent by satellites in order to determine the receiver’s
Podpora and Ruiz indicates that some messaging services use the tem, video messaging to refer separately to the
capability of sending video clips (79-82)

Geographic location, according to Shelly and Cashman (How a GPS Works). A GPS receiver is a
handheld, mountable, or embedded device that contains an antenna, a radio receiver, and processor.
Many mobile devices, such as mobile phones and PDAs, have GPS capability built into the devices
Mobile users communicate wirelessly messaging services, wireless Internet access points, and
global positioning systems. Anyone can take advantage of wireless communications using mobile
computers and devices
