Mobile data usage is growing exponentially driven by smartphones, but most data usage occurs indoors where wireless coverage is poor. Traditional macro-cellular networks cannot meet long-term mobile broadband demands. Femtocells provide a solution by creating "personal" indoor base stations that improve coverage and capacity through spatial reuse. Key challenges include interference avoidance between macrocells and femtocells as well as developing applications enabled by femtocell awareness of mobile and home networks. Femtocells promise benefits for both consumers through improved in-home experience and operators through lower costs and new services.

5G is the fifth generation technology standard for cellular networks, which cellular phone companies began deploying worldwide in 2019, the planned successor to the 4G networks which provide connectivity to most current cellphones.
Digital Nasional Berhad (DNB) has been established to accelerate the availability and adoption of 5G to support the transformation of Malaysia. The rollout of the 5G network has kicked off with the provision of 5G coverage in the Malaysian capital. This 5G network, will empower Malaysians to embrace the new digital economy.

What Makes 5G Network Different - Digital Nasional BerhadDigitalNational
5G network is here and set to change our world for the better. It is true that 5G represents the fifth generation of mobile networks, but it is so much more than just another ‘G’. Read more
5G Technology stands for 5th Generation Mobile technology which was started from late 2010s.
Complete wireless communication
with almost no limitations.
It is highly supportable to WWWW
(Wireless World Wide Web).
Mobile communication has become more popular in last few years due to fast revolution in mobile technology. This revolution is due to very high increase in mobile customers. This revolution is from-
1G - the first generation
2G- the second generation
3G - the third generation
4G - the fourth generation and
5G - the fifth second generation
5G is the 5th generation mobile network. It is a new global wireless standard after 1G, 2G, 3G, and 4G networks. 5G enables a new kind of network that is designed to connect virtually everyone and everything together including machines, objects, and devices.

In this presentation, we embark on a journey through the evolution of cellular networks, tracing their roots from 1G to the current pinnacle of technology, 5G. We delve into the intricacies of 5G, exploring its foundational principles, technical workings, and the myriad advantages it brings, from lightning-fast data speeds to enabling groundbreaking applications in augmented reality, the Internet of Things, and beyond. However, no exploration of 5G is complete without addressing concerns and misconceptions. We confront conspiracy theories surrounding 5G, including alleged health risks and unfounded associations with the COVID-19 pandemic. By the end, participants will gain a holistic understanding of 5G's transformative potential, appreciating its benefits while dispelling myths that may cloud its advancement.
Seminar Presentation on Femtocell Technology
A femtocell is a small device that is used to improve
wireless coverage over a small area, mostly indoor. It is a small cellular base station, also
called a wireless access point that connects to a broadband Internet connection and broadcasts
it into radio waves in its area of coverage.
5G is the short for fifth generation, a mobile broadband technology that is in the early stages of works and likely to be in place six to seven years from now.
A 5G network will be able to handle 10,000 times more call and data traffic than the current 3G or 4G network.
Data download speeds on 5G networks are likely to be several hundred times more than 4G.
5G mobile technology will change the means to use cell phones within very high bandwidth.
Mobile IP1) Mobile IP(MIP) is an Internet Engineering Task Force(.pdfanandhomeneeds
Mobile IP:
1) Mobile IP(MIP) is an Internet Engineering Task Force(IETF) standard communications
protocol.
2) This is designed to allow mobile device users to move from one network to another while
maintaining a permanent IP address.
3) Mobile IP for IPv4 is described in IETF RFC 5944 and extensions are defined in IETF RFC
4721.
4) Mobile IPv6 the IP mobility implementation for the next generation of the Internet Protocol
IPv6 is described in RFC 6275.
Advantages of using Mobile IP
• It allows fast, continuous lowcost access to corporate networks in remote areas where there
is no public telephone system or cellular coverage.
• It supports a wide range of applications from Internet access and email to ecommerce.
• Users can be permanently connected to their Internet provider and charged only for the data
packets that are sent and received.
• Lower equipment and utilization costs for those requiring reliable highspeed data connections
in remote locations worldwide.
• A user can take a palmtop or laptop computer anywhere without losing the connection to the
home network.
• Mobile IP finds local IP routers and connects automatically. It is phonejack and wirefree.
• Other than mobile nodes/routers, the remaining routers and hosts will still use current IP.
Mobile IP leaves transport and higher protocols
unaffected.
• Authentication is performed to ensure that rights are being protected.
• Mobile IP can move from one type of medium to another without losing connectivity. It is
unique in its ability to accommodate heterogeneous
mobility in addition to homogenous mobility.
Disadvantage of Mobile IP
• There is a routing inefficiency problem caused by the “triangle routing” formed by the home
agent, correspondent host and the foreign agent.
• Security risks are the most important problem facing Mobile IP. Besides the traditional security
risks with
IP, one has to worry about faked careof addresses.
• Another issue related to the security is how to make Mobile IP coexist with the security
features coming in
use within the Internet.
Characteristics of Mobile IP (Baseline Requirements)
• Compatibility: A new standard cannot require changes for applications or network protocols
already in use.
• Transparency: Mobility should remain “invisible” for many higher layer protocols and
applications.
• Scalability and efficiency: Introducing a new mechanism into the Internet must not degrade the
efficiency of the network.
• Security: All messages used to transmit information to another node about the location of a
mobile node must be authenticated to protect against remote redirection attacks
The Mobile IP in Wireless Networks
• new proposed standard of the IETF designed to support mobile users .
• new Internet standard for the Web and private networks.
• currently two standards one to support the current IPv4 one for the upcoming IPv6.
• One of the big requirements on the new standard is that it should support both ordinary and
wireless network
• The big issue is.
