The Cellular LTE Category (cat) M1 Netorking Protocol The Future of Cellular Networks for IoT

This blog post explores the emerging role of LTE Cat M1 technology in the Internet of Things (IoT) landscape.

A technology trend that is important in the local area network (LAN) or metro area network (MAN) is cellular data networks or Wireless Local Area Networks (WLAN). The cellular data technology Long Term Evolution (LTE) can deliver speeds up to 300 megabytes per second downstream and 75 megabytes a second upstream, as described by Comer (2014). Part of the LTE standards releases 13 by the 3rd Generation Partnership Project (3GPP) group is category M1.

Internet Routing: Algorithms, Protocols, and Security

Reviewing the Ibternet Routing: Including Algorithms, Protocols, and Security

Explore the world of internet routing: how data packets navigate the complex network, from addressing and protocols to security risks and router trends.

Routing in the Internet and other networks (algorithms, standards, implementations, quality-of-service, security risks, router trends, etc.).

Overview of Routing

Routing is described by Zupan, Ramasamy & Medhi (2010) as enabling the electronic communication network to send packets or units of information from one point to another through a computer network. The network can achieve communications over the network quickly and efficiently.

VoIP's Impact on PSTN, Cellular Networks, and Beyond

Voice Over IP (VoIP) The Future is Now - Impacting PSTN, Cellular Networks, and Beyond

Explore the present state of VoIP (Voice over Internet Protocol), its growing influence on traditional phone lines (PSTN) and cellular networks, and its promising future.

The state of VoIP, its impact on the PSTN and cellular systems, and prediction of its future.

VoIP is a very active. Many houses still have PSTN lines installed at the house. When our family moved back from New Zealand, we didn’t have a landline or PSTN line installed in the house. Only Comcast Internet was installed at the house.

IPv4 Address Exhaustion and the Case for IPv6 Adoption

The Need for IPv6 Adoption

The driving force behind the transition from IPv4 to IPv6 - the exhaustion of IPv4 addresses. Learn about the challenges and the urgency for both industry and government to embrace this critical shift.

The unique characteristics of IPv6 in fulfillment of IPv4's deficiencies, and the challenges confronting both the industry and the government in transitioning from IPv4 to IPv6.

Internet of Things (IoT): Rise and Impact on Daily Life

Internet of Things (IoT) and its Impact on Our Lives

A technological trend that started in its infancy years ago is now proliferating: the use of the Internet of Things (IoT). The term IoT was coined in 1982, as described by research by Farooq, Waseem, Mazhar, Khairi, and Kamal (2015). They describe the first IoT project as a modified Coke machine, which was network-enabled and connected to the Internet. The Coke machine could remotely identify the number of cans in the machine and whether they were cold over the Internet. In 1991, Mark Weiser, a visionary who worked at Parc Xerox, had a contemporary vision of IoT, back then called ubiquitous computing. Weiser envisioned embedding microprocessors in everyday objects so they can communicate information. Kevin Ashton, in 1999, proposed the term “Internet of Things” to describe a system of interconnected devices. The basic idea of IoT is to allow the exchange of information between invisibly embedded different real-world devices around us.

Wired vs. Wireless Data Transmission: Impact and Differences

Thu, 29 Feb 2024 00:00:00 +0000

Gain an Understanding Data Transmission: Wired vs. Wireless and Their Impact

Transmissions are impacted by different problems depending on the method of data transmission. The two types of data communications or transmissions are guided and unguided transmission, as Comer (2014) discusses. Guided media or wire transmissions consist of fiber optic, coaxial cable, and copper or aluminum twisted pair wire, as Varrall (2011) discusses. Unguided media, also known as wireless communication, transports electromagnetic waves with no physical conductor. Instead of physical conductors, the signal is broadcast via air and, therefore, is made accessible to someone having a device capable of receiving them, as Shinde (2000) describes.

DSL, Cable, Fiber & Cellular: Broadband Technologies Guide

What is Broadband? Different Types of Broadband Technologies Explained

What Is Broadband?

Broadband has grown worldwide, promoted by policymakers, network operators, and content providers, but it does not have a single standardized definition worldwide, as described by Kelly (2012). Broadband can mean multiple aspects of the network and services. This may or may not include:

The infrastructure used to deliver broadband services.
High-speed access to the Internet.
Services and applications available via broadband networks.

As Kelly (2012) points out, many countries established broadband based on the speed of services and applications offered on the network. Due to each country’s unique needs and history, including economic, geographic, and regulatory factors, definitions of broadband vary widely.
