How to build IoT Networks?

capillary networks in deployment of IoTWith the introduction of Internet of Things (IoT); networks will be obliged to manage large numbers of heterogeneous devices. There are many ways to connect devices directly to the 5G systems. Moreover, they can also connect with the help of capillary networks using short range radio to extend the 5G network reach. Different radios should be served in the same IoT platform in order to manage efficiently. Smart technology, when deployed, can increase the value of that particular place, for instance, a smart home, a smart office building, a smart bus and so on. According to Ericsson mobility report, until 2021 we will have 15 billion devices will be connected to the network. Some of the devices will be connected to the cellul
ar network while a large part will be accessing radio technologies.

If we want to manage those devices in the similar fashion as that of mobile phones, then we need to use Capillary Gateways. Capillary Gateways acts as a bridge and connects other networks with the 5G system. Capillary Gateways are fixed installations, but a mobile phone can be used to connect to the things nearby. In order to install, configure and manage those devices, the devices need to be automated. By automating the device we mean the system needs to adjust whenever devices are added, lost or moving.

capillary networks in IoT networksIt is concluded that connection to the network plays a vital role in the deployment of IoT. Capillary networks are a smart way to connect the billions of things and devices that need connectivity. In order to optimize the network usage, it automatically manages the connectivity between devices and gateways in the network. This technology supports short-range radio technologies, which are easy to deploy with different topologies, such as star and mesh for example Bluetooth, WiFi and 802.15.4. Moreover, the modern Bluetooth Low Energy mesh technology can be used for capillary connectivity.

We provide an extensive training course about IoT networking. This course covers major aspects of IoT, Machine to Machine (M2M) Communication and Big Data Analytic techniques for IoT.

Towards future challenges for SATCOM-On-The-Move systems

telxperts telecom trainings

b1SATCOM-On-The-Move (SOTM) stands for Satellite Communication on the move, a mobile satellite technology, which is mostly used for military purposes. A vehicle mounted with SATCOM antenna can access satellite or space station even when it is moving. This is an important part of military warfare. There are a number of benefits of deploying this communication technology. Some of the key benefits of SOTM are: it guarantees the effectiveness of warfare, lethality, and survivability. These key benefits have made SOTM a fundamental defense communication system. Initially, it was only used by US military for defense purposes. Later on, it surfaced as a commercial commodity. Hence, commercial satellite industry emerged as a new sector. Figure 1 illustrates a mobile vehicle using satellite technology used in military agencies.

What are the applications of SATCOM on the Move Systems?

When a satellite revolves over the equator of the Earth, it can transmit signals to the extremes of both north and south of a longitude. In summary, when a satellite is hovering along any one longitude of the earth, the station on earth can receive data signals from any point on the ground.   Undoubtedly, with SOTM the defense technology has taken a leap.

What are the future challenges faced by the SOTM Technology?

b2However, there are some potential challenges faced by this technology. Challenges can be based on weight, size, Radio frequency, Protocols of the networking, data rate, and above all vehicle platform dynamics. On the basis of the technical specifications, there are different types of SOTM devices. Portability of the device is the most vital challenge faced by the manufacturers of the SATCOM-enabled products for vehicles. The lighter the device, more acceptability it will get.   Another challenge faced by SOTM is the outage of the radio frequency used for operating and connecting the device for a time period. Interruption can be caused due to bad weather conditions and lack of connectivity inside the tunnels. However, if SOTM device is powerful enough, it can resume operation once you are out of the obtrusion.

Telxperts provides intensive learning to SOTM systems, latest technologies and performance in this training course. This training course focuses on SATCOM services, SOTM fundamentals, techniques, Orbital and spectrum consideration for SOTM and Satellite Communication Evolution to Protected Satellite Communication.

TETRA Radio Evolution Path to 4G LTE

TETRA Radio evolution to 4G LTE is essential in order to enhance the mission critical emergency communication services. A framework for smooth transition of TETRA RADIO to LTE is shown below.

tetra radio evolution to LTE

For smooth transition of TETRA Radio to LTE, initially the critical voice and data messages will run in the narrowband TETRA network, while the high speed non-critical yet secured data will run in the commercial LTE broadband network. A technical architecture of TETRA Radio smooth transition to LTE is shown below:

TETRA Radio Evolution to TETRA 3 Broadband TETRA

Most recently, TETRA standardization bodies have identified user requirements for broadband mission critical data applications which include transfer of multimedia video and photo transfer, location data,  office applications, upload and download of operational information and online database enquiries. As a result, ETSI TC TETRA has initiated a new work item to expand the TETRA standard for transfer of broadband packet data which is scheduled until the end of 2016. Even the whole TETRA industry is extremely uncertain in the moment whether TETRA is already a legacy technology and will shortly be replaced by mission critical LTE.

UK & USA plan to replace TETRA with LTE until 2016 for Critical Communications & Public Safety

Within the next three years, LTE could replace the TETRA system that currently provides mission-critical communications for public-safety agencies and other government organizations in Great Britain, an official said yesterday.

Since 2005, mission-critical communications have been transmitted over the Airwave system—a privately owned TETRA network that covers 99% of the land mass and 98% of the population in Great Britain (England, Scotland and Wales). It serves “all three emergency services and other national users” that pay subscriptions fees, according to Gordon Shipley of the United Kingdom Home Office. Although the performance of the TETRA system is “very good,” it is “extremely expensive” for users, particularly when compared to the plummeting per-minute costs of commercial wireless air time, he said.

In addition, the contracts associated with the Airwave system are scheduled to expire from 2016 to 2020, so the UK Home Office is looking for alternatives, Shipley said.

“Because [the Airwave network is] a TETRA-based system, it’s narrowband data,” Shipley said during the session. “One of the things which has become clear is that the emergency services are now increasingly going broadband services, which can provide even higher speeds. And we need to provide a better, more reliable and secure service for broadband, as well as narrowband voice. So, my program’s responsibility is to find a replacement for critical voice, as well broadband data services, and to do so cost effectively.

“We think, in the UK, that 4G LTE promises significant benefits over the current service that we buy.”

UK officials will conduct a supplier conference next month to get input on the notion of having a public-safety LTE system operational in December 2016, with the entire system transitioned to the 4G technology by 2020, Shipley said.

This development could have an impact in the United States, which is trying to get 3GPP—the global standards body for LTE—to include public-safety requirements such as mission-critical voice in future revisions of LTE that can be implemented in the nationwide broadband network being built by FirstNet, according to Andrew Thiessen, who helps lead the standards effort for Public Safety Communications Research (PSCR), a unit of the U.S. Dept. of Commerce.

“I think it’s imperative that everyone in the audience understand that the United States isn’t the only country that’s actually looking forward to LTE,” Thiessen said during the session. “In many ways, the United Kingdom is actually working faster than FirstNet, looking at a 2016 date for mission-critical voice.”

Of course, one of the key requirements for public safety is mission-critical, push-to-talk voice. A draft set of requirements for push-to-talk over LTE has been distributed to officials in other countries, and the initial response has been positive, Thiessen said.

“We’re actually getting pretty close,” he said. “The comments that we’re getting back are more about clarification of what a particular sentence meant and less so about, ‘Well, we view things very differently.’ Public safety operates fairly similar globally, so push to talk is push to talk, whether it’s TETRA or P25 or whether it’s the United Kingdom or the United States—the expectations of the user community are very similar.”
