Emerging Low Power Technologies

Low Power Wide Area NetworksTo support the further growth and development of the Internet of Things (IoT) the mobile industry is developing and standardising a new class of GSM technologies focused on IoT, which is called Low Power Wide Area (LPWA) networks. These technologies enable the new IoT services to expand and be more competitive and hence that is why it has the following advantages.

5G: How it will change our lives

5g technologyThe advent of 5G technology signifies the start of an even more globally connected society, a completely digital society. This technology, expected to be implemented in 2020, will change the way we interact with each other and objects, allowing us to be permanently connected, both to other people, and to everyday objects like the refrigerator or car.The Internet of things boom is imminent, and depends directly on the evolution of communications networks and the arrival of 5G technologies.

The near future of Wireless technology : Wi-Fi 802.11ax

wireless technologyEach time we download an application, browse the Internet, read an email or watch something on YouTube on our smartphones, we’re using some type of wireless technology. For mobile networks this means 3G or 4G LTE. However, when it comes to our home or work environment, we’re probably using Wi-Fi.

From 802.11a, endorsed in the 90s (reaching speeds of up to 54 Mbps over 5 GHz radio waves) to the current range of 802.11ac routers (up to 1.3 Gbps over a 5 GHz band and 450 Mbps over 2.4 GHz), many things have changed. (more…)

The role communications play in transport and the custody of securities

ipsecDespite the potential symbiosis between transport in armored cars and Information and Communication Technologies (ICT), two factors have prevented both sectors from making the most of the opportunities available. The first has to do with the limited bandwidth cellular technologies offered up until recently; the second with the lack of integration and interoperability of existing services (GPS, video, communications, etc.). These two factors have helped perpetuate this problem, which is also present in public and private security forces.

What is LTE Advanced?

lte advancedWhat we commonly call 4G+ is really LTE Advanced, a standard based on the 3GPP Release 10 norm, passed in March 2011.

It is, basically, a number of improvements that enhance the LTE (Long Term Evolution) standard stemming from the 3GPP Release 9 norm.

The main goal of the LTE Advanced standard is to improve LTE and broaden its capacity. That is, to guarantee a higher number of simultaneous users benefit from a better service.

The following is needed to achieve this goal:

  •  Better spectral efficiency, of up to 30bps/HZ.
  •  Variable bandwidth, capable of ranging from 20MHz to 100MHz by adding up to 5 20MHz carriers.
  •  Better use of antennas with 8×8 MIMO technology for downstream operations and 4×4 MIMO for upstream ones.

This means peak upload speeds of 1.5Gbps and download speeds of 3Gbps can be achieved.

Other standard improvements result from an advanced network topology, which supports both macro cells and a mixture of low-power nodes (femtocells, picocells and Relay Nodes). This gives users a far better service thanks to mixed network topologies, capable of combining big and small cells and of providing service to a larger number of simultaneously active users.

The standard’s other main goal is to enhance the service provided to users who are at the edge of a cell. This is achieved by providing simultaneous communication from the cell node the user is connected to and from the node belonging to the neighboring cell.  The main improvement linked to this was added to 3GPP Release 11 and is known as CoMP (Coordinated Multipoint Operation). It allows the user to communicate, in a coordinated fashion, with two base stations and achieve a spectral efficiency of 2.4bps/Hz/cell with a 2X2 MIMO configuration.

Given the content we find in today’s mobile applications, the upstream and downstream speeds may seem somewhat excessive. The goal, however, is not to give maximum speed to a single user, but to increase the speed for all and provide the best possible service to a growing number of users operating in each cell.

LTE advanced has succeeded in introducing mobile communication (for service provision) in many new sectors where it was previously unthinkable, whilst doing so in an effective and efficient manner. The mobility market (trains and automation) is an eloquent example.

In Teldat, we work using LTE Advanced technology and we cover every available band worldwide (both for LTE-FDD and LTE-TDD networks). Moreover, our devices are LTE Cat 6. This guarantees LTE Advanced operation, and allows two carriers to be added in two different bands (for a 40 MHz aggregated bandwidth) to double the LTE Release 9 bandwidth. We also use 2×2 and 4×2 MIMO technology, which improves performance in every environment and is compatible with LTE Release 11.
