Which LPWA technology?

Which LPWA technology?

To support the expected communication needs of the Internet of Things, IoT, with more than three billion connections by the end of 2020 as predicted by Strategy Analytics, several low power wide area, LPWA, radio technologies are been developed and pushed to the market by the communications industry. The use cases or applications that the IoT will make possible are being widely discussed:...

SD-WAN and security implications –Part 2

SD-WAN and security implications –Part 2

  In my last blog, I wrote about the origins of SD-WAN and its benefits. However, these advantages are certainly not without their challengers and threats, which all interested companies should consider when analyzing the various options offered by the market. From a security point of view, the main threats arising have to do with the use of unprotected residential broadband networks....

SD-WAN and security implications – Part 1

I have written an article on SD-WAN for Seguritecnia, an online and print magazine that is very present in the private security sector in Spain. In said article, I explained the concept of SD-WAN and the security implications associated to this technology (as befits a magazine that focuses on safety). Given the enormous interest in SD-WAN, I decided to give our blog readers the opportunity of...

Application visualization and control needs

Application visualization and control needs

Why has visualization of applications over network become such a critical point? Firstly, the move of IT infrastructure to the cloud means our current understanding of level 3 network traffic (IP) is insufficient to characterize applications transmitting over said network: Application servers had fixed, known IP addresses in traditional data centers, whereas IP addressing in cloud is no longer...

Dismantling the ISDN and POTS networks

Dismantling the ISDN and POTS networks

How can we help carriers dismantle their ISDN networks easily, economically and above all, transparently? Traditional ISDN and POTS communication networks are now obsolete.  Deployments using old technology, the devices making up these networks, etc., have reached, in many cases, the end of their lives.  Another influencing factor is that experts and technicians in this field are approaching, or...

Beyond Gigabit Ethernet on the LAN

The coming generation of enterprise Wi-Fi Access Points will allow higher than 1 Gbps sustained payload data rates between the radio interface and the wired network to which they are connected. For this reason, current LAN infrastructure, that is mostly Gigabit Ethernet over CAT5e cabling, will become the bottleneck on the LAN communications. The alternatives to overcome this bottleneck are...

ONT SFP GPON: End-customer solution

ONT SFP GPON: End-customer solution

With the deployment of fiber to the home (FTTH), telecommunications operators put their main focus on the residential market. This is logical, since it is where there is volume and where a small increase or decrease in revenue per subscriber is converted into outstanding results on their financial accounts. As with almost any other access technology, once the number of households with the...

What is a wireless LAN controller and who has taken it to the cloud?

The main function of a traditional wireless LAN controller (WLC ) is to configure wireless access points (AP) that connect to it locally. However, due to the technological characteristics of a wireless area network (or Wi-Fi as it is commonly known), the traditionally used Wi-Fi network architecture and the manufacturers’ commercial strategies, a WLC carries out or can carry out many other...

LTE, new Connectivity Scenarios for businesses

LTE, new Connectivity Scenarios for businesses

In 2000 the GPRS technology was introduced. It offered the true possibility of transmitting data through 2G cellular networks, by adapting a circuit-switched network, designed to transmit voice, to a packet-based network. Almost a decade and a half ago, the common speed you were able to reach was 40 kbps on the downstream (from the network to the mobile terminal) and 14 kbps on the upstream...
