Streaming live video is a data-intensive process. It requires a fast, stable internet connection to deliver the stream with a minimum of disruption and buffering. For today’s blog, we will look at the virtue of Ethernet hardwire connections versus WiFi.

Both of these options have a number of pluses and minuses when it comes to everyday internet use, but when you’re trying to stream live video, the situation is a bit different. Let’s look at a few of the major issues involved: speed, latency, reliability, and ease of use. Then we’ll talk about which option is best for live streaming.

Speed: Ethernet vs. Wi-Fi

When it comes to pure bandwidth, Ethernet cables are just plain faster than Wi-Fi. The fastest Wi-Fi technology currently available — 802.11ac — can reach peak speeds of about 3,200 Mbps.

This is actually faster than the connection speed of common Cat-5e Ethernet cables. However, the speed of 802.11ac is a maximum theoretical speed; you’re not likely to actually get internet that fast in practice. In real-world tests, 802.11ac networks top out at about 1,600 Mbps.

In addition, wireless networks divide their bandwidth between all the devices using the network. So, while a 1,600 Mbps connection may be speedy with a single device connected to the network, things change when more devices start to join. By the time ten or more devices are using the same connection, the speeds will be drastically lower.

Ethernet, on the other hand, has a theoretical maximum speed of 10 Gbps, or 10,000 Mbps, for each device. And unlike Wi-Fi, those speeds don’t degrade as more devices join the network. (That is, at least as long as the internet connection and networking infrastructure itself can handle the added traffic).

You can test the speed of your current connection at www.testmy.net.

The Situation Matters

During everyday use at home, these differences may not matter. For example, many broadband home internet connections may top out at speeds of 100 Mbps. In a case like this, modern Wi-Fi may offer plenty of bandwidth, even when many devices are connected to the network.

However, as soon as we start talking about really fast internet speeds and big data applications, Ethernet starts looking more favorable. For example, at a business or public institution, where hundreds or even thousands of computers may connect to a network at the same time, Ethernet will offer faster speeds for internal network connections.

Wi-Fi speeds also depend on the devices that are utilizing the network. 802.11ac, for example, is a relatively new standard and isn’t supported on many devices. Anything made before about 2014 will not support it.

Luckily, Wi-Fi routers are backwards compatible and will use the maximum speed supported by a given device, but this may be substantially slower than the network could otherwise handle.

Latency: The Ethernet Trump Card

The quality of an internet connection isn’t purely about bandwidth. Latency is also a critical aspect. Latency refers to the amount of time it takes for data to travel between your computer and the network, then back to your computer.

In this process, data transmission is the slowest link. And as it turns out, Wi-Fi is simply slower than Ethernet when it comes to latency.

Again, latency may not matter much in everyday internet use scenarios. But for some applications, it’s a critical measure. For example, internet gamers need the absolute lowest possible latency to ensure that their quick reflexes actually make a difference in the game.

Latency is also critical to consider when it comes to live streaming. Lower latency delivers packets of video data to the server more rapidly, which can make a dramatic difference to the quality of a live stream for the user.

Wireless Network Interference

Another downside of Wi-Fi is the prospect of signal interference. Fundamentally, Wi-Fi is a radio connection, which means that it uses electromagnetic waves to transmit data through the air. Other radios (in the router) pick up this signal and send it to the internet.

However, this means that the signal is subject to disruption. For example, many cordless landline telephones operate on the same frequency as many Wi-Fi radios. Operating these devices in proximity to one another can cause slowdowns, increased latency, and even total outages at times.

Other problems can cause wireless network interference as well. For example, objects like walls and appliances can slow down or degrade signals. This can create slower areas and even “dead zones” where the Wi-Fi won’t work at all. Microwaves can affect Wi-Fi, and so can neighbors using the same frequencies. Even weather can effect the reliability of Wi-Fi.

Ethernet signals, on the other hand, are less susceptible to interference. They can experience signal problems, but these issues are generally much easier to diagnose and correct than they are with Wi-Fi.

Wi-Fi vs. Ethernet for Live Streaming

Live streaming requires good internet connections on both ends of the stream to deliver video that doesn’t skip, buffer, or fail. Both the content producer and the consumer must have enough bandwidth.

But live streams to viewers with low-bandwidth internet connections can be re-encoded on the fly to use lower amounts of bandwidth. On the broadcast side, on the other hand, any internet connection issues can cause unacceptable problems for every single viewer. These problems can even make your stream completely unwatchable.

When it comes to live streaming, Ethernet connections will always result in a faster, more reliable stream and a better experience for users. Therefore, we recommend that you make every effort to connect your live streaming devices via Ethernet if at all possible.

Of course, there are some situations where using Ethernet just can’t happen. Perhaps you don’t have physical access to the network (you are a guest), or perhaps your device simply doesn’t have an Ethernet port, like many modern smartphones and even some laptops. (Adapters are available for most devices to allow Ethernet connection).

If there’s no other option, live streaming over Wi-Fi can work. But it can provide a lower quality stream than would otherwise be possible. A hardwired connection will be faster and more stable.

What is VDI?

Posted in Blog by on Apr 26th, 2014

What is VDI? 

Virtual Desktop Infrastructure or VDI is software technology that separates the desktop environment and associated application software from the physical client device that is used to access it. In common language it is a desktop inside a virtual machine. VDI centralizes the desktops of end-users giving them flexibility to access their desktop from anywhere any time on any machine. In this mode, all the components of the desktop are virtualized, which allows for a highly flexible and much more secure desktop delivery model. In addition, this approach supports a more complete desktop disaster recovery strategy as all components are essentially saved in the data center and backed up through traditional redundant maintenance systems.

Why VDI?

  • Flexibility
  • Security
  • Mobility
  • Save Time & Money

How To Prevent Cryptolocker Malware From Spreading

Posted in Blog by on Mar 18th, 2014

Dear All,

[Definition Source: http://en.wikipedia.org]

CryptoLocker is a ransomware trojan which targets computers running Microsoft Windows[1] and first surfaced in September 2013. A CryptoLocker attack may come from various sources; one such is disguised as a legitimate email attachment. When activated, the malware encrypts certain types of files stored on local and mounted network drives using RSA public-key cryptography, with the private key stored only on the malware’s control servers. The malware then displays a message which offers to decrypt the data if a payment (through either Bitcoin or a pre-paid voucher) is made by a stated deadline, and threatens to delete the private key if the deadline passes. If the deadline is not met, the malware offers to decrypt data via an online service provided by the malware’s operators, for a significantly higher price in Bitcoin.

 

Steps To Prevent CryptoLocker Infecting Your Files [Solution Source: Patwa Kinarivala Electronics Ltd]

1) Protect your computer or any device with good end point security software

2) Backup all your files regularly

3) Protect/Encrypt your folder in which you regularly store files with a password so that if at all this malware infects your system it can’t enter your any encrypted folder and infect your files
