With mobility and flexibility becoming increasingly important to your business and its employees, have you taken time to consider what sort of network best suits your needs? Should you continue to rely upon a wired network, or is it time to go wireless?
The WiFi vs ethernet discussion is one had more often than you might expect. Both wired and wireless networks come with pros and cons for your business, but understanding the differences will help you make the right decision. When it comes to determining which of these networks for business is better, the conversation has to start with you. I'm certain your workplace already has a network in place. Which one is it? Is it meeting your needs? What problems are you facing with it?
These are likely the most important questions to begin assessing your current network. In this blog, I'll be sharing the pros and cons of both options. Wired networks have remained a popular choice because they offer two obvious advantages: security and speed. Additionally, robust security measures are more easily put in place on a wired network, increasing its security. With advancements in security solutions, we can determine the who, what, where and when of a data breach on both wired and wireless networks, ensuring proper security is taken into account.
Wired networks come with two primary drawbacks: expense and clutter. As the name suggests, a wired network requires cabling or ethernet cords. These cords crisscross offices to establish a physical connection with every device needing network access.
Employees can resent the tangle of wires beneath their desk. It's usually not a functional issue, but troubleshooting becomes challenging when cabling is an issue. In most office environments, workstations and employees use wireless devices, so even with wired networks, employees elect to use wireless.
Wired networks are oftentimes more expensive to install than a wireless network. The cost of wired networks comes in the form of installation charges and cabling. Since each workstation and device in the office that needs a connection requires a wire running to it, the size of your office space affects the cost of a wired network.
For this reason, the flexibility and scalability of wireless networks appeal to businesses. With a wireless network, it is easy to provide employees with access, which they can use to connect multiple devices.
Tablets, smartphones and laptops can all connect to the network allowing employees to access work files on the go, without a physical connection. People can walk into any library, coffee shop, airport or mall in America and get Wi-Fi access for free.
Whether it is your employees or clients visiting the office, people expect Wi-Fi access. The same can be said for your office. There are some extra considerations to be addressed in securing a wireless network.
For example, many businesses don't have a secure screening process to sort through those who are and aren't authorized to connect to their wireless network. And the same can be said about authorized and unauthorized devices. Another concern with wireless networks is coverage. While some office buildings and certain locations can suffer from dark spots, the issue can typically be overcome with the right amount of attention to bandwidth, redundancy and routine upkeep.
It is recommended to place an access point for every square feet, depending on the material construction of the building. To provide a good wireless infrastructure, a solid wired infrastructure is a requirement, as this is the backbone for all wired access.
Wireless is just an access method; it still relies on the wired network for backhaul. The best option for most businesses is a combination of the two systems. A wireless network that is integrated into your wired network allows your employees to access the network remotely, while also providing guests with complimentary Internet access on your premises.
It also maintains the benefits of a wired network, such as robust transmission levels and a more reliable connection. These two factors can be particularly critical for businesses that rely upon heavy data transmission. A hybrid system will likely be the best solution for your organization. Not necessarily. While popular opinion might lead you to believe that connecting to a network via ethernet cable is safer than connecting via WiFi, it just isn't the case anymore.
In today's world, there are many additional factors that go into establishing a secure connection. Everything from how up-to-date your operating systems are and the quality of your organization's password policy to the physical and digital security of each individual device that connects to your network has an impact of network safety and security. Request a consultation with a Networking Specialist to get answers to your networking questions and determine what solution is right for your business.

Telecommunication is the transmission of signs, signals, messages, words, writings, images and sounds or information of any nature by wire , radio , optical or other electromagnetic systems. It is transmitted through a transmission medium , such as over physical media, for example, over electrical cable , or via electromagnetic radiation through space such as radio or light. Since the Latin term communicatio is considered the social process of information exchange, the term telecommunications is often used in its plural form because it involves many different technologies. Early means of communicating over a distance included visual signals, such as beacons , smoke signals , semaphore telegraphs , signal flags and optical heliographs.

A programmable logic controller PLC or programmable controller is an industrial digital computer which has been ruggedized and adapted for the control of manufacturing processes, such as assembly lines , or robotic devices, or any activity that requires high reliability control and ease of programming and process fault diagnosis. PLCs were first developed in the automobile manufacturing industry to provide flexible, ruggedized and easily programmable controllers to replace hard-wired relays, timers and sequencers. Since then, they have been widely adopted as high-reliability automation controllers suitable for harsh environments. A PLC is an example of a "hard" real-time system since output results must be produced in response to input conditions within a limited time, otherwise unintended operation will result. Programs to control machine operation are typically stored in battery-backed-up or non-volatile memory. Before the PLC, control, sequencing, and safety interlock logic for manufacturing automobiles was mainly composed of relays , cam timers , drum sequencers , and dedicated closed-loop controllers. Since these could number in the hundreds or even thousands, the process for updating such facilities for the yearly model change-over was very time consuming and expensive, as electricians needed to individually rewire the relays to change their operational characteristics.

Internet of Things IoT is a sprawling set of technologies and use cases that has no clear, single definition. One workable view frames IoT as the use of network-connected devices, embedded in the physical environment, to improve some existing process or to enable a new scenario not previously possible. These devices, or things , connect to the network to provide information they gather from the environment through sensors, or to allow other systems to reach out and act on the world through actuators. They could be connected versions of common objects you might already be familiar with, or new and purpose-built devices for functions not yet realized. They could be devices that you own personally and carry with you or keep in your home, or they could be embedded in factory equipment, or part of the fabric of the city you live in. Each of them is able to convert valuable information from the real world into digital data that provides increased visibility into how your users interact with your products, services, or applications. The specific use cases and opportunities across different industries are numerous, and in many ways the world of IoT is just getting started. What emerges from these scenarios is a set of common challenges and patterns.

The most important promise made by the proprietors of 5G wireless technology -- the telecommunications service providers, the transmission equipment makers, the antenna manufacturers, and even the server manufacturers -- is this: Once all of 5G's components are fully deployed and operational, you will not need any kind of wire or cable to deliver communications or even entertainment service to your mobile device, to any of your fixed devices HDTV, security system, smart appliances , or to your automobile. If everything works, 5G would be the optimum solution to the classic "last mile" problem: Delivering complete digital connectivity from the tip of the carrier network to the customer, without drilling another hole through the wall. Also: Should 5G be in your IT budget? The "if" in that previous sentence remains colossal. The whole point of "Gs" in wireless standards, originally, was to emphasize the ease of transition between one wireless system of delivery and a newer one -- or at least make that transition seem reasonably pain-free. Not that any transition has ever been a trip to the fair.
