At least. We’ll analyze 7 key factors you need to consider, including access points, bandwidth, network management, and the next 802.11ac standard.
The mobile trend has come to stay and this means that the number of smartphones and tablets is making its use in corporate networks rise. An increasing number of these devices are just Wi-Fi and this inevitably puts a strain on existing Wi-Fi networks. Companies that are (very) late or thinking about revising their infrastructure, this article was made for you and here are several important points to consider.
There is a large disparity between the cost of consumer access points (AP) with business-centric models of leading brands such as Cisco enterprise router, Ubiquiti, Intelbras, Ruckus. Taking this into account, the company often looks at costs and ends up opting for modems and home routers (enterprise router vs home router), which greatly hinders access to the internet and prevents your company and employees from having decent internet and Wi-Fi.
In fact, even consumer-grade models of high-end routers and modems can overload with only a few dozen simultaneous connections. Finally, noncommercial modems and routers generally do not have advanced capabilities in critical areas such as security, management, load management, remote deployment, and upgrade.
On the other hand, enterprise routers and switches are designed for solid performance 24/7 and dozens of Wi-Fi devices simultaneously. This is a stark contrast to the handful of intermittently accessed Wi-Fi devices typical of a home environment.
Currently there are two main frequency bands for 802.11 Wi-Fi networks: 2.4GHz and 5GHz. The greater amount of available bandwidth in the 5 GHz band makes it the preferred choice in business environments, although Wi-Fi clients operating in the 2.4 GHz frequency block have a better bandwidth. Most Business Access Points can operate in both frequency bands, while high-end models can serve Wi-Fi clients in both bands simultaneously. The shorter range of 5GHz allows Access Points to be deployed in closer proximity without overlapping signals and interfering with each other. This, in turn, allows a greater number of them to be deployed.
Note that most Wi-Fi clients still do not work in the 5GHz band. While the iPad 3 and the new iPad will work on a 5GHz network, low-end tablets such as Amazon Fire and Google Pixel will only connect to the 2.4GHz band. Likewise, most smartphones are only 2.4GHz.
In recognition of unequal support for 5GHz, some access points can be configured to backhaul data over the 5GHz frequency band, serving wireless clients in the 2.4 GHz band. This is particularly useful for enhancing reception without wire in places that wired cabling cannot easily reach. In addition, it is possible to set up a hybrid environment where both 2.4 GHz and 5 GHz radios are simultaneously in use. Devices supporting 5GHz can be directed to connect in this frequency band to reduce congestion in the fuller 2.4 GHz band.
As described in the previous section, increasing the number of access points could increase the amount of interference being generated, reducing overall responsiveness and speed on the internet. In fact, a large number of randomly deployed access points can reduce the number of devices that a wireless network can support. However, with each worker carrying up to three devices with Wi-Fi (for example, a laptop, a tablet, and a smartphone), IT departments should expect the number of such devices to increase, if not double, with Iot"s, wearables, and similar.
Therefore, careful placement and configuration is required to deploy a high density of access points to properly support a large number of wireless clients. Eunerd specializes in serving small and medium-sized IT infrastructure projects, providing ongoing support as businesses grow and their internet demand grows over time. If you are having difficulties with internet and IT in your company, Eunerd is the right company to call.
Managing and securing Wi-Fi networks is another aspect that businesses need to consider. Attempting to configure multiple access points individually in a business environment is not only highly inefficient, it is also prone to errors.
As you can imagine, a well-designed management system plays an important role in dealing with more than a handful of access points. In addition, the evolution of the security scenario has increased the importance of the built-in security features. Wi-Fi providers now incorporate security features that, among other things, identify unauthorized networks, defend against spoofing, or block brute-force attacks. In addition, the ability to log important system or security events on a syslog server or console is invaluable, making it possible to identify bottlenecks in wireless networks and security threats.
Another capability that is important for businesses to take is the (SSIDs). An SSID is the name of the network that users see when they connect to a wireless network. Although there are several types of SSIDs, this does not increase the actual capacity of an access point. However, this feature offers a number of important advantages in front of security and management.
You can configure different levels of security for each SSID. A network for guest users can be designated as an open network, while wireless network cameras can be connected to a network protected by a long static Wi-Fi Protected Access 2 (WPA2) key, while another network can be configured to authenticate via RADIUS and used to serve employee laptops. Depending on the SSID, clients can be routed through different virtual LANs to segregate traffic.
A less obvious problem with setting up multiple wireless access points is the possibility of having to deploy them in inconvenient locations for maximum coverage. Feeding these access points using Power over Ethernet (PoE) simplifies the problem, while saving companies the cost of putting separate power cable runs for each access point. PoE"s provide power over the same Ethernet cables that power the data to the access points, offering speeds up to 1 Gbps, which is more than the right performance for the fastest commercially available access points.
Companies that do not yet have an on-site PoE infrastructure can easily deploy "PoE midspan" injectors into the server room or closet. Alternatively, PoE-compatible network switches are relatively affordable now and it"s a good choice while keeping server cabinet equipment down counting is a priority. The power supply of access points via PoE also helps in the maintenance front; IT departments can more easily replace standard PoE injectors and switches that fail compared to the need to compete for a specific AC adapter. In the same vein, it is much easier to troubleshoot a single cable than to check the data link and power adapters separately.
Finally, PoE allows the use of standard UPS equipment to power PoE switches or injectors to protect APs against power outages. Obviously, a PoE strategy requires the use of access points with inherent PoE support, a feature typically found only at corporate access points.
The need to manage and coordinate multiple access points requires that you use a central controller for anything other than the smaller implementations. Because vendors have built their Wi-Fi solutions around one or two different architectures, the controller architecture is less influential in purchasing than factors such as manageability and interoperability. However, this should not prevent companies from properly understanding the strengths and limitations of each option.
The most common project involves the use of a central appliance to configure and manage multiple access points on the network. There are also vendors that incorporate controller logic into existing network devices such as Peplink"s WAN load balancers that can be used to manage the access points sold by the company. Wi-Fi Xirrus uses a "thin" access point strategy in which each array independently manages all the integrated access points.
Finally, there are cloud-based controllers managed entirely by the Internet, such as those made by Meraki. In an attempt to reap the benefits of a centralized console without having to invest in a controller-based solution, Tanaza has created a cloud-based management solution in which access points that are not in the default cloud are configured online and the changes are automatic. Good architecture options that should be taken into account.
With the 802.11ac wireless standard already near here, the ability to upgrade to what is broadly termed as "Gigabit Wi-Fi" would obviously be a compelling feature for many businesses.
It is important to remember, however, that it is still in development at this time and is not expected to be completed until next year. In fact, the APs currently being shipped with 802.11ac are essentially uncertified, and client devices that implement 802.11ac are likely to arrive only a few months after the 5GHz standard is rectified.
For these reasons, companies wishing to deploy Wi-Fi today should just move on with their current plans rather than hold on and wait for technology that is at least a year away.
In the New Year, how about taking one of the best free cybersecurity courses online and get yourself a new qualification?
These brilliant courses prove that it doesn"t need to be expensive to become qualified in cybersecurity. While you will ideally need to take a degree or other accredited course in computer science, in which you can choose networking and security topics to suit your career path, there are other options available that you can try in order to test the waters and see whether the industry really is for you.
Find out the average salary of Cyber Security Consultants?
One of the best ways to do this is by signing up for a free online taster course, which introduce some of the basics. These are a great way of seeing if this is the sort of career you"d like – but if you want to become an industry professional, then you"ll need to sign up for more advanced courses.
Even still, some of the free providers do also provide paid courses which are often cheaper than undergraduate study, and may allow not just for suitable training but also industry connections to help on your path.
Therefore if you really are interested in exploring cybersecurity, try some of these featured courses to get an idea of whether you might suit the industry, and vice versa, but do be aware that any free training will generally be quite limited.
Compiling data drawn from surveys sent out to more than a thousand IT and IT security practitioners within the UK and US, the Ponemon Institute, in collaboration with DomainTools, have recently published their insights in the report titled “Staffing the IT Security Function in the Age of Automation”.
Will automation shrink IT security functions’ headcount?
According to the report, more than half of the respondents (51%) believe that automation will lead to a loss of employment opportunities within the security field. This mentality seems to have shifted quite dramatically as it has risen by 30% in comparison to the results obtained last year. Between the UK and the US, however, it would appear that this rising belief is especially pronounced among the UK respondents, with 56% answering that it would reduce headcount, compared to 45% of US respondents. Correlating with this belief, is the upsurge of concern that they may be made redundant due to automation, from 28% to 37% in the last year alone. Yet, despite these fears, around 1 in 7 organisations’ IT security functions are understaffed.
Humans won’t become obsolete
While most respondents agree that automation has the benefit of freeing IT security staff from the more mundane tasks to focus on resolving serious vulnerabilities, there is still an underlying understanding that the role of humans is indispensable. Indeed, only 40% of respondents trust automation to reduce human error and 74% insist that automation is not capable of accomplishing certain tasks done by IT security staff. In this way, it looks as if the sentiment towards automation is bittersweet.
Nevertheless, rather than the loss of bodies within the sector, Dr. Larry Ponemon, chairman and founder of the Ponemon Institute, responds with optimism. He states that “What is more likely is for there to be a consolidation of existing roles, rather than an elimination. This means better opportunities for employees to up-level their current skills to create more value-added roles as the human side of security remains as important as ever.”
Another standard system problem - again, with Windows operating systems - is a DLL error. This means that a DLL file is missing or corrupt. Files that end in ".DLL" are dynamic link library files.
They holded many codes and instructions for programs. They exist to tell the operating system how to handle certain applications. Several programs can also open them simultaneously, which improves memory conversion.
A DLL file is essentially a unique feature that developers can include in their applications. These files contain instructions for the computer and the operating system (operating system). If one of these files is missing, it can cause a lot of problems, especially since there are many.
What does a PC Repair Technician do?
The best way to manage missing DLL files is to use the System File Checker, an integrated Windows utility. It will scan the system files on your computer"s main hard drive and make sure something is missing or corrupted. It is quite possible that files exist, but they may become corrupt over time. This can even happen if a hard drive starts to fail.
The System File Checker will scan all the necessary directories and replace or repair the files if necessary.
You can also use your Windows installation CD or installation ISO to manually copy the necessary DLL files, but this is much more complicated.
Financial terms of the deal have not been publicly disclosed. As part of the acquisition, Arista is bringing in approximately 75 Big Switch employees, most of whom are from the company"s engineering division. Big Switch was founded in 2010 by by Guido Appenzeller and Kyle Forster and had raised approximately $119.5 million in venture funding.
In a 2012 video interview with EnterpriseNetworkingPlanet Forster explained the genesis of the company and its mission, which at the time revolved around the open source OpenFlow protocol for SDN. The company expanded its focus and offerings over the years and now has two core offerings with the Big Monitoring Fabric and Big Cloud Fabric.
Big Switch has also grown thanks in no small part to its strategic partnerships, including one with Dell Technologies
Arista stand to benefit in a big way
Arista Networks CEO Jayshree Ullal took time during her company"s fourth quarter fiscal 2019 earnings call to provide some insight into why Big Switch was acquired. She noted that the acquisition is a strategic step for Arista in bringing a strong combination of engineering expertise, deeper entry into the network packet broker market and increased software multi-cloud visibility.
Who is a Switch Network Repairmen?
"We"ve always been focused on software-driven networking as a mission in Arista," Ullal said. "With Big Switch, we are expanding that mission to a more deep analytic strength complementing our switch based dense or data analyzer platforms with Big Switch"s deeper monitoring fabric across public, private and hybrid clouds."
From a product perspective Ullal noted that the Big Switch monitoring fabric is a complementary solution to Arita"s DANZ (Data ANalyZer) software. In her view, the Big Switch technology is the "icing on the cake" providing deeper visibility, service nodes, recorder nodes and monitoring fabric capabilities. The Big Cloud Fabric is also expected by Ullal to be an important product, especially with Arista"s converged infrastructure partners like Dell Technologies.
Beyond just new products and capabilities, Big Switch also brings new customers to Arista. According to Ullal, Big Switch had approximately 300 customers.
A Linux-administrator wears a lot of hats, and the smaller your environment, the more hats you have. Linux management includes backups, file recovery, disaster recovery, new system releases, hardware maintenance, automation, user maintenance, home file-systems, application configuration and conformation, system security and storage management. System management is involved in almost every aspect of managing the hardware and software of physical and virtual systems.Strangely, you also need a large knowledge base of network settings, virtualization, interoperability, and even Windows operating systems. The Linux system-administrator must have technical knowledge of all aspects of network security, firewalls, databases, and the work network.
However, the reason is that, above all, Linux-Admin, you are part of a larger support team that often has to work together to solve complex problems. Security, in one form or another, is at the heart of the problems that the support team faces. The user may not have the correct access or approach too much. Daemons may not have the correct permissions to write the log file. No firewall exceptions were saved while performing the network configuration. There are hundreds of failures online, and it is your job to help you find and correct them.Linux management also needs to follow best practices, learn new software, maintain patches, read and follow security announcements, and apply hardware updates. On the other hand, Linux certification pathand training day is very full of perks. In fact, it never ends, but you have to choose the time to stop the commercialism.
Users can now create and track multiple performance metrics from a single SLA. Custom metrics can now be added to SLAs, allowing for additional performance measurements. Create custom metrics using filters, and control precisely what ticket states should count against individual SLA metrics.
A few examples:
SLA based services are services that are based on a service level agreement (SLA). This is a contract between a service provider and the end user that sets out the level of service that the service provider is expected to offer. They define what the customer is going to receive in exchange for their money, although not how the service will be delivered.
Help Desks are a subset of Service Desks – however, there are subtle differences of focus with the two. Service Desks aim to manage higher level, strategic IT processes and is also referred to as Managed IT services or similar, whereas IT Help Desks are usually found in a separate service on its own dedicated to serve specific common issues for end users.
Help Desks refer to providing solutions to issues usually experienced by end users which can differ according to your business. This is usually done through a ticketing system involving the end-user being guided through problem shooting methods and solutions via the Help Desk on their various issues. Some examples of Help Desk services would be responding to calls and customer requests as quickly as possible and recorded through an online ticketing system.
On the other hand, Service Desks are referred to strategic level processes and are the main point of contact for companies aligning the technology used in the business with the company’s goals and processes.
IT Service Desks (included in our Managed IT Services) aims to ensure the overall IT processes and infrastructure are working at its best to serve the company or business goals it’s been created to achieve. IT Service Desks encompass processes such as improving asset management, enhancing operations, allowing better communication between business departments and more.
Customer experience initiatives will be integrated into the broader digital strategy according to a report on CX by Ecosystm. IT teams and frontline departments have to work together to impact how customers interact with the business, which means innovation and collaborations are crucial.
Customers are judging the value delivered by a company based on solely their personal experience.
They want exceptional experiences both online and offline, and their expectations have never been higher thanks to the normalising of on-demand services.
This places additional IT pressure on top of the regular business operations, in order to keep up with the evolving needs of consumers.
On the backend, employees are relying on various platforms, applications and data to drive new user experience (UX). Greater demand in these business functions brings to light the importance of the network.

The use of Multi-Protocol Label Switching (MPLS) in the past has served the basic IT needs.
With the entrance of cloud services, the wide area network (WAN) is becoming a complicated place.
An enterprise HQ is no longer just connected to a few offices and data centres but a number of on-ramps from branch locations to the cloud. MPLS is deemed too slow and expensive to support this hybrid cloud environment.
Over the last few years, software-defined wide-area networking (SD-WAN) emerged as the ideal replacement for MPLS.
This was the starting point for network transformation in enabling businesses to leverage new levels of performance, agility and intelligence when connecting their applications and services for end users globally.

the latest smart out-of-band management tools offer a positive way forward. Not only can they provide an alternative path to devic¬es located at remote sites when the primary network is down, helping mitigate the risk that SD-WAN can bring, they can also help facilitate access to edge infrastructure to ensure business continuity. Moreover, using a separate management plane solution allows organisations to securely monitor and access all devices without impacting normal operations.
In addition to providing access when an issue arises, SD-WAN also enables organisations to improve day to day operations. Proactive monitoring enables staff to pre-emptively recognise and remediate issues to reduce the need for truck rolls.
Designed to provide the needed resilience at the edge, Smart Out-of-Band by Opengear is scalable, providing the ability to manage infrastructure at distributed sites. Troubleshooting and remediation at the network’s edge enables organisations to detect faults before they become failures which minimises downtime and operating costs.
This resilient backup connectivity allows enterprises to reduce the time-consuming nature of dispatching engineers to data centre sites to make configuration changes and trouble-shoot issues for business continuity. Smart Out-of-Band and Failover to Cellular™ ensures that SD-WAN continues to operate when all other circuits are unavailable, providing the always-on access needed at the edge.”
Like most SD-WAN-based solutions, Cato’s platform works at the edge of the network, where the LAN connects to the public internet, to access cloud or other services. As with other SD-WAN offerings, the edge must connect to something beyond the four walls of the private network. In Cato’s case, the company has created a global, geographically distributed private backbone, which is connected via multiple network providers. In essence, Cato has built a private cloud that can be reached over the public internet.
That global private backbone incorporates the elements of SASE and brings forth fully converged networking and security to each edge connection. Cato makes that possible with the Cato Socket, Cato’s SD-WAN device. The Socket is a physical appliance (or virtual one for the cloud) that routes all traffic from the edge to the closest cato PoP (Point of Presence). There are more than 50 cato PoPs, and those POPs share the data-center footprint of the major cloud providers, meaning that not only is there a Cato POP close to all major business centers worldwide, but that latency from Cato to your cloud provider is likely to be nominal at most. Cato’s global routing optimization significantly reduces latency when compared with the public Internet. Throughput is also improved by the WAN optimization built-into the Cato software.
With the core security and networking processing occurring in the Cato Cloud, the Cato Socket brings enough networking capabilities to overcome last-mile issues and bring the traffic into the nearest Cato PoP. The device implements QoS prioritization, which can be driven by applications, users and other definable elements. The Socket also institutes other traffic management capabilities, such as dynamic path selection and the ability to connect to a mix of fiber, cable, XDSL, 4G/LTE and MPLS connections.
The HP Color LaserJet Pro M254dw is our pick for the best laser printer because it’s easy to use, produces brilliant results, and enjoys laser printing technology’s superior reliability. No matter how long you leave it sitting unused, you can turn it on and it’ll start printing more or less right away – and without wasting any toner on cleaning cycles.
Though it’s more expensive than a comparable monochrome laser printer, it’s also far more flexible. In addition to crisp text, it produces vivid colour graphics and can even turn out respectable photos (just not on photo paper). Print speeds are quick, and per-page costs are reasonable. This model’s smartphone-style colour touchscreen makes changing settings simple, and HP’s PC and mobile software is the best in the business.
Unlike most other printers, the M254dw can connect to 5 GHz wireless, which should speed up big print jobs and helps ensure that the printer won’t lose connection over time.

The M254dw can take a minute or two to get going for very large print jobs. We saw this issue only once during testing, but several owners have reported it in reviews. Because this printer comes with a skimpy set of “starter” toner that’s good for only 800 black-and-white and 700 colour pages, you’ll probably need to buy replacements within a year or so of purchase.
Getting cartridges with the highest possible capacity makes the best financial sense. Thanks to all that toner, this printer is big (long, in particular) and heavy; make sure you have a space that can accommodate it. And, of course, the M254dw is just a printer – it doesn’t include copy, scan, or fax capability.
The industry is about to reach an inflection, because there is little to be gained from new manufacturing technologies anymore, except for a few rich companies and applications. For most of the industry, the free ride is over, and they will have to find new ways to get more from the same.
We are seeing potential opportunities everywhere. GPUs successfully managed to force a programming paradigm shift because without it, it was impossible to get anywhere close to optimal performance from the hardware. We are seeing similar things happening with AI across the board – even system companies coming in and designing their own devices because they can find nothing on the market that comes close to satisfying their needs. They are also creating new languages, programming paradigms and tool chains to support them.

We are seeing opportunities within all segments of the market for processing near memory. This ranges from small IoT devices to data centers. It is not difficult to make these devices and demonstrate how much better they are, but they come at the cost of requiring software changes.
We are seeing open source hardware looking like a viable option for the first time, but the industry is perhaps not quite ready with the necessary ecosystem and tooling. In many cases, no tools exist because the market for, let’s say, processor verification tools, was so small that it was unviable to produce tools for them. It will take time for the industry to catch up.
We are seeing systems where memory performance and interfaces are getting in the way of progress, because a single contiguous, coherent memory system is easier to program, requiring no thought from the software.
