Have you ever thought of using a wireless all the office? Do you think it is at this point not possible / it is not practical? If your answer to this question is yes, then you must read this book for you.
Let us first look at the reverse situation: What would the advantages of wired networks over wireless networks? Well, you could be the immediate points that I will be:
1. Speed. Wireless networks are asslow and low bandwidth.
2. Real-time applications. Wireless networks can not use real-time applications like voice and video.
3. Security. The wireless signals to reach, even on the road. What if someone hacks into my network?
4. Incompatibility: Certain devices such as printers, etc., are not Wi-Fi enabled. The PC does not have Wi-Fi cards.
Let's look individually at each point (I write this in the perspective of aCompany / office network and so I am assuming that the Wi-Fi network is set up with wireless controllers, access points and management software)
Speed:
Wired had a decent rate of 100 Mbit / s and these days have a speed of 1000 Mbit / s. Wireless networks have only a speed of 54 Mbps and that is shared among many users.
Give me an application that would take a 1000 Mbps per port, or even 100 Mbit / s per port, and then I probablycould accept the above statement. The fact is, even if your office is running demanding applications such as multimedia, ERP, video etc can, not the maximum bandwidth per user request to cross even 4 Mbps! Now take the 54 Mbit / s of Wi-Fi networks, and assume that there are 15 people to connect to, any user can get around 2.5 Mbps, which is sufficient for most applications that we now have, and if all 15 members do not connect at the same time, a single user has more bandwidth.In fact, with the advent of the 802.11n standard for Wi-Fi, the available bandwidth per access point 300 Mbit / s and 600 Mbit / s is to touch in the near future. So, even if 15 people connect to a 802.11n access point, they could now get in excess of 20 Mbps, which is more than sufficient for most applications on the network.
Real-time applications:
What if I run PC-based video conferences in my company? Can the wireless networks handle real-timeTraffic?
A decent video conferencing client no longer than 256 to 384 Kbps for the grant of 30 f / s video with H.264 compression. How many such conferences will happen simultaneously? And real-time applications run very well if your wireless controller can support WMM - Wireless Multimedia Protocol, which the real-time traffic prioritized over the normal traffic, and most of today support controller. Even voice is supported on the Wireless LAN - including the seamlessHandover from one AP to another when you wear the VoWLAN handsets. It is an interesting technology that is growing rapidly, the FMC is called - Fixed-mobile convergence, location of your IP phones and cell phones can be integrated with a single mobile phone and you have a number for both. Although IP-fixed) are not supported by wireless LAN networks, such as innovation (such as FMC and VoWLAN handsets for voice over wireless as well as additional features to help give the Primary care much more efficiently.
Security
The wireless signals penetrate the walls and in fact cross the street - what if someone hacks my network?
This is a legitimate concern. The security is at risk if your wireless communications are not encrypted with the latest standards and appropriate security policies are not applied. But if security policies are applied according to the latest standards (802.11i, etc), then the chances of breaking the> Network from the outside is very less. There is also wireless intrusion prevention software that are available on the market these days, the drops keep scanning for wireless threats and instruct them or even thwart attempts to automatically pass on your wireless network.
Incompatibility:
There are certain devices that are not yet compatible WLAN - how certain printers, fax machines, etc. But you'll be surprised how many devices have Wi-Ficompliant and have commercially available Wi-Fi-based products already - Surveillance cameras, multifunction devices, access control card readers, laptop computers, projectors, and almost any network-based device has a Wi-Fi-compliant model. Even if certain products are not Wi-Fi compatible, cable may be selectively taken alone, for such applications instead of wiring the entire office with three ports per cabin! In fact, home wireless access point to LAN cables are plugged into the backEnd so that a limited number of wired switch ports required anyway. And there are USB-based Wi-Fi adapter can be used to make a desktop computer (PC) wirelessly.
So after it is established that networks are wired not inherently superior to the current generation of wireless networks, let us now consider the additional benefits that wireless networks over wired networks:
Lower costs - not only save in the amount of cables, switch portsnecessary, but also in the cost of passive components.
Comfort and mobility - the wireless networks is available always and everywhere - even in the cafeteria and the lawn. All you need is a wireless-enabled laptop to access them. from anywhere - cars, etc., conference rooms, lawn network and users can connect to the
Redundancy: If an access point fails, change to another nearby access points to automatically connect the user (without the port connection manuallyas in wired networks).
Network Access Control, AD integration: The centralized management functionality of the wired networks with Active Directory (or LDAP, etc.) is today with most wireless networks. And in fact based wireless networks can also Controller and Network Access Control - Grouping of users deciding which users can access which resources on the network (restrict certain users access toon the Internet, etc).
Load balancing: The access points can automatically push the user to the neighboring access points if they are overloaded. Some controllers even allow to limit the network bandwidth that a single user / group access on the LAN, so that they do not overload.
There are many more like, but if you continue to discuss on the same or on a particular topic, hop on our blog. There is a whole category of wireless networks!
