NFC – Near Field Communication & Its Applications
NFC, also called as Near Field Communication is a short range wireless communication network that can be used by two devices supporting the NFC Standard to communicate with each other over a short range (20 cm, practically around 4 cm). NFC can be integrated into smart phones, tablet computers, laptops/ computers, point of sale... »
IEEE 802.11ac & IEEE 802.11ad Wireless Technologies – Think beyond 802.11n!
Earlier, Wireless Networks were slow to catch up with Wired Networks in terms of speed and bandwidth. But with the implementation of IEEE 802.11n Wireless Networks, the equation slightly balanced out. Now, two more Wireless protocols (IEEE 802.11ac & IEEE 802.11ad) are in the making and they supposedly bring gigabit ethernet performance over the... »
An introduction to Zigbee / IEEE 802.15.4 Wireless Network
Zigbee or 802.15.4 is a wireless network standard to create a wireless network using low cost, low power consumption & low data rate connectivity devices. It can beat your Wi-Fi networks hands down for certain applications like industrial automation, medical patient monitoring, etc due to its prominent features. Let us find out what they... »
How secure is your Wireless Access Point?
Wireless networks are very comfortable and easy to use. Hence, a lot of people set up Wi-Fi connections using a wireless router or wireless access points. Even a small business/ SOHO normally has a standard access point to provide wireless network access to its employees. But, how secure is this Wi-Fi connection? Can it... »
WiFi Adhoc Networks – What they are & how to mitigate the threats posed by them
An ad-hoc network is enabled by connecting a wi-fi enabled device directly with another wi-fi enabled device over the wireless medium without requiring a wireless router / access point. But how secure is this mode of connection? What can you do to mitigate the threats posed by ad-hoc networks in an enterprise? Let us... »
Can a Wireless Network eliminate a Wired Network completely?
Implementing a wireless network does not mean that a wired network can be completely eliminated - At best, it can reduce the edge switches/ switch ports and cables/ passive components. In this post, let us try to understand what components are reduced and what components are added to a network, when a wireless... »
An overview of bluetooth technology and its enterprise applications
Bluetooth is a low power, short wave, short range wireless technology that is used to transfer data between two devices over the wireless medium. In this article, we will have a look at a short overview of bluetooth technology and its applications in enterprise companies. »
Why Wireless Interference is an important consideration in Wi-Fi networks
Unlike a Wired Network, where adding more network switches gives better performance, a wireless network cannot be optimized for performance by adding more access points/ denser deployment of access points - mainly due to the Wireless Interference. In this article, we'll try to understand frequency bands, interference, interference from 802.11 Wi-Fi enabled devices, interference... »
Why a Site Survey is crucial before implementing a Wi-Fi network
Planning for a Wireless network is not as simple as Wired network. Unlike wired networks, over-provisioning (of access points) is not a very good idea with wireless networks because of the increased possibility of co-channel interference with many access points. That's why wi-fi site surveys are crucial, and in this article let us understand... »
Honeypot & Man In the Middle (MITM) Attacks on Wireless Networks
What is a Wireless Honeypot Attack? Normally, when a wireless client (PC, Laptop) is switched on, it will try to probe the nearby area for access points for a particular SSID (SSID is like a name for the network, which is advertised in order for users and clients to associate with the access points).... »
