What is a Wireless Local Area Network (WLAN)?

October 17, 2022

What is WLAN WLAN stands for Wireless LAN network. Two devices can communicate wirelessly by using the WLAN technology. In WLAN there is no cable required between the devices. The devices can communicate by using Wi-Fi and transmit all the data over the Wi-Fi. It’s totally different from the traditional LAN network. Both LAN and Wlan perform the same function but the Lan cable is required between the two devices in order to transmit the data and the WLAN performs the same function without using a cable. It transmits all the data over Wi-Fi. All the new devices come with Wlan technology. All the new devices use the DHCP technology in order to connect the new devices with the main device. Difference between WLANs and Access Points A WLAN (Wireless Local Area Network) allows two or more devices can connect and communicate wirelessly to establish a WLAN within a specific

The difference between LoRaWAN and Sigfox

October 9, 2022

IoT applications are diversifying in the scale of implementation. Now IoT devices are not connecting to a router in the house to send temperature data but can monitor the soil health of an entire farm. Such scalability is due to the addition of trending LPWAN technologies. LoRa and Sigfox are the frontrunners among non-cellular LPWAN IoT technologies, and here we are comparing them. What is Sigfox? We have introduced what is sigfox in details before, Sigfox is a proprietary LPWAN technology that operates on UNB (Ultra Narrow Band). It operates through one partner per country and on different frequency bands complying with each country, including 868MHz in Europe and 902MHz in the USA. While Sigfox claims to have the highest range of LPWAN (10 to 40 KM), the data rate and bandwidth are quite limited. A Sigfox device can send up to 140 messages a day at 300 bits/s. the

What is mesh network and how it works?

October 8, 2022

What is Mesh Network Mesh network is the new technology in the field of wireless. The main purpose of the mesh network is to transmit the signal of Wi-Fi/internet in every corner of the house. Mesh network creates multiple routes between the connected nodes in order to transmit the information. The data transmit rate in the mesh network is very high compared to a simple network. As the mesh network has too many routes so there is no hurdle in data transmission. So the data is transmitted in the mesh network at a high rate. The mesh-based network topology is mostly used in big organizations and offices and somehow it’s also used in the offices. If any of one node is down in the mesh network the data is transmitted through another node. Multiple routers and switches are used in the large mesh network and these switches and the router

2.4GHz Vs. 5GHz Wi-Fi: What’s the difference and which is better

September 28, 2022

Wireless router uses different frequencies range in order to transmit the data over different devices like computer, laptop, smartphone, etc. Wi-Fi performs better as the frequency value is high. With higher frequency, the data travel at higher rates but covers a small area. The router that operates on 2.4GHz provides more range means to cover a large area but transmit the data at lower rates and the router which operates on 5GHz transmits data at higher rates but covers a smaller area as compared to the router which operates on the 2.4GHz frequency. Wi-Fi router is built to deliver a specific range of frequencies, so it’s important to think about which Wi-Fi band and the channel would best meet your demands and provide the best performance to the user.

What is a wireless bridge and how does it work?

September 3, 2022

A wireless bridge is a device that connects the two access points or the LAN segments by using infrared or microwave transmission. It connects the two different wireless networks that are separated by distance. In a wireless bridge one endpoint act as a master and the other end act as a slave. In a wireless bridge, the master node determines the frequency of the client side and the link established. A wireless bridge is only directional between points A and B, as opposed to an access point, which provides service to numerous endpoints or devices in a spread of 30 to 360 degrees. They are suitable for many different connectivity options because they may be used across small (a few meters) and long (miles) distances. Most of the wireless bridges are directional but some wireless bridges also transmit the signal in 360 degrees. Wireless bridges are mostly used where the
