Should I use 2.4 GHz or 5 GHz WiFi? [3]
Your wireless router uses radio frequencies to transmit internet to your WiFi-connected devices like smartphones, laptops, tablets and more. The difference between 2.4 GHz and 5 GHz WiFi comes down to speed and range
Your choice of 2.4 GHz or 5 GHz will depend on where and how you use your WiFi connection most.. A lot of electronic devices and appliances use the 2.4 GHz frequency, including microwaves, baby monitors, security cameras, and garage door openers
5 GHz will give you more signal strength and faster speed over a shorter range, compared to 2.4 GHz.. If you’re able to use most of your devices near your router, 5 GHz is your best choice to take advantage of higher speeds
The Different Types of Wireless Communication [4]
Did you know that there are almost 5000 satellites orbiting the earth right now? We have become used to instant communications and entertainment wherever we may live on the planet. However, it takes complex technology to maintain remote wireless communication and control of these satellites.
If you have a business, you may wonder how you can make the best use of the various types of wireless communication. Learn the answer by reading our in-depth guide to wireless technologies.
By means of satellites, people all over the earth can communicate with each other.. It may not be possible to send a signal to another country because, well, the curvature of the earth is in the way

Improving Spatial Reuse of Wireless LAN Uplink Using BSS Color and Proximity Information [6]
Improving Spatial Reuse of Wireless LAN Uplink Using BSS Color and Proximity Information. – We show that the BSS color can be used to predict the location of other APs, which can be used to estimate the interference received by the other AP when the node transmits a packet
This proximity information together with the BSS color can be used to determine whether a node receiving the preamble can start a parallel transmission or not.. – We propose a new method called PSC-UL that uses the BSS color and proximity information to dynamically control carrier sense threshold of the STAs
– We conduct extensive simulations to evaluate performance of the proposed method under various environments and parameters, comparing with other existing methods such as OBSS/PD, PSR and Dual-CST [5].. – : received power of the signal from node A to AP1.

Abstract – The proposed concept tries to avoid the use of RTS/CTS and maintain the same rate of successful frame delivery. So here implements a method in which a special sequence allots specific time intervals to each node for data transfer
CA? Definition from SearchNetworking [8]
CSMA/CA (Carrier Sense Multiple Access/Collision Avoidance). What is carrier sense multiple access/collision avoidance (CSMA/CA)?
It was developed to minimize the potential of a collision occurring when two or more stations send their signals over a data link layer.. In this scenario, CSMA requires each station to first check the state of the medium before initiating a transmission
For example, as soon as a node receives a packet to transmit across the network, it will check to ensure the channel is clear and no other node is transmitting at the same time. If the network channel is idle, the packet is sent.
Collision Avoidance in wireless networks [9]
We take a close look at so-called WiFi which is also known as IEEE standard 802.11. Consider the situation depicted in the figure, where each of the four nodes is able to send and receive signals that reach just the nodes to its immediate left and right
(A and D’s reach is not shown in the figure.) Suppose both A and C want to communicate with B and so they each send it a frame. A and C are unaware of each other since their signals do not carry that far
A and C are said to be hidden nodes with respect to each other. According to Wikipedia, the hidden node problem can be defined as “In wireless networking, the hidden node problem or hidden terminal problem occurs when a node is visible to a wireless access point (AP), but not to other nodes communicating with that AP.”
IEEE 802.11-2020: Collision Avoidance in Wireless Networks [10]
IEEE 802.11-2020: Wireless LAN Medium Access Control (MAC) And Physical Layer (PHY) Specifications has become the dominant solution for Wireless Local Area Networks (WLANs) due to its high performance, low cost, and easiness in deployment. IEEE 802.11 is used in most home and office networks to allow computers, printers, smartphones, and other devices to communicate with each other and access the Internet wirelessly.
In any given RF region that contains multiple wireless devices, only one device can transmit data a time (although various devices may listen at the same time). This requires that all other devices connected to the same endpoint or access point (AP) listen to the transmission to avoid collisions
Collision avoidance divides the wireless channels equally among transmitting nodes within the collision domain. It is supplemented by exchanging requests to send a packet

Carrier-sense multiple access with collision avoidance [14]
Carrier-sense multiple access with collision avoidance. Carrier-sense multiple access with collision avoidance (CSMA/CA) in computer networking, is a network multiple access method in which carrier sensing is used, but nodes attempt to avoid collisions by beginning transmission only after the channel is sensed to be “idle”.[1][2] When they do transmit, nodes transmit their packet data in its entirety.
CSMA/CA is unreliable due to the hidden node problem.[3][4]. CSMA/CA is a protocol that operates in the data link layer (Layer 2) of the OSI model.
– Carrier Sense: prior to transmitting, a node first listens to the shared medium (such as listening for wireless signals in a wireless network) to determine whether another node is transmitting or not. Note that the hidden node problem means another node may be transmitting which goes undetected at this stage.
CSMA/CA – Carrier Sense Multiple Access with Collision Avoidance [15]
CSMA/CA – Carrier Sense Multiple Access with Collision Avoidance. CSMA is a basic method that controls the communication of multiple participants on a shared and decentralized transmission medium
While CSMA/CA is mainly used in wireless networks, CSMA/CD was developed for Ethernet, and CSMA/CR is used in controller area networks (CAN), which are mainly used in cars and machines.. To understand exactly what is behind Carrier Sense Multiple Access with Collision Avoidance, it makes sense to look at the components individually:
The carrier status detection checks the channel any time, and data is not sent until it’s available.. – Multiple access (MA): Several stations share a transmission medium
CSMA/CA vs CSMA/CD: What’s the Difference? [16]
It’s amazing how multiple network computers send data to one another without catastrophic packet collisions. You might expect all kinds of problems, considering the millions of data packets transmitted on your average network
In this post, we will learn the difference between the two approaches.. The technology behind computer networks’ consistent performance is something called Carrier Sense Multiple Access (CSMA)
When transmitting packets of data, you want to minimize packet loss and maintain data integrity on the network. The desire here is to reduce the chance of corrupt data and other undesirable behavior like disconnections and network failures.
