two reasons 1. In wireless each station has one antenna for both sending and receiving. hence we cant use the same antenna for both transmitting and at the same time detecting collisions. Further even if we have two antennas, it will be difficult to detect collision. because the transmitting signal power will be much higher than the incoming signal. hence if the sender senses signals it will fairly get a net result (an addition) of its transmitted signal and any other signal transmitted by others. it may be that its own signal is so much powerful than others that it will not recognize any collision. 2. In wireless, only the receiver is in problem. not the transmitter. so detecting for collisions at the senders end does not really make sense. we need to detect collision at the receivers end. the sender is not able to tell it whether there is a collision in receivers end. sukarna_barua@Yahoo.com
What else can I help you with?
How can I hook up wireless computer to an wired network?
You will need to add a wireless access point to the wired network.

What is the function of a bridge?
A bridge is a way to connect two networks. For example, if a user has two or more computers connected to a wired network, and one of those wired computers is connected to a wireless network, the computer connected to both the wired and wireless networks could be used as a bridge. With the bridged networks, the wired computers could access the wireless network.
Give two reasons why network might use an error correcting code instead of error detection and retransmission?
1)Time taken to error correcting is less than doing detection and retransmission. Bandwidth use will be less. 2) In detection and retransmission if back messaging occurs the bandwidth will be more
Which network devices reduce the size collision domains and provide error detection?
switches and your mama.!! lol haha

Buya an usb wireless adapter.
What is the least secure and if possible should NOT be used on a network?
Unsecured wireless network without MAC filter.
What has the author AS Rana written?

Is it possible to send an email in Microsoft Outlook over a Wireless Network?
As long as the network is connected to the internet, yes.
Why 802.11use acknowledgements but not in wired Ethernet?
Two scenarios exist where a wireless network might not know if a frame was successfully delivered, that do not exist in a wired network. First, a weak wireless signal could mean that the sender may not be capable of transmitting and listening at the same time, and this makes collision detection impossible. Second, fading or the hidden-terminal problem could mean that interference occurred during the transmission without the sender knowing.
What happens when collision occur in anetwork?
In a network, collisions occur when two or more devices transmit data at the same time on the network, resulting in a data packet being corrupted. When a collision occurs, the devices involved must wait for a random amount of time before retransmitting their data to avoid another collision, which can impact network performance and throughput. Modern networks use techniques like collision detection and avoidance to minimize the occurrence of collisions.
Definition of wireless sensor network in wikipedia?
Difference between wireless network and wireless sensor network?
Do you need a network if you go wireless?
Yes. "Going wireless" simply means that you "use a wireless network".Yes. "Going wireless" simply means that you "use a wireless network".Yes. "Going wireless" simply means that you "use a wireless network".Yes. "Going wireless" simply means that you "use a wireless network".
When will be collision takes place in Network Switch?
Collision hardly takes place in todays intelligent switches. According to my knowledge all swicthes in todays era are working on CSMA-CD i.e. Carrier Sense multiple access - collision detection. Every station in a network sense the carrier so the switch before maintaining any communication.
Can you use your laptop as a wireless network adapter for Xbox live?
Yes, it is possible to use a laptop as a wireless bridge for xbox live.
Determine min frame size by collision detection interval?
The network doesn't need to see an entire frame before determining a collision has occured; as soon as it detects a transmission after or during the process of sending a frame there is a collision. Theoretically then it could be a part of a frame as small as a byte.
