So now if one of the AP is on channel 1 and the other one is on channel 2, then there won’t be any collision and they can now transmit the frame independently. Question P6. Answer. If there are two wireless station trying to transmit, let’s say if A is transmitting data D1. While this transmission is going say another wireless station B wants to transmits its data D2, but as B detects that there is another transmission ongoing it won’t transmit its data D2. As soon as A finishes transmitting data it has two option either wait for some time and then transmit again or select a backoff value. If it chooses a backoff value it will give an opportunity to station B to transmit its data. And hence to give an equal opportunity to transmit. Question P7. Answer. The station wants to transmit data of 1000 bytes i.e. 8000bits. Let us consider maximum transmission rate of 802.11b i.e. 11Mbps. Here the header is of 256 bits. So the entire frame will be of header plus data i.e. 256 + 8000 = 8256 bits. So the time required to transmit the frame is 8256bits/11Mbps i.e. 751 microseconds. And time required to transmit the control frame is 256 bits/11 Mbps i.e. 23 microseconds. So the time required to transmit and receive the acknowledgement would

    I believe that the survey presented in the Unit 2 reading assignment revealed several blind spots concerning my individual academic skills. I was startled to discover some of my individual weaknesses revealed in the survey. The survey was insightful and enlightening, as I realized that I have previously ignored some critical areas addressed. I realize that focusing on my weaknesses can compound the difficulty of achieving academic success (Bethel University, 2014). Developing my weaknesses and converting them to strengths will significantly improve the likelihood of my academic and professional success.

    The SIFS( Shortest Inter-Frame Space),derives the time between the last transmission and high priority transmissions such as positive acknowledgments(ACKs),Clear-To-Send(CTS)frames,polling responses, continuation frames in a burst transmission. priority is given to the positive ACK frames so that a station which has just completed the reception of a frame can give immediate feedback to the sender. RTS and CTS frame coordinate correspondence between sets of stations so that different stations know not the medium to be free for the time of the exchange .This is one of the reasons for why the control frames have priority over normal data transmissions. If a station finished transmitting a frame and has enough time left to send an additional frame, it is allowed to send after a SIFS.

    Answer1: When the transmission speed of ten megabits per second, the broadcast time of nine bits / 8x106 bits / second = 1 microsecond a large solitary byte. A good bit in connection with the 200 meters during optical fiber offers a large propagation time involving 200 meters / 2x108 meters / second = 1 microsecond. And so the area associated with 500 bytes requires 501 microseconds to arrive definitely with the recipient.

Likewise, Full duplex also increases the maximum distance supported for fiber cables between two data terminal equipment (DTE) devices for up to 2 km. The IEEE 802.3z standard describes three types of transmission; 1000BaseSX over multimode fiber optic cable, 1000BaseLX over single-mode fiber

Although the technology has been standardized for many years, providing the wireless network security has become a critical area of concern. Due to the broadcast nature of the wireless communication, it becomes easy for an attacker to capture wireless communication or to disturb the normal operation of the network by injecting additional traffic [7]. WLANs are very flexible and topologies configured based on the application. Some possible uses of WLANs are mentioned

    Wireless protocols have evolved over the years, there are many new models being created that push more bandwidth data using wireless technology. In most cases the older, wireless models are more sensitive to interference, which in turn result for the protocol to fallback to slower modes for the data to get though (insert). According to an article that PCmag.com wrote, there are three limitation to 802.11b limited bandwidth, radio interference from other devices and networks, and security concerns. Introducing this to an outside environment is going to cause each station transmitting will take longer to send its signal, which means it more likely that the transmitter or other interference will corrupt the packet resulting in packet loss and retransmission of the packet ("802.11b Pros and Cons-Fast Wireless Networking -| PCMag.com," n.d.).
