IEEE802.11a standard and the European equivalent HIPERLAN/2 are two similar concepts for broadband wireless LANs (WLAN) in the 5 GHz band. Both standards are based on the multicarrier modulation technique OFDM (orthogonal frequency division multiplexing) combined with convolutional channel coding. The baseband modulation schemes of both standards are very similar‚ which simplifies implementation considerably. Challanges and difficulties considered in this paper regard both systems. Except for slight differences

43 DATA COMMUNICATION AND NETWORKING 1. Introduction Data Communication is a system consisting of carries and related devices used to transport datafrom one point to another. Communication means to convey a message‚ an idea‚ a picture or speechthat is received and understood clearly and correctly by the person for whom it is conveyed. Ancient Methods of Communication and Their Demerits – Message were sent in olden timeseither through horse riders or by using pigeons. There was no surety that

1. Define Modulation Modulation process of putting information onto a high-frequency carrier for transmission. 2. What is carrier frequency? In essence‚ then the transmission takes place at the high frequency (the carrier) which has been modified to “carry” the lower-frequency information. 3. Describe the two reasons that modulation is used for communications transmission. The modulated stage accepts two inputs‚ the carrier and the information (intelligence) signal. 4

Computer Networks NETWORKING CONCEPTS Network A network is basically an interconnection of various points to make a connected system e.g Road‚ Telephone‚ Social Data Network A computer network therefore refers to an interconnection of computers and other peripherals by use of a communication link Peer to Peer Networks In a peer-to-peer network‚ all computers are considered equal; they all have the same abilities to use the resources available on the network. Peer-to-peer networks are designed

’Communication -- - the process of transmitting and receiving ideas‚ information‚ and messages. The rapid transmission of information over long distances and ready access to information have become conspicuous and important features of human society‚ especially in the past 150 years.’ The encyclopedia definition of communication encompasses the ideas of exchanging a variety of messages with others. This is important to remember when looking at communications within an organization. The whole process

EX-03 CHAPTER 3- Exercises Solutions 1. Baseband transmission means sending a digital or an analog signal without modulation using a low-pass channel. Broadband transmission means modulating a digital or an analog signal using a band-pass channel. 2. Optical signals have very high frequencies. A high frequency means a short wavelength because the wavelength is inversely proportional to the frequency ( = c/f)‚ where c is the propagation speed in the media. 3. The frequency domain of a voice signal
