A TDMA system uses 25 MHz for the forward link, which is broken into radio channels of 200 kHz. If 8 speech channels are supported on a single radio channel, how many simultaneous users can be accommodated?

Correct Answer: 1000
For a TDMA system that uses 25 MHz for the forward link, which is broken into radio channels of 200 kHz. If 8 speech channels are supported on a single radio channel, 1000 simultaneous users can be accommodated as N = (25 MHz)/(200 kHz/8).

In a GSM system, 8 channels can co-exist in 200 kHz bandwidth using TDMA. A GSM based cellular operator is allocated 5 MHz bandwidth. Assuming a frequency reuse factor of $$\frac{1}{5},$$  i.e. a five-cell repeat pattern, the maximum number of simultaneous channels that can exist in one cell is

Five Lakes Publishing has a Windows 2000 network serving 200 users. A server named User_srv is used to hold users' files. User_srv is configured with a single, large NTFS volume. Every user has a home folder on User_srv. Users can also use a shared folder named IN_PROGRESS to store files for books that are being prepared. The network administrator at Five Lakes Publishing configured disk quotas for the NTFS volume on User_srv. All users have a default limit of 100 MB, and the option to deny space to users who exceed their limit has been enabled. When a user named Amy Jones attempts to save a chapter of a new book to her home folder on the server, she receives the following error message: "The disk is full or too many files are open." What should Amy do to allow this document to be saved?

A spectrum of 30 MHz is allocated to a cellular system which uses two 25 KHz simplex channels to provide full duplex voice channels. What is the number of channels available per cell for 4 cell reuse factor?

How many users or voice channels are supported for each 200 KHz channel in GSM?

A GSM cellular telephone standard requires a minimum of 9 dB rejection of interfering signal levels of -23 dBm at 3 MHz from the carrier, -33 dBm at 1.6 MHz from the carrier, and -43 dBm at 0.6 MHz from the carrier, for a carrier level of -99 dBm. Determine the required local oscillator phase noise at 3 MHz carrier frequency offset.

A cable TV service uses a single coaxial cable with a bandwidth of 860 MHz to transmit multiple TV signals to subscribers. Each TV signal is 6 MHz wide. How many channels can be carried?

Five channels, each with a 100-kHz bandwidth, are to be multiplexed together. What is the minimum bandwidth of the link if there is a need for a guard band of 10 kHz between the channels to prevent interference?

A signal containing only two frequency components (3 kHz and 6 kHz) is sampled at the rate of 8 kHz, and then passed through a low pass filter with a cut-off frequency of 8 kHz. The filter output
