- The amateur radio community uses at most 25kHz of bandwidth in the VHF band that spans 144MHz to 146MHz. Two different users simultaneously transmit their voices without interfering with each other by using the 144.025MHz and the 145MHz frequencies, respectively. How many users can simultaneously transmit without interfering with each other over the given VHF band?Use the following cell phone airport data speeds (Mbps) from a particular network. Find Upper Q 3 Upper Q 3 equals Mbps (Type an integer or a decimal. Do not round.)An Internet-service provider company uses a fiber-optic network to transmit data between locations. Data are carried through fiber-optic cables and switching nodes. A portion of the company's transmission network is shown here.

- 4. When a wireless mobile user moves to a new cell (by leaving its current cell) while communicating, the user requests a new channel from the new cell so that it can continue its communication. This is known as a handoff call. Assume that each cell has c channels, and each channel can only be assigned to one user/call at a time. When all the channels in the new cell are being used (i.e., all channels are being assigned to ongoing calls), the handoff call has to be terminated or blocked. That is, the new base station servicing the new cell cannot allocate a channel to the handoff call. Assume the interarrival time between any two consecutive calls is exponentially distributed with mean t, and the channel holding time (i.e., call duration) is also exponentially distributed with mean . The objective of this problem is to derive the blocking probability of a handoff call to the new cell. (a) Model the handoff process at the new base station using a queueing system. (b) Show a Markov chain…An Internet service provider sets it's base rate for data transfers in a given month according to market conditions. Customers are billed for data transferred in a given month as follows: Transfers up to and including 100 Gigabytes (GB) are charged this base rate only. Transfers over 100 GB up to and including 1000 GB are charged the base, plus an additional 15% of the base, plus an additional $0.07 per GB for each GB over 100GB. Transfers above 1000 GB are charged simply twice the base. (Use Python) User the Design Reciple to write three functions (bill_small, bill_medium, bill_large) which each likewise consume an amount of data and a base value, then calculates the charge according to the above schemes. Bills should be rounded to the nearest cent. Include docstrings! E.g., bill_medium will expect a number between 101 and 1000, and return the base+(15% of base)+$0.07 x (GB over 100). Write at least one assert_equal test for each function assuming a base rate of $80.00. Write one…Path: p Words QUESTION 13 A Television broadcasting service uses a single coaxial cable with a bandwidth of 680 MHz to transmit multiple TV channels to their subscribers.
