Why neighbouring stations are assigned different frequencies in cellular system?

Why neighbouring stations are assigned different frequencies in cellular system? Correct Answer To minimize interference

  •  In the cellular concept, frequencies allocated to the service are re-used in a regular pattern of areas, called 'cells', each covered by one base station.
  • In mobile-telephone nets, these cells are usually hexagonal. In radio broadcasting, a similar concept has been developed based on rhombic cells.
  • To ensure that the mutual interference between users remains below a harmful level, adjacent cells use different frequencies.
  • In fact, a set of C different frequencies {f1, ..., fC} are used for each cluster of C adjacent cells. Cluster patterns and the corresponding frequencies are re-used in a regular pattern over the entire service area.

Consider the string abbccddeee. Each letter in the string must be assigned a binary code satisfying the following properties: 1. For any two letters, the code assigned to one letter must not be a prefix of the code assigned to the other letter. 2. For any two letters of the same frequency, the letter which occurs earlier in the dictionary order is assigned a code whose length is at most the length of the code assigned to the other letter. Among the set of all binary code assignments which satisfy the above two properties, what is the minimum length of the encoded string? 
How does a host on an Ethernet LAN know when to transmit after a collision has occurred?
1. In a CSMA/CD collision domain, multiple stations can successfully transmit data simultaneously.
2. In a CSMA/CD collision domain, stations must wait until the media is not in use before transmitting.
3. You can improve the CSMA/CD network by adding more hubs.
4. After a collision, the station that detected the collision has first priority to resend the lost data.
5. After a collision, all stations run a random backoff algorithm. When the backoff delay period has expired, all stations have equal priority to transmit data.

Can a weekly market address all the needs of a family? Why or why not? ii. Compare and contrast the characteristics of a weekly market and a permanent shop. iii. Are you likely to find a well-known brand as part of a weekly market? Why or why not? iv. Can any seller increase their price a lot compared to other sellers in a weekly market? Why or why not?
In a certain number of days, 10 workers were assigned to complete a task. Since some of the workers have not worked all these days, only 25% of the task was completed after 15 days. From the 16th day onwards when all 10 started working, the percentage of the total work that was completed at the end of the assigned days was 62.5%. How many days were assigned initially?
