OSI layer order (wireless and 3G)

  ms79ms 20:59 05 Apr 14

hi, every body please help me with the question below: A service engineer who is at a customer's premises needs to connect to the new company server to check a diagram for a device he is servicing. Identify and explain the key data communication standards and protocols that will be used during this communication. You may assume that the engineer has a wireless, 3G based Internet connection available from his van. You should name each protocol that is used, in OSI layer order and briefly outline what this particular protocol does in this example. It is very important that your answer fits this example and is not just a generic description of the protocols.

best regards marina
