ISO seven layer model
1: Physical layer
moves bits using voltage, current, light, etc.
2: Data Link layer
bundles bits into frames and moves frames between hosts on
the same link
3: Network layer (e.g. IP)
Makes routing decisions
uses destination address in packet
Forwards packet hop by hop
encapsulates network layer packet inside data link layer
frame
different framing on different underlying network types
Unreliable
Single address space for the entire internetwork
4: Transport layer (e.g. TCP)
end to end transport of datagrams
encapsulates datagrams in network layer packets
adds reliability by detecting and retransmitting lost
packets
uses acknowledgements and sequence numbers to keep track
5: Session layer
not used in the TCP/IP network model
6: Presentation layer
not used in the TCP/IP network model
7: Application layer
Uses the underlying layers to carry out work

Hi I have 10+ years of telecom application development experience ( telecom billing product -call control (ISUP/INAP/CAMEL call handling), short message routing application, telecom tools development). I am very strong in C++/Unix , core java and advanced oops design. Recently I have undergone a training in 3G mobile protocol developement. I have very good knowledge about WCDMA, its various layers and gone through 3GPP technical specs. Now I am looking for 3G mobile development opportunities. I am finding very difficult to get it, as I don't have the relevant experiences on 3G development. Please advice me on this to enter into mobile protocol development.
A periodic composite signal with a bandwidth of 3000 Hz,is composed of two sine waves. First one has a frequency of 100 Hz with a maximum amplitude of 30 V, the second one has a maximum amplitude of 10 V. Draw the bandwidth.
