Protocols

Type of mobile device available
there are lot of diffenent moblie device which we can access the internet on the go. they are a range of this devices for all can of user.
this device are
Mobile/cell phones
Smartphones
PDA
Portable games consoles
Netbooks.




What protocol will it use


WAP or wireless Application Protocol adds a new dimension to the Internet e.g. mobility. With a smartphone or a laptop computer that supports WAP you can access the internet, read emils and check your bank account at any time any where. You can play games online with your friends, check the weather anywhere at any time.The world wide web is always with you all the time. It also includes services such as downloading songs, documents and news, improved ways of controlling outgoing and incoming calls and it will make mobile telephony even easier. To access WAP services you need a WAP product. Besides the WAP compatibility, WAP products have a large full graphic display and include a micro browser because some wifi hotspots you have sign in to use there network. The basic function of WAP is for mobile phones to be able to communicate with a server installed in the mobile phone network. It brings together the internet and telecommunications together. Of course, as all new technologies, come out the protocols will change. 


The OSI for Wi-Fi Devices


7 Application Web Browser, Email, Print Serivces,  SIP, SSH and SCP, NFS, RTSP, Feed, XMPP, Whois, SMB; DNS; FTP; TFTP; BOOTP; SNMP;RLOGIN; SMTP; MIME; NFS; FINGER; TELNET; NCP; APPC; AFP; SMB

6 Presentation  XDR, ASN.1, SMB, AFP, NCP, MIDI, HTML, GIF, TIFF, JPEG, ASCII,
                         EBCDIC

5 Session     TLS, SSH, X.225, RPC, NetBIOS, ASP, Winsock, BSD


4 Transport  TCP, UDP, RTP, SCTP, SPX, ATP
                    Gateway, Advanced Cable Tester, Brouter  

3 Network     IP, ICMP, IGMP, BGP, OSPF, RIP, IGRP, EIGRP, ARP, RARP, X.25, NETBEUI
Brouter, Router, Frame Relay Device, ATM Switch, Advanced Cable Tester, DDP


2 Data Link  Ethernet, Token ring, StarLAN, HDLC, Frame relay, ISDN, ATM, 802.11 WiFi, FDDI, PPP, Bridge, Switch, ISDN Router, Intelligent Hub, NIC, Advanced Cable Tester, ARCNET, LocalTalk, FDDI, ATM. NIC Drivers: Open Datalink Interface (ODI), Network Independent Interface Specification (NDIS)


1 Physical     NIC, Twisted Pair, Coax, Fiber Optic, Wireless Media, Repeater, Multiplexer, Hubs, (Passive/Active), TDR, Oscilloscope, Amplifier, Carrier pigeon

TCP LAYERS
4 Application (OSI - Layers5 through 7)          
HTTP, FTP, DNS
(Routing protocols like BGP and RIP, which for a variety of reasons run over TCP and UDP respectively, may also be considered part of the Internetwork layer)

3 Transport (OSI - Layers4 and 5)         
TCP, UDP, RTP, SCTP
(Routing protocols like OSPF, which run over IP, may also be considered part of the Internetwork layer)

2 Internetwork  (OSI - Layer 3)               
For TCP/IP this is the Internet Protocol (IP)
(Required protocols like ICMP and IGMP run over IP, but may still be considered part of the Internetwork layer; ARP does not run over IP)

1 Link             (OSI - Layers 1 and 2)       
Ethernet, Wi-Fi, MPLS, etc.
