This module will look at the following aspects of wireless and mobile computing.

Design a logical wireless LAN (WLAN) architecture for mobile wireless users in compliance with 802.11 IEEE standards.
-Look at the PAN architectures: Bluetooth, NFC, IR, Zigbee.
- Demonstrate knowledge in WLAN applications as they relate to EM spectrum, radio wave propagation, modulation techniques, and frequency and channel usage in wireless technologies.
-Basic multi access radio techniques, principles and evolution of FDMA (Frequency Division Multiple Access), TDMA (Time Division Mutliple Access), CDMA (Code Division Multiple Access)
-Installation of in-building and building-to-building wireless LANs that meet mobility and throughput specifications including he site survey and documentation.
-Perform hardware setup and software configuration of Cisco Aironet APs and antennas for Ethernet/Radio ports and services specific to the WLAN needs for Access Points, Bridges, Repeater, and Site Survey Client fuctionality.
-Identify, define features of, and install, directional and omnidirectional antennas in both building-to-building and in-building WLANs.
-Design and setup of WLAN security using WEP, WPA, EAP and 802.1x protocols.
-Troubleshoot WLAN performance issues using event loggings, command line utilities, and diagnostic tools.
-Basic principles of communication architectures: PSTN, PSDN and Gateways with Signalling System 7 (SS7) and Session Initiation Protocol (SIP)
-Scatternets, Ad-hoc and the routing protocol networks
-Look at the different mobile standards and leading technologies evolving from 1G to the 4G
-Short Message Service (SMS), Multimedia Message Service (MMS).
-Frequency Allocation, Handover and Bandwidth allocation, Internet Access, Internet Security, Business Applications. Fraud analysis in IP and Mobile Computing.
-Threats and vulnerabilities of wireless based networks and standard approaches to securing them against attack.

This module will be presented via the use of formal lectures which will include guided tutorial sessions totalling 32 hours. The lectures are intended to communicate the underlying theory. In the guided tutorial sessions these will cover the simulation of wireless and mobile computing and allow for discussions on the topics covered in the lectures. There will be a named academic module tutor.
This module requires students to complete assessment work in their work place. With this in mind, there will be a work-based learning agreement in place to ensure that arrangements are in place to facilitate the work-based learning.
Students will be encouraged to discuss aspects of the module within discussion forums that are part of the VLE. These forums will allow discussions with a student's peer group as well as the module tutor. Where group work is required students will be expected to utilise the VLE and other means of electronic communication to facilitate this.
In addition to completing the assessment, work-based learning will usually include working through preparatory exercises and tasks in a module work book guided by a work-based Mentor.
This work and the assignment will be discussed at regular reviews (1*30mis per learning block) with the academic module tutor.

Specialist laboratories with discrete event simulator software.
