Students and Faculty Love WirelessStudents and Faculty Love Wireless
Availability of content anytime and anywhere
Students expect and demand wireless access for their mobile lifestyle
Faculty likes the collaboration, creativity fostered by wireless
Proliferation of personal WiFi enabled devices
Page 18
Why Network Admins Prefer WirelessWhy Network Admins Prefer Wireless
No building renovation needed, no pulling new cables in historic buildings
Easily installed in common areas (quad, union, gym, cafeteria)
Easier to deploy, manage and troubleshoot
Easy to expand as needs grow – expansion costs (few APs) small enough not to require formal budgetary approval
Page 19
Considerations for EducationConsiderations for Education Financial
Lower cost of deployment Deploy “Thin” APs & eliminate site surveys
Leveraging existing infrastructure Don’t upgrade your Layer 2 infrastructure
Ease of Management Centralize management and control
Self-healing, self-calibrating RF environment Reduce VLAN proliferation
Centralized architecture means no need to configure VLANs all over existing network
Security Identity based access control
Students, Faculty, Staff all have pre-assigned privileges that follow users
Safeguarding against intrusion Control access to wireless Build robust systems that can resist students who like to
“experiment” Provide comprehensive end-point security Filter network traffic for viruses and unauthorized content

802.11e Task Group802.11e Task Group
Group charter is Quality of Service Close to completing work that will allow for improvements in
the way multimedia and prioritized traffic classes are handled.
802.11e enhances the MAC layer with a coordinated time division multiple access (TDMA) construct.
Adds error-correcting mechanisms for delay-sensitive applications such as voice and video.
802.11e is especially well suited for use in networks that include multimedia capability. It offers all subscribers high-speed Internet access with full-motion video, high-fidelity audio, and Voice over IP

802.11i Task Group802.11i Task Group
Group charter is Enhanced Encryption 802.11i is the security standard for Wi-Fi networks that
upgrades WEP. 802.11i has all the abilities of WPA and adds the
requirement to use Advanced Encryption Standard (AES) for data encryption.
The Wi-Fi Alliance uses the nomenclature of "WPA2" when referring to 802.11i

WiMAXWiMAX
WiMAX is the recently approved IEEE 802.16 wireless metropolitan area network (MAN) standard .
WiMAX provides connectivity up to several miles as opposed to a couple hundred feet for 802.11a/b/g.
Less expensive than cellular infrastructure equipment. Some industry experts claim that WiMAX could become a
threat to the cell phone industry, which is investing in 3G to offer advanced mobile data services
WiMAX will provide backhaul for 802.11 networks

802.11s Task Group802.11s Task Group
Group Charter is Mesh Networking Every device in a network becomes capable of repeating or
relaying data to a node that is farther away from the access point
MESH becomes a method for extending the reach of a given infrastructure.
802.11s aims to define a MAC and PHY for meshed networks that improve coverage with no single point of failure.
In such networks, 802.11 cellular WLAN access points relay information from one to another, hop by hop, in a router-like fashion. As you add users and access points, you add capacity.
Adding nodes becomes a scalable and redundant endeavor Meshed networks can serve as indoor or outdoor networks
run wireless ISPs or enterprises with large outdoor deployments.

UWBUWB
Similar to Bluetooth but around 100x faster. Ultra-wideband or UWB is used to transmit data at high
speeds over very short distances; making UWB perfect for the home market.
Main challenge: UWB works across a wide range of frequencies as opposed to most other networking and consumer electronic technologies which are assigned a narrow band of spectrum.
The Department of Transportation has also raised concerns about UWB interfering with the GPS systems essential for flying.
Despite concerns, UWB is moving forward in the home networking market due to its fast transmission rates.

IMSIMS
The IP Multimedia Subsystem (IMS) is an IP multimedia and telephony core network that is defined by 3GPP and 3GPP2 standards and organizations based on IETF Internet protocols.
IMS is access independent as it supports IP to IP session over wireline IP, 802.11, 802.15, CDMA, packet data along with GSM/EDGE/UMTS and other packet data applications.
IMS is a standardized reference architecture that consists of session control, connection control and an applications services framework along with subscriber and services data.
