  16. Education Applications

  17. Students 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

  18. Why 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

  19. Considerations 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

  20. Emerging WLAN Standards

  21. 802.11e 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 • Software Upgrade for Aruba Mobility Controllers

  22. 802.11i 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 • Software Upgrade for Aruba Mobility Controllers

  23. 802.11n Task Group • Group Charter is High Throughput • This group will define the next physical-layer specification allowing throughput speed in excess of 100 Mbps. • Ratification expected in 2006 • 802.11n is planned to be backwards-compatible with legacy 802.11b/g wireless hardware • Pre-standard MIMO chipsets are shipping from Airgo Networks • Software Upgrade for Aruba Mobility Controllers

  24. The Wireless Voice Opportunity • Voice is the most widely deployed wireless application today • Corded and cellular technologies not suited for education environments • Coverage • Portability • Telephone system integration • Cost • Wireless and VoIP technologies are lowering cost of deployment

  25. Evolution of the Wireless Edge

  26. Mobile Instruction Mobile Point of Sale Mobile Connectivity Users Demands Mobility User Installed – Lose Control 1 4 3 2 OR Voice Mobility Location Services RFID Solutions Compelling Economics New Applications Mobility – An Irreversible TrendThe Education IT Context

  27. What the user is using Where the user is Who the user is Mobility is All About the User USER IDENTITY USER LOCATION USER DEVICE/APPLICATION

  28. Mobility Changes Everything • The edge of the network will become wireless • Mobility creates the requirement for an interior security solution • Mobile applications are changing the way educational institutions compete

  29. Aruba Value Proposition A Converged Solution for Mobility, Security and VOIP • Deliver a competitive advantage • The industry’s most secure mobility system • Fix security with a network-based approach • A single centralized solution for interior security • Enable convergence over wireless • Mobile VoIP eliminates closet PoE upgrades • Eliminate network upgrades • Save millions of dollars • Reduce operational costs • Centrally manage change with a programmable architecture

  30. Backup

  31. WiMAX • 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

  32. 802.11s 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. • Software Upgrade for Aruba Mobility Controllers

  33. UWB • 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.

  34. IMS • 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.

  35. Group Charter is Radio Resources Service operators and enterprise customers are expected to deploy the features coming from this group to better manage the connections between wireless devices and access points/gateways. The proposed standard provides measurement information to make wireless networks more efficient. Enables standards-based applications for PDAs and other wireless edge devices Software Upgrade for Aruba Mobility Controllers 802.11k Task Group
