  • Wireless Mesh Networks are well-suited for providing broadband wireless access in areas that traditional Wireless LAN systems are unable to cover and where the seamless voice and mobility capabilities of cellular systems aren’t required. Key characteristics: Auto-discovery: the ability to automatic detect the presence of a new node in the network and incorporate it into the routing tables allows the operator to extend the coverage and capacity of the system with a minimum of effort. A well-designed ad hoc network is virtually “plug and play” Auto-configuration: similarly, allowing the nodes to configure themselves and negotiate directly with their neighbors reduces the additional cost and effort associated with more traditional, centralized operational support systems (OSSs) Mesh topology: the mesh-like pattern of links formed among the nodes in the network is inherently more robust than classic hierarchical or star network configurations, since (more often than not) the network has multiple routes available between any two nodes. The network automatically routes around any congestion or failure in the network Wireless interconnection: the use of wireless links between nodes in the network allows nodes to be installed wherever they are needed, without being concerned about the availability or ongoing costs associated with wired backhaul links Advantages: Rapid network deployment: this is a result of the auto-discovery, auto-configuration and wireless aspects of the system. A new network can be created merely by powering up 2 nodes. As new nodes are added, the network automatically adjusts to make optimal use of them Reduced infrastructure costs: the reduction or elimination of OSS components to manage the network, and the elimination of wired backhaul dramatically reduce the amount of equipment required to serve a given area, compared to current WLAN and cellular solutions Reduced engineering and operational costs: virtually no planning nor ongoing maintenance efforts are required, other than placing the nodes within range of one another and replacing faulty units. The primary engineering activity relates more to ensuring that the capacity of the network (and especially the transit links) is sufficient to meet the demands Increased network reliability: the availability of multiple routes through the system ensure that user traffic can be routed around faults or impairments in the network. In addition, traffic can be distributed across different routes to better balance traffic flow through the network
  • For specific examples on installation & commissioning cost and operating expense savings see the following charts showing examples. Actual numbers are included for the Toronto example..
  • OFDM has arrived 802.11 a and g are commercially available 802.16 a is standardized and on a path to products in 2004 Advancement of OFDM-based standards and solutions is progressing most rapidly in IEEE Demands for higher speeds continue

  • IEEE 802.16 WMANs
    • Wireless Metropolitan Area Networks (Chaired by NIST)
    • Task Groups (TGs):
      • 802.16a (completed 1Q03)
        • New addition of MAC and PHY for 2-11 GHz, both licensed and unlicensed
        • This complements the original 802.16 (10 – 66 GHz) standard completed previously
      • 802.16c (Chairs: Ensemble Communications, Nokia)
        • Developing a series of three conformance standards in support of the 10-66 GHz air interface specified in IEEE Standard 802.16
      • 802.16d (Chair: WiLan Inc)
        • Ratifying set of 802.16a system profiles to reduce scope of standard to specific, interoperable, subsets.
        • Contributions for 256OFDM will be developed and brought in by WiMAX forum for ratification by 802.16d.
        • Targeting to add “hooks” to 802.16d for forward compatibility to 802.16e standard
      • 802.16e (Chairs: InterDigital, WiLan Inc)
        • Mobile Wireless MAN PAR approved December 2002.
        • Likely to proceed with deliberate speed
        • Likely to be based on OFDM, potentially with MIMO
    • Potential Applications:
      • Point-Multipoint backhaul, including Hotspot backhaul
      • Residential and SOHO DSL-like service
    Nortel Networks participates in 802.16 One 802.16a chipset on the market today Products expected to reach market in 2004
  • WiMAX Forum
    • Seen as analogous to Wi-Fi Alliance in WLAN space:
      • Being pushed hard by Intel and Fujitsu
      • Strong push to focus on base profile of 256 OFDM w/o many options
      • Promote interoperability, certify conformance – I.e. interoperability certification
      • Marketing, branding, build industry momentum
    • WiMAX membership includes Intel, Fujitsu & several others:
      • New members include Motorola and Atheros
    • 802.16 history is a hodgepodge of point to multipoint solutions for 2 to 66 MHz:
      • The multitude of options result from an attempt to address several markets (with regulations specifics) and failure to reach a compromise
      • No mandatory configuration makes interop difficult
    • WiMAX aims to define a set of system profiles that:
      • Reduce scope of implementations
      • Target specific market segments
      • Guarantee interop
      • Allow higher volumes and a more competitive market
      • Are ratified by IEEE 802.16d
  • IEEE 802.20 MBWA
    • Mobile Broadband Wireless Access
      • PAR was chaired by Flarion
      • PAR and separation from 802.16 driven by Mark Klerer (ex-Nortel, now Flarion)
      • Current leadership associated with Qualcomm, Lucent and NTT-DoCoMo
      • Goal is to develop low latency packet data “cellular-like” service
      • Technology direction unclear
    • Potential Threat to CDMA and UMTS?
      • Target Bandwidth:1.5MHz and 5 MHz
      • Target Spectrum: PCS allocation
    • Snapshot from May 2003 and November IEEE 802.20 meeting
      • Working methods/processes - 3 new correspondence groups created:
        • channel/traffic model
        • system requirements
        • evaluation criteria
      • Requests for more time to create this standard
      • Some recognition of (Nortel’s view of) need for differentiation from 3G
        • To be useful, 802.20 must provide greater value than 3G standards
      • New leadership is not seen as favorable to Flarion technology
    Nortel Networks participates in 802.20 Too soon to tell whether 802.20 will amount to much May be preempted by 802.16e
  • IPT Prioritized list of Security work
    • OS Hardening, including documenting the ports and services used on the element
      • OS hardening work completed for some NEs and EMSs. Work required to document ports and services.
    • Data encryption. Methods include encrypting the protocol (SSH, SSL, SNMPv3) and/or encrypting the entire path (IPSec). Pros and Cons to both, and we believe both are required in some areas of the solution.
      • Very few NEs have implemented encryption. Large amount of work/resources required.
    • Strong Passwords, centralized control
      • MFT Framework implementing a Radius based solution in FWK 3.3 (delivers with PWI V5 – CuR 2005). A good starting point, but large amount of work/resources required to implement on the NEs, and integrate with all OAM applications. Work can be phased into multiple releases.
    • Secure Logs/Audit logs, support for security trouble shooting by maintaining an audit trail of user activities.
      • Framework in place, but requires implementation on all NEs. Work can be phased into multiple releases
    Security
  • CTIA stated Priorities
    • OS Hardening is considered fundamental - Customers want documentation of valid services and ports, and want all unused services and ports disabled and closed
    • Authentication with strong passwords and centralized administration
    • Encryption of credentials – don’t send passwords in clear text
    • Authorization – multiple levels of user access depending on role
    • Integrity of Data – ensure data received is the data sent
    • Session Logging – generate audit trails to enforce user accountability
    • Encryption of data – Prevent theft of data, fraudulent spoofing
    • Don’t store session logs in clear text – again to enforce accountability
    Security
  • In Closing…..
    • 3G has arrived…
    • WLAN integration starting to take place with WWAN
    • Continued Development of Standards Continuing
    • Only Time will Tell on which standards are accepted by the Market
    • Many standards have come and gone in the past
    • Make no mistake – wireless access is a must!
