Nortel Wireless Mesh Network Portfolio
Overview
Nortel Wireless Mesh Network solution is a new, enhanced WLAN architecture that redefines the boundaries of WLAN technology, enabling wireless connectivity for enterprises and public end users.
The Nortel Wireless Mesh Network is well suited for providing broadband wireless access in areas that traditional WLAN systems are unable to cover and where the seamless voice and mobility capabilities
of cellular systems are not required. Nortel Wireless Mesh Network includes a peer-to-peer architecture - with smart antennas, integrated routers and adaptive routing as well as security capabilities - to backhaul data wirelessly to wired broadband networks. With powerful business models for government applications, enterprises and service providers, this latest addition to Nortel WLAN portfolio brings together the best of our wireless and wireline solutions for reliable wireless access.
The Nortel Wireless Mesh Networks solution consists of these key elements:
• Nortel Wireless Access Point 7220 - A wireless mesh is formed among multiple Nortel Wireless Access Point 7220s by utilizing auto-discovery and self-routing technology. This unit also acts as a WLAN Access Point for user access.
• Nortel Wireless Gateway 7250 - This device provides user mobility and data traffic security between access points.
• Nortel Wireless Bridge 7230 — A cost effective point-to-point broadband wireless transmission system, it provides Ethernet services for transmission over 5.8 GHz unlicensed bands and is suitable for
deployment in FCC regulated countries.
• Nortel Enterprise Network Management System - Software management capability provides centralized facilities for monitoring and managing network operations.
Typical Applications
Areas where traditional WLAN systems are unable to cover and where the seamless voice and mobility capabilities of cellular are not required. Some examples are:
• Higher education — cost-effective campus-wide university coverage for faculty and students
• Manufacturing — wireless data applications for improved efficiency and overcoming building infrastructure challenges
• Public areas — broadband connectivity for transient users with 802.11 wireless enabled laptops and PDAs in airports, hotel, convention centers, shopping malls, sporting venues, special events, etc.
Key Points
• Uses standard IEEE 802.11 technology
• Enables WLAN deployment and simplified coverage for vast open areas, both indoor and outdoor
• Brings “hotspots” together into a community area network (CAN), providing larger homogenous coverage and seamless mobility within the CAN
• Eliminates the need for extensive Ethernet cabling or leased lines through the use of wireless communication between access points in the mesh network
• Enables wireless backhaul using directional antennas in a circular array; directional antennas have a high gain and provide greater coverage and throughput while minimizing interference
• Auto-configuration and centralized management capabilities to simplify network operations
• Avoids service outages by providing efficient routing using auto-discovery and self-healing algorithms
• Provides a highly secure environment for both end users and the networkFeatures and BenefitsNortel Wireless Mesh Network solution provides a cost-effective method for extending WLAN coverage
more broadly into business and end user markets:
• Based on unlicensed 802.11 technologies, the Nortel Wireless Mesh Networks solution allows service providers to add wireless broadband services to their portfolio without requiring them to invest in expensive radio spectrum.
• Building on existing and growing acceptance of using wireless technology for end user and business applications, service providers and enterprises alike can leverage consumer devices (wireless handsets, personal communications devices, etc), that are inexpensive, readily available and already exist in large numbers in the market.
• The Nortel Wireless Mesh Network solution uses wireless links for backhaul, allowing enterprises or service providers to install WLAN with a minimal amount of new or additional Ethernet cabling or other backhaul facilities.
• In the case of service providers, using wireless links for backhaul reduces the ongoing costs of leasing facilities for data transport.
• Service providers and enterprises can now expand WLAN coverage to areas where network limitations or cost made it prohibitive with other solutions.
The Nortel Wireless Mesh Network solution provides a secure platform for WLAN access and is highly flexible in terms of capacity, coverage and availability:
• The solution includes the latest security standards to protect user access and protects both the network and the user by providing security on the wireless transit links between access points.
• Since the Nortel Wireless Mesh Network solution provides self-organization and auto-configuration capability, increasing capacity, coverage, and/or availability simply means deploying more Nortel Wireless Access Point
7220s.
• Minimal cabling is required, so setting up temporary installations for emergencies, special events, etc., is easy to do.This solution provides specific benefits for enterprises, service providers, wireless Internet service providers (WISPs) and multi-layers of government (federal/municipal).
• Enterprises — the Nortel Wireless Mesh Network solution is ideal for WLAN coverage of large open areas, both indoor and outdoor, and should be considered in areas where Ethernet cabling does not exist and is prohibitive to install.
• Service providers — the Nortel Wireless Mesh Network solution enables new revenue opportunities through differentiated service offerings, extended service reach, and increased usage of high speed data into existing and new markets.
• WISPs — the Nortel Wireless Mesh Network solution offers rapid, flexible and cost-effective deployment to provide community-based high-speed wireless Internet access as an enhancement or alternative to dial-up, DSL, or cable modem service.
• Government — the Nortel Wireless Mesh Network solution allows federal, municipal, or homeland security entities to cost-effectively leverage the benefits of WLAN access in a wide range of areas.
Some examples are:
- Improved productivity of public safety and utility employees by moving the office to the field.
- Enhanced security coverage at ports and border crossing areas.
- Permanent or temporary wireless access for disaster recovery, command posts, etc.
