Wireless LAN
The integration of the wireless network into KAHRAMAA wired network would
provide an added advantage in terms of ease in manageability.
Wireless is universally seen as the flexible, preferment and secure and able to
provide information quickly, where it is needed and when it is needed.
Our solution is based on products from Cisco Systems for management, control and
access.
Wireless networks must focus on four fundamental areas to be suitable for enterprise deployment:
applications, access, control, and management.
ApplicationsBusiness critical solutions, applications and tools that enhance user
productivity, collaboration and communication.
Access802.11a/b/g connectivity for WLAN clients via access points that facilitate
specialized air/RF deployment, management, and performance features. Here, the
RF environment is scanned for rogue access points, unauthorized users, and
potential intrusions as well as network characteristics that may adversely affect
network performance such as interference and coverage holes.
ControlResponsible for system-wide wireless LAN functions, such as security
policies, wireless intrusion prevention, RF management, quality of service (QoS),
and Layer 2 and Layer 3 mobility, to support business-critical wireless applications.
The control component works with access points and a management device to
deliver enhanced performance, advanced management capabilities, and network
scalability.
ManagementAllows IT managers to design, control, and monitor their enterprise
wireless network from a centralized location, simplifying operations and reducing
the total cost of ownership.

The Cisco Distributed WLAN Solution includes Cisco Aironet access points, the CiscoWorks Wireless
LAN Solution Engine (WLSE) or CiscoWorks WLSE Express management platforms and the Cisco
Catalyst 6500 Series Wireless LAN Services Module (WLSM). The Cisco Distributed WLAN Solution is
deployable in the following configurations today:
Access point only deployment for secure WLAN access using Cisco Aironet access points.
Access point + centralized management capabilities using Cisco Aironet access points and the
CiscoWorks WLSE or CiscoWorks WLSE Express.
Access point + centralized management + control through wireless integrated switches using Cisco
Aironet access points, the CiscoWorks WLSE or CiscoWorks WLSE Express, and the Cisco Catalyst
6500 Series WLSM with the Cisco Catalyst 6500 Series Supervisor Engine 720.
Cisco Centralized WLAN Solution :The Cisco Centralized WLAN Solution includes Cisco lightweight access points with a Cisco Wireless
LAN Controller, managed via the Cisco Wireless Control System (WCS), which supports advanced
location services using the optional Cisco Wireless Location Appliance. These products are based on the
recently acquired Airespace product portfolio. The Airespace acquisition helps to accelerate Ciscos goal
of wired + wireless integration and RF innovation.
The Cisco Centralized WLAN Solution is deployable in the following configurations today:
Access point + controller using Cisco 1000 Series lightweight access points and Cisco 2000 series or
4100 Series Wireless LAN Controllers.
Access point + controller + advanced management capabilities using Cisco 1000 Series lightweight
access points, Cisco 2000 Series or 4100 Series Wireless LAN Controllers, and the Cisco WCS with
optional location services.
Access point + controller + advanced management + real-time location services using Cisco 1000 Series
lightweight access points, Cisco 2000 Series or 4100 Series Wireless LAN Controllers, the Cisco WCS
with location services and the Cisco 2700 Series Wireless Location Appliance.
Features of the solution:The Cisco Distributed WLAN Solution and the Cisco Centralized WLAN Solution support similar
features and benefits through robust product capabilities. Both solutions provide management
centralization with control in the infrastructure. The primary difference between the two solutions is the
implementation and deployment of access point control and management.
The following enterprise-class WLAN features and capabilities are supported by these solutions as
applicable:
SecurityA fundamental best practice of wireless LAN security is the ability to secure and
control the RF environment. Cisco leads the industry in delivering enterprise-class RF security and
WLAN security policy monitoring. Cisco wireless security features include:
Controlled access to the WLAN via numerous authentication and encryption policies, including
802.11i, Wi-Fi Protected Access (WPA), WPA2, and mobile VPNs
WLAN Intrusion Protection System (IPS) that detects and mitigates rogue access points,
unassociated client devices, and ad-hoc networks, and provides customizable RF attack signatures to
protect against common wireless threats
Simplified WLAN management and operations support that demystifies RF and removes the
complexity of managing the RF environment.
Real-time RF scanning, monitoring, and control integrated directly into the WLAN infrastructure
delivering a self-configuring, self-optimizing, and self-healing wireless network.
The industrys first location solution that simultaneously tracks thousands of devices from
directly within the WLAN infrastructure using Ciscos patent-pending RF fingerprinting technology
Enhanced troubleshooting and diagnostic tools for proactive performance and fault
including graphical heat maps for easy analysis
monitoring,
Centralized policy engines that enable system-level security and QoS policies to be easily
configured and enforced
Quality of service (QoS) for voice and delay-sensitive applications, including over the air
bandwidth contracts
High-capacity, versatile deployments in office locations or rugged environments, with support for
a broad range of operating temperatures
Self-healing WLANs for high availability, including coverage hole detection and correction
MobilityEnd users need uninterrupted network access when roaming across access points
(within and between subnets). Ciscos WLAN solution delivers the following:
Follow-me VPNs, which enable clients to maintain VPN tunnels when roaming
Proactive Key Caching (PKC) or Cisco Centralized Key Management (CKM), helping to ensure
fast, scalable roaming in 802.11i environments
Context transfer of security and QoS policies, allowing users identities to follow them as
they roam
ScalabilityA wireless network must scale to meet current and future business requirements.
Cisco provides:
Support for WLAN deployment in the campus, branch offices, remote sites, and outdoor locations
Support for deployment of several, hundreds, or thousands of central or remotely located access
points
IntegrationEnd-to-end wired and wireless network integration minimizes the total cost of
ownership. Cisco minimizes the total cost of ownership for WLANs by supporting:
An integrated wireless and wired infrastructure, delivering a single point of control for all WLAN
traffic
Extension of rich, intelligent Cisco infrastructure device features to wireless traffic such as QoS
and management policies
Infrastructure integration via a standardized Cisco IOS Software command-line interface (CLI)
Support for several types of authentication, authorization, and accounting (AAA) servers
Advanced WLAN security and network protectionAn integrated wireless LAN IPS protects the
network from security breaches and unsecured WLAN connections that put the entire network at risk.
Customizable attack signature files can be used to rapidly detect and contain common RF-related
attacks, such as Netstumbler, FakeAP, and void11.
Wired and wireless rogue access point and client containment to maintain network security and
prevent unauthorized users from accessing enterprise resources
Integrated wired and wireless networksCisco is uniquely positioned to integrate wired and
wireless networks for cohesive, robust enterprise-wide networking capabilities.
The same policies that have evolved for an enterprises wireline security (NAC, firewall),
management (event correlation, VLANs, policy control), and QoS (802.1p, bandwidth management) can
now be extended to the wireless world.
Mobility for the enterpriseMobility becomes an intrinsic component of the enterprise, with
Cisco helping IT managers to easily and securely deploy mission-critical WLANs that complement
investments in the existing networking infrastructure.
Context transfer enables identity specific information to follow users as they roam between Layer
2 or Layer 3 domains.
QoS and Wi-Fi Multimedia support for voice over IP (VoIP)
Wireless Control System
Cisco Wireless Control System (WCS) is the industry leading platform for wireless
LAN planning, configuration, and management. Cisco WCS provides a powerful
foundation that allows KAHRAMAA to design, control, and monitor
