Wireless Network Plan
The Infrastructure deployment scenario is recommended for Apex Designs’ Conference Center.
Deployment Scenario Reasoning
The Infrastructure deployment scenario will allow for wireless access points (WAPs) to be connected to the existing wired network allowing employees with wireless devices the ability to access the company’s network. This is a commonly used method of enhancing an existing wired network while adding the benefit of mobility to employees and is a cost-effective way to upgrade to a wireless local area network (WLAN). On-the-go employees can potentially improve job productivity while in the Conference Center by having the ability to wirelessly access company printers, file servers, and Internet and/or Intranet without the need to plug into the company network.
This section will detail the hardware component recommended for use in the wireless upgrade for the Apex Designs’ Conference Center. Each item specified was thoroughly researched for the best performance, ability to work with legacy equipment, cost, and investment longevity. Along with each component detailed are hyperlinks for reference and/or more information.
Component Name: Cisco Aironet 1252 Access Point
Justification for using component: The Cisco Aironet 1250 series APs are the first Wi-Fi CERTIFIED 802.11n draft 2.0 AP. It has also earned the Intel Connect with Centrino certification. As a thin client, the Cisco Aironet 1250 AP uses “Multiple In, Multiple Out” (MIMO) technology which uses wireless signal reflections to increase the device’s range and expand the coverage area to reduce dead spots; additionally, this WAP is UL 2043 Plenum rated for installation above suspended ceilings and supports Power over Ethernet (PoE) connectivity (or external DC power) allowing it to be installed in places that are not near electrical outlets. Other features found on the Cisco Aironet 1250 Series AP product sheet include: •
Backward compatibility with 802.11a/b/g devices.
Data rate support of up to 300 Mbps per Radio and 600 Mbps per AP. •
Gigabit Ethernet transmission ability and additional powerful platform tools required for 802.11n and wireless technologies of the future. •
External RP-TNC Antenna Connectors for both 2.4 and 5-GHz Radios. •
Investment protection - radio modules are upgradeable with the new technologies that evolve eliminating the expense of new AP installations. •
Built-in RF management capabilities help improve system performance and provide automated self-healing to make-up for RF dead zone and/or AP failures. •
Security using Cisco Unified IDS/IPS to monitor the RF environment for unauthorized wireless activity, rogue APs, and RF denial of service attacks. •
Management Frame Protection will encrypt transmissions and alert network administrators if an AP detects spoofed frames from malicious attackers. o
Rough cost estimate: $795
Part number: AIR-LAP1252AG-A-K9
How many units required: Four (4)
Component Name: Catalyst 3560 24-port 10/100 PoE + 2 SFP Standard Image Switch o
Justification for using component: This switch is fully compatible with the Aironet 1252 and will support PoE for each dual radio module AP eliminating the need for a separate power injector or additional drops of cabling; additionally, the Catalyst 3560 is a manageable switch capable of simplifying the wireless network by becoming the single point of administration. Other features found on the Cisco Catalyst 3560 Ethernet Switch data sheet are: •
Easy to use and deploy with use of a Web browser and Cisco Express Setup. •
Superior manageability including already made templates for routing, access and virtual LAN (VLAN) deployment scenarios. •
Provides PoE support with automatic endpoint discovery without user configuration. •
Excellent redundancy for fault backup to ensure overall network reliability and stability. •
High-performance IP routing with multiple routing...
