WPA/WPA2 Enterprise Wi-Fi Networks

Network Configuration

ÂMake sure port 443 is open on the firewall. If your company uses Outlook Web Access, port 443 is most likely already open.

ÂVerify that a server certificate is installed on the Exchange frontend server and enable Require Basic SSL for the Exchange ActiveSync virtual directory.

ÂOn the Microsoft Internet Security and Acceleration (ISA) Server, verify that a server certificate is installed and update the public DNS to properly resolve incoming connections.

ÂMake sure the DNS for your network returns a single, externally-routable address to the Exchange ActiveSync server for both intranet and Internet clients. This is required so the device can use the same IP address for communicating with the server when both types of connections are active.

ÂOn the ISA Server, create a web listener as well as an Exchange web client access publishing rule. This is a necessary step in enabling Exchange ActiveSync. See Microsoft’s documentation for details.

ÂFor all firewalls and network appliances, set the idle session timeout to 30 minutes. Refer to Microsoft Exchange documentation for alternative heartbeat and timeout intervals.

Exchange Account Setup

ÂEnable Exchange ActiveSync for specific users or groups using the Active Directory service. These are enabled by default for all mobile devices at the organizational level in Exchange Server 2003 and Exchange Server 2007. For Exchange Server 2007, see Recipient Configuration in the Exchange Management Console.

ÂConfigure mobile features, policies, and device security settings using the Exchange System Manager. For Exchange Server 2007, this is done in the Exchange Management Console.

ÂDownload and install the Microsoft Exchange ActiveSync Mobile Administration Web Tool, which is necessary to initiate a remote wipe. For Exchange Server 2007, remote wipe can also be initiated using Outlook Web Access.

Support for WPA Enterprise and WPA2 Enterprise ensures that corporate wireless networks are securely accessed on iPhone and iPod touch. WPA/WPA2 Enterprise uses 128-bit encryption, a proven block-based encryption method that provides a high level of assurance that corporate data remains protected.

With support for 802.1X authentication, iPhone and iPod touch can be integrated into a broad range of RADIUS server environments. 802.1X wireless authentication methods are supported and include EAP-TLS, EAP-TTLS, EAP-FAST, PEAPv0, PEAPv1 and LEAP.

Chapter 1 Deploying iPhone and iPod touch

iPod and iPod Touch specifications

The Apple iPod, first released in 2001, revolutionized the way we listen to music. This portable media player, with its sleek design and user-friendly interface, quickly garnered a dedicated following. The original iPod featured a mechanical scroll wheel and a minimalist aesthetic, allowing users to carry their music libraries wherever they went. It was a game changer in the digital music landscape, encouraging both casual listeners and audiophiles to embrace the concept of portability.

As technology evolved, so did the iPod. The introduction of the iPod Mini in 2004 marked a transition to a smaller, more compact design. In 2005, Apple launched the iPod Nano, which showcased an even slimmer profile, vibrant color displays, and flash storage for improved resistance to shocks. The most significant evolution came with the introduction of the iPod Touch in 2007, which transformed the iPod into a more multifaceted device.

The iPod Touch brought a touchscreen interface, resembling the iPhone. It allowed users to access not only their music but also apps, games, and web browsing capabilities. The device was powered by Apple's iOS, featuring a robust App Store that offered thousands of applications, from productivity tools to entertainment options. With Wi-Fi connectivity, the iPod Touch enabled users to stream music and videos, browse the internet, and utilize apps without being tethered to a computer.

In terms of audio quality, iPods have consistently featured high-performance DACs and audio processors, capable of delivering excellent sound reproduction. With support for various audio formats, including AAC, MP3, and Apple Lossless, users could enjoy their music without compromise. The integration of iTunes provided a seamless ecosystem for purchasing, organizing, and syncing music.

Throughout its iterations, the design of the iPod Touch has also evolved. The latest generations sport a sleek aluminum casing, Retina displays, and advanced camera systems. Features such as FaceTime, iMessage, and Apple Music integration have positioned the iPod Touch as a versatile device, appealing not only to music lovers but to a broader audience seeking a portable multimedia experience.

Ultimately, while the rise of smartphones may have overshadowed the iPod, its impact on the music industry and digital media consumption remains undeniable. The legacy of the iPod and iPod Touch is characterized by innovation, portability, and a continuous quest to enhance how we experience music and entertainment in our daily lives.
