Site-to-site Virtual Private Networks (VPNs)
Secure networking using the public Internet

A virtual private network (VPN) is a network that uses a public telecommunication infrastructure, such as the Internet, to provide remote offices or individual users with secure access to their organization's network. A virtual private network can be contrasted with an expensive system of owned or leased lines that can only be used by one organization. The goal of a VPN is to provide the organization with the same capabilities, but at a much lower cost.

A site-to-site VPN connects two or more geographically separated offices using your existing Internet connections. A VPN-capable device is installed at each location, creating a secure encrypted “tunnel” to transmit private data across the public Internet. 

DTS provides installation and support for Sonicwall based VPN devices.

POINT TO POINT WIRELESS SOLUTIONS

DTS recommends Cisco Aironet Wireless Access Points

As WLAN deployments expand, security, scalability, reliability, ease of deployment, and management become increasingly important. Cisco provides a comprehensive line of access points that deliver enterprise-class features for business-ready wireless LANs.

EXECUTIVE SUMMARY
Access points are critical elements of the Cisco® Unified Wireless Network. Cisco single- and dual-band access points are designed for offices and similar environments, challenging radio frequency (RF) environments, and the outdoors. The devices are available in two versions, those configured for lightweight operation in conjunction with Cisco wireless LAN controllers and the Wireless Control System (WCS) as well as those configured for autonomous operation in conjunction with the CiscoWorks Wireless LAN Solution Engine (WLSE). Autonomous access points, along with the WLSE, deliver a core set of features and may be field-upgraded to lightweight operation and an advanced feature set.
To make the best choices for their particular applications, customers need to understand the features and benefits of the different Cisco Aironet® access points. This solution overview details the capabilities of each of the devices in the Cisco Aironet wireless access point family.
MANAGEMENT PARADIGM
As wireless LANs become increasingly mission-critical and evolve in terms of scale and capabilities, the way the wireless deployment is managed must evolve as well. As each customer and each deployment is unique, Cisco provides differing feature sets and differing management paradigms to address these customer-specific requirements.
Cisco provides a core feature set that includes autonomous access points and the CiscoWorks WLSE management appliance. The core feature set provides a base set of capabilities that are required for enterprise deployments. Core features include secure connectivity through support for 802.11i/Wi-Fi Protected Access 2 (WPA2), fast and secure Layer 2 roaming, and interfaces to a variety of third-party applications and products. Most Cisco access points are available in versions designed for autonomous operation. These devices may be upgraded in the field to lightweight mode, thereby providing customers with a smooth path from core to advanced features.
The Cisco advanced wireless LAN feature set is delivered by lightweight access points, wireless LAN controllers and the Wireless Control System (WCS) management application. The advanced feature set represents the most comprehensive set of capabilities in the industry including guest access, wireless intrusion detection, scalable Layer 3 mobility, and available location services. Most Cisco Aironet access points are available in versions designed for lightweight operation.
DEPLOYMENT ENVIRONMENTS
Wireless LANs are becoming commonplace in numerous environments, including offices, schools, factories, and warehouses-and even the outdoors. At the same time, the wireless industry is evolving from lower-capacity, single-band devices to high-capacity dual-band solutions. The Cisco Aironet family of access points meets these various application requirements, providing:
• Single- and dual-band access points
• Devices designed for indoor and outdoor deployments
• A consistent hardware feature set and predictable RF performance for deployment across the enterprise
As WLAN deployment expands into more applications and installation scenarios, a diverse line of access points is required to meet the associated capacity, coverage, and environmental requirements. Cisco provides access points with either single 802.11g radios for up to 54 Mbps of capacity or dual-radio access points supporting both 802.11g and 802.11a for up to 108 Mbps of combined network capacity. The Cisco product line includes access points designed for offices and similar facilities such as hospitals and retail environments, challenging RF environments like factories and warehouses, and the outdoors. These devices can be installed on desktops, on walls, on ceilings, above ceilings, and on top of poles.
While application requirements may vary, Cisco understands that all enterprise customers require uncompromised network security, scalable manageability, and an evolving set of network services. That''s why all Cisco Aironet access points, regardless of form factor and capacity and regardless of whether they operate in lightweight or autonomous mode, support the Cisco Unified Wireless Network, a framework for wired and wireless integration that delivers the security, manageability, and services that enterprises have come to expect from Cisco on both wired and wireless networks.
SOLUTION
Addressing Feature Requirements
As wireless LAN usage has evolved from basic transport for largely transactional applications, so have the feature expectations of wireless LAN users and administrators. This evolution has evolved, however, on a segment-by-segment, customer-by-customer basis. It is critical for Cisco to provide differing feature sets to best fit differing customer requirements. Given that customer requirements can evolve during the lifetime of a wireless LAN deployment, it is also necessary to provide a means of smoothly upgrading this feature set for the installed base of products with minimal disruption to network operations.
Cisco''s advanced wireless LAN feature set offers the features required for most enterprise deployments. Some deployments may not yet require these advanced capabilities. To address these evolving requirements, customers can select either access points preconfigured for lightweight operation and the advanced feature sets, or can upgrade autonomous access points in the field to lightweight operation. With Cisco, customers can choose the feature set that is right for them at the time that it is right for them. Table 1 provides a summary of the operational capabilities of various Cisco Aironet access points.
Table 1. Operational Capabilities of Cisco Aironet Access Points

Addressing Capacity Requirements
In just a few years, WLANs have evolved from proprietary systems with sub-Mbps capabilities to standardized offerings operating at as much as a combined data rate of 108 Mbps. These high data rates are available in both the 2.4 GHz band with 802.11g technology and the 5 GHz band with 802.11a technology. 802.11g offers backward compatibility with 802.11b devices, but is limited to three non-overlapping channels in the 2.4 GHz band. 802.11a provides no backward compatibility but supports as many as 23 channels (depending upon local regulations). To provide both backward compatibility and high capacity, WLAN client vendors are migrating to dual-band 802.11a/g-capable client devices. In 2006, 802.11a/g devices are expected to become the predominant type for embedded and aftermarket client adapters designed for laptops, desktops, and even PDAs. Over time, these dual-band capabilities are expected to extend to almost every WLAN client device, including application-specific devices like voice handsets, barcode scanners, and radio frequency identification (RFID) scanners.
Deploying an infrastructure that takes full advantage of the expanding capabilities of the client base makes sense if capacity is currently an issue or is expected to become an issue during the useful life of the infrastructure devices. Given the rapid expansion of wireless-enabled devices, increasing capacity requirements are likely to apply to most WLAN installations. For this majority of applications, access points that support both 802.11a and 802.11g represent a better long-term value, particularly given their low price premium relative to single-band devices. For the few applications that are not expected to present capacity issues in the near term, customers can choose single-radio access points. Table 2 summarizes which Cisco access points support 802.11a, 802.11b, and 802.11g.
Table 2. Cisco Aironet Access Point Support for 802.11a/b/g

* With a hardware upgrade module, the Cisco Aironet 1200 Series access point may be field-upgraded to support 802.11a.

Cisco Aironet 1230AG Series Access Point
The Cisco Aironet 1230AG Series is a preconfigured dual-band version of the 1200 Series, providing support for 802.11a and 802.11g. This first-generation dual-band device does not, however, provide the same performance and support for 802.3af PoE as does the 1240AG Series.
Cisco Aironet 1000 Series IEEE 802.11a/b/g Lightweight Access Point Model 1020 and 1030
Delivers 802.11a/b/g wireless LAN access with zero-touch configuration and management. It provides diversity antenna connectors for 2.4 GHz operation and a single non-diversity connector for the 5 GHz band. The Cisco Aironet 1020 is available only as a lightweight access point and does not support autonomous operation. The device does not provide the same extended operating temperature range as the Cisco Aironet 1230AG Series and 1240AG Series, and requires additional mounting hardware. It does not provide the same level of security and tamper resistance as that is provided by 1230AG Series and 1240AG Series. As the Cisco Aironet 1020 is limited to lightweight operation, customers with hybrid lightweight and autonomous deployments cannot standardize on a single hardware platform.
Cisco Aironet 1030 Lightweight Access Point is a version of the 1020 with software capabilities that allow the device to be deployed remotely from a wireless LAN controller. This unique capability makes the 1030 ideal for small branch office deployments where local placement of a wireless LAN controller is impractical or uneconomical.
Outdoor Access Points/Bridges
Cisco Aironet 1300 Series IEEE 802.11g Wireless Outdoor Access Point/Bridge
Provides autonomous access point, wireless bridge, and workgroup bridge capabilities with enhanced WLAN security.
