3. Linksys Maximum Performance Dual-Band N900 Router, E4200v2  The Linksys E4200 v2 is a true dual-band router, meaning it has two separate access points--one for the 2.4GHz band and the other for the 5GHz band--that can work simultaneously. It's also the first from Cisco to offer the 450Mbps (or 3-by-3) configuration on both bands.  In addition to the networks for the two bands, the E4200 v2 offers another wireless network on the 2.4GHz band for guests. Guest networking is great for when you want to share the Internet with others without giving them access to your local resources, such as files or printers. The E4200 v2's guest networking feature allows up to 50 clients.  The E4200 has simple and straightforward support for network storage, including features such as sharing the content of a USB external hard drive (formatted using either NTFS or FAT32), with user account restriction. By default the admin account has full access and can create more user accounts. It also has a built-in UPnP media server with which you can stream digital content to other UPnP-compliant devices, such as set-top boxes, network media players, and game consoles.

4. NETGEAR N900 Wireless Dual Band Gigabit Router - WNDR4500 - WNDR4500-100NAS  The WNDR4500 is the first dual 450Mbps router from Netgear that offers the 450Mbps ceiling wireless speed on both the 5GHz and the 2.4GHz bands. This is the new three-stream standard (aka 3x3) that's getting more popular in high-end wireless routerS.  The N900 is capable of simultaneously broadcasting Wireless-N signals in both the 2.4GHz and the 5GHz bands. It's also able to broadcast two more guest wireless networks, one for each band  The second big feature of the N900 is its two USB ports that can be used to host external hard drives and printers.. Once a drive is plugged in, its contents will be immediately shared across the network, with everybody having full access to it. The router supports the SMB protocol, meaning any computer in the network can browse for the shares using a network browser such as Windows Explorer or Finder. This is a rather simple yet effective way to quickly share content.  The router also allows users to stream digital content stored on the hard drive to DNLA-compliant network media players, such as the Xbox or PlayStation. This feature automatically scans the attached external hard drive for digital content, making it available to devices within the network. The router can also automatically scan for new content when new files are added or repeatedly over a period time.

6. Model For Enterprise Wireless Gateway Cisco 881G Integrated Services Router with 3G Modem

7.  Integrated 3G WWAN broadband: With the 3G WWAN modem integrated into the router, you gain the benefit of simplified installation and management. In addition, the Cisco 3G WWAN are tightly integrated with Cisco integrated services routers, which run the industry-leading Cisco IOS Software, giving you access to all the advanced features of Cisco IOS Software such as quality of service (QoS), intelligent network queuing, and robust security.  Short installation time: Businesses sometimes wait for weeks or months to get data circuits installed at new locations. For temporary or seasonal sites, wireless data services allow instant connectivity anywhere there is cellular coverage, and rapid deployment allows you to quickly set up networks with WAN connectivity.  Network resiliency through WAN diversity: WAN connectivity is crucial to the functioning of your business, and any downtime means a loss of productivity and lost opportunity. Staying connected and operational during a network outage can be vital. A wireless connection for backup to a remote site provides protection against line outages and an additional level of redundancy because the 3G WWAN infrastructure is often served by separate facilities, providing redundancy for the entire local loop.  Reduced cost: The emerging 3G WWAN cellular data service plans are competitively priced with existing wireline services (ISDN, DSL, and cable). 3G WWAN solutions also allow you to consolidate your service providers across large geographical areas instead of having service contracts with multiple service providers.  Portability: Cisco 881G with 3G WWAN can be easily relocate wherever coverage is available.

8.  Performance: With increasing data usage and the proliferation of web-based applications at remote sites, there is an increasing need for high-speed (broadband) data connections to run mission-critical applications at these sites. 3G WWAN services promise low-latency links at speeds approaching T1 connections, allowing you to send and receive more mission-critical data across the WAN in backup scenarios.  VPN to secure remote sites With up to 20 VPN tunnels, the Cisco 881G Integrated Services Router is ideal for small branch offices and teleworkers who need to be connected to larger enterprise networks as well as small businesses, for either voice or data applications. These Cisco routers help extend corporate networks to secure remote sites while giving users access to the same applications found in a corporate office.  Multiple Features for Businesses In addition to 3G wireless WAN, the Cisco 881G offers additional WAN options such as xDSL and Fast Ethernet WAN interface, and a 4-port 10/100 Fast Ethernet managed switch with VLAN support. The Cisco 881G provides the performance required for concurrent services, including firewall, intrusion prevention, content filtering, and encryption for VPNs; and quality-of-service (QoS) features for optimising voice and video applications. In addition, Cisco Configuration Professional is a web-based configuration tool that simplifies setup and deployment. Centralized management capabilities give network managers visibility and control of the network configurations at the remote site.
