Cisco EHWIC-4G-LTE-A | 4G LTE Advanced WAN Module

Cisco EHWIC-4G-LTE-A Specifications & Features in Pakistan

The Cisco EHWIC-4G-LTE-A is an enterprise-class Enhanced High-Speed WAN Interface Card designed to provide high-speed 4G LTE wireless connectivity. Specifically optimized for North American carrier bands, this module is widely utilized in Pakistan by multinational firms and local enterprises requiring a high-speed, reliable backup or primary WAN link. Integrated directly into Cisco ISR G2 routers, it offers a seamless transition between wired and wireless networks, ensuring business continuity for mission-critical applications.

Key Performance Highlights

• High-Speed Mobile Broadband: Supports the latest 3GPP Release 8 LTE standards, delivering peak download speeds of up to 100 Mbps and upload speeds of up to 50 Mbps.

• Carrier Specific Optimization: Built for LTE Band 17 (700 MHz) and Band 4 (AWS 1700/2100 MHz). While primarily used for specific deployments, its backward compatibility with HSPA+ and UMTS makes it versatile for various 3G/4G transition scenarios.

• Seamless Failover: When used with Cisco ISR G2 routers, the module provides automated WAN failover. If the primary leased line or fiber link fails, the router instantly switches traffic to the LTE network, maintaining active VPN sessions and VoIP calls.

• Integrated Wireless Management: Unlike external USB modems, the EHWIC is managed directly via Cisco IOS Software. This gives network administrators full visibility, advanced QoS controls, and robust security features like hardware-accelerated encryption.

• Dual Antenna Support: Features two SMA antenna ports for MIMO (Multiple Input, Multiple Output) technology, which significantly improves signal reception and data throughput in areas with challenging cellular coverage.

Business Advantages for the Pakistan Market

1. Reliable Disaster Recovery

For businesses in industrial zones like SITE or Sundar, where physical cable cuts are a common occurrence, the EHWIC-4G-LTE-A provides a critical safety net. It ensures that Point-of-Sale (POS) systems and cloud applications remain online even when the primary ISP is down.

2. Rapid Deployment for Remote Sites

In remote or temporary locations—such as construction sites or seasonal branch offices—where waiting for a wired installation is not feasible, this 4G module allows for instant WAN connectivity. As long as cellular coverage is available, your branch can be operational in minutes.

3. Secure Enterprise Connectivity

Because the module runs within the Cisco IOS environment, it supports advanced security protocols including IPsec VPNs, Firewalling, and Intrusion Prevention Systems (IPS). This makes it far more secure than using consumer-grade 4G routers for corporate data.

Deployment Scenarios

• Banking & ATM Connectivity: Providing a secure, high-speed backup link for ATM machines to ensure 24/7 transaction availability.

• Retail & Branch Offices: Acting as a primary or secondary WAN link for high-traffic retail outlets requiring constant cloud synchronization.

• Telemedicine & Video: Providing the necessary bandwidth and low latency for interactive video and high-definition telepresence sessions.

• IoT & Remote Monitoring: Connecting remote industrial equipment to central SCADA systems for real-time telemetry and data logging.

Related FAQs

1. Can I use the EHWIC-4G-LTE-A with any mobile network in Pakistan?

The EHWIC-4G-LTE-A is specifically tuned for North American bands (Band 17/4). In Pakistan, while it may work on certain 3G/4G frequencies, for the best compatibility with local carriers, the Global version (LTE-G) is usually recommended.

2. Does this card require a separate power supply?

No. The module draws power directly from the EHWIC slot of the Cisco ISR G2 router, simplifying the internal rack power management and reducing cable clutter.

3. What is the benefit of the two antenna ports?

The two ports allow for MIMO (Multiple Input, Multiple Output) connectivity. Using two antennas helps the module combine signals from different paths to increase data speed and reliability, especially in indoor environments where signals reflect off walls.

4. How do I monitor the signal strength of the LTE link?

Signal strength (RSSI) and other cellular metrics can be monitored directly through the Cisco IOS CLI using the show controller cellular command or via graphical management tools.

5. What software version is required to support this module?

The EHWIC-4G-LTE-A typically requires Cisco IOS Release 15.2(4)M or later. It is also recommended to keep the modem firmware updated to ensure maximum stability and performance on modern LTE networks.
