سيسكو NIM-4G-LTE-LA Network Interface, 4G LTE for Asia Pacific, Australia and Latam Network Interface Module
نظرة عامة على المنتج
4G LTE can provide either primary connectivity or backup communications, offering network resiliency for business continuity. With greater agility and speed to deployment than wired solutions, 4G LTE can reduce network cost, and it complements wireline public and private network access. Practical applications of 4G LTE for organizations include parallel networks, primary connection, failover, in-vehicle connectivity, network convergence, and last-mile diversity. The 4G LTE NIM with the Cisco 4000 series Integrated Services Router leads the industry in bringing enterprise grade functions such as Quality of Service (جودة الخدمة), Multi-Virtual Route Forwarding (Multi-VRF) , advanced VPN, and Unified Communications solutions over LTE.
The Cisco 4G LTE NIMs (شكل 1) provide an enterprise-class 4G multimode LTE wireless WAN (WWAN) solution. With Cisco ISRs, 4G LTE is a powerful primary WAN access solution. Businesses can now run applications such as interactive video and telepresence on a primary 4G LTE connection, which is up to 50 times faster with far lower latency than third-generation (3جي) links. These 4G modules support the latest Third-Generation Partnership Project (3جي بي بي) Release 9 LTE standards. Cisco 4G multimode LTE WWAN NIMs provide persistent, reliable LTE connectivity with fallback and transparent handoff to earlier technologies. The cards provide bandwidth to support high-definition (عالية الدقة) and peer-to-peer (P2P) video calls, providing customers with an excellent mobile broadband experience. The Cisco 4G LTE WWAN NIMs are tightly integrated with the services provided on the award-winning Cisco 4000 Series ISR devices, which deliver secure data, صوت, فيديو, and mobility services. The Cisco 4G LTE WWAN NIMs are supported on the modular Cisco 4200, 4300 و 4400 Series ISR devices.
Enterprises are looking for ways to reduce deployment time, enable comprehensive media services, increase revenue, and improve business continuity. The Cisco 4G LTE WWAN NIMs, when coupled with a service provider’s wireless data plan, provide a rapidly deployable, عرض النطاق الترددي العالي, موثوق, and secure solution for branch offices and remote sites. With 4G LTE data rates, the Cisco 4G LTE WWAN NIMs offer a primary WAN link solution capable of running comprehensive branch-office services, including voice and video services.
The Cisco LTE WWAN NIMs include the following models:
● Cisco LTE 2.0 NIM for Global (NIM-4G-LTE-GA): Multimode LTE for carriers that operate LTE on 800-MHz (band 20), 900-ميغاهيرتز (band 8), 1800-ميغاهيرتز (band 3), 2100-ميغاهيرتز (band 1), or 2600-MHz (band 7) networks; the multimode LTE Global (أوروبا, أستراليا, إلخ.) NIMs are backward-compatible with 3G Dual-Cell-high-speed packet access plus (DC-HSPA+), high-speed packet access plus (HSPA+), high-speed packet access (HSPA), Universal Mobile Telecommunications Service (UMTS), Enhanced Data GSM Environment (EDGE), and General Packet Radio Service (GPRS).
● Cisco LTE 2.0 NIM for North America (NIM-4G-LTE-NA): Multimode LTE for carriers that operate LTE on PCS 1900-MHz (band 2), 850 ميغاهيرتز (band 5), 1700- or 2100-MHz (band 4 AWS), or 700-MHz (band 17); the multimode LTE North America (AT&T, كندا) NIMs are backward-compatible with DC-HSPA+, HSPA+, HSPA, UMTS, EDGE, and GPRS
● Cisco LTE 2.0 NIM for Sprint (NIM-4G-LTE-ST) and Cisco LTE 2.0 4G NIM for Verizon (NIM-4G-LTE-VZ): Multimode LTEs for carriers that operate LTE on 700-MHz (band 13), 1700- or 2100-MHz (band 4 AWS), or extended PCS 1900-MHz (band 25); the multimode NIMs are backward-compatible with EVDO A/CDMA 1X BC0, BC1, and BC10

With enhanced data rates and improved latency, WWAN services are an ideal way to replace or supplement traditional wire-line services. 4G LTE WWAN data services offered today have theoretical limits of CAT3 100 Mbps on the downlink and 50 Mbps on the uplink. The actual data speed depends on the service provider’s network. 4G LTE WWAN data services are an alternative in areas in which broadband services are either not available or very expensive. Cisco is building on these performance milestones and adding support for wireless to our wide variety of WAN interface alternatives.
