4G is not unfamiliar concept for people who are involved in the environment of mobile internet. Succeeding 3G, 4G is the fourth generation of mobile telecommunications technology. And what is the Cisco 4G-LTE 2.0?
4G-LTE (Fourth-generation Long Term Evolution) standards are defined in the 3GPP Release 8 standard. The 4G-LTE release improves mobile network speeds by 20 times or more. It also lowers latency by five-fold to compete with wired WAN connections. It is an evolution of 3G cellular technology, overseen by the Third-Generation Partnership Project (3GPP) standards body.
Now, Cisco is on Release 2.0 of its LTE products, offering…:
- Network Interface Module (NIM) cards for use with the Cisco 4000 (4400 and 4300) Series Integrated Services Routers
- Enhanced high-speed WAN interface cards (EHWICs) for use with Cisco ISR Generation 2 1900, 2900, and 3900 routers
- Cisco 819, 880, and 890 series fixed ISRs, which support 4G-LTE connections with the same options as the EHWICs
4G-LTE is not supported on the first-generation ISRs.
…There are many benefits to using 4G LTE as a fixed WAN access connection. For example, you can:
- Set up wireless WANs without waiting weeks for terrestrial links.
- Connect in-vehicle users for public safety applications.
- Create temporary links in construction sites, sporting events, trade shows, and kiosks.
- Avoid downtime caused by cable cuts by using 4G LTE for routing diversity.
- Get wired-like communication experiences using less-expensive wireless links.
There are many 4G LTE product options and configurations. How do you choose the right ones and put them together into a working solution?
First, you need a 4G LTE-capable router and a 4G LTE wireless data service plan from a mobile network provider. The Cisco partner community will help you pick the wireless router solution best suited to your business.
Flexible Options for Next-Generation Connectivity
Cisco can help you meet your business needs when migrating to a fourth-generation Long Term Evolution network.
The Cisco 4G LTE products and solutions accommodate a wide variety of situations and use cases. You can get connectivity built right into a fixed router, whether it’s in a traditional office or hardened for harsh environments. Or you can get the capability as an add-on module to routers you already have. Cisco Integrated Services Routers (ISRs) and smart grid Connected Grid Routers (CGRs) support 4G LTE connections in the branch office.
