4G LTE is a strong WAN access contender (and not just because of the bandwidth!)

As cellular services reach broadband speeds, they begin to gradually enter corporate WAN access networks. For example, the router's extensive 3G services and the availability of 3G line cards have caused some corporate sites to plug in 3G as a landline backup. With the widespread popularity of 4G LTE services, wireless WANs will undoubtedly become more popular in these and other applications. It's not just because of speed. Of course, 4G LTE is about 20 times faster than 3G. About 100 times faster than the T1 circuit. Impressive, but perhaps even more interesting is that all 4G services are IP-based, including voice. 3G networks are still running circuit-switched voice services and IP data services, and intelligent Layer 3 network services cannot be applied to them. 4G has changed that. Now you can integrate voice and data over a wireless WAN like you used to do last-mile links over wired IP: With WAN optimization, traffic management and QoS, all these good things allow you to adjust and control traffic. Wireless deployment is fast; establishing a wireless primary or backup WAN connection within the same business day is feasible. We are well aware of this approach commensurate with the overall slogan of "Agile IT." Also, wireless links are cheaper, but similar services are now available for wired. In the United States, 4G LTE speeds are up to about 50Mbps. These are theoretical top speeds; the operator cuts the spectrum into segments and cuts them into small pieces, and you will have to ask them. But this is really respectable.
