The rise in remote workforces and overseas branch locations has forced the phaseout of traditional WAN architecture. Legacy networks are not designed for the cloud. The network approach preceding SD-WAN was MPLS, which does not meet the cloud networking requirement and is not pocket-friendly. Here, SD-WAN pitches in with significantly lower cost and quality of service enhancements. With substantially lower cost and ease of configuration, SD-WAN is slowly replacing MPLS.

SD-WAN cannot do this alone; it is essential to choose wireless connectivity to deliver comprehensive benefits—to organisations involved in small offices catering to remote branches or mobile workforce. In SD-WAN, costs are less, and configuration is simple. Though SD-WAN is not the only solution available for organisations with a remote workforce, wireless connections can also be deployed in tandem for superior benefits. Companies with distributed branches in the suburbs, rural areas, or small offices outside the metropolitan region can find SD-WAN with wireless a notable option for flexibility and performance. With wireless, you can quickly scale up and down your business. Some of the benefits of SD-WAN and the wireless combination are as follows:

• Flexibility and reach: In modern business, network connectivity is not restricted to the office. Access is the key for everyone, from frontline workers to road warriors to seafarers. Wireless with SD-WAN delivers quick deployment, higher range, and speed even at remote locations, making mobility possible. With this perfect combination, your business is sure to overcome all limitations.
• Resilience: Though MPLS has ruled the network world for years, it cannot compete with the growing demands of cloud applications and security. You need multiple wireless and wired connections like 4G LTE, 5G and broadband to avert these limitations. You can manage multiple devices and access various technologies simultaneously with multiple connections. You can access diversity when wireless technology is in; even if one wireless connection goes down, the other can keep your business up and running. Traffic can be moved automatically without the end user knowing it. This improves network resilience as wired connections can share the same physical path or underground ducting even in independent lines.
• Network management: SD-WAN’s uniqueness is its facilitation of network management. Multiple network connections help with redundancy, load balancing, and traffic segmentation. Wireless connections help administrators gain access to out-of-band management abilities. They bring complete visibility into network performance to ensure downtime is reduced and productivity is improved. SD-WAN ensures quick network management using combined wireless technology, giving you a complete independent route into your network.
• Bandwidth augmentation: Bandwidth requirements vary depending on the use cases, where low-speed fixed lines become impractical and higher-bandwidth fixed lines become commercially unviable. In such situations, businesses can offload traffic to connections, providing performance and availability at an affordable price.
