As we become more dependent on data and cloud-based file sharing, having an immediate connection with business resources is crucial for customers and employees alike. Recently, broadband technology has made significant breakthroughs in reaching 5G broadband speeds. 5G speeds are lightning fast and will help software-defined wide area networks (SD-WANs) transform corporate networking operations at branches, offices and work sites.

The Role of SD-WAN and Corporate Networking Over the Next Few Years

A company’s corporate network is composed of all the connected computers, mobile devices, servers and hardware that receive and transmit critical data between users within a secure framework. The more information a business shares, the higher the broadband capacity, availability and dependability needed to safely respond and enable data storage and transmission.

Imagine the network necessary to control everything from asset tracking and supply chain management to utilities and surveillance from an Android or iPhone without compromising speed, data or signal strength. In the coming years, expect more remote monitoring business solutions, as more than 30 billion devices will connect through Internet of Things (IoT) technology by 2020 — and only six billion of those devices being smartphones.

Though it is a daunting challenge, IoT frameworks operating on robust SD-WAN networks will be more capable of making reliable connections and enabling speeds necessary for multiple business operations.


Technology grows fast, and it’s important to understand networking so that corporations can adapt to the coming changes. 5G is now a reality, and the more equipped a network is to transfer large data sets at a breakneck 5+ gigabits per second (Gbps) speeds, the better.

Competing multiprotocol label switching (MPLS) networks can struggle to scale up bandwidth and resilience to meet the demands of the increasingly popular high-bandwidth office applications. More businesses than ever rely on an SD-WAN network not only to relay spreadsheets and customer data but also to stream video, messaging and social media information in their daily operations.

Cellular-based SD-WAN benefits include:

  • Instant availability for new branches or pop-up sites
  • Enhanced visibility, scalability, performance and control
  • More connectivity options across geographic boundaries than underground networks
  • No bandwidth penalties
  • No necessary changes to network infrastructure
  • Upgradability through nearly instant aggregation of additional cellular links
  • Cost effectiveness
  • Enhanced security and network-wide encryption

With 5.5 Gbps download and 2.7 Gbps upload speeds available over the 5G network right now, it is entirely possible to envision SD-WAN solutions based on a blend of cellular data products either replacing or being added to MPLS across corporate data centers, branch offices, store branches and other corporate sites.

The 5G Path to a Faster Future

Recent innovations in network transport technology have made it possible to reach speeds over 5 Gbps. 5G technology works with existing SD-WAN frameworks and helps users in a myriad of ways. Imagine streaming a high-definition video presentation in real time, securely uploading a decade’s worth of financial data in minutes to a new client or monitor and controlling smart grid solutions for several worksites at once. The speed is here. Expect competition to focus on faster solutions for bolstering productivity.

5G also enhances employee experience during video and audio teleconferencing. Along with higher speeds supporting more realistic video resolutions and frame rates, 5G networks bring ever-improving latency times.  As 5G networks mature with the conclusion of core upgrades, latency performance will drop into the single-digit millisecond (ms) mark. Human conversational interaction requires less than 6 ms to feel natural and present — and that is entirely within the realm of upcoming specs for these networks delivered to the branches and offices leveraging SD-WAN over 5G.

Modules, such as Telit’s LM960 Gigabit Class LET Cat 18 data card with speeds of up to 1.2 Gbps, and FN980m 5G sub-6 GHz and millimeter wave (mmWave) data card delivering data rates up to 5.5 Gbps, are designed for easy integration and installation within existing SD-WAN corporate networks. This technology will be critical in helping businesses extend their 5G capabilities and stay competitive while keeping deployment costs to a minimum.
