Costs of Wireless WAN
The WAN Set Free: Agility, Resilience & Cost Considerations in Wireless WAN
Three forces are coming together to fundamentally transform the WAN. First is the ability to easily leverage broadband Internet via software-defined WAN (SD-WAN) technologies. Second is the emergence of high-bandwidth wireless services, including Gigabit-class LTE and 5G. Third is the changing pricing model for wireless, from pay-per-bit to fixed-rate, fixed-bandwidth services.
This white paper by Nemertes Research explores how SD-WAN technologies that provide seamless load-balancing and traffic routing can provide a next-generation WAN that incorporates wireless WAN (WWAN) connectivity in one of four modes:
- Initial connectivity providing instant-on connectivity to new branches
- Failover connectivity seamlessly picking up if wired connections fail
- Primary connectivity or always-on but only to handle bursts above wired capacity
- WWAN-only e.g. for pop-up branches or those distant from wired options
