Not as Easy as Ethernet
Some analysts refer to the new WLAN systems as wireless switches, but that's a misleading term that conjures up too close a comparison to Ethernet switches. Wireless LANs are significantly more complex than Ethernet LANs, at both the physical and data link layers. So while Ethernet switch designers don't have to think twice about moving bits reliably down copper and fiber cables, WLAN infrastructure designers must devote an extraordinary amount of attention to the matter.
Much of the industry is focused on the differences among wireless infrastructure designs. But there's nothing inherently better about thin wireless access points, which provide a limited set of functions, than about smart access points from Cisco, Enterasys and Proxim. For a short time, some suggested that thin access points could be made--and sold--for less than smart access points, but in today's commodity chip market, that's just not the case.
The key difference isn't in the access-point design but in the way the access points are coordinated to deliver an integrated set of wireless connectivity, mobility and security services across a multibuilding network infrastructure. This coordination isn't easy to achieve--a fact that's just dawning on both the start-ups and the established players. Not surprisingly, the ambitious product-delivery schedules established by some new system vendors have slipped.
If you plan to deploy a wireless LAN in the coming year, you can invest in smart access point technology that's mature but limited or in next-generation technology that's not yet perfected. If you opt for a newer, "state of the art" system, just be sure the vendor is willing to install a pilot system at your site so you can verify both its capabilities and its shortcomings. Buying blind is a mistake you don't want to make.
Subsea cable alternatives can provide a level of comfort for those concerned about disruptions. Realistically, they will continue to play a small, but critical role in the short term.
Maintaining existing network infrastructures often incurs huge technical debt before newer technologies are adopted over time.
Amid ongoing regional uncertainties, telecom infrastructure in the Middle East has expand to include terrestrial low-latency network infrastructure, which offers resilience and agility in navigating political complexities without relying solely on undersea networks.
