The Internet of Things (IoT) is changing everything with regard to the modern LAN, as Frost & Sullivan reported in an infographic. As the infographic shows, as enterprises embrace IoT, top challenges surface:
The Traditional LAN
The traditional LAN connection endpoints use 4-pair category five or better copper wire. It is limited in distance to about 330 feet or 100 meters. Before the advent of the IP phone, a main concern was how much bandwidth could a PC access on the LAN. LANs started off at 10 Mb, then evolve to 100 Mb, and finally to 1 Gb. The primary design goals were for supporting connected PCs, printers, and scanners. The traditional LAN was not designed for a large quantity of endpoints, nor for bandwidth requirements like the IP phone. IP phones do not require a lot of bandwidth but require quality of service and consistent bandwidth for their operation. This is quite different than the bursty traffic normally encountered with PCs. The traditional LAN has to be reconsidered and redesigned to support the wide range of new devices encountered with IoT and the workplace of the future.
”The Modern LAN: Rethinking Network Design for the Modern Age,” is a useful white paper authored by Frost & Sullivan’s industry experts. The document provides consultants, resellers, and modern enterprises with a revolutionary set of new best practices to accommodate the impact of the Internet of Things on the local area network.
John Croce and I discussed the six LAN design principles as outlined in the Frost & Sullivan paper. These principles will overcome traditional barriers to IP devices and the IoT, and establish a network capable of supporting IoT objectives today and into the future. The following is a digest of our conversation.
The Modern LAN
The LAN endpoint population has grown in quantity and diversity. LANs must now support IoT, IP phones, video, security systems, and TV, as well as more connections. The number of connections has or will exceed the PC/workstation population in most enterprises. The newer endpoints will be further away than can be supported by traditional 4-pair data quality cable. It may even be connected using coaxial cable. Smarter endpoints need a smarter LAN.

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.
