Pushing the Limits of Wind Loading on Macro Sites

As the appetite for data continues to grow, wireless providers need to deploy more and more base station antennas to keep pace and deliver the required capacity. With 5G roll outs gathering momentum, we are seeing existing cell sites pushed to their loadbearing limit, but more is still needed. Due to the cost and logistical challenges, acquiring new sites is often not a practical option, meaning equipment designers need to push to extend the wind loading limits to ease the problem.

Making higher education institutions smarter with private wireless

Higher education institutions are seeking to rapidly digitalize their operations so they can better serve the changing needs of students, academic staff and researchers on their campuses. To succeed, they must evolve their wireless communications infrastructure to offer higher-performing applications and tools that will help their staff and students work more productively. Until now, their main approach has been to upgrade or replace existing Wi-Fi networks, but Wi-Fi technology is starting to show limitations in its ability to meet the increased demands of mobility, latency, throughput and total cost of ownership (TCO).

Microwave Backhaul, the conundrum that is African wireless

Despite what some wireless infrastructure suppliers would have the industry believe, Africa is a very different marketplace for wireless communications architectures to the rest of the world. Incredibly varied terrains and network topologies across the continent, coupled with extremes of temperature, and the steady but extremely protracted decommissioning of legacy 2G, and even 3G cell sites, all conspire to make wireless network installation and management in Africa an unusually complex and demanding task.

Overlay strategies for 700 MHz LTE deployments

Implementation of Long Term Evolution (LTE) at 700 MHz in North America calls for a cost-effective and rapid rollout. LTE provides wireless carriers with a common next generation (4G) platform and delivers much higher data rates. Deploying this technology in the 700MHz band allows for more efficient RF propagation and greater structural penetration. However, there are also issues with 700 MHz associated with a multitude of interference scenarios.
