Why Uplink Matters for 5G Video Calls — and How Kaelus Foghorn Antenna Delivers

As hybrid work becomes the norm and the workforce grows more mobile, video conferencing on smartphones has become essential for smooth remote communication.

Delivering high-quality video calls requires a stable uplink throughput of at least around 4 Mbps*, a challenging benchmark for many networks. Poor video call experiences commonly stem from limited uplink coverage.

The underlying challenge is that smartphones transmit signals at much lower power than radio base stations. Additionally, distance, building materials, and terrain can weaken the uplink signal further, leading to poor video call experiences.

Kaelus’s Foghorn antenna is engineered to address these challenges head-on. A key goal is to maximize B71 (600 MHz) band performance, often overlooked versus 700 and 800 MHz bands.

Featuring 8 ports—4 Low-Band and 4 Mid-Band—the Foghorn antenna delivers robust uplink and downlink coverage, optimized beam patterns, and high isolation, ideal for improving connectivity in complex urban and indoor environments.

Deploying Foghorn antennas can improve rural coverage by up to 15% and in-building coverage by up to 12% in urban/suburban areas.

With a form factor that generally requires no modifications to existing MLA’s (Master Lease Agreements), the Foghorn antenna is ideal for fast, cost-effective deployments at scale.

Combined with low-band spectrum and advanced radio technologies, the Foghorn Antenna helps operators reduce uplink gaps - delivering the reliable video conferencing experience that today’s mobile workforce demands.
