Not too long ago, IT managers, RF engineers, system integrators, project managers, and OEMs had limited options when it came to deploying wireless networks in large warehouses and multi-floor buildings. The cellular bands were the exclusive domain of major carriers who held the licenses. To get cellular performance indoors, anyone wanting to deploy a private […]
More coverage at less cost is the holy grail of in-building wireless network design. Whether you’re deploying an LTE network or a 5G network at 28 GHz or 3.5 GHz, the whole point of going through the site survey, prediction modeling, and design effort is to determine the ideal placement of antennas and access points […]
Improved coverage and better use of available spectrum are two of the key advantages 5G offers. A properly planned and designed 5G network will support delivery of enhanced mobile broadband applications and experiences, provide more reliable connections for mission-critical communications, and enable the mass deployment of IoT devices. To capitalize on the benefits 5G offers, […]
MACHINE LEARNING IN CONTEMPORARY SCIENCE FICTION 2018 movie Annihilation is a science fiction movie about a mysterious area in the southern United States called The Shimmer. The Shimmer started to appear right around the time an identified object from outer space hits a lighthouse near the coastline. Within the Shimmer, rapid species mutation occurs, combining […]
What happens when using MIMO and Beamforming? A quick brown fox jumps over the lazy dog. This was a sentence that I heard upward of 500 times when I first started in this business as student intern for a regional mobile wireless carrier. Back then, carriers were transitioning from analog to digital mobile wireless. Aside […]
Earlier this year, Consultix, a leading vendor of portable CW test equipment, collected CW survey data at 28 GHz in an office environment, and shared the data with iBwave. We have post processed the data and used it as benchmark to compare with our default propagation model at 28 GHz, and also to calibrate the model. This blog entry summarizes our findings.
If RF Signals Were An Opera Picture yourself in an open space – a meadow if you will – on a quiet sunny day. In front of you, 30 meters away, is a full opera. They are singing the Canadian national anthem. Their singing is crisp and clear, just as it should be when you’re […]
In our most recent deep dive webinar, we took a detailed look at how we can design optimum networks for shopping mall environments. Summary: Contemporary shopping malls offer more than just shopping opportunities. Many include individual restaurants and bars, a food court, movie theater, gym, skating rink, etc. Malls nowadays serve as anchors of social […]
As of 2014, 934 stadiums worldwide have 30,000 or more seats: 228 in North America; 129 in Central and South America; 243 in Europe; 98 in Middle East and Africa; and 236 in the APAC region. The USA alone has 217 stadiums with 30,000 seats or more, and about two thirds of these are used […]
Most subway routes in core urban areas are located deep underground, where macro cellular coverage is non-existent. In big cities worldwide, hundreds of thousands of commuters depend on the subway (or Métro, MTR, MRT, U-bahn, Underground, etc.) on a daily basis. They need dedicated wireless networks to stay connected. First responders also need reliable public […]
