mmWave in a Glass House — Small Cell simulation💥🦾
Today we plan a mmWave small cell network in a Glass House
We were releasing the first commercial version of Rantastic this week (enjoy), and spend some time analysing white papers, dedicated to mmWave penetration and how radio works for such cases.
I hope you'll find this useful, or at least entertaining a bit (you know, with the Sheldon's definition of entertainment).
We've decided to take a Glass House and take a look at how 5G small cell would work inside.
We were using Rantastic for the simulation for sure😇
First, let's see what's so different in mmWave radio planning compare to other predictions exercises. Definitely, the difference in the band — 28GHz is quite a high band, and normally, it was used more for MW links, rather than for mobile networks.
We even need to consider Geoclimatic Factors for prediction models, plus we have a quite small level of diffraction.
Please see the diffraction diagrams 2.4GHz and 30GHz comparison.
Moreover — some companies offer 5G planning using a kind of LoS (Line-of-Sight) approach, and also umlaut reports that 95% of mmWave connections inside the cities are in LoS conditions.
Here's some Here examples (it hard not to enjoy typing Here and here in the same sentence🤩).
Some experts even call it the biggest challenge that faces millimetre wave (mmWave) 5G — transmitting the high-band signal through treated low-emissivity (low-E) glass, and DoCoMo even made a special glass, transparent for mmWave to overcome it. DoCoMo says that the prototype material can be used with frequencies higher than the millimetre-wave band (traditionally listed at 30GHz to 300GHz). This means it can be used in 6G communications that go up into the 120GHz and even the Terahertz (THz) range.
In our practice, we used a small House (actually a fitness club) and made it all inside from a normal glass.
We have used Samsung Link Cell for 5G NR SSB Power coverage simulation in mmWave.
We allocate only Glass for materials for required layers
Venue Size with located Samsung Small Cells
5G coverage for mmWave for the venue
It clearly that some areas are not covered with the mmWave
Adding two more Small Cell
Looks much better! It took a few seconds to get the calculation done!
Rantastic supports planning for 5G NR starting from just 30$ per month at the moment.
Free trial for 30 days is available.
