This 5G band n78 speed calculator shows that 5G band n78 speed depends on three things you can set above: channel width, MIMO layers and modulation. A 100 MHz n78 channel with 4×4 MIMO and 256-QAM reaches a theoretical peak of about 1,729 Mbps for downloads at a typical 74% download share, and about 2,337 Mbps if the whole channel were used for downloads.

The 5G band n78 speed calculator also compares n78, n41, n77, n28, n71 and the main 4G-refarmed bands, shows indoor penetration and range for each, and converts an NR-ARFCN channel number to a frequency. It is built for people choosing a phone, a router or a carrier.

How the 5G Band n78 Speed Calculator Works

The 5G band n78 speed calculator uses the 3GPP peak data rate method for 5G NR, so every 5G band n78 speed result is a theoretical peak. It multiplies MIMO layers, modulation bits, code rate, the number of resource blocks for your channel width and the symbol rate, then subtracts about 14 percent for overhead. For TDD bands such as n78 and n41 it multiplies by the share of time spent on downloads. New to 5G terms? Start with 5G vs 5G Ultra Wideband.

Band: choose from n78, n77, n41, n28, n71, n1, n3 or n7.
Channel width: the options change to what the band allows.
MIMO and modulation: pick 1×1, 2×2 or 4×4 and 256-QAM or 64-QAM.
ARFCN box: type a channel number to see its center frequency.

This table shows the theoretical peak download for popular configurations, together with how well each band penetrates buildings.

Band	Frequency	Width and MIMO	Peak download	Penetration
n78	3300-3800 MHz	100 MHz, 4×4	1,729 Mbps	Medium
n77	3300-4200 MHz	100 MHz, 4×4	1,729 Mbps	Medium
n41	2496-2690 MHz	100 MHz, 4×4	1,729 Mbps	Good
n28	DL 758-803 MHz	20 MHz, 2×2	227 Mbps	Excellent
n71	DL 617-652 MHz	20 MHz, 2×2	227 Mbps	Excellent
n1	DL 2110-2170 MHz	20 MHz, 2×2	227 Mbps	Good
n3	DL 1805-1880 MHz	20 MHz, 2×2	227 Mbps	Good

n41 vs n78 5G Comparison

Many people ask whether n41 or n78 is better. At the same channel width and MIMO they give the same theoretical peak speed, about 1,729 Mbps for 100 MHz and 4×4. The real difference is propagation. n41 at about 2.5 GHz penetrates walls a little better and covers more ground per tower. n78 at about 3.5 GHz has more spectrum available in many countries, so it often delivers the higher speeds. Phones with better modems pick up more bands, as covered in features of a high-performance 5G modem.

5G n78 Speed: What Changes the Number

Channel width: 100 MHz is about five times faster than 20 MHz.
MIMO layers: 4×4 doubles the speed of 2×2. Many phones use 2×2, which gives about 865 Mbps on 100 MHz n78.
Download share: TDD networks split time between uploads and downloads.
Modulation: 256-QAM is about a third faster than 64-QAM.

Low-Band 5G: n28 and n71 for Coverage

Low bands trade speed for reach. A 20 MHz n28 or n71 channel with 2×2 MIMO peaks near 227 Mbps, but the signal travels farther and passes through walls much better than 3.5 GHz. That is why carriers use 600 MHz and 700 MHz bands for rural and indoor coverage and C-band for dense cities. Not sure what the status bar labels mean?

5G NR ARFCN to Frequency Calculator

Every 5G channel has an NR-ARFCN number. Up to 3000 MHz the frequency is 0.005 times the ARFCN in MHz. From 3000 MHz to 24.25 GHz it is 3000 plus 0.015 times the difference from 600000. For example ARFCN 632628 equals 3489.42 MHz, a common n78 channel. The ARFCN box in the calculator does this for you.

5G Band N78 Speed: Where to Check Official Band Lists

Band definitions are published by the 3GPP standards group. You can browse them on the 3GPP website, and the details of each phone model on its manufacturer page. Always confirm that your phone and carrier both support the band you want.

Tips for Getting the Best 5G Speeds

Check that your phone supports your carrier band before you buy.
Stand near a window, since higher bands lose more signal through walls.
Use a router or phone with 4×4 MIMO on wide channels for the highest speeds.
Compare theoretical peaks with a real speed test to see how congested the cell is.

Why Use a 5G Band N78 Speed Calculator

Marketing numbers rarely say which band, width or MIMO setup they assume. A 5G band n78 speed calculator turns those inputs into a realistic ceiling, so you can compare plans and phones fairly and understand why one tower gives faster speeds than another.

Frequently Asked Questions

What is the peak speed of 5G band n78?

A 100 MHz n78 channel with 4×4 MIMO and 256-QAM reaches about 1,729 Mbps at a typical download share. Real speeds are usually much lower.

What is the difference between n41 and n78?

n41 sits at 2.5 GHz and n78 at 3.5 GHz. At the same channel width and MIMO they have the same theoretical peak, but n41 travels a little further and penetrates walls slightly better.

Is n28 faster than n78?

No. n28 at 700 MHz is limited to channels of 30 MHz or less, so it peaks at a few hundred Mbps, but it has far better range and indoor coverage.

How do I convert NR-ARFCN to frequency?

Between 3000 MHz and 24.25 GHz, frequency in MHz is 3000 plus 0.015 times (ARFCN minus 600000). ARFCN 632628 equals 3489.42 MHz.

Do all phones support n78?

No. Support depends on the model and region. Check your phone specification for the bands it lists.

Why are real 5G speeds lower than the calculator?

The result is a theoretical maximum. Real networks share the channel between users, use fewer MIMO layers on phones and lose speed to signal quality and distance.
