5G Myths and Realities

Myths about 5G

5G is millimeter wave technology.

5G is a hot spot system.

5G needs new 5G spectra.

5G is IMT-2020 defined by ITU.

5G replaces 4G.

For 5G, all things need something new.

5G needs significant investment.

Myths about 5G





5G replaces 4G.



Partially “Yes” and millimeter wave is

a key for 5G.

However, it’s not all.

Myths about 5G





5G replaces 4G.



5G provides Higher data speed and Higher capacity.

Broader spectrum bandwidth

Higher frequency spectrum

Larger propagation loss

Shorter coverage

5G is a Hotspot system for complementary use.

Existing spectrum New spectrum

Frequency

e.g. 3-10GHz e.g. 10-30GHz e.g. > 30GHz

A wrong story I don’t like

Let’s tackle the challenge of achieving wide coverage

as cellular systems even with higher spectrum.

Myths about 5G





5G replaces 4G.



•Spectra are independent of technology generations.

(ITU identifies IMT bands, not 5G bands.)

•5G doesn’t necessarily need new bands, while new

spectrum is key to extremely high performance. 5G uses new bands as well as existing bands with combinations

from the beginning (and eventually by refarming).

Existing bands for 3G

• We don’t need to cry over the LTE spectrum fragmentation.

• Let’s use the existing bands for LTE and

encourage enhancement of multi-band support in devices.

Amendments to Release 99 will continue in 3GPP. NTT DoCoMo will also comply with these future changes, and will update network/handsets accordingly.

DoCoMo will provide global roaming services with operators in Europe, etc. (whose 3G services start in 2002). Connectivity testing to take place prior to offering global roaming service.

Updated in Spring 2002

DOCOMO’s network handles both versions of Rel. 99 protocols, so that DOCOMO can continue to provide 3G services for initial users and global services for new users.
