Why mmWave hasn't become the mainstream spectrum of 5G?
In a previous article of IPLOOK, we introduced what 5G mmWave (5G mmWave) is. Due to its wide bandwidth, abundant resources, and high frequency characteristics, 5G mmWave has significant advantages and was once considered a key frequency band for development in the early stages of 5G. However, today, although many countries and regions around the world have promoted or deployed 5G mmWave, the application of mmWave technology in the industry still faces uncertainties and challenges.
At the beginning of 2023, due to various factors, the construction progress of 5G mmWave base stations in South Korea was far behind expectations, with completion rates only ranging from 10.6% to 12.5%. In Japan, NTT DOCOMO and Rakuten Mobile experienced no growth in mmWave users, and their traffic share was relatively low. Even in the US, which began deploying 5G mmWave ahead of other countries in 2019, the availability of 5G mmWave networks is less than 1%.
Many people believe that the reason why 5G mmWave has not become the mainstream spectrum for 5G is because of its own characteristics and the unclear application demands:
Limited Range: leading to high cost
The mmWave has a small coverage radius, and the construction and operation costs for the same coverage area are high, which hinders large-scale deployment. As a result of its high frequency and large transmission loss, the mmWave has poor coverage ability, with a coverage radius of only about 150 meters for a single mmWave base station, which is only 1/5 of the coverage radius of low-frequency bands such as Sub-6. If a continuous coverage 5G mmWave network is to be built like in the 3.5GHz frequency band, the number of base stations needed would be more than twenty times greater than that of regular 5G base stations, leading to high construction costs.
Poor Penetration: resulting in poor user experience
5G mmWave has poor penetration capability and severe diffuse attenuation, resulting in poor user experience and customer dissatisfaction. There are two main reasons for this. First, the mmWave has a short wavelength (between 1-10 mm), making it poorly penetrating, as it can be blocked by leaves and water droplets. Second, the mmWave is sensitive to the surface of objects, easily causing signal energy to dissipate in multiple directions, resulting in poor signal reception at the receiving end and affecting user experience. For example, even though over 20,000 mmWave base stations have been built in Japan, customers are reluctant to pay for mmWave services due to prominent problems such as frequent signal interruptions and insufficient coverage during usage.
Lack of Groundbreaking Apps
Low-frequency mmWave has clear bandwidth advantages, but due to the lack of groundbreaking applications, its value is difficult to fully unleash in the short term. Globally, mid-to-low frequency spectrum resources are gradually becoming scarce, and more reliance is placed on spectrum re-farming and frequency coordination to solve this issue. In contrast, 5G mmWave, with its continuous and wide spectrum resources, can better achieve bandwidth capacity enhancement. However, by reason of the unclear promotion of large-scale applications such as XR and Smart Homes, and traditional video services can be satisfied with existing bandwidth, the short-term demand for mmWave is not significant.

Mein neues Telefon ist genau so dumm wie das alte. Aber auf dem Stand der Technik!
Tumblr media
Seit Jahren nutze ich (auch) ein dummes Mobiltelefon – dumm deshalb, weil es im Unterschied zu einem Smartphone auf die Funktionen Telefonieren und SMS beschränkt ist. Also ein Telefon und nicht die Internetzugriffsmaschine im Hosentaschenformat. Das hat verschiedene Gründe, nicht der unwichtigste: Ohne (vergleichsweise) großen Bildschirm und ohne Datentransfer hält der Akku auch schon mal ‘ne Woche. Und, haha, die per SMS zugesandten Phishing-Links gehen ins Leere, weil sie ja gar nicht erst geöffnet werden.
Nun habe ich in den vergangenen rund 15 Jahren diese Telefone mehrfach ersetzt, besser: ersetzen müssen (vgl. Foto oben). Im Unterschied zu Smartphones nicht etwa deshalb, weil die Software nicht mehr aktualisiert werden konnte. Nein, sie waren einfach mechanisch kaputtgenutzt, die Tasten funktionierten nicht mehr, das Gehäuse war gebrochen... Vielleicht nicht ganz so überraschend bei einem ausgesprochenen Billigartikel, der in der Regel für umgerechnet 15 bis 20 Euro zu haben ist.
(Und im Gegensatz zur Annahme, die Kathrin Passig im Techniktagebuchredaktionschat äußerte: Nein, ich kaufe solche Handys nicht ausschließlich bei afghanischen Hufschmieden. Tatsächlich habe ich mir eines aus Südafrika mitbringen lassen, weil Nokia dieses Billigmodell damals auf dem europäischen Markt schlicht nicht anbot. Ein weiteres habe ich bei einem Straßenhändler auf Bali gekauft, aber auch welche ganz normal im deutschen Elektronikhandel.)
Technisch hat sich also bei diesen Dummphones über das vergangene Jahrzehnt nix geändert. Bis jetzt. Denn mein neuestes Handy dieser Art, in der Reihe oben ganz rechts, bietet im Grunde genommen nichts anderes als seine Vorgänger. Bis auf die Funkanbindung.
Denn inzwischen ist mir ein schwer wiegendes Problem der simplen Mobiltelefone aufgefallen: Sie funktionieren im älteren technischen Mobilfunkstandard der 2. Generation (2G), nämlich Global System for Mobile Communications (GSM) Das wird zwar, heißt es bei Wikipedia, so schnell in Deutschland nicht abgeschaltet werden. Aber Lücken sind dennoch spürbar: Mitten in Berlin habe ich in Telefonaten immer wieder Aussetzer oder gestörte Gesprächsverbindungen.
Als ich mich im Zusammenhang mit dem bundesweiten Warntag vor einigen Wochen mit der Frage befasste, ob denn auch die 2G-Telefone per Cell Broadcast gewarnt werden (so wie ich das mitbekommen habe, nein), stieß ich zufällig auf die Lösung: Mein Dummphone von Nokia wird inzwischen auch in einer 4G-Variante angeboten. Zwar dann fast doppelt so teuer wie das 2G-Modell, aber mit rund 40 Euro immer noch vergleichsweise günstig.
Und das neue Telefon vermittelt ein ganz neues Telefoniererlebnis. Mit einer Sprachqualität halt wie ein Smartphone. Nur ohne das smarte. Mal schauen, wie lange das (mechanisch) durchhält.

Alright 😂 so my right ear is the bitch ear apparently, it doesn’t want to stretch. My left ear is super super easy and has sized up with no issues. My right is just gonna take a while 🤷🏼‍♀️ but my second lobe piercing on the left is a PITA to get anything in there and I had a stud that matched the other side but I lost it 🤦🏼‍♀️ I used to have my tragus pierced on the right and I kinda wanna get it redone? We’ll see on the next depression cycle 😂 excuse my ears looking kinda dirty, I get spray tans and it sticks more in certain areas, I promise I clean my ears 😂
