5G in mmWave bands – good enough to render fiber obsolete?

 

There is an abundance of spectrum in the millimeter
Wave bands, but offering “unlimited bandwidth” in 5G still
requires expensive backhaul (and fiber)

The mobile industry has set very aggressive targets for 5G such as: 1-10Gbps delivered connection speed (not theoretical maximum), and 1000x bandwidth per unit area (see my previous article). What will make this possible is the ability to use spectrum in the millimeter wave bands (30-300 GHz), and […]

5G reality check – who wants to pay for 1 millisecond latency?

Pointing toward the future (Ericsson CEO, MWC Barcelona)

 

Bold targets, but is the industry
promising more than it can deliver?

The mobile industry’s vision documents for 5G mobile are promising fantastic leaps in performance over current networks (links below). But as 5G evolves over the coming 10 to 15 years, it will most likely be a repeat of the pattern seen in 3G and 4G mobile.

The first step in the […]

Embedded SIMs will take mobility to the next level

SIM Cards, soon to become an outdated technology

 
 

MNOs, fear not. Embedded SIMs will open up new markets and use cases, not destroy the operators

 

Traditional SIM technology has been around for nearly 25 years and the operators view them as a critical control point for customer ownership. Due to the risk of losing the M2M market to competing unlicensed LPWAN technologies (and pressure from strong handset vendors), MNOs […]

Post Snowden ripples – users going anonymous on the Net

 

The Snowden leak is a game changer. User angst over privacy and anonymity is at an all time high. 61% of US net users want to do more to protect their privacy.

 

It takes time for consumers and market players to absorb the full impact of game-changing events such as the Snowden leak. When the news broke in June of last year, the first Pew poll showed […]

Xperia Arc’s low light camera – will Sony(Ericsson) ever come to their senses about the Mpixel race?

Xperia arc

I don’t usually pay much attention to Sony Ericsson’s products but last week I saw a billboard in the subway stating that the Xperia Arc sported a camera with excellent low light capabilities. A quick google search revealed that SE is pushing the 8 Mpix low light camera as a major selling point. The low light capabilities come from Sony’s new sensor technology Exmor R.

It looks like SE’s […]

New UI/UX after Apple’s iPhone/iPad

Sometimes I get the impression that the industry believes the iPhone and iPad represent the pinnacle of human technology. Even though the majority of the market attention is on these form factors, several new UI technologies are already out of the labs. These technologies have the potential to disrupt the traditional smartphone/tablet market and might pave the way for new types of products.

Here are a few examples that point toward […]

What will happen to webOS after HP’s exit?

Update: According to The Next Web’s internal sources, HP is NOT going to sell or shut webOS down, just the underperforming hardware device division. HP communicated this in a clumsy way which gave the erroneous impression that webOS was dead or for sale. HP’s plan seems to be to license webOS to hardware partners. But if HP is going to sell their PC division, they can’t force the […]

WebOS’s new life as HP’s Trojan horse

webOS from HP/Palm on different screens

The Google/Motorola deal suddenly makes it relevant to take a closer look at the other OS platforms on the market. Most industry observers in the mobile space have already written off HP/Palm’s webOS as a dead platform. From a smartphone perspective, this is obvious at first sight. With two percent of smartphone users in their only market (US), negligible global sales, and a thin […]

How cross-platform tools can end the OS wars

This article has previously been published on VisionMobile’s blog.

 
The Android vs. iOS vs. Windows Phone platform battle has been the talk of the industry for the last year. But the market share battle between handset platforms might not be as critical for the industry as many believe.

A popular view in the industry is that the market is inevitably moving towards an Apple-Google duopoly. Apple’s app store has […]

The HTML5 hype – time for a reality check

The hype created by the promise of HTML5 has almost reached fever pitch during the last quarter. With HTML5/CSS3 it will be possible to run most types of applications directly in the “browser” and the need to install apps that execute native code will be a thing of the past. HTML5 can run from a cache in your smartphone/tablet/PC even if you are offline and the app can access the […]

Amazing ways to interface with your computer

Eventually the mouse and keyboard will be replaced as our primary way of interfacing with the digital world by something else. Voice input, and pen/finger based touch screens are the most well-known candidates but there are several other more advanced technologies being developed.

One example is I-Tech’s Virtual Keyboard (introduced in 2005) with a red laser that projects a keyboard on to any surface. You type and the sensors will detect […]

Flawed design in Sony Ericsson’s Satio camera phone

Satio smartphone with camera

All mobile phone vendors hope to repeat the success of Apple with a new Jesus phone. Sony Ericsson’s candidate is Satio (previous working name Idou) and they are positioning the integrated 12 megapixel camera as the “killer app” that will lift Satio above the other smartphone competitors when it hits the shelves this fall.

Unfortunately, I think they have made a serious design mistake in their choice of […]

The telcos’ dilemma: LTE or HSPA+ (deja vu 2002)

Will financially burdened telco operators postpone investments in the 4G technology LTE? This has been an ongoing topic within the industry for over a year. LTE provides the operators with higher capacity, spectral efficiency, and data rates but requires heavy investments in new infrastructure. The alternative is to settle for the 3G upgrade HSPA or to upgrade the installed networks with HSPA+ (“turbo 3G”). An investment in HSPA+ is both […]

Why did the vision for public W-Lan networks fail?

Today it is obvious that business models that are based on public Wlan networks will never live up to the hype from 2002-2004. The dramatic price pressure for mobile data via 3G/HSPA undermined the market for Wlan operators. The choice is easy between spotty Wlan coverage and comprehensive geographical service with a 3G dongle.

Other players within the industry can learn several important lessons from the relative failure of this business […]

Welcome to the English version of my blog

The WordPress plug-in for multi-language blogs I have been waiting for (WPML) is now reasonably stable and I can launch the blog in English. Sidebars, tagline and widgets are not yet adaptable for dual language versions but that will hopefully be fixed soon. To begin with, I will translate most of my Swedish posts and that will take some time. For future blog posts, my plan is to simultaneously publish […]
