WiMAX vs. LTE

Mobile WiMAX, with the release of 2×2 MIMO chips in 2008, gives WiMAX a lead of two or so years on its major competitor -- the 3GPP's LTE. However, 3G cellphones using 3GPP UMTS technologies, extended to higher speeds with HSPA, is widely used in handsets in many countries. In North America, 3GPP2 CDMA2000 and EV-DO are widely used, but these are likely to be replaced over time by LTE and to some extent WiMAX. more

America Will Not Win the Global Race to 5G

Several weeks ago, the White House published a document asserting that "America Will Win the Global Race to 5G." The White House should get over it. This is not about America winning any global race to 5G, but the world working together on fundamentally different, complex, new communication networks and services. There are four important points, however. more

About That Second, Third and Fourth Wireless "Attachment"

There is some good news about the decision by Verizon Wireless to offer shared monthly data plans. But there could be a lot more if the FCC applied its Carterfone policy. That policy gave consumers the power to decide what and how many devices to attach to a network connection. If Carterfone applied, consumers could use multiple devices to access a network subscription, albeit perhaps not at the same time. more

LTE Insufficient from the Start, Boingo IPO Propitious

The trouble with planning way ahead is that the world changes before you execute. The major wireless carriers have been planning their 4th generation LTE (Long Term Evolution) rollouts for a long time -- that's how they do things. Now, even as Verizon Wireless is doing an aggressive rollout of LTE, it's becoming clear that LTE networks will not be able to slake the data thirst of a world full of smart phones and tablets. Whoops. more

A Closer Look at Apple and Location-Tracking

There's been a lot of media attention to a report that iPhones track your movements. It's even reached the U.S. Senate. I'm underwhelmed. I think that the threat is overhyped. What is happening is that these devices create a hidden file with your location... more

IPv6 Over Satellite: Pie in the Sky?

I am writing this from the Satellite 2008 conference in Washington, D.C. As I make my way through the exhibits, I see many vendors advertising IP capabilities in their hardware products or network services. But when asked about IPv6 support, the common reply is a not so believable "it is on our roadmap" followed by a somewhat vague delivery date. Although IPv6 development has been slow across the board, it appears to be moving even more slowly in the satellite world... more

WiMAX vs. WiFi

In fact WiFi (technically standard 802.11) and WiMAX (802.16) don't compete for broadband users or applications today. That's partly because WiFi is widely deployed and WiMAX is still largely an unfulfilled promise and partly because the two protocols were designed for very different situations. However, if WiMAX is eventually widely deployed, there will be competition between them as last mile technologies. Some people describe the difference between WiFi and WiMAX as analogous to the difference between a cordless phone and a mobile phone... more

Trump Orders Cyberattacks by US Companies

It is supremely ironic. A rogue national leader with the stroke of a pen, dictates that its companies will expose a foreign company's end users to cyberattacks. This is the net effect of denying security patches or operating system updates pursuant to Trump's order. In the US Great Rogue Leader's bizarro world, this is the very behavior that he claims makes his actions necessary. In fact, this Trump malware attack is worse because of the mass exposure to exploits. more

Electronically Steerable, Flat-Panel Antennas for Satellite and Terrestrial Connectivity

What will the cost and capability of these antennas be in ten or twenty years? What would be the applications and implications of ubiquitous wireless networks? You might have some short-term guesses, like smart cities, but farther out it's science fiction -- Gaia, the Noosphere, 1984? ... Three companies, OneWeb, SpaceX and Telesat, plan to provide global, low-latency broadband Internet service using constellations of low-Earth orbit (LEO) satellites. more

5G Security Transparency

There is considerable rhetoric propagated today about 5G security. Some of the more blatant assertions border on xenophobia with vague assertions that the 5G vendors from some countries cannot be trusted and wholesale government banning is required. Existing treaty obligations are being summarily abrogated in favour of bilateral trade bullying. These are practices that the late President George H.W. Bush sought to eliminate a quarter century ago through intergovernmental organization initiatives... more

Hidden in Plain Sight: FCC Chairman Pai's Strategy to Consolidate the U.S. Wireless Marketplace

While couched in noble terms of promoting competition, innovation and freedom, the FCC soon will combine two initiatives that will enhance the likelihood that Sprint and T-Mobile will stop operating as separate companies within 18 months. In the same manner at the regulatory approval of airline mergers, the FCC will make all sorts of conclusions sorely lacking empirical evidence and common sense. more

Broadband Carrier Quandary: Exploit Bandwidth Scarcity, or Reduce It?

Comcast enhanced the value position of its broadband subscriptions by increasing the monthly data allowance to 1 Terrabyte (1000 Gigabytes). See Comcast Announcement. As an independent, unsponsored researcher, I can say "Thank You Comcast" without adverse consequences and only a bit of irony. This company does much to displease, but an expanded data allowance offers a winning proposition. more

Mobiles Moving Into Fixed Networks

There are often confused reports in the media about mobile and fixed broadband, with arguments that one could replace the other. Yet the reality is that they coexist and complement each other - perhaps even more so since one cannot manage without the other. Increasingly, devices such as smartphones, tablets and smart TVs are at the end of fixed lines, with a wireless (WiFi) connection between the fixed line and the device. more

Spectrum Key to Broadband Utility

The explosion in mobile communications in the developing world has created social and economic changes that have exceeded all expectations and predictions -- even those made as recently as five years ago. There are still countries lagging behind, but now is the time to move on to the next stage -- and that means broadband. Already the developed world is showing an enormous appetite for mobile broadband, so the demand is most certainly there. The rapid development of low cost Smartphone, projected to approach $50 soon... more

Why Wireless Broadband Is No Alternative to FttH

The mainly politically-driven debate - FttH versus wireless broadband - is spreading uninformed messages and half-truths in the market. And confusing messages from mobile operators are also blurring the picture. All well-informed people confirm that this is a nonsensical debate -- both infrastructures will coexist with, and supplement, each other. more
