Over a year ago, SK Telecom invested in SigFox in a round that raised €100 m from a consortium of investors that included Telefonica and NTT Docomo. This week, SKT announces that it will build a LoRa network at a cost of more than $84 m over two years. In the meantime, SKT is working with Ericsson to evaluate the… Read More »
MWC16 was a great venue to check the pulse of developments in IoT connectivity. We summarized part of our observations which we shared and published (link). It caused many follow ups by colleagues and friends who voiced a wide range of opinions that I thought some further color would be useful. To start, the main challenge in IoT is… Read More »
The wide-area IoT connectivity battle which has been brewing for a couple of years is heating up. Early last month at CES, Ericsson announced the release of “the first complete cellular low-power wide-area (LPWA) solution” to AT&T. At the same time, the Wi-Fi Alliance branded 802.11ah as Wi-Fi HaLow targeting applications in smart home, connected car, digital healthcare, industrial, retail, agriculture, and… Read More »
Standardization of 5G is split into two phases. The first phase, which is scheduled for 2H2018, will focus on a subset of use cases and features. The second phase which is scheduled for December 2019, will meet ITU2020 requirements for 5G technology. Phase 1 will also focus on sub 6 GHz bands although carriers in Asia are pushing… Read More »
IoT use case are fragmented with different requirements. To match these requirements, a number of IoT connectivity solutions are available including wide-area low-power (LPWA), cellular wireless technologies (EGPRS, UMTS, LTE of different varieties), and short range technologies adapted to cover wide areas through mesh networking (ZigBee, WirelessHART, etc.) or extension of point-to-multipoint technologies (e.g. 802.11ah/HaLow). Each of these… Read More »
Is 5G an evolution or a revolution? In an earlier article I said 5G is an evolutionary stage. Many disagreed: 5G is a revolutionary technology. But this is all a matter of perspective. The evolution vs. revolution debate has largely focused on the air interface, or the ‘subscriber interface’: everyone wants to have fast wide-bandwidth connectivity. Naturally, it is the… Read More »
Hundreds of millions of dollars have poured into the low-power wide-area (LPWA) IoT connectivity market over the past 2 years alone to kick start a fledgeling ecosystem of companies across a wide range of products and services. In the process of due diligence and research in this market that we undertook at Xona Partners, we find the following key… Read More »
The 5G picture is getting clearer by the day. While there is still a lot of fuzziness that will take take time to crystallize the broad outline for 5G is now more clear. Below, is a summary of some of our findings on 5G. Needless to say, 5G developments will have significant ramifications especially as the capital expenses… Read More »
Mobile network operators love to compete on performance (a few forget they need to make money!). Throughput takes most attention as does coverage. Other parameters like latency has been gaining popularity as data consumption increases. Not many MNOs talk about the sites they operate, except in financial statements and annual reports. I wanted to see if the cell site count has… Read More »
The wireless industry is rapidly entering a phase of reduced spending on infrastructure. This is evident from the many operator discussions on their future plans and is inline with analysts forecast of peaking infrastructure spending at $23 billion this year. Deployments in in the US, Japan and Korea have taken their course, but still some recently acquired bands… Read More »
There has never been as much uncertainty about spectrum for a new generation of mobile service technology as there exists today for 5G. GSM was set in the 800 / 900 MHz band and 3G was set in the 2.1 GHz band. Vendors aligned their products with the target bands. There was clear focus and purpose. Then came… Read More »
In past articles [1, 2], I stressed that Cloud RAN is a disruptive technology. There are a few reasons for this, but I think that most critical reason is that Cloud RAN breaks open a pricing structure that’s been in use ever since the wireless industry was created. The current pricing model for base stations is based on a… Read More »
Reading some of the literature about LTE-U (and LAA) leads you to believe that its deployment is a foregone conclusion: operators love it; vendors support it, and products will be available within months. But operators lack the sales channel into the enterprise where LTE-U is envisioned to be deployed and provide most value. While LTE-U may find its… Read More »
You don’t need to be a wireless carrier to operate an LPWA network and provide IoT connectivity services to hundreds of thousands of devices. LPWA technologies operate in unlicensed spectrum which opens a wide door to anyone to play in the IoT connectivity space, including of course mobile network operators (MNOs). But is LPWA for MNOs? Or more… Read More »
Microgeneration allows one to generate electricity for own use, typically using renewable resources such as wind or solar energy. Excess energy can be sold to the power company. The arrangement helps in evening out the variability in energy consumption. It reduces the peak load requirements for the main grid while energy generated during non-peak hours can be diverted… Read More »
