There have been many attempts over the past two decades to compete with fixed line copper, coax and fiber installations with Wireless Broadband Fixed Access. Pretty much all of them have failed on a larger scale as technology over copper has evolved and fiber has been deployed in many places. But Verizon thinks Fixed Wireless … Continue reading Verizon Pushes Forward with mmWave Broadband Fixed Access
Going significantly beyond the capacity and geographic reach of current cellular LTE coverage in cities requires to bring the cells to where the people are: Inside buildings. From a technical point of view small cells could do the job, they are now small enough to be installed just about anywhere. From a practical point of … Continue reading Eduroam as a Model for Future Public Wifi Deployments
As Anandtech says ‘in a surprise move’ Intel has announced last week that they will discontinue their 60 GHz WiGig + Wifi + Bluetooth cards. As they were pretty much the only ones selling WiGig connectivity options for notebooks so far I can’t help but wonder if this move has just spelled the end for … Continue reading Intel Discontinues Their 802.11ad Notebook Cards – The End Of WiGig?
In a previous post I wrote about one mobile network operator in Germany now being on air with LTE with 65 MHz. So far, network operators have been in the comfortable position to add additional spectrum to increase their network capacity. But this game will come to an end pretty soon!
Like every year, time has flown and it is already end of December and thus time to look back at what has happened this year that has literally ‘moved’ me. This year I have three categories: Networks, Linux & General computing and Miscellaneous Other Things. Let’s start with a look back at my year in … Continue reading Things That Moved Me In 2016 – Part 1: Networks
Recently, T-Mobile US has announced that they have switched on 4×4 MIMO support in their network and first smartphones are now supporting 4 simultaneous downlink streams. Quite an interesting announcement as most antennas and base station sites currently deployed by most operators do not yet support this. So let’s have a look at what has … Continue reading From Dipole to Active Antenna Systems and 4×4 MIMO
LTE for Public Safety Services, also referred to as Private Mobile Radio (PMR) is making progress in the standards and in the first part of this series I’ve taken a first general look. Since then I thought a bit about which advantages a PMR implementation might offer over current 2G Tetra and GSM PMR implementations … Continue reading LTE-A Pro for Public Safety Services – Part 2 – Advantages over PMR in 2G
One feature some proponents are pushing for future 5G networks are ultra short reaction times for ultra critical communication, for example between cars. What I failed to understand so far in this discussion was why for car to car communication a fixed network infrastructure and a backhaul network was necessary!? After all, car to car … Continue reading 32C3 – Vehicle2Vehicle Communication with IEEE 802.11p
It's day 2 of the 32C3 in Hamburg and I'm really happy that I was able to attend in person this year. My previous tip to use a 5 GHz Wifi capable Android phone as a WiFi USB dongle for my notebook has paid out as the 2.4 GHz range is hopelessly overloaded in most … Continue reading 32C3 – Recommended Videos of Day 1
It’s become almost a tradition for me in December each year to have a look back at what happened in the previous 12 months in the telecoms industry and in my private technology endeavors that have left long lasting impression or have marked the start of something new. And so here we go again, in … Continue reading Things That Moved Me In 2015
