Taking Wi-Fi to Sub 1 GHz

By | December 22, 2014

The Internet of Things (IoT) is the catalyst for a number of new standards that will reshape wireless connectivity as we know it. Examples: Bluetooth LE, LTE-MTC, Zigbee, and LPWA standards. Wi-Fi (802.11) is also being reshaped to accommodate IoT applications. These applications have different requirements which make connectivity techniques for IoT fragmented. Competition is… Read More »

AWS-3 Auction Closes on $44 Billion: Did They Cross The Bounds of The Rational?

By | December 12, 2014

It seems US wireless operators have crossed the bounds to the irrational in bidding on the AWS-3 spectrum. As I write this article, round 91 closed at over $43.74 billion for the 65 MHz of spectrum. That’s a gross average of $2.3/MHz PoP. To put this into perspective, the 90 MHz of AWS-1 spectrum in… Read More »

How to Het Net!?

By | October 27, 2014

There has been much written about why Het Nets are needed (running out of capacity) and when it will happen (licensed band small cell centric view of Het Nets). On the other hand, how Het Nets will happen is rarely discussed in the general media. Perhaps this is because this is a very technical discussion… Read More »

IoT at the Peak of the Hype Cycle

By | October 23, 2014

It’s official: The ‘Internet of Things’ (IoT) is at the peak of the hype cycle. It only took 15 years to get to this point, considering the term was first coined in 1999. But the IoT of today is quite different from initial thrust which was in commercial and industrial applications. Today, consumer applications lead… Read More »

Millimeter Wave MIMO Systems for 5G Access Networks

By | October 14, 2014

Guest post by Faris Alfarhan* Conventionally, millimeter wave (mmW) frequency bands have been either largely overlooked or treated solely as real estate for wireless backhaul and personal indoor networks. That is mainly due to higher atmospheric attenuation loss, penetration losses, and increased absorption and scattering in rainy conditions. However, recent measurements indicate good outdoor short… Read More »

It’s All Too Good To Keep Talking About The Capacity Problem

By | October 11, 2014

The capacity problem is at the heart of everything said about the wireless industry. Everybody loves to talk about this problem. To start, it is easy to give examples of exploding data consumption forecasts or quote numbers on mobile applications such as Facebook, Twitter , Instagram and many others. I suspect that the capacity problem… Read More »

Should Licensed Spectrum be Allocated to IoT Applications?

By | September 22, 2014

A mix of connectivity technologies combines to enable the Internet of Things. These technologies can be complementary or competitive in nature. Determining which fits and which does not starts with the application use case and the user requirement. For most IoT applications there is no need for broadband connectivity. Rather, what is required is a… Read More »

The IoT Value Chain: Where’s the Value?

By | September 1, 2014

$19 Trillion is a lot of money. That’s the value Cisco expect the Internet of Things (IoT) market will generate over the next 10 years. Compare with annual world GDP of 75 Trillion, IoT will make for about 2%. Not bad. In terms of devices, the talk is for 50 billion connected devices in 2020,… Read More »

Defining the Innovation Band and Shared Spectrum Access

By | July 12, 2014

Spectrum sharing rules for the 3.5 GHz band in the US are beginning to take shape. While there are still some important aspects to define, the broad lines have been drawn for the Citizens Broadband Radio Service (CBRS). The process of fine-tuning the rules will continue following the April Further Notice of Proposed Rulemaking (FNPRM)… Read More »

Raising the Stakes in 3.5 GHz: LTE-Advanced Achieves 1 Gbps

By | June 22, 2014

The 3 GHz frequency bands stands at the upper limit of what is considered today as viable spectrum for mobile communications. But bands 42 (3400 – 3600 MHz) and 43 (3600 – 3800 MHz) are not only the ‘last frontier’, but more importantly, they provide the widest spectrum of any other band (200 MHz). Additionally,… Read More »

Small Cells Progress Report – Challenges and Opportunities.

By | June 6, 2014

I have just released a new research report on the progress of small cell deployments in collaboration with ExelixistNet:  “Small Cell Ecosystem: Challenges and Opportunities.” The report examines mobile operators’ plans and deployment strategies of small cells and backhaul solutions along with vendor and technology preferences. The research is based on experience gathered by operators… Read More »

SON Progress Report: A Lot Still to Be Done!

By | May 19, 2014

Since the first building blocks of SON were laid down around 2008 by 3GPP and NGMN, uptake in SON deployments has been very selective by a few leading carriers for some use cases. However, universal applicability remains elusive. To say the least, the SON market is struggling – but why, and how that can be… Read More »

Further Enhanced ICIC (FeICIC)

By | May 7, 2014

Guest post by Faris Alfarhan* In an earlier post, R10-LTE enhanced inter-cell interference coordination (eICIC) techniques for heterogeneous networks were discussed, along with the concept of small cell range expansion. The purpose of cell range expansion is to offload more traffic from macro cells to small cells and hence achieve larger cell splitting gains. By… Read More »

Trends in Wireless Network Densification

By | April 28, 2014

One of the main trends in radio access network (RAN) is the bifurcation of systems that enable network densification. Today, mobile network operators have more options than ever before for the means of providing service to their subscribers. Alongside the evolution of wireless standards to provide higher spectral efficiency, vendors have unleashed a wide variety… Read More »
