Is LTE-U DOA?

LTE-U vs Wi-FiReading 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 way into the handset fairly rapidly, its path into the Wi-Fi access nodes will be long and arduous as that ecosystem is not particularly friendly to LTE-U (Cisco for example), while the channels of the small cell vendors, such as Huawei and Ericsson, into the enterprise are less established.  Read more of this post

Time for a Comprehensive Strategy for License-Exempt Spectrum

Spectrum ConnectivityCalls for regulators to release more unlicensed spectrum for Wi-Fi are getting louder: the 2.4 GHz band is heavily used and the 5 GHz band suffers from many restrictions that limit its applicability. LTE’s entry into unlicensed spectrum is further amplifying these calls and adding an acute sense of urgency.

But what is required is more than additional unlicensed spectrum. There needs to be a comprehensive strategy not only for additional unlicensed spectrum, but also for ensuring that regulations are harmonized to the extent possible between regions and are aligned with socio-economic needs. This is because we reached a point where additional spectrum means greater divergence between regions and increased market fragmentation, a similar scenario to the current state of the 5 GHz band.

Microcapacity: Unbinding Wireless Capacity Through Trading Exchanges

bandwidth exchangeMicrogeneration 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 to where it is most needed. There is no reason why wireless cannot work in a similar way. I call this “mcirocapacity”: individuals, businesses and communities can generate their own wireless capacity and sell the excess capacity to the wireless carriers. The concept is not novel and elements of it have already been developed. What is lacking is the impetus to put it into practice. Simply put, the time is yet to be right. Read more of this post

Are MVNOs the Next OTTs?

MVNOThe wireless market in Canada is on the cusp of changes due to new regulations that open the market for a new breed of MVNO services. Full MVNOs are now possible: they will be able to have their own mobile network codes (MNCs) and provision their own IMSI numbers. Full MVNOs own their core network including all subscriber related entities (HLR or HSS, etc.) while relying on wholesale service provider for the radio access network only. This makes these MVNOs independent at least from a retail perspective from the underlying host wireless carrier. MVNOs will be able to make arrangements with multiple wireless carriers and negotiate their own roaming arrangements with other national and international carriers. However, the regulator stopped short of mandating MVNO models, leaving it in the hands of incumbent MNOs. So the question remains: will these new rules stimulate the market and allow greater vitality in what is now a dull MVNO landscape?  Read more of this post

LTE Flavors in Unlicensed Spectrum

LTE-U LAA

Guest post by Faris Alfarhan*

The unprecedented increase in demand for high-speed broadband requires a bundle of solutions to satisfy the demanded capacity. Unlicensed spectrum is increasingly considered by cellular operators, internet service providers, and businesses as part of solution set. Unlicensed spectrum cannot match the quality of licensed spectrum, as the interference profile is much more stochastic. However, unlicensed spectrum offers a complimentary solution to licensed carriers for operators, and an opportunity to cable companies and internet service providers – who typically don’t own any licensed spectrum – to deploy wireless networks and hotspots.

Taking Wi-Fi to Sub 1 GHz

IoT internet things connectivityThe 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 not limited to among these standards, but also extends to include proprietary protocols which makes developments in this space particularly interesting to watch in the next few years.

How to Het Net!?

How to Het NetThere 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 that does not attract the attention but for the few engineers and managers directly tasked with making Het Nets work. Or maybe in our world today sound bites are all that matter and nobody has the time to ‘look under the hood.’ Whatever the case, the how of Het Nets is what matter most in the wireless networking ecosystem. Simply put, get it wrong and your are doomed. How Het Nets will happen is pivotal with high implications end-to-end because it is fundamentally based on competing technologies which while it may coexist in some limited circumstances, economics demands a winner to achieve scale.
