Small Cells and the Predictability Challenge

By | December 14, 2012

Anyone closely involved with small cells base station could not have failed to notice the contentious debate on backhaul capacity requirements. On the one hand, vendors of millimeter wave equipment advocate the need to support peak capacity figures, while on the other hand, vendors of other types of backhaul solution including point-to-multipoint systems point that… Read More »

What’s the Deal with MSS Spectrum?

By | November 29, 2012

Mobile Satellite Services (MSS) spectrum is bustling with activity. With so many failed satellite service companies, it is no surprise that spectrum earmarked for such services be converted, or allowed to co-exist with profitable mobile services. Here, I like to summarize some of the developments surrounding MSS spectrum.

In Focus: US Spectrum Service Allocation

By | November 19, 2012

Ever wondered how spectrum is allocated to different services? I recently came across the pie chart below showing allocation of spectrum between 108 and 6000 MHz for a “typical” European country. I decided to do a similar exercise for US spectrum allocation. But first I like to give a brief overview of how spectrum is… Read More »

Summary of Select Spectrum Auction Results

By | November 6, 2012

Below is a summary of spectrum auctions completed this year that I did not report on.  Some of these auctions are particularly interesting. For example, the 2.3 GHz band auction in Hong Kong follows a failed attempt to auction this band in early 2009. At that time, the hype around WiMAX was subsiding as interest in LTE… Read More »

In Focus: Interference in the 2.4 GHz ISM Band

By | October 23, 2012

In my previous blog entry, I set out to answer the question of how much WiFi is deployed. Here, I like to focus on the question of interference.  Unfortunately, I think there are fewer studies that characterize WiFi usage and interference than there ought to be. I will show here a few of the results… Read More »

How Much WiFi Is Out There?

By | October 9, 2012

The success of WiFi is nothing short of outstanding. Who would have thought that wireless network operators would adopt the technology and deploy WiFi access nodes in their tens of thousands to off-load their wide area networks? But with more carrier WiFi being rolled out in addition to your typical enterprise and personal access nodes,… Read More »

In Focus: The Where, Who and What of the 3.65 GHz Band

By | September 29, 2012

The FCC adopted the rules for the 3.65 – 3.7 GHz band in May 2007, a good nine years after it first proposed to allocate the band to non-Government fixed services on a primary basis. This timeline coincided with parallel development of WiMAX where equipment based on the fixed version of the standard (IEEE 802.16d)… Read More »

Exclusive versus Shared Spectrum: Scarcity to Abundance?

By | August 26, 2012

In a bold move, the President’s Council of Advisors on Science and Technology (PCAST) recommended for federal spectrum to be shared between federal and private sector. This radical departure from “business as usual” when it comes to spectrum management holds much promise for accelerating innovation in the wireless industry.

Would The Slicing and Dicing of Mobile Traffic Bound Growth?

By | August 20, 2012

In a mid-year update on global mobile data traffic growth, ABI forecasts that the volume will exceed 107 exabytes in 2017, which is eight times the expected volume in 2012. According to ABI research analyst Aapo Markkanen “2015 will be the last year when the traffic volume will grow by more than 50% annually. And… Read More »

Under the Microscope: AT&T’s Nextwave Acquisition

By | August 13, 2012

In the most recent deal, AT&T filed to acquire Nextwave’s WCS (Wireless Communication Services) and AWS (Advanced Wireless Services) assets for $650 million. The bulk of this deal is about the WCS band, so what is this deal about and what does AT&T get for the money?

Setting a Value on the US 2.3 GHz WCS Band

By | August 5, 2012

When the WCS band was first auctioned off in 1997, 30 MHz of spectrum in 2.3 GHz was sold for $14.8 million. At the time, it seems reasonable to pay that much for spectrum with stringent regulatory requirements on RF out of band emissions to protect the adjacent satellite DARS band (Digital Audio Radio Service).… Read More »

It’s the Signaling Stupid!

By | July 22, 2012

If you have been following the wireless industry, you for sure would have heard of the capacity crunch and exploding demand for mobile traffic data services. Hardly any presentation by a vendor, analyst, and even operator starts without a graph of future traffic trends. But quietly, another problem has been brewing; one that has received… Read More »

Aligning Mobile Services with Spectrum Properties: Information Showers

By | July 14, 2012

One essence of wireless communication does not change: the reliance on spectrum availability. The frequency spectrum is endowed with different features and characteristics that make trade-offs a necessity. One trade-off is that between data rate and mobility. The lower part of the frequency spectrum which is most amenable for mobile services due to economic reasons… Read More »

New Frontiers in Wireless Communications: Extremely High Frequency Communications.

By | July 1, 2012

The success of personal wireless communications may have been inevitable: communications is an essential tenant of human social structure. Coupled with the proliferation of wireless communication has been a drive to open up new bands of frequency spectrum. The most recent example is the millimeter wave band around 60 GHz which was assigned for unlicensed… Read More »
