More and More Small Cells, But Where’s the Gain?

Small Cell StrategySmall cells are meant as a solution to address the explosive growth in mobile data services, right? Well, the answer is: it depends! They can be a solution under certain conditions, but not always. Yes, there could be situations where small cells add little if any gain. In fact, more than one operator mentioned to me little or even no gain in overall capacity increase by their small cell pilot projects. So what’s happening, and why can we run into situations where small cells don’t deliver on their promise? Continue reading

How Small Cells Are Reshaping The Wireless Landscape

Small CellsThere’s much talk about small cells these days – on industry news sites, at conferences, in corporate announcements. This is not surprising given that mobile traffic doubles every year and, according to Cisco, will grow at a compound annual growth rate (CAGR) of 78 percent from 2011 to 2016. Wireless network architecture has relied greatly on macrocells, but with the advent of the small cell era, how will small cells shape the wireless landscape? To answer, consider the following: Continue reading

My Top 10 Most Read Posts of 2012.

Frank Rayal Top Blog Posts of 2012Below is a list of my top-10 most read posts of 2012. Older posts would get more views than recent ones and I have no way of knowing the numbers of RSS subscriptions, etc. Also, I am hoping that viewed posts equals read posts, but there are no guarantees! Nevertheless, this is still of interest and I thought to share it with my readers.

Review of the Multi-Frequency Irish and Dutch Spectrum Auctions

Ireland / Netherlands Spectrum AuctionsThe Irish multi-frequency spectrum auction concluded on November 15th raising a respectable 854€ million ($1.1 billion) from four bidders on licenses for 280 MHz in the 800, 900, and 1800 MHz bands. Earlier this month, on December 14th, the Dutch multi-frequency auction of about 360 MHz netted the regulator over 3.8€ billion ($4.97 billion).

Both regulators did not report the price paid on a per-band/license basis. But on average, the Irish spectrum is priced at about 0.48 euro-cent per MHz-PoP (0.61₵), while the Dutch auction is priced at 0.63 euro-cent per MHz-PoP (0.83₵). Continue reading

Small Cells and the Predictability Challenge

Opinion: Small Cells and the Predictability ChallengeAnyone 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 the peak is rarely if ever achieved in practice. Continue reading

What’s the Deal with MSS Spectrum?

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. Continue reading

In Focus: US Spectrum Service Allocation

In Focus: US Spectrum Service AllocationEver 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 allocated. There are two organizations responsible for spectrum in the US: the National Telecommunications and Information Administration (NTIA) regulates spectrum use for federal users and the Federal Communication Commission (FCC) regulates spectrum use for non-federal users (including local and state governments). Spectrum bands can be designated for exclusive Federal users, or exclusively for non-federal users. But often, spectrum is shared between the two. Continue reading

Summary of Select Spectrum Auction Results

Spectrum AuctionsBelow 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 was gathering strength. Now, three companies won the 90 MHz band for about $61m. One of the winners told me of their plan to use the band for LTE services, although this would be TD-LTE. No indication as to when it will happen. Continue reading

In Focus: Interference in the 2.4 GHz ISM Band

WiFi/ISM Band InterferenceIn 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 and conclusions and present my own model and take on interference.

How Much WiFi Is Out There?

How much WiFi is out there?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, how much WiFi is out there? How much interference does it generate? And what does that say about the future when it comes to unlicensed band spectrum utilization? Continue reading

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

In Focus: 3.65 GHz BandThe 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) first came to market in 2005. In this post, I look at deployments in this band especially as it called for certain features to accommodate co-existence between different systems. But first, here’s a very brief overview of some of the regulatory features. Continue reading
