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 »

MWC 2012: Larger Devices, Smaller Cells!

By | March 3, 2012

Just back home from MWC’12… What a show this year… Over 67,000 attendees and some 1500 exhibitors, and some student protests in the mix… It was the biggest to date and a good finale for the Fira before moving next year to a new nearby location. For those in the mobile infrastructure space, long gone… Read More »

700 MHz Spectrum Auction in Canada: To Set Aside or not to Set Aside?!

By | January 28, 2012

The rules for the upcoming 700 MHz spectrum auction are set to be announced soon after parliament returns from its two months winter recess on January 30th. In the lead up, we’ve had an amazing debate raging between the incumbents (Rogers, Bell and Telus) who back an open auction and the new entrants (Wind, Mobilicity,… Read More »

Analysis of the 2.6 GHz Spectrum Auction in Belgium

By | November 29, 2011

The 2.6 GHz spectrum auction in Belgium closed yesterday after it netted a total of €77.8 million for a total of 155 MHz. Although the media reported the outcome as being low, I think the price is representative for this band at 4.6 euro cents per MHz-PoP. This is more so the case as the license is valid for 15 years while in other countries the licenses are for period of up to 20 years.

The Italian 4G Spectrum Auction: An Analysis

By | October 17, 2011

After 22 days and 469 rounds, the 4G frequency spectrum auction in Italy closed on September 29th netting the government over €3.9 billion. By all measures, the auction was a great success with prices exceeding the reserve prices in a country that has not been far from the epicenter of financial turbulence in the Eurozone.

What Path Loss Models Have to Do with Financial Models?

By | September 15, 2011

I was recently asked by a business associate how to estimate the capital costs of an LTE network. Inevitably our discussion led to estimating the number of sites required to cover a market. Designing to meet coverage requirements along with its complement, capacity requirements, form the basis for estimating the size, and consequently cost, of the radio access network. This is something that differentiates the financial modeling service provided by Telesystem Innovations. So I like to expand in this post on a few general principles related to path loss models which play a critical part is determining cell size.

Korean Spectrum Pricing – An Analysis

By | September 6, 2011

Last week, Korea’s largest mobile network operator SK Telecom successfully acquired 20 MHz of spectrum in the 1.8 GHz band for 995 billion won ($924 million). SK Telecom, which plans to use this band for LTE, beat out KT Corp which dropped out of the race as the price exceeded twice the reserve level of 445.5 billion won set by the KCC (Korea Communications Commission). KT Corp settled for a 10 MHz license in 800 MHz for the minimum bidding price of 261 billion won ($242 million).

The End of Wireless?!

By | August 31, 2011

The numbers for mid-2011 are in and the big picture for mobile network operators is clear: overall ARPUs continue to decline led by declining voice service revenue. Data service revenue continues to grow, but not at a sufficient rate to compensate for the decline in voice revenue. In fact, data services which on average constitutes a about a third of ARPU fail to stabilize ARPU and hold off the erosion.

Dichotomy of Access and Backhaul Capacity Planning

By | July 20, 2011

I have listened to a few webinars recently by some of the major microwave backhaul vendors, all with the message that microwave has enough capacity to support required LTE data rates. It is evident that network operators have been pushing these vendors for higher data rates. Microwave after all cannot compete with fiber on capacity and MNOs (Mobile Network Operator) have been laying lots of fiber in anticipation of LTE network roll out.
