5G Spectrum Costs: The Value of 3.5 GHz Spectrum

Interest in the 3.5 GHz band is increasing as its set to become the global 5G spectrum band. We recently undertook a study for a new research report* of global 3.5 GHz band to uncover the impact on the 5G deployment timelines and ecosystem. One of the fundamental questions is putting figures on the value of the 3.5… Read More »

3.5 GHz Spectrum Valuation Setting New Records

Results from the recent UK spectrum auction and the minimum price set by the Korean regulator show record 3.5 GHz spectrum valuation. UK operators paid £1.16 Billion ($1.64 Billion) for 150 MHz. In Korea, the regulator asked for close to $2.5 Billion for 280 MHz. For comparison, the 3.5 GHz UK spectrum is more than 5x the price paid… Read More »

The Cost of 5G

In my earlier post, I outlined a few myths about 5G to avoid the cascading technology trap. Here, I like to extend the discussion and share a few data points on the cost of 5G networks. Over the past few months, our team has analyzed vendors’ roadmaps and product features, assessed spectrum and its cost, and developed deployment… Read More »

WRC-15: Win Some, Lose Some

WRC15 concluded with new spectrum assigned for mobile services: L-band:  1427-1518 MHz is now assigned for fixed and mobile services. The L-Band is used for mobile satellite services. Technical measures need to be developed for co-existence with mobile satellite in 1518-1559 MHz. The 1350 – 1400 MHz was also a target for IMT, but it did not get… Read More »

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

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, the relatively short… Read More »

From LTE-U to LTE-DSA: Solving The Capacity Crunch

The proposal by Qualcomm to enable LTE operation in unlicensed band (LTE-U) received a warm response from some (e.g. Ericsson, Verizon) and not so warm from others especially incumbents with strong legacy in Wi-Fi in both the vendor and operator communities. The contentious issue center on co-existence of LTE and Wi-Fi in the same band as Wi-Fi implements… Read More »

LTE-Advanced, 3.5 GHz, Small Cells and Neutral Host Services: A Powerful Mix to Abundantly Increase Network Capacity

At a recent GTI event in Japan, Huawei demonstrated 770 Mbps peak throughput in a market trial of LTE-Advanced in 3.5 GHz spectrum. This was achieved with TD-LTE access mode with carrier aggregation. The trial showed 500 Mbps average throughput over multiple sites. Furthermore, Softbank demonstrated the ability to provide 1.2 Gbps peak throughput using 5-carrier aggregation in… Read More »
