Chicago needs 84,500 small cells by 2015, world needs over ten million
October 19, 2011 // Jean-Pierre Joosting
Chicago will need approximately 84,500 small cells to deliver truly high-speed LTE by 2015, with acceptable coverage and speeds, according to analysis from Picochip. To provide LTE everywhere in the US around 1.8 million small cells would be required, based on estimations on data growth and usage across the country. This is in addition to residential femtocells and Wi-Fi.
The report was put together by Picochips CTO Dr Pulley, who also concluded that worldwide there would need to be in excess of ten million small cells to deliver comparable performance.
The US is already seeing widespread deployment of LTE, with basestations being deployed now to deliver next generation services. However, with relatively few users at present the networks are very lightly loaded, making it easy to demonstrate good data rates. In time, as there are more users, with a wider range of devices, the networks will become fuller and there will be a pressing need for many more cells.
Much of the discussion about LTE in the US has assumed 700 MHz, where the signal travels over a wider area compared to the higher frequencies elsewhere, however the purpose of LTE is for high speed data, said Doug Pulley, CTO at Picochip. My modeling includes actual traffic demands and network modeling. It shows why big cell towers, while still necessary, fall painfully short of being able to deliver on the requirements the citizens of Chicago will have by 2015. Small cells can deliver this and while the number may sound like a lot, these small boxes will be installed on existing street furniture and in buildings where you wont even see them.All news
