Ubiquisys indoor GM7 multi-mode cell chosen for major small cell programmes

New high-availability small cell provides capacity and coverage indoors where 70% of mobile data is consumed at a much lower total cost of ownership than small outdoor and macro cells

Ubiquisys indoor GM7 multi-mode cell chosen for major small cell programmes

Ubiquisys, the developer of intelligent small cells, announced this week (27 November 2012) that its GM7 multi-mode cell for indoor public spaces has been selected for deployment in significant small cell programmes in South Korea and Japan. 

The new cell, which supports LTE, 3G-HSPA+ and Wi-Fi, is specifically designed for use in a wide range of public spaces such as stores, malls, and transport hubs. The GM7 features ActiveCell(r) high-availability software with 99.999% uptime proven at thousands of indoor metro sites in South Korea and Japan.

Ubiquisys notes that mobile carriers have been actively shifting their focus towards indoor public access small cells and away from outdoor models, where they face significant deployment challenges surrounding site acquisition, backhaul and power. 

This is unsurprising, says the company, as more than 70% of mobile data is consumed indoors, where there is an abundance of IP backhaul, power and motivated site owners. Indoor small cells also provide maximum re-use of valuable spectrum assets and a stronger signal for mobile users.

Chris Gilbert, CEO of Ubiquisys, said: ‘Outdoor small cells have a role to play, but the problems of site acquisition costs, backhaul and power coupled with the majority of data usage occurring inside is making indoor metrocells more compelling to carriers. Indoor small cells have clear technical and economic advantages, provide a natural integration point with Wi-Fi, and can be fully deployed in just three months. That's why carriers are increasingly making them the first choice for multiplying data capacity and coverage.

Carrier-grade multi-mode flexibility with Texas Instruments 

The Ubiquisys GM7 uses Texas Instruments' high performance TMS320TCI6614 chipset solution providing simultaneous LTE and 3G-HSPA, which Ubiquisys ActiveCell(r) software can dynamically balance according to demand. The underlying KeyStone architecture reflects TI's long experience as a leader in base station infrastructure, with specific features designed to handle the hundreds of data users these cells will serve. 

These include specific hardware acceleration for Layer2, including queuing engines and powerful Direct Memory Access (DMA), separate Layer3 processing and a dedicated network processing engine to handle complex backhaul packet processing.

Lowest total cost of ownership

Joe Madden, principal analyst at Mobile Experts, commented: ‘Together with our Advisory Panel of mobile operators, we recently conducted a study into the total cost of ownership (TCO), for serving mobile data to indoor public spaces, comparing indoor small cells, outdoor small cells and macro cells. The figures show that the indoor small cell TCO is approximately half of the outdoor small cell TCO, and five times lower than the macrocell TCO for each MB of data served.’
