How Far The Wireless Technology Can Go

silicon460Silicon Valley technology company, AOptix will soon be implementing its wireless fiber technology, which is capable of beaming multiple gigabits of voice and data capacity over mobile carriers’ existing networks and long distances through radio transmitters. The wireless design will be able to keep mobile phone networks running during a catastrophe such as the recent Boston Marathon bombing. Zintro experts discuss how fast corporations will adopt the high-speed wireless technology.

Telecommunications professional, Mohammad Toossi points out several factors we need to take into account before implementing a wireless fiber technology, which will support an existing mobile network. “The radio transmitters, which communicate with the user equipment or more plainly the mobile station, must have the same technology as used in the mobile network’s existing technology to provide the additional coverage. Radio planning must be performed for tuning the radio parameters and optimizing the radio coverage. Subsequently, the wireless fiber network connection must be linked back to the mobile switching center and the serving GPRS support node as part of a UMTS core network or the evolved packet core as part of the LTE core network,” he explains. “This requires that there is no signal degradation under different physical or environmental conditions. Also, additional hardware must be introduced to support the wireless fiber connectivity to the radio network controller or the EPC equipment of a UMTS or LTE network, respectively.” Toossi also mentions the necessity to perform a cost benefit analysis in order to assess the additional capacity gains against the additional implementation costs. “Spectrum requirements must be considered to ensure that the required licenses are available. Obtaining licenses for the additional spectrum adds a significant cost for building the wireless fiber network. The introduction of the radio transmitters and the respective coverage planning can add significant hardware and radio optimization costs,” he adds. “The advantage, of course, would be the wireless fiber network’s ability to add significant bandwidth to support the additional voice and data traffic.”

Mark Csernica, an expert in mobile product development and network engineering, finds the new technology very promising even though he doubts that it will actually be helpful during an emergency. “This product seems to be targeting the network infrastructure and it could offer capacity solutions in the foreseeable future. The premise is that it would help provide capacity during catastrophic events like the bombing at the Boston Marathon or 9/11. I don’t see how this solution addresses capacity limitation on the RF link,” notes Csernica. “Especially when you have hundreds or thousands of users within a very small geographic area, all trying to use their cell phones at the same time. This solution does not seem to address that issue.”

Technology consultant, Steve Macke gives details on the new wireless technology and factors, which could limit the design process. “This is a free space optics technology using either 1310 or 850 nanometer beams with auto tracking on the receive end of the link,” Macke explains. “The limiting factors in designing the links is understanding how to calculate the link budget and configuring the link so that it is not only achievable but will be maintained with a reliability of 99.99 percent availability.”
