Comba Telecom, a provider of wireless enhancement solutions, has launched its next generation of distributed antenna system (DAS) solutions for the North America market.
In a single system, the new generation of DAS supports up to 6 independent inputs – 700MHz, 850MHz, 1900MHz, 2100MHz, 700MHz MIMO, and 2100MHz MIM. Moreover, it’s optimally designed for ease of installation with a small footprint and sealed to weather all environmental conditions, according to company officials.
An RF-over-fiber solution, the new generation of Comba's point-to-multipoint DAS expands wireless network coverage and capacity via extension of cellular services from existing cell sites for both indoor and outdoor applications. Plus, it maintains the customary high degree of flexibility to optimize CAPEX and OPEX (News - Alert).
Unlike traditional network architectures, Comba's DAS deployed for new or additional networks eliminates the need for replacing existing fiber and antenna systems. Company officials said that the modular nature of the DAS means that wireless network operators are able to expand the reach of their voice and data services with multiple DAS rather than deploying additional base stations. This allows the system to accommodate growing capacity and coverage demands on the network.
DAS supports multi-operator, multi-system application, as well as all the major technologies such as GSM, CDMA, WCDMA, AWS, and LTE (News - Alert). Company officials said that it’s compatible with both indoor and outdoor applications.
Additionally, DAS supports all major modulations in mixed mode with high efficiency and linear MCPA up to 40W per frequency band – tri-band DAS model; and is compliant with 3GPP & FCC (News - Alert) standards.
Calling the latest generation of DAS solutions the result of intensive development in the company’s California and China R&D centers, David Luo, deputy director of Wireless Enhancement solutions division at Comba, said that they are effective point-to-multipoint solutions that provide effective coverage enhancement from single buildings to shopping malls, sports arenas to city centers and beyond.
Earlier this year, the company announced the completion of a project where it supplied wireless equipment to a major mobile operator for 2G and 3G wireless coverage at the site of the largest astronomical project in the world, located in Chile.
