Minimal form factor Multi system MIMO technology ANTENNA SITE SOLUTION
Optimal. Multiple. MIMO Given the prodigious increase in the applications that utilize wireless local area network technology and the high data rate communications, antennas with optimal MIMO (Multiple-Input Multiple Output) performance and multi-band technology help enhance operator's ability in ensuring network performance and upgrading user experience. Investing in solutions to increase performance and reliability is no small undertaking, here are the key considerations when modernizing current network Adopt multi-band antennas for today s and future's needs of additional spectrum Choose devices designed to minimize passive intermodulation (PIM) Minimize interference resulting from co-sited components Modernizing network with ease Implementation of co-site solution has become the mainstream in the development of mobile communication, Comba's antenna site solutions embrace multi-band base station antenna, multi-band combiner, and same band combiner to benefit all systems with reliable performance, yet tackling site space limitation and interference. Comba's antenna site solutions deliver support to all network technologies future-proof components excellent PIM performance high reliability assurance Our solutions adapt to LTE network evolution, helping operators implement a smart and quick network roll-out of new services with efficiency for immediate or long-term planning.
Antenna site solution designed for long-term LTE network requirements To meet requirements for the coexistence between LTE and GSM/UMTS networks, each site requires multiple bands for coverage. Comba's multi-band onsite antennas with integrated RET technology help operators overcome the restrictions on the number of onsite antennas facilitate cost-efficient site sharing advance capacity-generating MIMO deployments Multi-band, multi-port An extendable platform supports up to 10+ Bands from 694MHz to 3800MHz Future-proof connectors 4.3-10 connectors fit many designs and improve PIM MIMO capable Allows up to 4x4 MIMO on the low band and up to 8x8 MIMO on the high band One antenna for all coverage - available for extending to super multi band without compromising on radiation. Integrated RET (Remote Electrical Tilt) control device enables operator control independently in case of sharing for antennas Compact size supports 2 low and 3 high band SBS arrays in only 445mm width Visual down tilt indicator withstands even the harshest environment (e.g. freezing point) AISG compliant Antenna Interface Standards Group is a protocol used to control interface for antenna line devices such as RETs. Comba's antenna products are designed to be fully compliant to AISG standards, together with the RET capabilities, our antenna site solutions enable wireless operators to optimize their network s performance while holding the line on OpEx and CapEx costs.
What can Comba's combiners bring to operators? Save CapEX by reducing RF equipment requirements Speed up site infrastructure Improve PIM performance Fast roll-out, reliable RF performance Comba's multi-band and same band combiners are designed for cost effective antenna and feeders sharing for site or other outdoor applications. Our multi-band combiners combine specific frequency spectrums without incurring high insertion loss, allowing operators to integrate different frequencies into a common antenna system with greater ease and efficiency. The multi-band combiners support all major air interface technologies and cover global frequencies with Variety of choice diplexers, triplexers, quadplexers and pentaplexers for sharing and co-siting purpose 4.3-10 connectors fit for multi-port development and support high capacity PIM improvement up to -160dBc Comba's same band combiners enable operators to use current feeders and antennas to support the legacy 2G/3G services with the new 4G LTE service, maximizing the value of existing infrastructure and accelerating the ROI of the LTE services. Pass-band available factory tunable for desired signals High power handling and low insertion loss maximizes system performance High band-to-band isolation minimizes interference Comba's combiners are compatible with all LTE radios, as well as with all 2G and 3G BTS systems. The devices are built with preconfigured DC/AISG by-pass to route RET signals directly to the correct port, and ensure RF performance meets specifications in harsh, real-world environments.
