MI-149
MI-149
The Kaelus MI-149 is designed to enhance cell uplink coverage in 1800 and 2600 MHz bands through improved system noise figure, reducing operational and capital expenditure. Key features include improved base station sensitivity, internal diplexing on antenna ports, excellent noise figure performance, full AISG operation, and RET antenna support. The unit is compact and lightweight for minimal visual impact.
- Downlink: Passband for 1800 MHz is 1805-1880 MHz and for 2600 MHz is 2620-2690 MHz. Insertion loss is 0.5dB typical for 1800 MHz and 0.4dB maximum for 2600 MHz. Return loss is 18dB minimum, with a maximum input power of 200W.
- Uplink: Passband for 1800 MHz is 1710-1785 MHz and for 2600 MHz is 2500-2570 MHz. Gain is 12dB nominal, with a noise figure of 1.5dB typical.
- Electrical: Impedance is 50 Ohms. The unit operates in AISG mode when valid AISG 2.0 frames are detected, with a power consumption of less than 4W in AISG mode.
The unit operates within a temperature range of -40ºC to +65ºC and has an ingress protection rating of IP67. It offers lightning protection and complies with various EMC and safety standards.
The dimensions are 224 x 109 x 209 mm, and it weighs 6.7 kg. The unit is powder-coated and can be mounted using pole or wall brackets.
Various configurations are available, identified by part numbers such as MI-14901 and MI-14902, with options for different AISG modes and connector types.
Catalog excerpts
Designed to be deployed in collocated 1800 and 2600 systems, the Kaelus MI-149 enhances cell uplink coverage in 1800 and 2600 through improved system noise figure, thereby saving operational and capital expenditure. Microdata Telecom rebranding to Kaelus! Microdata Telecom and Kaelus have had combined operations since Oct 2019 when Microdata acquired Kaelus. We strongly believe that by operating under one global brand we will clarify our strengthened position in the telecom market and from January 18th 2021, we are unifying the brands to Kaelus. • Improved base station sensitivity through gain in the 1800 and 2600 uplink • Internal diplexing on the antenna port of 1800,2600 bands: 2 Antenna ports • Excellent noise figure performance • Full AISG operation and RET antenna support, AISG2.0 compatible • Small and light for minimum visual impact © Kaelus 2020.
