Meaning
Wireless specifications for medium-rate cellular connectivity allow for the design of smaller and less expensive internet of things devices by removing the requirement for multiple antennas. Using lte cat-1 bis provides a migration path for legacy 2G and 3G hardware onto modern 4G networks. This standard supports downlink speeds of up to 10 Mbps.
Antenna Architecture
Physical design is simplified because the modem only requires a single primary antenna for operation. Unlike the standard category 1 devices that use receiver diversity, lte cat-1 bis eliminates the secondary antenna and its associated radio frequency front end components. This reduction in hardware complexity lowers the total bill of materials for the product.
Network Adoption
Compatibility with existing infrastructure depends on the software capability of the base station. Most global operators have updated their core networks to recognize lte cat-1 bis devices, allowing them to connect even if the cell was originally built for multi-antenna receivers. The device signals its single-antenna status during the initial handshake to ensure the network does not attempt to send data via a secondary path.
Cost Efficiency
Lower power consumption and reduced board space make this technology attractive for wearable trackers and smart meters.
