Apple’s LTE chip supplier Qualcomm announced on Thursday that it hopes to tackle cellular radio frequency band fragmentation with the first “single, global 4G LTE design” for mobile devices.
With over 40 cellular bands worldwide, many companies, such as Apple, need to release a slew of cellular models specific to certain carriers. Apple made the iPhone 5 compatible with LTE networks, but due to 4G LTE and legacy radio fragmentation, in which carriers use different radio bands, the company made two separate GSM models and one CDMA model.
The current iPhone 5 models include: GSM model A1428 for LTE bands 4 and 17; GSM model A1429 for LTE bands 1, 3, and 5; and CDMA model A1429 for LTE bands 1, 3, 5, 13, and 25.
Qualcomm’s new RF360 Front End Solution is a family of chips that would both improve RF performance and end LTE band fragmentation by helping OEMs develop mobile devices that support all cellular models (LTE-FDD, LTE-TDD, WCDMA, EV-DO, CDMA 1x, TD-SCDMA, and GSM/EDGE).
“By combining the new RF front end chipsets with Qualcomm Snapdragon all-in-one mobile processors and Gobi LTE modems, Qualcomm Technologies can supply OEMs with a comprehensive, optimized, system-level LTE solution that is truly global,” explained Qualcomm in a press release.
The Qualcomm RF360 front-end solution purports to cut poor usage and improve RF band interference and specifically features the following components: Dynamic Antenna Matching Tuner (QFE15xx), Envelope Power Tracker (QFE11xx), Integrated Power Amplifier / Antenna Switch (QFE23xx), and RF POP (QFE27xx).
