Can LTE-M1 be deployed on existing base station equipment or do Verizon/ATT simply have to provision their existing basestation radios?
It is just a software upgrade to existing base stations.
what bands are Verizon/ATT using? and for NB-IoT?should i design my device with a penta-band antenna or just sub-GHz?
Verizion is Band 1 (700 MHz). I'm not sure about ATT.
