Ericsson RRUS31 B25 + RRUS11 B26 These are the newest and greatest remote radio units to come from Ericsson.  The new Ericsson RRUS31  B25 should be fairly distinctive compared to the earlier RRUS11s and now the RRUS12s being deployed by ATT and Verizon. One of these new RRUS31s can do the job of two earlier RRUS11s thus reducing deployment costs for Sprint and complexity in deploying new sites and making it easier for users to spot as there are now 4 jumpers coming out of one RRUS31 rat
