According to reports, OPPO used a modified version of the R15 to test 5G connectivity. In order to do this, the smartphone was equipped with a Qualcomm Snapdragon X50 5G modem, which is capable of delivering speeds of up to 5Gbps. The test was conducted on 3GPP Release 15 NSA standard with the 10 MHz bandwidth of 4G LTE Band 5 and 20 MHz bandwidth of 5G NR n78 band. OPPO says the connection to telecom signal and data links on the modified OPPO R15 will promote the maturity of 5G smartphones and lays down a solid foundation for the company to release commercial 5G smartphones next year. It should be noted that OPPO is actually the first Chinese Android OEM to have successfully completed 5G signaling and data links testing on a commercially available mobile phone.
However, OPPO is not the only manufacturer that is currently working hard on becoming the first company to launch a 5G smartphone next year. Lenovo Vice President Chang Cheng had claimed last month that his company will be the first to launch a smartphone with 5G connectivity. The Lenovo 5G smartphone is expected to be powered by Qualcomm’s next-generation Snapdragon 855 mobile chipset. Huawei is another manufacturer that is making a similar claim. Like Lenovo and OPPO, Huawei too expects to launch its first 5G smartphone next year. Some other brands like OnePlus and LG are expected to release their first 5G smartphones in the first half of 2019.
