Mobile data speeds may have finally overtaken broadband speeds, but the network coverage is still very poor. While operators do try their best to improve the network coverage, the lack of free radio waves, and big buildings do make things tougher for them. The advancement in mobile radios do help a bit, with better reception even in low-signal areas. Most operators are turning to using Wi-Fi to improve network coverage in low-signal areas. T-Mobile in the United States being a prime example of this.
Orange in the U.K also applies a similar technology. The company’s phone come with a signal boosting technology (UMA) that will use the Wi-Fi network in low-signal areas to boost the network reception. Sadly, the UMA feature would not work if users flashed a custom ROM on their handset.
An XDA member has, thankfully, found a way to get the UMA feature to work on the Samsung Galaxy S2 running a custom ROM. The mod works on the stock Samsung firmware based ROMs as well as AOSP based ones. The mod does require the use of a custom kernel like Siyah Kernel, though. The mod works on the Galaxy Note as well as reported by the users over at XDA forums.
Interested Galaxy S2 and Galaxy Note owners can download the CWM flashable zip file of the mod from here.
