One of the key new feature of the iPhone 5 is LTE. All 3 telcos in Singapore supports 4G LTE, with M1 touting nationwide support as of writing. My mobile phone carrier is SingTel, and on their 4G network coverage page (http://info.singtel.com/4G#Network_Coverage-tab), it states 50% as of June 2012, 80% on December 2013 and 95% coverage across the island in early 2013.
As i commute between home and office, i have tested SingTel’s 4G speeds in both location. I will continue testing LTE in various locations and update them here.
Home – Ang Mo Kio Street 12.
Office – North Canal Road (Clarke Quay)
The lower speed in CBD area is probably attributed to the congestion that is slowly seeping onto the 4G network. As more users jump on the 4G LTE bandwagon, we may be back to the same overloading problem exhibited on the 3/3.5G network. The reduction in the download quota across all data plans would definitely weed out the bandwidth hogs, but telcos should also make sure that their infrastructure is capable of support the users subscribed to their service. A 4G capable phone is crippled without a decent mobile carrier to support it.
