malaysia LTE band ~ 2600mhz & 1800mhz

2600mhz is faster LTE speed (higher frequency can carry more data but weaker in terms of coverage or poorer indoor signal penetration capability)

1800mhz is slower LTE speed (lower frequency carry less data but better in terms of coverage n indoor signal penetration)

maxis, celcom n digi now got both band support
umobile & others telcos LTE now only got 2600mhz

that's y even u on maxis,celcom,digi's 4G LTE network, u may not experience the same with others if they tap on 2600mhz band rather than 1800mhz.

for handset, they auto log on band which yield greater signal level at that spot: so normally at indoor the phone may log on 1800mhz LTE band, not 2600mhz, as 1800mhz got better signal level indoor.

one may not really experience the true 4G LTE speed.

solution:
1. for pc user with software to lock on 2600mhz, hardware combine with external yagi lte antenna 2600mhz to get the signal.
2. for phone, tablet users, the solution is getting a 2600MHz LTE repeater.
