I got my own Unifi Air + modem although sales advisor told me will not get full performance but at least better than 8Mbps cap on bebas.

3km away from 4G coverage my findings as below:
- Using band 5, hovering @ 11Mbps on DWR-953, while 4-6Mbps on B618, RSRP -90dB
- Using band 40, B618 able to go up to 16Mbps, RSRP -104dB
* Tested when SNR value is at min 10.


** Before Unifi Air comes into picture, band 38 & 40 were widely detectable in my places. But now band 40 is spotty and band 38 is no where to be found.
** Sim activated 1 hour after application.
*** No "warranty" sticker placed at the SIM slot

I tested with DWR-953 (supports B5, B38 and B40) to compare with B618.

It is able to work flawlessly on B5 even away from actual LTE coverage about 3km away. Just check your device LTE band frequency it supports.

Now my DWR-953 putting up for sale for those uses Unifi Air without contract.

Yes. I have my own unifi bebas both also has the same coverage. I helped you checked the data sheet. It is supporting band frequencies of 900/1800/2600/800 MHz

Only 2600 Mhz which is band 38 is supported for your device. From my experience in Bdr Sg Long band 38 is missing after unifi air has launched.

Yeah too confusing, best to try out with unifi mobile sim. But from dlink router we cannot know which band it connects. Check your model revision number, I found there's B, C1 and C3 revision for dwr-921. C3 will have all the bands I believe.

If you have B618 + HManager apk for android to configure b618.

Unifi mobile coverage = Unifi air coverage.

I have tried before subscribing to Unifi Air. Although the sales person gave me warning due to coverage is not covered (about 2km away from actual coverage shown in website), I can confirm it should work. After getting the Unifi Air, both Unifi Mobile and Unifi Air shares the same LTE tower.

In my area for Bandar Sg Long, B40(2300) is strong while B5(850) is spotty.

With my signal status range:
RSRP -111 to -100
RSRQ -11 to -7
SINR 6 to 11

Able to get speed around 15Mbps to 30Mbps download speed and 1Mbps to 3Mbps upload speed.

FYI, I tried to strengthen the LTE signal by using "4G LTE" antenna 88dbi booster which is total failure as B618 has way much more stronger signal reception. That antenna only serves as outdoor antenna where "good signal reception" area is outside which is not suitable for your previous LTE router to be exposed to any weather conditions.

Just don't buy the 4GLte brand, the shaped like a book claiming 88dbi. It only works as extender in outdoor. Get the shark fin shape one from Huawei which I'm planning to try it out.

Ensure the connector given is TS9 for B618 since there is no description mentioning about it. Only works when you are in high rise and balcony is facing the tower.

Yes, direct connect only. Can see whether it is connected properly through the router's interface as by default it is set to auto.

COVID period like this the shipping day estimates may varies. Just hope for faster shipping and he could be putting the longest delivery period just to avoid getting frustrated customers to complain bah. I haven't bought mine yet as monthly budget already overspent and shrunk.
