Currently in my home, due to a thick concrete wall, the corner when my bed
& reading desk is located can't reach the broadband Wifi even if I connect
a Vonets VAR11N repeater below to the Telco's Wifi router:

I then used a USB Wifi dongle plus a 6m USB extender cable to connect to
my laptop with dongle bypassing the thick concrete wall (with direct line-of
-sight to the router) & could now consistently get the Wifi signal:

Q1:
However, for my iPad & my Android phone (which sometimes I read on the
bed), is there something equivalent to the Netgear dongle that I could use
with a USB extender cable? Ideally one solution for both iPad & Android
instead having to buy separate solutions.
Q2:
I ever seen a metal sticker which claims that once pasted onto the phone
will enhance the range of mobile phones' but lost that article : does this
work & can share an eBay/Amazon link to purchase?
Is this an Ethernet cable to your Wi-Fi router?
You can put a Ubiquiti UAP-AC-Lite Dual Radio Access point at the end of the cable. It comes with a POE device (or may come separately now) that goes at your Wi-Fi router and allows the Ubiquiti device to service the areas beyond the concrete wall.
I have one here and it works great. Gives me W-Fi on the second floor of my home.
