How wireless mobile and hotspot works

There is 3 component for Hotspot work with mobile phone / Tables and
CarPad (Hardstone):-

1) Mobile Telco Data Network / Mobile Broadband – Mobile provide
does provide data network to customer based on speed, data quota
and technology.
a. Speed – it’s based on Telco coverage location, speed limitation
setup (Download & Upload) and coverage congestion in each
Transmit terminal.
b. Data Quota – Each Telco has their owned mobile plan covers
Data limitation quota. Some mobile plan come with 2GB quote /
month follow by limited upload / download capacity.
c. Technology – Mobile coverage in Malaysia come with vibrable
speed capability . Some telco provide LTE, 3G, 2G, EDGE where
each technology come with different speed arrangement. More
details need to check with Telco.

2) Mobile Phone as Hotspot or Portable Hotspot
a. Receiving from Telco Lines (3G/2G/LTE/EDGE) – need to
consider mobile phone specification and channel to support
TX/RX speed. Majority of Dual sim card phone only support HIGH
speed TX/RX for one of the Sim card only. Also, You will get low
speed respond (TX/RX).
b. Normally TX / RX Broadband speed will drop when using
receiving / answering call on the same phone use as Hotspot
c. Connection to Client device via WiFi – This is private tunnel
speed between Hotspot provider (Mobile Hotspot) and Client
(Table / CarPad / another Mobile phone). Upload and download
speed will be same between this devices and speed limitation
(TX/RX) based on technology used:-
 802.11b offered up to 11 megabits per second (Mbps)
 802.11a and 802.11g offer up to 54 Mbps
 802.11n offers up to 300 Mbps
 802.11ac offers up to 1 Gbps (1000 Mbps)

3) Client (Table / CarPad / another Mobile phone)
a. Each WiFi client build with owned speed limitation (TX/RX) based
on technology used:-
 802.11b offered up to 11 megabits per second (Mbps)
 802.11a and 802.11g offer up to 54 Mbps
 802.11n offers up to 300 Mbps
 802.11ac offers up to 1Gbps (1000 Mbps)
