Milestone of cellular networks and introduction of MVNO

2. Contents…
• Introduction
• From GSM to 5G
• Core Network
• Mobile Virtual Operator

4. Introduction
• The word wireless in dictionary defined “having no
wires ” .
• In networking terminology , wireless is the term
used to describe any computer network where there
is no physical wired connection

6. • Using Analog signals
• Listen to handset
• It's Speed was up to
2.4kbps.
• Frequency typically
150MHz & above
1G Wireless Technology

7. Drawbacks Of 1G
• Poor battery
• Poor voice quality
• Large in size
• No security
• Private Technology

8. 2G Wireless Technology
• It enables services such as text messages.
• It’s data speed was up to 64kbps.
• It provides better quality and capacity .

9. Drawbacks Of 2G
• Weaker digital signal.
• These systems are unable to handle complex
data.
• No data services

10. 2.5 G Wireless Technology
• 2.5G is a technology between the second
(2G) and third (3G) generation of mobile
telephony.
• 2.5G is sometimes described as 2G Cellular
Technology combined with GPRS.

11. Features Includes in 2.5 G:
• Phone Calls
• Send/Receive E-mail Messages
• Web Browsing

20. Mobile Virtual Operator
• A mobile virtual network operator (MVNO) is
a wireless communications services provider
that does not own the whole wireless network
infrastructure over which the MVNO provides
services to its customers.
