PACE-IT.

– The evolution of cellular networking.» 1G cellular was only capable of voice transmissions.

» 2G cellular added simple data transmission capability (text).

» 3G cellular is the beginning of cellular networking.

• HSPA+ (Evolved High Speed Packet Access): a stopgap

between 3G and 4G; it has download speeds of 3 to 4 Mbps with

uplink speeds of 1 to 2 Mbps.

» 4G is still an emerging technology; it currently consists of LTE and

WiMAX.

» LTE (Long Term Evolution): uses an all-IP based core with high

data rates. It is compatible with 3G and WiMAX and has download

speeds of 7 to 12 Mbps with uplink speeds of 3 to 5 Mbps.

– Considerations on cellular networking.» Cellular connections can be intercepted (man-in-the-middle attack).

» Using the cellular system for network access usually involves

having to purchase an additional data plan.

• Adds an additional cost to owning a cell phone.

• It’s easy to exceed data plan limits.


– Worldwide Interoperability for Microwave

Access (WiMAX).» A technology that uses microwave transmissions for networking.

• The microwave stations must have a line of sight between the

stations.

» It is usually deployed at the metropolitan area network (MAN)

level, not at the wide area network (WAN) or local area network

(LAN) level.

» It was initially developed as a last mile alternative for situations

when DSL or cable were not available.

» Offers download speeds of 5 to 6 Mbps with upload speeds of 2

to 3 Mbps.

» Many municipalities are currently exploring the possibility of

developing WiMAX coverage to offer free or inexpensive Internet

connections to their citizens.

– Compatibility with cellular networking.» It is often considered a type of 4G connection, and WiMAX is

compatible with LTE; however, it is not compatible with 2G or 3G.


– Satellite» Uses microwave transmissions for over-the-air methods to

transmit voice and data.

• Can be an effective means of extending networks into hard-

to-reach places where other methods of connecting to the

Internet are not cost effective.

» Uses microwave radio relays as its method of transmitting

voice and data through the atmosphere.

• The relay stations must have a line of sight between them.

» Communication satellites form part of the microwave relay

network.

• The satellites are placed in known geostationary orbits and

the terrestrial microwave dishes are pointed at the satellite.

This satisfies the line of sight requirement for microwave

transmissions.

» Satellite connections can be affected by poor weather

conditions.

» Satellite connections tend to suffer from high latency issues.

• The signal needs to travel up to the satellite (typically over

22,000 miles above the Earth) and back down.



1G cellular could only handle voice traffic. 2G cellular added simple data

transmissions (text) to the mix. Beginning with 3G, true data networking

became possible. HSPA+ was developed as a stopgap between 3G and 4G

systems. 4G is an emerging technology that currently consists of LTE and

WiMAX. Cellular signals are easy to intercept and it is also fairly easy to

exceed a carrier’s data plan and incur additional costs.

Topic

Cellular Internet connections.

Summary

Because this is a technology that uses microwave transmissions to achieve

network connections, it requires a line of sight between stations. It is usually

deployed at the MAN level of networking. It was initially developed as a last

mile solution when DSL or cable were not available. WiMAX is compatible

with LTE, but not with earlier versions of cellular networking.

WiMAX Internet connections.

A technology that uses microwave transmissions to achieve network

connections (a line of sight is required between relay stations). Satellites

are placed in geostationary orbits above the Earth and the terrestrial

satellite dishes are aimed at them. Satellite based network performance can

be affected by atmospheric conditions and the networks tend to suffer from

latency issues due to the distances involved.
