Evolving Wireless Services compete for spetrum

Wireless Coexistence (.PDF Download) | Microwaves & RF

To get an idea of just a few of the competing wireless standards, the reference “Wireless Coexistence” displays many of the common standards that are used today, and a few that we may see in the near future. In the reference, a color-coded chart provides a spatially accurate frequency mapping of the different operator bands of these common standards. A straight-edge can be used to see what different operator bands overlap. A rough and fine detail frequency mapping is provided
along with tables for each of the operator bands’ band number, uplink/downlink frequency, and bandwidth. All the frequencies represented in the tables are the center frequencies of the operator
bands.


Services mapped include:

1. FDD LTE
2. TDD LTE
3. CDMA
4. GSM
5. FDD UMTS
6. TDD UMTS
7. ZigBee
8. BlueTooth
9. UWB
10. WIFI
1. 2.4 GHz WIFI
2. 3.6 GHz WIFI
3. 5 GHz WIFI
4. 60 GHZ WIFI

In the evolution of wireless cellular standards,
all paths eventually lead to some form of
LTE or a WiMAX alternative
