Who Makes What: Next-Gen Wireless Infrastructure
The boom and the bust that's occurred in the third-generation (3G) wireless market means that it's time for a roll call on what companies still make equipment in this space.
For starters, we've compiled a list of categories that we believe covers the key components of a 3G network and the vendors that sell them. Now we want your input: If you think there are additional categories needed, or if we missed a startup fresh out of the VC incubator, tell us by jumping on the message board or sending email to [email protected].
A wireless network of any stripe is mind-numbingly complex, so to keep our taxonomy to a manageable size, we've focused on two network areas – the radio infrastructure and the packet core – because these undergo the most changes during the evolution from 2G to 3G. Those categories are:
- 1) Base Transceiver Stations
2) Node Bs
3) Microcells and Picocells
4) Base Station Controllers
5) Radio Network Controllers
6) Packet Data Serving Nodes/Foreign Agents
7) Home Agents
8) Serving GPRS Support Nodes
9) Gateway GPRS Support Nodes
10) AAA Servers
That brings us to the next step: Once we've complied a final list of equipment categories and vendors, we’ll use it as the basis for future reports.
So fire away. And if you need a 3G refresher course first, visit A Wireless Taxonomy.
