3) Glossary
Base Station or Base Unit is the WSD which is configured to bridge the packet flow to a router or point
of presence (PoP). Several CPEs or Client Units connect to the Base Unit
Bit Error Rate is the %age of bits which are in error on the radio link. The target BER can be configured
based on the current deployment conditions
Customer Premise Equipment or Client Unit is the WSD at the user end and registers with the Base
Unit.
Effective isotropic radiated power is the radio power in dBm measured at the output of antenna. It is
equal to the total conducted power + the antenna gains in dBi
TV White spaces are the unoccupied bands between TV channels which are used for broadband service
Wireless Regional Area Network is a wireless broadband specification defined by IEEE802.11a
specifications
White Space Device is a wireless communication device that works in TVWS
White Space Database is the database of usage of TVWS in a given region

Saankhya TVWS devices are fixed cognitive radio devices operating in TVWS bands ranging from 470-608
MHz. The devices can be configured as either Base radio or Client radio and are compliant with rules
specified in CFR 47 Part 15 subpart H of FCC regulations. When acting as a Base radio, device acts as a
master and Client radios act as slave. All the communication with external network (including with WSDB)
is handled through the Base radio
