-- Because the channel can be popped from before the thread first executes, there may not be data on the stack.-- in that case use :demand() instead of :pop() because :demand() will block until there is data on the stack and then return the data. print (love. thread. getChannel ("test"): demand ())-- The thread can now finish. end
Channels are typed, so that a channel of type chan T can only be used to transfer messages of type T. Special syntax is used to operate on them; <-ch is an expression that causes the executing goroutine to block until a value comes in over the channel ch, while ch <- x sends the value x (possibly blocking until another goroutine receives the ...

Even when the return and forward channels use the same medium, their differences often dictate the use of very different data modulation and coding techniques. For example, in a star radio network, only the central hub transmits on the forward link, so channel access method is a consideration only on the return link.
Higher-order functions are functions that can either take other functions as arguments or return them as results. In calculus, an example of a higher-order function is the differential operator d / d x {\displaystyle d/dx} , which returns the derivative of a function f {\displaystyle f} .
The reverse link (sometimes called a return channel) is the link from a mobile user to a fixed base station. If the link includes a communications relay satellite, the reverse link will consist of both an uplink (mobile station to satellite) and a downlink (satellite to base station) which together constitute a half hop.
DVB-RCT (Digital Video Broadcasting - Return Channel Terrestrial) provides a method by which the DVB-T platform (and in theory also the DVB-T2 platform, but DVB-T2 probably trialled first about 5 years after last DVB-RCT field trial) can become a bi-directional, asymmetric data path using wireless between broadcasters and customers.
A broadcast channel is a channel that provides a broadcasting service, i.e. that sends data addressed to all users in the network. Cellular network examples are the paging service as well as the Multimedia Broadcast Multicast Service. A multicast channel is a channel where data is addressed to a group of subscribing users. LTE examples are the ...
