Efficient handling for subscribers' initial access to wireless networks is highly needed, particularly when the number of subscribers is expected to be significant, as, for example, in the case of new technologies like the Internet of Things (IoT). This paper provides a set of entry algorithms (based on 802.11 entry protocols) for a Time Division Duplex (TDD) mode to allow Subscriber Stations (STAs) to enter broadband base stations Access Points (AP) without significant delay. In this paper, a new method based on a pre-defined hashed backoff STA entry will be discussed. The proposed method is shown to achieve better contention window utilization by STAs, especially the time advance process and the collision-free hashed backoff method compared to the well-known exponential backoff method. It is worth noting that the proposed algorithm maintains compliance with industry standards such as IEEE 802.11.xx and it is currently used in real devices.
