Abstract

A modular telecommunications system configured for wireless telecommunication in accordance with a pre-selected standard. Modular units are adapted to be secured within other items of electronic equipment for establishing a telecommunications link with a wireless network. The modular telecommunications unit comprises a housing for mounting a radio transceiver therein. The housing includes a plurality of contacts arranged along a first end, the contacts being adapted for engagement with contacts in the electronic equipment, and at least one radio connector disposed along the second, opposite end of the housing and connected to the radio transceiver within the housing whereby the radio transceiver can be coupled to an antenna to enable communication therefrom.

Claims

1. A system comprising:

an electronic equipment having a module mating connector;

a modular telecommunications unit comprising;

a housing having a first end and a second end;

a module coupling connector disposed on the first end of said housing, said module coupling connector being adapted for engagement with the module coupling connector being of said electronic equipment;

an antenna coupling connector disposed on the second end of said housing; and

a radio transceiver being mounted within said housing and being in communication with said module coupling connector and said antenna coupling connector;

wherein said electronic equipment further includes an antenna and an antenna mating connector, said antenna mating connector being in communication with said antenna and adapted for engagement with said antenna coupling connector for enabling communication between said antenna and said radio transceiver;

wherein said electronic equipment is constructed with a slotted portion having a first slot end and a second end, said module mating connector being disposed on the first slot end of said slotted portion, and said slotted portion being adapted for receipt of said housing therein; and

wherein said slotted portion of said electronic equipment includes a closure member disposed adjacent to said second end of said slotted portion for securing said housing of said modular telecommunications unit within the slotted portion of said electronic equipment, wherein said antenna mating connector is disposed on said closure member, and wherein said antenna of said electronic equipment is connected to said antenna coupling connector through said antenna mating connector on said closure member.

2. A method of providing telecommunications from an item of electronic equipment comprising the steps of:

providing a modular telecommunications unit having a transceiver housed therein;

disposing a PCMCIA coupling connector on said modular telecommunications unit with said transceiver coupled thereto;

programming said transceiver for telecommunications in accordance with more than one preselected bi-directional wireless telecommunication standard;

providing a mounting structure for said modular telecommunications unit in association with said electronic equipment;

disposing a mating PCMCIA connector within said mounting structure for the engagement of said coupling connector;

providing an antenna for connection to said modular telecommunication unit; and

wherein said step of providing the mounting structure includes the step of forming a slot having a first end and a second end within said electronic equipment, disposing said mating PCMCIA connector adjacent to the first end of said slot for the engagement of said coupling connector, and providing a closure member adjacent to the second end of said slot for securing said modular telecommunications unit within said slot.

3. The method of providing telecommunications as set forth in claim 2 and further including the steps of:

providing an equipment antenna connector being in communication with said antenna;

providing a module antenna connector being in communication with said transceiver of said modular telecommunications unit; and

positioning said equipment antenna connector on said closure member and said module antenna connector on said modular telecommunications unit, such that said equipment antenna connector connects with said module antenna connector when said closure member secures said modular telecommunications unit within said slot of said mounting structure.

4. The method of providing telecommunications as set forth in claim 3 and further including the steps of:

disposing said modular telecommunications unit within said slot of said mounting structure such that said PCMCIA coupling connector connects with said mating PCMCIA connector; and

closing said closure member such that said closure member secures said modular telecommunications unit within said slot of said mounting structure and said equipment antenna connector connects with said module antenna connector.

5. The method of providing telecommunications as set forth in claim 2 and further including the step of disposing said modular telecommunications unit within said slot of said mounting structure such that said PCMCIA coupling connector connects with said mating PCMCIA connector.
