Description
Technical field
The present invention relates to antenna technology, a kind of antenna assembly of base station particularly, and the method for utilizing base station to carry out networking and dilatation with this antenna structure.
Background technology
Mobile communcations system is to cover the coverage by a lot of base stations (BTS), existing antenna for base station has single-row antenna, has only feeding network in the vertical, and there is not feeding network on the horizontal direction, its directional diagram is approximate regular hexagon, adopt the base station of this antenna, therefore its coverage picture honeycomb one by one claims again " cellular system ".A mobile communcations system has a lot of honeycombs, and therefore, the network investment cost is very big, generally can reach the scale of hundreds of hundred million to more than one hundred billion.Obviously, the area that allows each base station cover big (just the honeycomb area is big), the quantity of base station is just lacked, and the cost of investment just lacks.But the capacity of a base station is limited, and area coverage is big, and capacity density is just little, and just needing when number of users increases increases new base station, and this situation is called the network capacity extension.Increased new base station, single honeycomb area coverage originally will reduce, so that reserve area coverage for newly-increased base station, be called network division or splitting.
A kind of desirable networking mode allows each base station area coverage big earlier when being initial networking, like this initial outlay little (because of user's networking be start from scratch ever-increasing), risk capital and risk are all less.Along with the user increases progressively dilatation again, just constantly carry out the network splitting later on.But, the dilatation of adopting network splitting mode except needs add necessary equipment, more than many fringe costs, localized network also will carry out complicated readjusting.Therefore the dilatation of network is " unsmooth ", and is not low-cost dilatation.Therefore, the low input of initial outlay and dilatation expensive just forms a pair of contradiction.
Existing wireless cellular system substantially all is with three sector form networking.The advantage of this mode is: 1, the directional diagram of antenna and overlay area form best fit; 2, sub-district standard relatively, the antenna direction between the base station is avoided mutually, makes interference minimum between the network cell.Be illustrated in figure 1 as three sectors and cover schematic diagram, circle is represented base station location among the figure, and arrow is represented the sensing of antenna for base station, and the sensing of the antenna in this structure is staggered mutually, is a kind of networking mode preferably, is therefore generally adopted.
In mobile communication system, along with the continuous increase of number of users, arrived certain the time, just need to increase new base station and carry out dilatation.But wireless telecommunication system particularly adopts the 3G wireless telecommunication system of WCDMA and CDMA2000 standard, and newly-increased base station dilatation also can bring more fringe cost except increasing necessary equipment, and for example, the site construction cost can be brought in newly-increased site.Because 3G covers and capacity is associated, the network planning and engineering construction be more complicated all in addition.Therefore newly-increased base station will increase the base station newly with regard to needs and original base station is on every side carried out the network planning together again, can bring new problem so again.Therefore, no matter newly-increased base station is at cost, technical, still a jump is arranged all on engineering construction, and this dilatation is rough.
For example need the coverage one of the base station among Fig. 1 is divided into three, Fig. 2 is the topological diagram after the dilatation.Behind the newly-increased base station, because the overlay area changes, original antenna all will be replaced by the antenna of new spec, and sensing all must be carried out interaction adjustment with the antenna of newly-increased base station with the inclination angle.And because the overlay area is irregular, adjust in any case, some dead bands also are difficult to obtain good covering.As seen will keep the network configuration of three sectors, the position of original base station all will change, and variation has also taken place coverage, will can produce bigger influence to original network like this.
For fear of above this rough dilatation, generally adopt the network planning principle of " disposable planning " at present, just in several years, the demand of capacity is planned networking.This planning mode guarantees that in several years network capacity all is enough, does not therefore need dilatation.But this also means in the wireless network networking and begins, and will arrange the base station of sufficient amount.This mode advantage is to have satisfied the requirement that need not increase new base station in several years, and shortcoming is that initial outlay is bigger, brings bigger investment pressure to operator.And the not minimizing of the quantity of base station, total site cost reduces.
Therefore, at present the networking mode of this " the disposable planning " adopted is under the prerequisite that does not solve the smooth expansion problem, take a kind of that do something against one's will, avoid the scheme of dilatation problem as far as possible, its shortcoming is:
1, the initial outlay cost is big; " disposable planning " is exactly to guarantee that network capacity is all enough in several years, need not carry out dilatation, this means and must once build up more cellular network, so the initial outlay cost is big, increases financial cost and risk;
2, site cost height; All there are some fixing expenses each base station, as the expense of building a station, storage battery expense and rental charge, and the site is many more, and cost is high more, because " disposable planning " needs the number of base stations of input more, so the site cost is higher;
3, planning difficulty; Because " disposable planning " needs site, more base station, base station, and does not have suitable site available sometimes in the position that needs are built a station, therefore cause difficulty to the network planning;
4, the present scheme problem of just temporarily having avoided dilatation after several years, along with capacity is saturated, is still had in the face of the problem of expensive dilatation.
